Single click edit in WPF DataGrid

Question

I want the user to be able to put the cell into editing mode and highlight the row the cell is contained in with a single click. By default, this is double click.

I know that I am a bit late to the party but I had the same problem and came up with a different solution:

     public class DataGridTextBoxColumn : DataGridBoundColumn
 {
  public DataGridTextBoxColumn():base()
  {
  }

  protected override FrameworkElement GenerateEditingElement(DataGridCell cell, object dataItem)
  {
   throw new NotImplementedException("Should not be used.");
  }

  protected override FrameworkElement GenerateElement(DataGridCell cell, object dataItem)
  {
   var control = new TextBox();
   control.Style = (Style)Application.Current.TryFindResource("textBoxStyle");
   control.FontSize = 14;
   control.VerticalContentAlignment = VerticalAlignment.Center;
   BindingOperations.SetBinding(control, TextBox.TextProperty, Binding);
    control.IsReadOnly = IsReadOnly;
   return control;
  }
 }

        
        
            
            
            
            
        
    

As you can see I wrote my own DataGridTextColumn inheriting everything vom the DataGridBoundColumn. By overriding the GenerateElement Method and returning a Textbox control right there the Method for generating the Editing Element never gets called. In a different project I used this to implement a Datepicker column, so this should work for checkboxes and comboboxes as well.

This does not seem to impact the rest of the datagrids behaviours..At least I haven't noticed any side effects nor have I got any negative feedback so far.
