If I understand you correctly, you're trying to set the Grid.Column="0" Grid.ColumnSpan="5" Grid.Row="1" in code instead of xaml?

If so, you need to use the methods on the Grid class itself.  These properties are Attached Properties, they are part of the Grid class, but can be "attached" to any UIElement.

For example, if you're doing it in the codebehind, you could write:

Grid.SetColumn(this.TopStackPanel, 0);
Grid.SetRow(this.TopStackPanel, 1);
Grid.SetColumnSpan(this.TopStackPanel, 5);

If you want details, you can read up on Grid.SetRow and the other related Attached Properties.

If I understand you completely -

Setup your form using the designer, and set the appropriate rows/columns for your controls.


Basically, when you click the button, you can have an event handler attached to the button (on button's Click event).  The event handler could go through each of your "controls", and change their columns.

Just call, for each control:

    Grid.SetColumn(theControl, System.Math.Max(0, Grid.GetColumn(theControl) - 1)); // Move "theControl" one space left in the grid, but not past column 0


That will "move" the control.
