Problem with OnItemCommand event and Loadtemplate

G

Guest

Hi all,
in my previous post I've wrong typed some tems.. this is the corrected post.

in a aspx page I have a repeater like this:
<asp:repeater id=repeaterResults runat="server"
OnItemCommand="RepeaterResult_Event">
<HeaderTemplate>
<table width="515" border="0" cellpadding="3" cellspacing="0">
</HeaderTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
<SeparatorTemplate>
<tr><td colspan="4"><hr></td></tr>
</SeparatorTemplate>
</asp:repeater>

in the code behind file I dinamically load the Itemtemplate with this code:

repeaterResults.DataSource = objPds;
string templateName = "templates/BSResultTextTemplate.ascx";
repeaterResults.ItemTemplate = Page.LoadTemplate(templateName);
repeaterResults.DataBind();

Always in the same code behind file, I've defined the Method specified in
the OnItemCommand property of repeater:

public void RepeaterResult_Event(object sender, RepeaterCommandEventArgs e)
{
string s = " SSS ";
}

below you can see the content of BSResultTextTemplate.ascx :
<tr>
<td class="nerotesti" width="155"><asp:LinkButton id="CmdVisualizzaReperto"
runat="server" CommandName="ItemCommand" CommandArgument=<%#
DataBinder.Eval(Container,"DataItem.ID") %> ><%#
DataBinder.Eval(Container,"DataItem.ID") %></asp:LinkButton></td>
<td class="nerotesti" width="160"><%#
DataBinder.Eval(Container,"DataItem.Culture") %></td>
<td class="nerotesti" width="160"><%#
DataBinder.Eval(Container,"DataItem.Subject") %></td>
<td class="nerotesti" width="60"> </td>
</tr>

Now the problem.... the template is loaded successfully but when I click on
one of the linkbutton generated, the method RepeaterResult_Event is not
fired...
on the other side if I insert the code of template directly in the repeater
definitition and don't load an external template when I click on one of the
linkbutton generated all work fine and the method RepeaterResult_Event is
invoked.

Please have anyone a solution for this?

Thank you.
Antonio.

Thank you Vadivel for your answer but it didn't worked,
as you told me I've inserted this line of code inside InitializeComponent:
this.repeaterResults.ItemCommand += new
System.Web.UI.WebControls.RepeaterCommandEventHandler(this.RepeaterResult_Event);

and I've removed the OnItemCommand property from the aspx file

where is my mistake?

Thank you.
Antonio.

I didn't receive any error, simply the event is not fired... now i've worked
to create a new page with only the essential to reproduce the behaviour:

What i understood from your code is
your should not specify ItemCommand event in aspx file
it should be in your code-behind file.

Create a reference variable for your repeater (repeaterResults) in your cs
file, and go to InitializeComponent method and add ItemCommand event for
this control. It should work.

Do post if you've more problem.

What is the error you're getting?
Can you post the code..
I think that is the lesser way to solve the problem :)

did you ever figure this out?

I'm having the same issue. The problem isn't with the reference in the aspx OnItemCommand or in the Init method in the code behind.

Example

foo.aspx
<asp:Repeater id=rptFoo runat=server />

itemTemplate.ascx
<ItemTemplate>
<asp:LinkButton id=lbFoo CommandName="click me" CommandArgument="1" Text="button click" />
</ItemTemplate>


If I were to take the contents of itemTemplate.ascx and place them on the repeater on foo.aspx, the events for the repeater fire as expected. The problem arises when I rip out the ItemTemplate and put it either in a custom class which inherits the ITemplate interface or in a user control.
