The File Explorer gives you 2 columns out of the box, name and size. I want to use Name for my databases id field, and add "Display Name" or something to the control, but I want it to appear in front of the "Size" column. Needless to say I'm providing my own ContentProvider, too.
It works fine if I add the new column to the end of the list, but not if I try to insert it, or to "AddAt".
// Works ok, but not what I need
// Doesn't work like I need.
// Doesn't work like I need.RadFileExplorer1.Grid.Columns.AddAt(1, gridTemplateColumn1);
Oh --forgot to mention that I'm going to hide the existing Name column after that.
RadFileExplorer1.Grid.Columns.Display = false;
Any ideas what I might be doing wrong?
