I have a checkbox under gridview. I want to call the ID of the checkbox from code-behind but I am getting error as
Object reference not set to an instance of an object.
see the below code.
protected void btnUpdate_Click(object sender, EventArgs e)
{
CheckBox chkSelect = sender as CheckBox;
GridView grd = chkSelect.Parent as GridView;
if (chkSelect.Checked == true)
{
}
else
{
Response.Write("<script>alert('Please select checkbox to update');</script>");
}
}
Go to the complete details ...
