Dynamic HTML ToolTip that loads OnHover/OnMouseOver

right now i have a web app that has a repeater (rather large) with a literal for one of the columns. this literal is a number based on the amount of entries and on load has javascript added to it that displays row specific information built from a database when you hover over it. the problem is that every time the page loads, every tooltip is loaded. i want to only go to the DB and get this info when they hover over that literal. so onmouseover of this literal would trigger an event that builds the tooltip and displays it as before.

i've searched this forum (which by the way isn't efficient) along with some good old Google hunting with no luck. can anyone point me in the right direction? oh yeah, i also would prefer not to use some random 3rd party tool. =)

This is fairly easy. Follow this tutorial:http://ajax.asp.net/docs/tutorials/ConsumingWebServicesWithAJAXTutorial.aspx except that in the 'OnComplete' javascript function that fires when the web service returns, have it fill whatever container you're currently using to display the tooltip (mostly this ends up being the title attribute of one element or another).

I'll check it out and see how it goes. Thanks for the reply =)

Dynamic Controls in ASP.NET AJAX context - Controls seem to be disappearing.

I have a Web Application that I am developing and I have run across aserious problem. Due to the fact that the Application entails a lot ofdetails and code I am not able to give an actual sample of the problemI am running into. However, I have created the same problem on asmaller scale in a temporary Application.

Theissue revolves around ASP.NET AJAX and its ability to track Dynamicallycreated Web Controls. On the sample Application below I have a Pagethat contains 8 Buttons. Whenever one of those Buttons is pressed thePage performs an Async PostBack which causes the Page Load Event toexecute followed by the Event Handler for the Button pressed. In theEvent Handler the Button gets removed from the Page. The desiredeffect is that when someone pressed a Button it will in turn remove theappropriate Web Control (Button) from the Page. Everything works finewith one very big exception: ASP.NET AJAX seems to have a problemkeeping track of the Controls on the page.

For example, if youcopy and paste the code at the bottom of this post into Visual Studioand press the Buttons in the following order you will notice someButtons simply disappearing:
2 - 7 - PostBack - 4 - 1 - PostBack

Onevery important part of this demonstration is that the Button is notonly removed but its also prevented from Rendering. If you take outthis line of code everything works fine but in my actual Applicationthe Control is not Rendered and the results match that of what happensin the temp Application.

So my question is, whats happening inthe background? It seems that removing the Control does not prevent itfrom being Rendered and if you manually prevent it from Rendering bysetting its Visible Property to False then ASP.NET gets completelythrown off as to whats going on.

I know its rather difficult toanswer a question like this because you can't simply provide analternative to the problem so any help is greatly appreciated. I amsimply trying to figure out whats going on in the background so I canfind a solution to my real Application.

After 3+ days of brainstorming, testing, debugging and everything I could throw at ASP.NET I have found a solution.

Theproblem lies not within ViewState, not with ASP.NET's Control Tree (nottechnically), not within the Code itself but in how ASP.NET handlesdynamic Controls in regards to their ID's.

If I modify my codeabove as demonstrated below everything works just fine. You wouldthink that incrementing the ID's instead of assinging the same ID's tothe same Controls would do nothing but for some bizarre reason thatshow it works.

My problem in my real Application is very similiarto this problem and I have in fact solved my problem. Its funny how ifI had been able to pin-point this problem several days ago I would beway beyond this. Oh well, thats ASP.NET.

Dynamic CollapsiblePanels

I was wondering if anyone has ever dynamically added CollapsiblePanels to a web form based on data from a database? Do I need to create a separate instance for each panel area I need or can I do it with one CollapsiblePanel control? Basically what I am looking to do is create something like the following:

TITLE1
>FIELD1
>FIELD2

TITLE2
>FIELD3
>FIELD4
>FIELD5

All data is being pulled from a database so, the fields are added to a Panel based on the title they are associated with. My workflow is currently to:

1) Query the database to get the information
2) Loop through the records to add controls to a new content panel
3) When all of the fields have been added to the contents panel, create a new CollapsiblePanel control and add it to the form
4) Loop until there aren't any more groups

This seems to kind of work but I continue to get an error stating that I have two or more controls with the same ID. I believe I have traced this to the adding of the multiple CollapsiblePanels. I am generating a random number to assign to the CollapsiblePanel every time one is generated but, the error still happens.

Any ideas what could be going on here?

I was in the same situation and came up with the following code. I hope it helps. I use Patterns and Practices (v3.0) so use your method of choice to obtain the data. I make use of a place holder to dump the controls so make sure you put one on your form and call it plcHolderForPanels for this example. Good luck :)

dynamic cascaded drop down

Hi..

well in my web page based on a parameter user selects i need to create contents dynamically

for eg if A is passed than page will have only 1 drop down but if B is passed it might have 7 8 drop downs in it..

this is one part of the problem..once i am able to create them i need to address there selection index change even which will call again some fucntion

which will reload all othr drop dwon whch were created dynamically

so its kind of generating cascaded drop down dynamically and the parent control id could be more than one

Can some one help me out

in case any one is here wondering what happened to the problem

the solution is same as

Dynamic Atlas page

I am making a completely dynamic web page. I want to use Atlas for UI handling.
This means that all atlas controls I create in codebehind (But sometimes a template would be useful, but only html template - atlas code should be generated dynamically). The main idea is that while you enter data, page updates itself and either edits data or changes whole behaviour. So I have some questions
1) Where can I see which classes create which elements in Script tag?
2) Is it possible at all to dynamically change behaviour - for example, to make the same html button call different actions or to completely change part of html (span element) and accordingly change atlas scripts?
3) how to dynamically add atlas controls from codebehind and avoid rendering visible control - make only atlas script?
4) how to make visible part of atlas control to appear somewhere else not after closing HTML tag?It shouldn't work that way, I think. Atlas is more client side then server framework..point is to make smart client webapplications which requests only actually needed data from server. You can create all controls from code, but on client side it will look same as if you create them much easier way in designer.
It's all my personal option

You didn't understand the problem - I want to put more action in client-side. For example, when filling out order form, I want to check data (and autofill some fields) without postback.
But the way I want to build UI is dynamic - I make product definition (what data are necessary for particular product) and screen definition (where these necessary data show up in UI). And then I have helper class that goes through those definitions and creates UI controls. Currently I can create native ASP.NET controls, but I would like to use ATLAS instead.
So the problem is that all examples of ATLAS scripts I have seen so far are statically typed in *.aspx page. But I want to create those scripts at runtime using Microsoft.Web.UI.* classes. But I cannot find all classes that correspond to examples in static scripts. For example, how can I programmatically create serviceMethod tag?
Not all client-side Atlas controls have a server-side version yet. Forexample, there is no serviceMethod Atlas server-control yet.
You would have to write them yourself, or wait until a new version ofAtlas is released which includes more server-controls for the Atlasclient-side controls.

Where can I get more info on how to create a class that creates ATLAS script? What should I inherit from, what methods need to be implemented, etc?

Dynacly add scriptmanager when needed?

Hi,

I'm trying to create a Web User Control that uses asp.net Ajax. I'd like it to find out if a scriptmanager already exists in the page and, if not, add ti dynamically. Would such a thing be possible?

Thanks in advance for any help.

Regards,

Stefan

Yes its possible, you can check if ScriptManager is registered. FindControl(); or you can added it in the Master Page

http://forums.asp.net/thread/1441992.aspx

http://forums.asp.net/thread/1436775.aspx

Thanks for your quick reply. But how would I use FindControl if I don't know what the name of the scriptmanager would be?

I'm thinking of a situation where my control gets used in combination with other ajax controls, or gets used multpile times on a form. (Actually, my control would be a DotNetNuke module)

Any ideas?

If you didn't change it ScriptManager1

I know, but the hard thing is, that all controls get added to the page dynamically by DotNetNuke. This means I'm pretty sure the name won't be ScriptManager1...

So if there's no other way than to use findcontrol, the only option would be to add the ScripManager to the page itself somehow.

Thanks for your help.

hello.

you can get a reference to the ScriptManager control by using the static GetCurret method. If there's already a ScriptManager on the page, you will get a non null value.

I've put together an example ofUsing Control Adapters to automatically attach AJAX Extenders to ASP.NET Controls, which isn't exactly what you want, but there is code for walking through the controls on a page to see if there is already a ScriptManager or ScriptManagerProxy ...

http://damianblog.com/2006/11/16/adapters-and-extenders/

Damian

hello.

hum...why are you going through a cicle to get the scriptmanager control?

Because I'm doing it from an HttpModule ... and also because I didn't know of the static method :-)

Not sure if it will work in the module though ... will have a go.

Damian

hello.

well, i guess it might not work if you haven't instantiated the master page (which is easily solved by just "touching" the property)

Hi again, it's been a while since I had time to figure this thing out, but your answers look promising. Thanks a lot so far.

DropShadowExtender and target panel separate when window is resized

So here's what's up.

I've got a horizontally scrolling asp panel.

In the panel is a datalist which repeats horizontally.

I have a web user control set as the item template. The user control makes use of the DropShadowExtender.

It works beautifully, until the window is resized, then the shadows and user controls part their ways.

Any ideas?

DropDownList in an AJAX modal popup window

We've developed a multicolumn dropdown listbox that works great on a standard Web form, but it's been giving me a lot of grief trying to get it to work in an AJAX modal popup window. For some reason, either the dropdownlist or the popup window's height ends up getting set to -2px, which causes the program to come to a screeching halt.

I don't have any such problem if I use a standard dropdown listbox, but I need to show both a code and a description in the dropdown and a standard dropdown comes with its own set of problems in that circumstance. To separate the description from the code and to evenly align the description, I modified the DataText property by setting it equal to the code plus a tab character plus the description thusly, ddList.DataText = "Code" + Chrw$(9) + "Description". Once it's rendered on the screen, I view the source and it shows all the codes and descriptions with the tab between them allowing the descriptions to be aligned properly. But the browser strips out the tab character and replaces it with a space.

I'm about to give up on this and was wondering if anyone has had any luck doing the same thing?

Allen A.

There is no tab in html. It will be replaced by (or non breaking space). You can add a definite number of non breaking space to format your listitems. Sorry not able to give simple solution.

dropdownlist

Hello All,

I have three dropdownlists and a textbox on my web page. The dropdownlists display the Day/Month/Year respectively.

I set the dropdownlists to display today's date when the page loads and the textbox displays the values from the dropdownlists as a single string value.

How can i dynamically change the dates in the dropdownlist for example ( instead of december 2007 to december 2008)and have the new changes displayed in the textbox?

The easiest way is to put your textbox inside an update panel like this:

 
<asp:UpdatePanelID="updPanel"runat="server"UpdateMode="Conditional">
<ContentTemplate>
<asp:TextBoxID="txtDate"runat="server"/>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTriggerControlID="DropDownList"EventName="SelectedIndexChanged"/>
</Triggers>
</asp:UpdatePanel>
 
Now in the SelectedIndexChanged event handler, just set the textbox to the new text. That's it!
 

Thanks oswaldorb,

It works but not as i want it to.

I would like the default date to be the current date for example 13/12/2007 when the page loads initially.

But when i try to do change the default date, i get an error

Please help!

DropDownExtender throwing 404 "File does not exist" error

I have used DropDownExtender in my projects and it works fine. However if I check the HTTP log using Web Development Helper (fromwww.nikhilk.net), I find a 404 response as it tries to get a file/resource "null" from the current folder (e.g. SampleWebSite/DropDown/null). I can get the same "error" when I run the sample web site of AjaxControlToolkit. Is this a bug? Although it works fine even with the 404 response, it bothers me because my application does catch it and log it in the event log.

Hope someone can tell me how to get rid of the 404 response.

Thanks

Edwin

Hi Edwin,

This is the internal behavior of the DropDownExtender control. The request is sent by an image element( the dropdown image ).

Initially, the img element's src is set to null, thus the browser sends a request to currentRootFolder/null for it.

When you move the mouse over it, its src is changed to a valid image ( by default, a triangle ).

When a postback happens, the img element is reinitialized to null again.

That's why you will see a 404 response.

It's not encouraged to change the source code/internal behavior of the DropDownExtender to get rid of it, because inappropriate change may bring a bigger trouble.

How do you enable logging on your application? It will be better if you can apply a filter to it. For instance, don't log the one whose request contain a url like "folderName/null"

Hope this helps.

Hi Raymond

What you described is the function of the DropDownExtender but I believe the 404 response can be avoided rather than being a "normal" occurence. I have posted the issue on codeplex (http://www.codeplex.com/AtlasControlToolkit/WorkItem/View.aspx?WorkItemId=11521) and hope this may help those who encountered the same problem.
