OnClick event question

[EMW]

My datagrid has four template columns in which an ImageButton is created.
I use the following to add the OnClick event to the button.

img.Attributes.Add("OnClick", "AllButtons_Click")

The AllButtons_Click sub is:

Sub AllButtons_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim Btn As System.Web.UI.WebControls.Button = sender
Response.Write("You clicked button " & Btn.CommandArgument)
End Sub

But this sub is not run, I get an error telling me AllButtons_Click is not
defined.
Can anyone help me with this?

thanks,
Eric

You are trying to run a server side function on the client. Web pages don't
work that way.

You need to add a 'onlick' attribute, and have the function be a client side
function written in client side javascript.

If you want to add a server side event handler, then you have to use the
AddHandler statement - as it has nothing to do with the attributes rendered
on the client.

You just can't mix client side and server side events like this.

Instead of adding it as an attribute, who don't you just do
OnClick="AllButtons_Click"
Note that for an ImageButton click event you should pass
System.Web.UI.ImageClickEventArgs e instead of System.EventArgs

Attributes.add is for adding to the html element. This has nothing to
do with the .net event model. You will have to add an event handler
to handle the click event.
