Datagrid selection

Datagrid selection

  Unfortunately there is no easy way to achieve this.
  
  The datagrid control has a method called ProcessGridKey which gets to look at any key presses before you - the select all code is in here.  You can find this method using Refletor.  The good news it is protected, so you can override it and handle the ctrl+a (or any other keys) yourself.
  
  Hope thats useful.

  Ok, you need to create a descendant datagrid, and override the ProcessGridKey method.  Something like this in c# (apologies for any typo's I'm writing this straight into the forum).
  
  public class MyNewDataGrid : DataGrid
  {
     protected override bool ProcessGridKey(KeyEventArgs ke)
     {
        if (ke.KeyCode == Keys.A && ke.Control)
        {
          //Do whatever you want to do here instead of select all...
        }
        else
           return base.ProcessGridKey(ke); //let the base class deal with other keys...
     }
  }
  
  That should give you an idea.

  I'm sorry, I've looked into this a bit more, and the code sample I gave you doesn't work (the method i was overriding isn't virtual! Oops).  I've looked into it a bit more, and can't seem to get work you need.
  
  Sorry.
