    I have created a grid with 3 columns and I am able to detect a row selection on the client side.

    I want to query the row for an ID attribute, so that I can pass this ID to a server function.

    I have tried using a hidden column but when I do that my call to

    getCellByColumnUniqueName fails because the cell doesn't exist.

    surely this is a fairly common requirement.

    Hi Tim,

    I had the same issue when I first tried to have a hidden unique identifier column. The trick is understanding which methods of hiding a column happen in which steps of the page lifecycle. If the column is removed before the RadGrid is initialized, it literally won't exist on the page to reference (or make visible again). The way I handled this was to wire-up the OnGridCreated client-side method and hide the column at that point. The column is still there, only hidden - so you can reference it and make it visible if needed.

    Here's an example.
    function RadGrid1_OnGridCreated(sender, eventArgs) {
        var grid = sender;
        var MasterTable = grid.get_masterTableView();

    Hope this helps!
