title: DevExpress ASPxGridLookup set selected value when the key field name has multiple fields
body: <p>I am using a DevExpress ASPxGridLookup with a KeyFieldName with multiple fields such as "field1;field2;field3".  I am having trouble trying to set the selected value.</p>
  
  <p>I have another one that just has one field for the key.  So, it works on the server side when I do something like the following:
  lkMyControl.DataBind();
  lkMyControl.Text = "SelectedKey";</p>
  
  <p>But when I try to do something similar with the control with multiple keys, the text just stays blank.  I have tried setting the Text property using the text in the same format as would be displayed on the control.  But it just stays blank.  I also tried lkMyControlWithMultipleKeyFields.GridView.Selection.SelectRowByKey("1;2;3").  But I just get an exception.</p>
