Hi I have added a date column using
// Add a new column for the date
GridTemplateColumn gridTemplateColumn1 = new GridTemplateColumn();
gridTemplateColumn1.HeaderText = "Creation Date";
gridTemplateColumn1.SortExpression = "Date";
gridTemplateColumn1.UniqueName = "Date";
gridTemplateColumn1.DataField = "Date";
RadFileExplorer1.Grid.Columns.Add(gridTemplateColumn1);
But i cant see how to populate the column.
