Question

Here’s the code from the ascx that has the repeater:

<asp:Repeater ID='ListOfEmails' runat='server' >     <HeaderTemplate><h3>A sub-header:</h3></HeaderTemplate>     <ItemTemplate>         [Some other stuff is here]         <asp:Button ID='removeEmail' runat='server' Text='X' ToolTip='remove' />     </ItemTemplate> </asp:Repeater> 

And in the codebehind for the repeater’s databound and events:

Protected Sub ListOfEmails_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles ListOfEmails.ItemDataBound     If (e.Item.ItemType = ListItemType.Item) Or (e.Item.ItemType = ListItemType.AlternatingItem) Then         Dim removeEmail As Button = CType(e.Item.FindControl('removeEmail'), Button)         removeEmail.CommandArgument = e.Item.ItemIndex.ToString()          AddHandler removeEmail.Click, AddressOf removeEmail_Click         AddHandler removeEmail.Command, AddressOf removeEmail_Command     End If End Sub  Sub removeEmail_Click(ByVal sender As Object, ByVal e As System.EventArgs)     Response.Write('<h1>click</h1>') End Sub  Sub removeEmail_Command(ByVal sender As Object, ByVal e As CommandEventArgs)     Response.Write('<h1>command</h1>') End Sub 

Neither the click or command is getting called, what am I doing wrong?

Answer 1

Controls nested inside of Repeaters do not intercept events. Instead you need to bind to the Repeater.ItemCommand Event.

ItemCommand contains RepeaterCommandEventArgs which has two important fields:

• CommandName
• CommandArgument

So, a trivial example:

void rptr_ItemDataBound(object sender, RepeaterItemEventArgs e) {     if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)     {         // Stuff to databind         Button myButton = (Button)e.Item.FindControl('myButton');          myButton.CommandName = 'Add';         myButton.CommandArgument = 'Some Identifying Argument';     } }  void rptr_ItemCommand(object source, RepeaterCommandEventArgs e) {     if (e.CommandName == 'Add')     {         // Do your event     } }
