option from the drop-down list in the Space section of the toolstrip. The Evenly option

spaces the components 20 pixels apart. If you want to customize the number of pixels
between the components, type a number into the drop-down list.Next, click Apply Horizontally or Apply Vertically. For example, select Evenly
