How gridview row deleting for nested gridview
<p>I have a a gridview  <code>GridViewTranstoCon</code> inside a main gridview <code>GridViewTtransmittals</code>.
Now for <code>GridViewTranstoCon_RowDeleting</code> I have written the code below, but it is failing.</p>

<pre><code>protected void GridViewTranstoCon_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
    GridView TranstoCon = GridViewTtransmittals.FindControl("GridViewTranstoCon") as GridView;


    OnDeleteTtransmittaltocon(Convert.ToInt32(TranstoCon.DataKeys[e.RowIndex].Value));
        }


private void OnDeleteTtransmittaltocon(int transmittoconid,int transid)
{
    if (DeleteTransmittaltocon != null)
    {
        DeleteTransmittaltocon(this, new tbltranstoconEventArgs { TransmittoconID = transmittoconid, TransID = transid });
      //  DeleteTransmittaltocon(this, new tbltranstoconEventArgs { TransmittoconID = transmittoconid });
    }
}
</code></pre>

<p>And my event handler is like below , I do not know how to add another aegument.</p>

<pre><code>public class tbltransmittalNoEventArgs : EventArgs
{
    public int TransID { get; set; }
}

public class tbltranstoconEventArgs : EventArgs
{
    public int TransmittoconID { get; set; }
    public int TransID { get; set; }

}

public event EventHandler&lt;tbltranstoconEventArgs&gt; DeleteTransmittaltocon;
</code></pre>

<p>What can I do?</p>
