I can I get the current record from the underlying datasource when the selected index of a combo box in the cell of that row chanages.
I am trying to use the TableControlCurrentCellShowingDropDown event, but can't seem to get to the Record.

Hi James,
Thanks for being patience.
Please try using e.TableControl.Table.CurrentRecord property in the TableControlCurrentCellShowingDropdown event. The following is the code snippet
>>>>>>>>>>>> Code Snippet <<<<<<<<<<<<<
// TableControlCurrentCellShowingDropdown event
GridComboBoxCellRenderer cr = e.TableControl.CurrentCell.Renderer as GridComboBoxCellRenderer;
if (e.TableControl.Table.CurrentElement.IsRecord)
{
Record currentRecord = e.TableControl.Table.CurrentRecord as Record;
object obj = currentRecord.GetValue("parentID");
===
}

Have a nice day.
Best regards,

This event is being raised even before the combo box opens or the selected index changes..
I am only interested in the selected index change property, if there is one.
I want to change other parts of the record when the selected index of the cobo box changes. I also want to be able to reset the combo box to its previous value when validate fails.

Hi James,
Thank you for being patience.
This can be achieved by handling the TableControlCurrentCellCloseDropDown event. In the event the SelectedValue / SelectedIndex property can be handled to retrieve the selected value from the comboBox.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
// TableControlCurrentCellCloseDropDown
GridComboBoxCellRenderer cr = e.TableControl.CurrentCell.Renderer as GridComboBoxCellRenderer;
object value = cr.ListBoxPart.SelectedValue; // SelectedItem;
if (e.TableControl.Table.CurrentElement.IsRecord)
{
Record currentRecord = e.TableControl.Table.CurrentRecord as Record;
switch (value)
{
case "One":
currentRecord.SetValue("Column1", 3);
break;

}
}

Please refer to the following KB article for different validation techniques.
