Remarks

The CustomDrawItemIndicator event allows you to custom draw item indicators. The Handled event argument must be set to true for the event handler to be in effect.

The following methods allow you to perform default rendering of the step progress bar components:

• DefaultDraw() - Draws the entire indicator.
• DefaultDrawFillIndicator() - Draws the indicator’s background.
• DefaultDrawImage() - Draws the indicator’s image.
• DefaultDrawIndicatorBorder() - Draws the indicator’s border.

Example

The example below handles the CustomDrawItemIndicator event to custom draw indicators. The event handler draws a rectangle around an indicator, and paints the default image inside the rectangle.

C#

  private void stepProgressBar1_CustomDrawItemIndicator(object sender, DevExpress.XtraEditors.Drawing.StepProgressBarItemIndicatorCustomDrawEventArgs e) {
    // Draw the default image.
    e.DefaultDrawImage();
    // Custom draw a rectangle around the indicators using the thickness and color of a connector.
    e.Cache.DrawRectangle(e.IndicatorBounds, e.GetIndicatorBorderPen().Color, stepProgressBar1.ConnectorLineThickness);
    e.Handled = true;
  }

VB.NET

  Private  Sub stepProgressBar1_CustomDrawItemIndicator(ByVal sender As Object, ByVal e As DevExpress.XtraEditors.Drawing.StepProgressBarItemIndicatorCustomDrawEventArgs)
    ' Draw the default image.
    e.DefaultDrawImage()
    ' Draw a rectangle with the connector's thickness and color around the indicators.
    e.Cache.DrawRectangle(e.IndicatorBounds, e.GetIndicatorBorderPen().Color, stepProgressBar1.ConnectorLineThickness)
    e.Handled = true
  End Sub
