check checkbox in datagridview is checked or not

Hi,

  if you use TemplateField ASP checkbox then

OnCheckedChanged="chkStatus_OnCheckedChanged"

public void chkStatus_OnCheckedChanged(object sender, EventArgs e)
{
    CheckBox chkStatus = (CheckBox)sender;
    GridViewRow row = (GridViewRow)chkStatus.NamingContainer;

   
    string cid = row.Cells[1].Text;
    bool status = chkStatus.Checked;

}
