My data source was redefined by myself, now every time I click "Delete", an error will be reported
"GridView" GridView1 "fired the unhandled event" RowDeleting "
Same with "choice"
Is to rebind the data, but how to bind it

private void dgShow_DeleteCommand (object source, System.Web.UI.WebControls.DataGridCommandEventArgs e)
{
if (dgShow.Items.Count == 1)
{
if (dgShow.CurrentPageIndex! = 0)
dgShow.CurrentPageIndex = dgShow.CurrentPageIndex-1;
}
string strSql = "delete from tbStudentinfo where studentid =" + e.Item.Cells [0] .Text + "";
ExecuteSql (strSql);
BindData ();

} This is the deleted full code

If it is deleted using Button, here is the code for Button deletion
private void btnDelete_Click (object sender, System.EventArgs e)
{
foreach (DataGridItem dgi in dgShow.Items)
{
CheckBox cb = (CheckBox) dgi.FindControl ("cbSelect");
if (cb.Checked)
{
// The following delete operation is performed
int nID = int.Parse (dgi.Cells [0] .Text);
string strSql = "delete from tbStudentinfo where studentid =" + nID;
ExecuteSql (strSql);
}
}
dgShow.CurrentPageIndex = 0;
BindData ();
}
