I have a grid, I want to delete a row.
The relevant code is something like
private void dGridErrorLog_DeleteCommand(object source,
System.Web.UI.WebControls.DataGridCommandEventArgs e)
{
// delete the row
nxCmdDeleteErrorLogItem.Parameters["@LogID"].Value =
dGridErrorLog.DataKeys[e.Item.ItemIndex];
nxConnection.Open();
nxCmdDeleteErrorLogItem.ExecuteNonQuery();
nxConnection.Close();
// rebind the grid:
nxConnection.Open();
nxDataAdapterErrorLog.Fill(nxDataAdapterErrorLog_D ataSet, "errorlog");
dGridErrorLog.DataSource = nxDataAdapterErrorLog_DataSet;
dGridErrorLog.DataMember = "errorlog";
dGridErrorLog.DataBind();
nxConnection.Close();
}
The grid has four rows, which I can see return values for e.Item.ItemIndex
of 0, 1, 2, 3 depending on which row I click on. But calculating
dGridErrorLog.DataKeys[e.Item.ItemIndex];
gives me errors like
<<
