combobox datasource

dotnet windows forms databinding:

Hi

I have a combobox binded to a Datatable
something like

combo.DataSource = dt.DefaultView;
combo.DisplayMember = "descField";
combo.ValueMember = "valueField";

it works fine.
Now if I update the datatable I want the combo to reflect those changes.

I'm trying to rebind the combo doing the same 3 lines but it doesn't work,
(the second time the is run then it does the 1st update)

Any help?
thanks

Hi,
Try binding the selected value of your combobox the column in the datatable
whose changes you want reflected in your control.

ComboBox1.DataBindings.Add _
(New Binding("SelectedValue", myDataSet,
"myDataTable.myDataColumnName"))

Also, when binding a combobox, set the display and value members BEFORE
setting the dataSource. This prevents a firing of the selectedIndex changed
event and gives a performance boost.
