private void dgNumbers_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.EditItem)

DropDownList drpList = (DropDownList)e.Item.FindControl("drpStyleEdit");
drpList.Items.FindByText(((BE.ProgrammeStyle)e.Item.DataItem).Description).Selected = true;

To reduce page bloat, we move view state to session state, rather than store it in hidden fields. This is done by overriding System.Web.UI.Page’s LoadPageStateFromPersistenceMedium() and SavePageStateToPersistenceMedium() methods.
protected override object LoadPageStateFromPersistenceMedium()
{
return Session["__ViewState"];
}
protected override void SavePageStateToPersistenceMedium(object state)
{
Session["__ViewState"] = state;
}
Signature for custom method is
function foo(val, args) {
// test the controls (not sure what val argument is though…?!)
args.IsValid = true | false;
}
Loading several DataTables into a DataSet using DataRelations when there are invalid constraints causes the error message “Failed to enable constraints. One or more rows contain values….”.
Solution is documented here
foreach (DataTable dt in dataset.Tables)
{
if (dt.HasErrors)
{
Console.WriteLine("ERRORS IN : " + dt.TableName);
foreach (DataRow dr in dt.GetErrors())
{
Console.WriteLine(dr.RowError);
}
}
}

This means using a DataList rather [...]
