  • Have you tried ItemDataBound Event ? – Thirisangu Ramanathan Sep 25 '14 at 10:04
  • DataGrid column headers have text boxes and the last column header has Button. I want button to remain "Disabled" if any of the text boxes are empty. I am new to WPF. – CodeLand Sep 25 '14 at 10:29
  • I have to reference something like this DataGrid.DataGridHeaderColumn[x].find("texboxt_I_looking_for"). I am not sure about the format, I am guessing based on my Asp.NET past – CodeLand Sep 25 '14 at 10:32

  • I have done something similar to in Button Click event to commit data (textbox values) to database. I am trying to do something with triggers in xaml to disable button not in code behind. – CodeLand Sep 25 '14 at 11:42
