Question

I’ve got a LinkButton control in a user control like this (Accordion is from the AJAX Control Toolkit):

<cc1:Accordion runat='server'>     <Panes></Panes>     <HeaderTemplate></HeaderTemplate>     <ContentTemplate>         <asp:TextBox Text='<%# Bind('Title') %>' runat='server'></asp:TextBox>         <asp:LinkButton Text='Update' CommandArgument='<%# Container.DataItem %>' CommandName='ItemUpdate' OnCommand='LinkButton_Command' runat='server'></asp:LinkButton>     </ContentTemplate> </cc1:Accordion> 

The accordion is bound in Page_Load:

protected void Page_Load(object sender, EventArgs e) {     Accordion1.DataSource = GetACollection();     Accordion1.DataBind(); } 

But in the command event handler, no matter what I do, the arguments are always strings:

protected void LinkButton_Command(object sender, CommandEventArgs e) {       // sender is alway a string (the Text of the clicked button)       // e is always a string property of the Container.DataItem object } 

The strings are coming from the right objects (the button and the bound DataItem, respectively), but I need the objects themselves (the DataItem particularly).

What’s going on?

Answer 1

Wouldn’t that be expected behavior..

Property Value Type: System..::.String
An optional argument passed to the
Command event handler along with the
associated CommandName property. The
default value is String..::.Empty.
