Casting a grid

I have a web form with several grids on it, and a procedure that cycles
through each grid to do a number of tasks, using for next, and am getting a
"Specified cast is not valid" error when I attempted to put the grid names
in an arraylist.

For sample purposes, we'll name the grids grid1, grid2, grid3.

when I manually set each grid, it works fine:

        dg = grid1
        GetData(dg)
        dg = grid2
        GetData(dg)
        dg=grid3
        GetData(dg)

but when I attempted to put the grids in an arraylist, I get the cast error:

    arrGrids.add("grid1")
    arrGrids.add("grid2")
    arrGrids.add("grid3")

    for i = 0 to arrGrids.Count-1
        dg = ctype(arrGrids(i), DataGrid)
        GetData(dg)
    next

How else can I do this? tia

arrGrids.add("grid1") adds a string "grid1".

arrGrids.add(grid1) will add the object grid1.

Don't know why I didn't catch that one, thanks! Must be a Monday. That did
the trick.
