Column.Index is not reflecting immediately in TDBGrid

I have a TDBGrid and have a Client dataset associated through a TDataSource. When i try to re-arrange the columns of the grid programtically this works fine when there are one or more columns in the grid.

Lets say, i made all the columns visible to false. So, the grid does not have any columns yet. Now, when i set the Index of column at 11 to 0.

Columns[iColIndx].Index := iNewColIndex;
// Assume iColIndx = 11 and iNewColIndex = 0

Columns[iNewColIndex].Visible := True;
//Making the column visible

The above assignment of column index is not getting reflected in the Grid. If i try setting it for twice or thrice, then it is getting reflected. Am i missing anything?

I solved it. I have assigned OnDrawDataCell of the grid for drawing the gradients, but I was not calling the DefaultDrawDataCell from there. Moreover, the DefaultDrawing property was turned off.

After setting DefaultDrawing and calling DefaultDrawDataCell from within the DrawDataCell event handler, it is working fine now.
