adding delete sQL

Hi,

I am new to WPF and in this example I am basically trying to add the following delete functionality. 

DELETE FROM InspectorTime  WHERE TimeID=@TimeID

Can anyone guide me?  Txs

Here's the xaml code:

               
               
               
               
               
               
               
               
                    CellTemplate>
                       
                           
                       
                    CellTemplate>
               

           


Here's the ref code:

        private void VoidButton_Click(object sender, RoutedEventArgs e)
        {
           
            if (MessageBox.Show("Are you sure you want to void the time?", "Void Inspection", MessageBoxButton.YesNo, MessageBoxImage.Question) == MessageBoxResult.Yes)
            // delete SQL query
         {
            try
             {

                 MessageBox.Show("Information Updated.", "Update");
             }
             catch (Exception oEx)
             {
                 MessageBox.Show("Information not Updated.", "Update");
             }
       
          }
        }
