Silverlight 3.0 Datagrid issue

Hi

If you clear all the columns of the datagrid and try to add columns to the grid again, out of bounds error is thrown. 

datagrid.columns.clear();

datagrid.columns.add(new datagridtextboxcolumn())

Have you bound the DataGrid to data before doing so?

I was having Out Of Bounds exceptions thrown while trying to access silverlight 3 datagrid.columns collection (it had been working in Silverlight 2). You can look at the thread on my issue for a couple things I noticed about this problem.

Hi,

   I reproduced your situation and nothing went wrong as long as i set the binding of my DataGridTextColumn. But the error message i get is different with yours. So i can just suggest you to set your Column's binding first. If you can provide more of your code block or desribe your situation more specificly so that i can repro your program more accurately i will be very appreciated.

   Anyway this is how my code block of doing so.

        private void btn_Click(object sender, RoutedEventArgs e)
        {
            mygrid.Columns.Clear();
            DataGridTextColumn tc = new DataGridTextColumn();
            tc.Binding = new Binding("Age");
            mygrid.Columns.Add(tc);
        }

Best Regards
