ProgressBarRenderer.DrawVerticalChunks Method

Draws a set of progress bar pieces that fill a vertical progress bar.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public static void DrawVerticalChunks(
	Graphics g,
	Rectangle bounds


Type: System.Drawing.Graphics
The Graphics used to draw the progress bar.
Type: System.Drawing.Rectangle
The Rectangle that specifies the bounds to be filled by progress bar pieces.


The operating system does not support visual styles.


Visual styles are disabled by the user in the operating system.


Visual styles are not applied to the client area of application windows.

Each progress bar piece drawn by this method spans the width of the bounds parameter. The number of progress bar pieces drawn is determined by the height of bounds and the values returned by ChunkSpaceThickness and ChunkThickness.

Before using this method, you should verify that the IsSupported property returns true.

The following code example uses the DrawVerticalChunks method in a Timer.Tick event handler to draw each increment of a progress bar. This code example is part of a larger example provided for the ProgressBarRenderer class.

// Handle the timer tick; draw each progressively larger rectangle.
private void progressTimer_Tick(Object myObject, EventArgs e)
    if (ticks < NumberChunks)
        using (Graphics g = this.CreateGraphics())
        progressTimer.Enabled = false;
