Wrong event handler firing in DataGrid

[arlie_maija]

Hey -

I'm writing a control that contains a DataGrid, and I'm unable to get
the update event to fire. When I click the update link, the edit event
fires.

heres the details...

my control overrides CreateChildControls and dynamically creates the
DataGrid, creates an EditCommandColumn which it adds to the
DataGrid.Columns, and then adds several BoundColumns. I then create a
dummy dataset and bind it to the DataGrid. I then create and set an
EditCommandEventHandler for the EditCommand, CancelCommand, and
UpdateCommand. finally I add the datagrid to the Control array.
...
in Render I tell the DataGrid to render.

When I run this, It looks right, and the edit and cancel buttons work
fine, but the update link fires the Edit event.

heres my code... any help on whats going on here would be really
appreciated.

private DataGrid dataGrid1;
private Label lblMsg;
private string messageText = "";
private DataSet myDataSet;

private string MessageText
{
get
{
return messageText;
}
set
{
messageText = value;
}
}


protected override void Render(HtmlTextWriter output)
{
// Start Main Table
output.AddAttribute("width", "100%");
output.RenderBeginTag(HtmlTextWriterTag.Table);

// Write the Message Text
output.RenderBeginTag(HtmlTextWriterTag.Thead);
output.RenderBeginTag(HtmlTextWriterTag.Tr);
output.AddAttribute("class", "message");
output.AddAttribute("colSpan", "2");
output.RenderBeginTag(HtmlTextWriterTag.Th);
output.Write(MessageText);
output.RenderEndTag();
output.RenderEndTag();
output.RenderEndTag();

// Start Main table body
output.RenderBeginTag(HtmlTextWriterTag.Tbody);
output.RenderBeginTag(HtmlTextWriterTag.Tr);

// Write the DataGrid column
output.AddAttribute("align", "center");
output.AddAttribute("valign", "top");
output.RenderBeginTag(HtmlTextWriterTag.Td);
dataGrid1.RenderControl(output);
output.RenderEndTag();

output.RenderEndTag(); // row
output.RenderEndTag(); // main table body
output.RenderEndTag(); // main table
}
public override ControlCollection Controls
{
get
{
EnsureChildControls();
return base.Controls;
}
}
