How to get a list of visible columns server-side

[Al]

Hi ,

How can I find out which columns are visible in a server-side routine (some columns may have been shown/hidden with the header context menu)?

Hello Al,

You can traverse the Columns collection of the grid and check their Display and Visible properties:

List<GridColumn> columns = new List<GridColumn>();
foreach (GridColumn column in RadGrid1.MasterTableView.RenderColumns)
{
    if (column.Display == true && column.Visible)
    {
        columns.Add(column);
    }
}

Hope this helps.

Hi Rahul,

You can control the client-side visibility of the columns using their Display property. You can also traverse the get_columns() collection of the MasterTableView client-side object and determine which column is currently hidden or shown using the following method:
