How to get selected rows from grid

Hi Atanas.,
great its working!!

I only had to add one thing: The "value" property of the checkbox must be set to "@GetCheckboxValue(adressen)"

and this function implemented in the cs-file:

  public bool GetCheckboxValue(Adressen adr)
        {
            if (selectedItems != null && selectedItems.Contains(adr))
                return true;
            return false;
        }

Then the checkboxes get their values from the collection.

Best regards,
Frank
