Delete Row from Child Table

[Richard Harrigan]

Hi,

I am using the following code to Delete a row from  the RadGridView. This works for the first level in the hiarchy.  However, on the second level the SelectedItem == null. 

==================================

this

 

 

.AddHandler(UIElement.KeyDownEvent, new KeyEventHandler(MouseDownOnCell), true);

 

private

 

 

void MouseDownOnCell(object sender, KeyEventArgs args)

 

{ 

 

  

 

    if

 

 

(args.Key == Key.Delete && this.RadGridView1.SelectedItem != null)

 

    {

 

 

        MyDataContext.DomainContext.Customers.Remove(RadGridView1.SelectedItem as Customer);

 

    }

 

 

 

 

 

}

 

========================================

Hi Richard Harrigan,

RadGridView has a built-in support for record deletion - when the Delete key is pressed all selected items will be deleted. Depending on your scenario this functionality might not work - if the hierarchy items are items that are retrieved using an Ria Services associations the built-in functionality will not work since the list of associations does not support remove operations ( it is not IList).

Fortunately one of my colleagues has created a sample where with a little bit of tweaking the deleted operation is enabled for child grids as well.

Could you please take a look at the attached sample and determine if the proposed solution can be used in your scenario.

Sincerely yours,

Hi Milan,

I'm sorry but I could't get it to compile.  Is it possible that you point out the specific changes made to enable delete and insert child row from the Insert and Delete keys.

Thanks
Rich

Hi Richard Harrigan,

Unfortunately the changes are not trivial. Could you please paste some of errors?
