Hi,
I try to draw a history graph in the grid column. In the graph column I'm getting the text "Collection". Drawn graph is over writing on the text. In which case I will get this text "Collection". How I can remove this.

 

Regards
Sasee.G

  Hi,
  
  This is a normal behaviour of the Grid. While drawing it knows nothing about custom painting and if there is no specified format, the grid takes a text by calling object.ToString() method. In your case it will be 'Collection'
  
  There are many ways to resolve the problem.
  
  1. Setup an EmptyFormat for the property, returning the collection:

  class YourClass
  {
      [Format(typeof(EmptyFormat))]
      IList History
      {
         ...
      }
  }

  
  2. Setup this format for the specified column:
  
  

  grid.Headers[0]["History"].Format = new EmptyFormat();

  
  3. Replace text in the grid.PaintCell event:

  grid.PaintCell += delegate(object sender, PaintCellEventArgs e)
  {
     if(e.Cell.Column != null && e.Cell.Column.Id == "History")
     {
         e.Text = string.Empty;
         e.PaintAll();
         e.Handled = true;
         
         //your code here   
         ...
     }
  };
