Examples

The following code example compares the resizing and relocating behavior of two Button controls to a worksheet. The Click event handler of the first button adjusts the Height and Width properties of the button so that the button changes size, but remains in the same location on the worksheet. The Click event handler of the second button adjusts the Top and Left properties of the button so that the button changes location on the worksheet, but stays the same size.

This example is for a document-level customization.

private void ModifySizeAndLocation()
{
    Microsoft.Office.Tools.Excel.Controls.Button sizeButton =
        this.Controls.AddButton(25, 30, 100, 25,
        "sizeButton");
    sizeButton.Name = "sizeButton";
    sizeButton.Text = "Click to resize";
    sizeButton.Click += new EventHandler(pointButtons_Click);

    Microsoft.Office.Tools.Excel.Controls.Button locationButton =
        this.Controls.AddButton(25, 150, 100, 25,
        "locationButton");
    locationButton.Name = "locationButton";
    locationButton.Text = "Click to move";
    locationButton.Click += new EventHandler(pointButtons_Click);
}
