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 Accordion with Paging

hi there; using asp.net 2.0 (vb) i've just created a page that, in the page load event, retreives a number of records from the database.

as each record is read into a dataset, a new accordon panel is created. the panel header displays the fldName and the panel content displays the fldContent from the table.

this all works great. the issue i'm having is that it currently displays all the records (approx 200) and i only want 10 records displayed at a time.

my question is, is there somehow a way to implement paging? i found the following article:

http://rolf-cerff.de/blogs/dotnet/archive/2007/03/08/ajax-control-toolkit-paging-with-databound-accordion-control.aspx

but i'm not familiar enough with C# to understand.

also, any idea if paging for the accordion is in the works?

thanks all.

You can use a paged data source...

Basically, create a datatable from your recordset, and then...
Dim pds As New PagedDataSource
pds.DataSource = (whatever then dataset is called).Tables(0).DefaultView
pds.AllowPaging = True
pds.PageSize = 10
pds.CurrentPageIndex = curpage (passed into the databind sub, optional value that = 0 at first)
CurrentPage (see below) = pds.CurrentPageIndex + 1

What I do is to create a viewstate item called CurrentPage to keep track of the pages...
Public Property CurrentPage() As Integer
Get
Dim o As Object = Me.ViewState.Item("_CurrentPage")
If o Is Nothing Then
Return 0
Else
Return o
End If
End Get
Set(ByVal value As Integer)
Me.ViewState.Item("_CurrentPage") = value
End Set
End Property

You can then have linkbuttons to guide through pages... Just rebind using your sub and pass in CurrentPage as the curpage to advance or CurrentPage - 1 to go back.

Dyanimc TextBoxWatermark in GridView Pager Template

I have a textbox in my gridview pager template to allow the user to enter a page number to jump to. I would like the watermark to read Page X of Y. I tried to set the watermark text on the GridView_DataBound event, but that doesn't work.

My guess is this occurs because most (if not all) AJAX controls render client scripts durning the preload event and the databound event executes long after the preload. Is this correct? Is this by design? Will AJAX controls always render in the preload event?

Is there a workaround I could use to generate thePage X of Y for the watermark via javascript or something?

Thank you for your assistance

This should work - have a look at the DataBinding.aspx page in the ToolkitTests directory for an example. If you're still stuck, please post a complete, self-contained sample demonstrating the issue. Thanks!
