You can change the value of other columns when changing value in GridComboBoxColumn of a row using the [CellComboBoxSelectionChanged](https://help.syncfusion.com/cr/windowsforms/Syncfusion.WinForms.DataGrid.SfDataGrid.html#Syncfusion_WinForms_DataGrid_SfDataGrid_CellComboBoxSelectionChanged) event.

#### C#

``` csharp
this.sfDataGrid1.CellComboBoxSelectionChanged += sfDataGrid1_CellComboBoxSelectionChanged;

void sfDataGrid1_CellComboBoxSelectionChanged(object sender, CellComboBoxSelectionChangedEventArgs e)
{
if (e.GridColumn.MappingName == "ShipCityID" && e.SelectedIndex == 0)
(e.Record as OrderInfo).ShipCountry = "Canada";
}
```
#### VB

``` VB
AddHandler Me.sfDataGrid1.CellComboBoxSelectionChanged, AddressOf sfDataGrid1_CellComboBoxSelectionChanged

Private Sub sfDataGrid1_CellComboBoxSelectionChanged(ByVal sender As Object, ByVal e As CellComboBoxSelectionChangedEventArgs)
If e.GridColumn.MappingName = "ShipCityID" AndAlso e.SelectedIndex = 0 Then
TryCast(e.Record, OrderInfo).ShipCountry = "Canada"
End If
End Sub
```
