I have a datalist that contains an imagebutton control. I've added an AJAX confirm button extender to this imagebutton, but I want to dynamically change the confirm text depending on the datalist item.
My datalist code is:-

Code:

<asp:datalist ID="dlst_userlist" runat="server" OnItemDataBound="dlst_userlist_ondatabind" OnEditCommand="dlst_remove_user" CssClass="registerform">
<ItemTemplate>
<tr><td valign="middle"><asp:label ID="lbl_username" runat="server" cssclass="dblue8" Text='<%#Eval("full_name") %>' /></td><td valign="middle"><asp:ImageButton ID="img_remove_user" ImageUrl="link_doc_remove1.gif" CommandName="Edit" CommandArgument='<%#Eval("linkref") %>' runat="server" /></td></tr>
<ajaxtoolkit:ConfirmButtonExtender ID="conf_remove_user" runat="server" ConfirmText='Are you sure you wish to remove <%#Eval("full_name") %> from this task?' TargetControlID="img_remove_user" />
</ItemTemplate>
</asp:datalist>

I tried creating an instance of the extender in my onitemdatabound routine, like this:-

Code:

e.Item.FindControl("conf_remove_user").confirmtext = "Are you sure you want to remove " & e.Item.DataItem("full_name") & " from this task?"

but it says confirmtext is not a member of 'System.Web.UI.Control'. I can't create an instance of the object type within the routine, because it doesn't seem I can create an ajaxtoolkit object, such as Dim username as confirmbuttonextender, for example.

At the moment if you click the button the confirm text is "Are you sure you wish to remove <%#Eval("full_name") %> from this task?"

I want it to say "Are you sure you wish to remove Joe Bloggs from this task?"

Any ideas how to dynamically change this text?

Thanks

Try creating an instance like so:

Code:

Dim btnExtender As AjaxControlToolkit.ConfirmButtonExtender
btnExtender = CType(e.Item.FindControl("conf_remove_user"), AjaxControlToolkit.ConfirmButtonExtender)

I haven't done this before, so not sure. Let me know how it goes

Perfect. It was the ajaxcontroltoolkit.confirmbuttonextender that I didn't know I could do.
Solution:

Code:

Dim btn_extender as AjaxControlToolkit.ConfirmButtonExtender = e.item.findcontrol("conf_remove_user")
btn_extender.ConfirmText = "Are you sure you want to remove " & e.Item.DataItem("full_name") & " from this task?"

Thanks J...
