        <asp:GridView ID="GridView1" runat="server" CssClass="EU_DataTable" EmptyDataText="No Data Available.">
            <Columns>
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:CheckBox ID="CheckBox1" runat="server" />  
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>

Answer 1

You can do like this:

In the masterpage codebehind:

public event EventHandler MasterControlClicked;

protected void ImageButton2_Click(object sender, EventArgs e)
{
    OnMasterControlClick(e);

}

protected void OnMasterControlClick(EventArgs e)
{
    if (this.MasterControlClicked != null)
    {
        this.MasterControlClicked(this, e);
    }
}

And in the content page:

protected override void OnInit(EventArgs e)
{
    base.OnInit(e);

    if (this.Master is SiteMaster)
    {
        ((SiteMaster)this.Master).MasterControlClicked += new EventHandler(ContentControlClicked);
    }
}

private void ContentControlClicked(object sender, EventArgs e)
{
    //do whatever you need
}
