Glossary Item Box

Sometimes when you enable AllowAddItem and AllowAutoPostBack, you missed to create WebCombo_AddItem server side event. In this case, an error will occur because AddItem event is called but there is no event to handle this task. In this situation, you should create WebCombo_AddItem server side event.

For example:

C# Copy ImageCopy Code
protected void WebCombo1_AddItem(object sender, ISNet.WebUI.WebCombo.RowEventArgs e
{
   // get cached data from data source control
   DataView view = this.EmployeeDataSource.Select(DataSourceSelectArguments.Empty) as DataView;       

  // update the cached data
  DataTable table = view.Table;
  DataRow newRow = table.NewRow();
  newRow["FirstName"] = e.Row.Value;
  table.Rows.Add(newRow);
}
