I have a user control that contains a repeater. We have added some paging and sorting into the user control and it all works well.
What I need now is a nice way to catch the OnItemDataBound event of the inner repeater and then bubble it up to be accessible directly from the user control from within the page.
We have tried catching it and then declaring it in the user control but it just won't work.
how do i fire the itemdatabound event for a repeater control which is nested inside a another repeater control
code is in vb.net
I tried to generate Button control on the fly repeater's ItemDataBound event.

However, when I am about to capture the gridview's itemcommand event, it seems like the command doesn't work.
I need to change the mouse pointer style to "HAND" like looking thing when i hover my mouse over accordian control or rather an accordian pane.How can i do that?
View 2 Repliesi have simple repeater control on my page:
<asp:Repeater id="Repeater1" runat="server" DataSourceID="SqlDataSource1">
<ItemTemplate>
<asp:TextBox id="txtBox1" runat="server" Text='<%#Eval("attributename") %>'></TextBox>
<ItemTemplate>
</Repeater>
I'm bounding data to repeater control by using SqlDataSource Control
bounded data is something like this:
attributeid attributename
1 color
2 size
How can I get access to attributeid values in Repeater control's ItemDataBound event handler,
I tried to use DataBinder.GetPropertyValue(container,"attribuetid"), but I can't set container, am I doing right, or maybe I should use another approach.
I have a gridview called gvResults. In the gvResults_RowEditing event I add a row below the one selected. In that new row, which spans all columns, I insert a user-control. There are two buttons and some textboxes in the user control.
My problem is that when I click one of the user-control buttons it never gets to the button event handler, I think because the user control is not recreated on the page postback. How can I have the user-control events fire before the parent page events fire?
I tried using an update panel, but I still get the parent posting back before the user-control events.
I am facing one strange problem,I have a gridview in which the last two columns have checkboxes and on those checkboxes click event I am doing some database operations.I also have one checkbox that is outside the gridview which actually shows or hides some of the gidview columns.This was all working well but now I have shifted that grid to a user control because I have to use it in two pages.The problem now is,When the page first loads and I click the check box or any control in the page that is outside the grid then it works perfectly.But once I click any of the check box within grid view column then its behavior chages, now even if I click the checkbox that is outside the grid then also the checkbox_CheckedChanged event of the checkbox that is whithin gridview is fired.That checkbox event then behaves something like a page_load event that is called for every page load and for every event with in the page after it is called once.
View 3 RepliesUnusual one this - IE7 and IE8 both behaving, but Firefox isn't. So, I suspect that I have done something wrong which I am "getting away with" in IE.....I have a DynamicPopulateExtender (DPE) and two ModalPopupExtenders (MPE). A Javascript function shows the first MPE (a "please wait" message) and then retrieves the DPE. When the DPE finishes retrieving, its populated event fires - that hides the first MPE and shows the second one which holds the results retrieved by the DPE.I know that I could have used built in functionality within the DPE to display the "please wait" message. However that would mean displaying the MPE before populating the DPE. I can't do that because I want to size the MPE depending on what comes back from the DPE.So, this is my Javascript:
[Code]....
As I said, it works fine in IE7 and IE8. In Firefox (and Opera and Safari), the "please wait" appears and then nothing else happens.
I am loading in a user control on page load and events are never firing. The user control loads fine with the correct information. it contains two dropdowns and an
calendar control. The dropdown selection changed event is never fired. I am not sure if there is something wrong while control is being rendered.

I have a AsyncFileUpload control inside a custom Web User Control which is placed on two different pages.
The AsyncFileUpload control works fine on one of the pages the Web Control is placed but on the other it doesn't fire the OnUploadedComplete event.

I have a usercontrol and in that i have a dropdown. i need async postback for dropdown selectedindexchanged event. i set the AutoPostBack=true for dropdown. Eventhough the event is not getting fired.

i am using VWD(visual web developer 2008) and DOTNET 3.5
i have a page on which i dynamically add multiple datalist controls on the oninit event of my page , on postabck i again add all these datalist controls to the page on oninit event
the template for all the datalist controls is defined using the ITemplate interface, the template defined for each datalist control contains a button which has a event handler attached to onclick event.
the problem is first time i click the button on postback i add the multiple datalist controls , the event gets fired which modifies the datatable i am using to generate my datalist controls and the datalist controls with the modified data show on the page but the second time a user clicks the button inside datalist the event does not get fired.
While I am using a "Telerik" control here it shouldn't be any different I guess;
[code]....
What happens is that the control is created and rendered;
When I change value in the Combo box a Post-Back happens.
HOWEVER, the event RadComboBoxSelectedIndexChanged does not fire. Also when I am back at the page the new value is not saved; Obviously, i recreate the control every time. If I don't I get a ViewState error. Seems to me that there some ViewState management problem, but I cannot identify it...
I have a control which has an ImageButton which is tied to an OnClick event... Upon clicking this control, a postback is performed and the event handler is not called. AutoEventWireup is set to true, and I've double checked spelling etc.... We haven't touched this control in over a year and it has been working fine until a couple of weeks ago.
We have made changes to controls which load this control... so I'm wondering, what kind of changes could we have made to stop this event handler from being called? There is quite a bit of Javascript going on, so this could be the culprit too...
I want to fie event calender_dayrender forcefully in dropdownlist_selectedindex .Dont know how to give parameters (sender,e).
View 3 RepliesI'm creating a next/previous function for my repeater using pageddatasource. I added the link button control dynamically in my oninit using the following code.

So I am incrementing the cookie I am using to track the page number and then rebinding the repeater.
Here is the main issue. The first time I click Next, it works, it goes to Page 2 without any problems. When on Page 2, I click Next, it goes back to Page 1. Seems like the Next event is not wiring up properly.

I have two problems with a databound AJAX Accordion. The Accordion looks like this:
[Code]....
The code behind has this subroutine:
[Code]....
[Code]....
The first problem I'm having is that this subroutine is not fired (I have a breakpoint in it) when the LinkButton inside the accordion is clicked. The Page_Load event fires and there is no error message, javascript errors, etc, but nothing else happens.
The second problem is that I'm not sure how to go backwards with the databind. I want to be able to make use of the UpdateMethod in the ObjectDataSource because I also have textboxes inside the accordion. I will have a Save subroutine that can be called but I'm not sure what code to put inside it.
I have a master page containing a ScriptManager control, and a Content Page containing a ScriptManagerProxy Control. Further on the content page I have an UpdatePanel control containing a GridView control and a server side button control. I have registered the button control as a trigger with the UpdatePanel control asynchronously and have set the UpdateMode of the UpdatePanel to "Conditional". I also have a "JumpLoader" control which is outside the UpdatePanel control. I have the following event for Jumploader wired up through Javascript. I am pasting the relevant sections of the code below:
[Code].....
I have a web application that shows a page containing between 6 and 20 UpdatePanels, contained with Custom Web (.ascx) Controls.
You can see an example of such a page here: [URL]
The problem I'm getting is that when the user FIRST clicks any of the radio-buttons on any of the controls in the page, ALL the radio buttons that have an active selection ALSO fire an rb_CheckChanged event (see application log below). On subsequent radio-button clicks, only that RB fires the event (as expected).
This behaviour is having a dramatic impact on performance. The page loads quickly, and a "normal" RB click provides an AJAX update correctly within 1 second. The problematic first RB click, however, takes up to SIX seconds to process, which is unacceptable from a user experience standpoint.
Developed in VS.NET 2008, ASP.NET 3.5. Also I converted the "Web Site" solution to a "Web Application" (pre-compiled) and got the same performance (still too slow). Release builds run only marginally faster than debug builds.
Why would a single RB selection change cause all RB's that have a "selection" set on them to also fire? (The "selection" is determined through database settings every time the control is populated, which is called from within the parent page control's Page_Load function. This selection is determined also at first page load, since all the controls get populated then, so why would the clicking of an RB cause them all to fire an event, and only once? That's what I don't get...)
