Capture CheckBox Click Event

[news.microsoft.com]

I have a datagrid with a checkbox column. The column is bound to adatabase,
and I have no problem capturing a click event on the checkbox using the
OnCheckChanged event handler.

Here is a sample of the html used to build the column:
<asp:TemplateColumn HeaderText="Crew Chief?">
<HeaderStyle HorizontalAlign="Center" Width="40px"
VerticalAlign="Middle"></HeaderStyle>
<ItemStyle HorizontalAlign="Center"></ItemStyle>
<ItemTemplate>
<asp:checkbox id=chkChief runat="server"
cssclass="FormFieldText2"
OnCheckedChanged="cbChief_Clicked"
COMMANDARGUMENT='<%#Container.DataItem("SAN") %>'
AutoPostBack=True Checked='<%#
bSetCheckValue(Container.DataItem("IsChief"))%>'>
</asp:checkbox>
</ItemTemplate>
</asp:TemplateColumn>

The event handler function fires and I get a reference to the checkbox
object that was clicked.

The problem is that I am trying to get a reference to the row that the
checkbox was clicked in to retrieve the datakey value. I know I could loop
through the entire dataitem list and find the match, but what I was trying
to do was pass the datakey value for the row as a command arguement, so that
I can use the datakey value directly in the event handler.

Has anyone been able to make this work?

Thanks,
Marc.

Here is the answer to my post. Thanks to Michael.

protected void cbChief_Clicked(object sender, EventArgs e) {

string _val = ((CheckBox)sender).Attributes["COMMANDARGUMENT"]; // Here we
received value in the attribute of checkbox.

foreach(DatagridItem dr in Datagring.Items)

{

// your code.

}

}
