If I have a control (combobox, with a SelectionChanged-event in code-behind) in DataGrid.
So, from _SelectionChanged-event, can I get reference of it's container-cell of the grid?
Plz Help!!
<DataGridTemplateColumn Width="100">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding Path=QuotationItemCode}"/>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
<DataGridTemplateColumn.CellEditingTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<ComboBox Height="22" Width="100" Name="cmbQuotationItemCode"
ItemsSource="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}, Path=DataContext.vwProducts}"
DisplayMemberPath="itM_Code"
SelectedValuePath ="itM_Id"
Tag="{Binding RelativeSource={RelativeSource Self}, Path=SelectedItem.Row[2]}"

You can walk the visual tree up from the ComboBox until you hit a DataGridCell, using VisualTreeHelper like this:
private static T FindAncestor<T>(DependencyObject child) where T : DependencyObject
{
var parentObject = VisualTreeHelper.GetParent(child);
if(parentObject == null || parentObject is T) {
return (T)parentObject;
}
return FindAncestor<T>(parentObject);
}
private void cmbQuotationItemCode_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
var cell = FindAncestor<DataGridCell>((DependencyObject)sender);
...
}
That said, don't forget about DataGridTemplateColumn.CellStyle - perhaps you can solve your problem with a Style!
