I cannot make the link buttons fire ItemCommand from
repeater control.
Here is the code:
<asp:repeater id=rptLetters runat="server">
<itemtemplate >
<asp:linkbutt on id="lnkLetter"
runat="server" commandname="Fi lter"
CommandArgument ='<%#
DataBinder.Eval (Container, "DataItem.Lette r")%>'>
<%# DataBinder.Eval
(Container, "DataItem.Lette r")%>
</asp:linkbutton>
</itemtemplate>
</asp:repeater>
In code-behind I've got:
this.rptLetters .ItemCommand += new
System.Web.UI.W ebControls.Repe aterCommandEven tHandler
(this.OnLetterC licked);
and
protected void OnLetterClicked (object source,
System.Web.UI.W ebControls.Repe aterCommandEven tArgs e)
{
if (e.CommandName == "Filter")
{
letterFilter = (string)
e.CommandArgume nt;
PopulateGrid();
}
}
and it is does not fire the click event!
However, if I replace link button with regular buttons
<asp:repeater id=rptLetters runat="server">
<itemtemplate >
<asp:button id="lnkLetter" runat="server"
commandname="Fi lter"
CommandArgument ='<%#
DataBinder.Eval (Container, "DataItem.Lette r")%>'
Text='<%# DataBinder.Eval
(Container, "DataItem.Lette r")%>' />
</itemtemplate>
</asp:repeater>
exactly the the same code works fine.
I am using 1.0.3705 framework.
Is this a bug?
Thanks,

Hi Stan,
Based on my research and experience, the following information is useful to
you. Please refer to it carefully.
DataList.ItemCo mmand Event http://msdn.microsoft.com/library/de...us/cpref/html/
frlrfsystemwebu iwebcontrolsdat alistclassitemc ommandtopic.asp
"...
The ItemCommand event is raised when any button is clicked in the DataList
control and is commonly used when you have a button control with a custom
CommandName value.
...
The following example demonstrates how to specify and code a handler for
the ItemCommand event to select an item from the DataList control.
...
<ItemTemplate >
<asp:LinkButt on id="SelectButto n"
Text="Select"
CommandName="Se lect"
runat="server"/>
Item <%# DataBinder.Eval (Container.Data Item, "Item") %>
</ItemTemplate>
..."
If I have misunderstood your concern, please feel free to let me know.

Since this is in a data repeater the code fires the ItemCommand for the data
repeater instead of the LinkButton. This sounds strange but really works
out becuase sometime you can get away without sending any parameters, if the
data you need is in on DataRepeater Item.
To see if this is happening create an event handler for the Repeater control
and put a Messagebox.Show as the only line of code. The everytime you click
the link the message should popup. You can even sent a breakpoint on the
MessageBox.Show and view what data you can access from the datarepeater
using the e.Item object. I have used this numerous times, but the first
time it was very frustrating learning how to extract data from the
datarepeater. Feel free to send me any more questions you might have.

Well I'm trying to catch and act upon a button event that is placed within

working. What I've seen out there to explain how to do this is way
complicated and assumes a familiarity with dot net that I don't have yet.
I'll get it eventually but this is where I'll get it. Here's my code.
First part is the user control and second is the code behind page

Hello.
I am having problems with the repeater webform control. Inside the

user can choose a different date on each of the items in the repeater.
I also have buttons in the <ItemTemplate> section.
The buttons' click event is catched by the repeater's ItemCommand event
and they are handled, but Calendar's SelectionChanged event is not

Assume you want to dynamically add one to many link button controls to a web

execute code. As the link buttons are created at run time and the number may
vary, we can't statically tie to the event to a control. I'm assuming I
need to dynamically add event handlers at run time, and that one method
could act as the event handler, with unique event args being created for...

I thought about doing this with a plain Table server control, but the
problem is that this control does not provide enough events for us to
identify the row in which the button is clicked.
