C#

using DevExpress.XtraPrinting.Control;
// ...

private void printControl1_BrickClick(object sender, BrickEventArgs e) {
    if (e.Brick as VisualBrick != null) {
        // Change the background color.
        (e.Brick as VisualBrick).BackColor = Color.Red;

        // Redraw the brick.
        this.printControl1.InvalidateBrick(e.Brick);
    }
}

VB.NET

Imports DevExpress.XtraPrinting.Control
' ...

Private Sub printControl1_BrickClick(ByVal sender As Object, ByVal e As BrickEventArgs) _
Handles printControl1.BrickClick

    If TryCast(e.Brick, VisualBrick) IsNot Nothing Then
        ' Change the background color.
        CType(e.Brick, VisualBrick).BackColor = Color.Red

        ' Redraw the brick.
        Me.printControl1.InvalidateBrick(e.Brick)
    End If
