Should be able to do that from code.... take out the onclick from aspx and
add the following in your code-behind (this is in c#)

ibtnExpandResource.Attributes.Add("onclick", "javascript:OnPlusClick(this);");

In Page_Load, do this:
ibtnExpandResource.Attributes.Add("onclick","Javascript:
OnPlusClick(this);")

The ASP:Image tag is in a templatecolumn within a datagrid!

I don't think this would work???

Any Ideas!

Thanks

This looks fine. There is no need to use Attributes in code behind since
there is no server-side onclick event for Image control. What problem are
you experiencing?

Oh. I think you will need to do this in PreRender. Unless ... to Eliyahu's
point, shouldn't it work just by setting the attribute in the asp: tag? I
don't have time to test it myself right now, but did you test before
posting? If so, what happened?

Ok, I found the time to test it (I was curious). This works fine:

<script type=text/javascript>
function test(obj)
{
alert(obj.parentElement.parentElement.rowIndex)
}
</script>
....
<asp:TemplateColumn>
<ItemTemplate>
<IMG src="../Images/Completed.gif" onclick="test(this)">
</ItemTemplate>
</asp:TemplateColumn>

Heh. This isn't really testing what you were asking about (i just noticed).
Let me try again ... yes it still works:

<asp:TemplateColumn>
<ItemTemplate>
<asp:Image id="Image1" runat="server"
ImageUrl="../Images/Completed.gif"
onclick="test(this)"></asp:Image>
</ItemTemplate>
</asp:TemplateColumn>

The word "onclick" has the red squiggly underline, but it can safely be
ignored.
