Question

A strange problem.
On my page i have a placeholder where I create a repeater on run time.
In ItemTemplate i have a button that invokes repeater_ItemCommand event.

I put a breakpoint on first line of repeater_ItemCommand event, when the button is triggered the event is invoked as planned, but after RebindRepeaters() is finished, when i click on the button again repeater_ItemCommand event is not invoked!
Only if i click on the button one again it invokes, in other scenarios(this is simple version of my page, in original page i have updatepanel that complex everything) it never invokes!

My aspx code:

<form id="form1" runat="server">
    <div id="talk">          
          <asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>
    </div>                                                 

My Code-behind:

protected void Page_Init(object sender, EventArgs e)
{
    RebindRepeaters();
}

void RebindRepeaters()
{
    PlaceHolder1.Controls.Clear();     
    CreateRepeater(PlaceHolder1);
} 

void CreateRepeater(Control container)
{
    Repeater repeater1 = new Repeater();       

    repeater1.ItemCommand += new RepeaterCommandEventHandler(repeater_ItemCommand);
    repeater1.ItemTemplate = Page.LoadTemplate("CommentsTemplate.ascx");
    container.Controls.Add(repeater1);

    repeater1.DataSource = Comment.GetCommentsP(8, 0);
    repeater1.DataBind();
}

void repeater_ItemCommand(object sender, RepeaterCommandEventArgs e)
{
    switch (e.CommandName)
    {                          
        case "Edit":               
            RebindRepeaters();
            break;
    }
}

The CommentsTemplate.ascx:

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="CommentsTemplate.ascx.cs" Inherits="CommentsTemplate" %>

 <ul>
    <li>
      <div class="show">

         <div class="c">                  
             <asp:LinkButton ID="lbtnTitle" runat="server"  Text='<%#Eval("EncodedTitle")%>' 
                 CausesValidation="false"  CommandName="VoteUp" OnClientClick="viewHide(this);return false;"   CommandArgument='<%#Eval("ID")%>'></asp:LinkButton>                              
             <p class="d"><%#Eval("AddedBy")%>,<%#Eval("AddedDate")%></p>
             <div class="CommentBody"><%# Eval("EncodedBody") %>
             </div>
         </div>
             <div class="userpanel">


               <asp:Panel runat="server" ID="panAdmin" Visible='<%# UserCanEdit %>' style="float:left;">
                 <asp:ImageButton runat="server" ID="btnSelect" CommandName="Edit" CommandArgument='<%# Eval("ID") %>'
                     CausesValidation="false" AlternateText="Edit comment" ImageUrl="~/Images/Edit.gif"  />                
                 <asp:ImageButton runat="server" ID="btnDelete" CommandName="Delete" CommandArgument='<%# Eval("ID") %>'
                   CausesValidation="false" AlternateText="Delete comment" ImageUrl="~/Images/Delete.gif"
                   OnClientClick="if (confirm('Are you sure you want to delete this comment?') == false) return false;" />
               </asp:Panel>  

             </div>                                                        
      </div>                
            </li>
 </ul>  

If you need more info just ask.

Could you try overidding createChildcontrols and add the RebindRepeaters call there instead of in Page_Init? And make sure to give your repeater an explicit ID:

Repeater repeater1 = new Repeater(); 
repeater1.ID = "repeater1";

Without an id the asp.net event handling won’t know where the event was called from.
