If you want to ask user before deleting record then write the following code in your screen code editor.
Namespace LightSwitchApplication Public Class EditableCustomersGrid Private Sub gridDeleteSelected_Execute() ' Write your code here. If ShowMessageBox("Are you sure you want to delete this record?", "Confirm Delete", MessageBoxOption.YesNo) = MessageBoxResult.Yes Then Dim cust As Customer cust = Me.Customers.SelectedItem If Customers.CanDelete Then cust.Delete() Me.Save() '//Save immediately .. End If End If End Sub End Class End Namespace
