Add column to end of grid programatically with auto generated columns

[Matt Greer]

I have a RadGridView with AutoGenerateColumns set to true. I want to add an additional column as the last column programatically.

What event is the best event on the RadGridView to listen to for this?


RadGridView.DataLoaded does not work, as this fires before the auto generated columns are created, placing my column before them.

RadGridView.AutoGeneratingColumn does not work, as I don't know how many columns my grid will have.


The best event I've found is RadGridView.SelectionChanged, as this will get fired once the grid is fully set up. But man this feels hacky and dirty.

I wish RadGridView had an AutoGeneratedColumns event, that fired after all the auto generated columns were created.


This thread: http://www.telerik.com/community/forums/silverlight/gridview/event-to-add-column-at-the-end.aspx
has an example that uses the DataLoaded event. The problem is the grid in the sample is not using auto generated columns.




I am using Telerik Controls version 2010.2.812.1040

Hi Matt Greer,

I have just tested adding of columns in the DataLoaded event and it worked correctly.
The code I used is:

private void clubsGrid_DataLoaded(object sender, EventArgs e)
{
    if (this.clubsGrid.Columns.Count > 0)
    {
        this.clubsGrid.Columns.Add(new GridViewSelectColumn()
                  {
                      DisplayIndex = this.clubsGrid.Columns.Count
                  });
    }
}

I have attached a sample project as well.

Kind regards,

Ahhhh, gotcha. I wasn't checking to see if Columns.Count > 0.

This does work. Although I'd still love to see an AutoGeneratedColumns event :)
