Dynamic Gridview

Hi!

I've got a quetion on dynamic gridview load. In my atlas website project i have a gridview that i want to load dynamically. That is, I don't want to load all the data in my datasource because the web page could charge slowly; so, i want to charge only part of the data as fast as possible then, load the other paghes when the user asks for it. How can I do it? Am I to write a C# class in order to manage the load?

Thanks

hi,

it depends on what level do u want to do this ,at what level is it loading slowly.....1)from the dataserver to the dataobject or 2)the control to the current instance of the page...?

it downloads slowly from the dataserver to the dataobject

where is your select query placed?may be in datasource...... place it in a stored procedure as stored procedures are precompiled..... & call the stored procedure....also set EnablePaging to true of the gridview.

My query select is placed in my datasource and my EnablePaging is set to true

dropshadowextender visible when its targetcontrol is not

Hi

I have read thsi post which addresses this problem

http://forums.asp.net/thread/1325356.aspx

I have downloaded the latest version of the toolkit and my dropshadowextender is visible when the control it's shadowing is not visible.

How can i modify the javsacript in DropShadowBehavior.js in my current dll. Presumably its embedded.

Thanks very much

Hi Andrea,

You can just edit the *.js files. You have torebuild the project for the changes to take effect though.

Thanks,

The fix mentioned in the above thread is known to work under at least some circumstances. Could you please post a simple sample demonstrating how it doesn't work in your scenario? That'll help us make a fix. Thanks.
thanks very much

DropShadowExtender problem

Hi

I am trying to place a DropShadowExtender for an asp:panel which is bound with HoverMenuExtender. So if the user hovers over a link, the panel will show up and drops a shadow. But the problem is the shadow is always showing up and when a user hovers away from the link the hovermenu dissapers but shadow remains there. Anyone knows a solution?

Thanks.

Hi Zeeshan,

I would recommend adding anotherPaneland have the DropShadowExtender point to the old one and theHoverMenuExtender point to the new one. If your currentPanel has the IDMyPanel, then you would want something that looked like this:

<asp:Panel id="WrapperPanel" runat="server" ... >
<asp:Panel id="MyPanel" runat="server" ... >
...
</asp:Panel>
</asp:Panel>
<atlasToolkit:DropShadowExtender ID="dse" runat="server">
<atlasToolkit:DropShadowProperties TargetControlID="MyPanel" ... />
</atlasToolkit:DropShadowExtender>
<atlasToolkit:HoverMenuExtender ID="hme" runat="Server">
<atlasToolkit:HoverMenuProperties PopupControlID="WrapperPanel" ... />
</atlasToolkit:HoverMenuExtender>

Thanks,
Ted

Thank you so much Ted. I was wondering if I can have fade in/out effect on my HoverMenuExtender. I tried doing it with scripts on my page but it doesn't work as the panel is under control of the extender so the effect doesn't show up. Anyone knows any other way around?

Thanks

Hi Zeeshan,

Right now the only way to change the visual effects for any of the controls is to change the script. This is even more complicated forHoverMenuBehavior.js because you'll notice that it uses theSys.UI.HoverBehavior andSys.UI.PopupBehavior classes defined by "Atlas".

Thanks,
Ted

dropdownlist and server side validation control

Hi

I have a dropdownlist and it has a required field validator inside an updatepanel. Validation is done on server side and client side is disabled.
I have other controls with required field validations (server side only) and is NOT inside update panel.

The issue is when i select an item in dropdownlist it does a partial postback and validation is performed and the error message next to the dropdownlist will disappear. But for the other controls though the user fills in the data, the error message will only disappear on full postback on submit button click. This might be confusing for the user.

How can i make it work to have a standard error message display ONLY ON submit button click for all controls (including the partial postback controls inside updatepanel) ?

Is there any way i can do other than,
1. validation summary on top/bottom of the page.
2. Taking validation control outside update panel. If i have more than 10 controls, then i need to add more than 10 update panel and html table structures etc. etc.

Any ideas?

Thanks

DropDownExtender breaks table in Firefox

Hi!

I'm using the DropDownExtender over a tablerow.
It's working ok in IE7 but not in Firefox.

All columns get merged into the first one when the DropDownExtender is created.
I'm using the latest release (Feb 01)
Here's an example
