Question

I have an ImageButton being build inside of radgridview columnn. It is defined as follows.

<asp:ImageButton ID="ImageButton_DeleteRun" ImageUrl="~/Assets/Images/Misc/delete.png"
runat="server" OnClick="QueryDelete" CommandName="QueryDelete" 
CommandArgument='<%# DataBinder.Eval(Container,"DataItem.QueryGuid") %>'
Width="10" Height="10" />

It loads properly. When I click on it, I expect to hit the following codebehind method:

protected void QueryDelete(object sender, EventArgs e)
{
/* A bunch of code*/
}

It never gets there. What is more fustrating is that if I replace the ImageButton with

<asp:LinkButton ID="ImageButton_DeleteRun" Text="X"
runat="server" OnClick="QueryDelete" CommandName="QueryDelete" 
CommandArgument='<%# DataBinder.Eval(Container,"DataItem.QueryGuid") %>'/>

It works perfectly.
Is there something wrong with ImageButton? Am I missing something?

EDIT – New info

Basically when the image button is rendered, there is no href.

Weird–

<input type="image" style="height: 10px; width: 10px; border-width: 0px;" src="../Assets/Images/Misc/delete.jpg"
id="ctl00_ctl00_ctl00_AllContent_MainContent_MainContent_controlPanelQueryHistory_saved_RadGridQueryHistory_ctl00_ctl04_ImageButton1"
name="ctl00$ctl00$ctl00$AllContent$MainContent$MainContent$controlPanelQueryHistory_saved$RadGridQueryHistory$ctl00$ctl04$ImageButton1"/>

<a
href="javascript:__doPostBack('ctl00$ctl00$ctl00$AllContent$MainContent$MainContent$controlPanelQueryHistory_saved$RadGridQueryHistory$ctl00$ctl04$ImageButton_DeleteRun','')"
id="ctl00_ctl00_ctl00_AllContent_MainContent_MainContent_controlPanelQueryHistory_saved_RadGridQueryHistory_ctl00_ctl04_ImageButton_DeleteRun">delete</a>

As a work around you could try wrapping an image within a LinkButton.

<asp:LinkButton ID="ImageButton_DeleteRun" Text="X"
runat="server" OnClick="QueryDelete" CommandName="QueryDelete" 
CommandArgument='<%# DataBinder.Eval(Container,"DataItem.QueryGuid") %>'>
    <img src="~/Assets/Images/Misc/delete.png" /> 
</asp:LinkButton>
