Grid View for ASP.NET MVC - How to add a column if the AutoGenerateColumns property is set to true

When the AutoGenerateColumns property is set to true, handle the GridViewSettings.DataBound event to add a column to the Grid View. Before adding the column, check whether a column already exists to avoid duplicate columns.

Razor
settings.DataBound = (sender, e) => { MVCxGridView grid = sender as MVCxGridView; if (grid.Columns.IndexOf(grid.Columns["CommandColumn"]) != -1) return; GridViewCommandColumn col = new GridViewCommandColumn(); col.Name = "CommandColumn"; col.ShowSelectCheckbox = true; col.VisibleIndex = 0; grid.Columns.Add(col); };
