Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Occurs when the user changes the dock position of the custom task pane, or when code changes the value of the DockPosition property.
public:
event EventHandler ^ DockPositionChanged;event EventHandler DockPositionChanged;member this.DockPositionChanged : EventHandler Event DockPositionChanged As EventHandler Event Type
Examples
The following code example demonstrates an event handler for the DockPositionChanged event. This event handler changes the horizontal or vertical arrangement of controls on the task pane by modifying the FlowDirection property of a FlowLayoutPanel on the task pane. This code example assumes that the task pane contains a UserControl named MyUserControl, and the UserControl contains a FlowLayoutPanel named FlowPanel. This example is part of a larger example provided for CustomTaskPane.
private void myCustomTaskPane_DockPositionChanged(object sender, EventArgs e)
{
Microsoft.Office.Tools.CustomTaskPane taskPane =
sender as Microsoft.Office.Tools.CustomTaskPane;
if (taskPane != null)
{
// Adjust sizes of user control and flow panel to fit current task pane size.
MyUserControl userControl = taskPane.Control as MyUserControl;
System.Drawing.Size paneSize = new System.Drawing.Size(taskPane.Width, taskPane.Height);
userControl.Size = paneSize;
userControl.FlowPanel.Size = paneSize;
// Adjust flow direction of controls on the task pane.
if (taskPane.DockPosition ==
Office.MsoCTPDockPosition.msoCTPDockPositionTop ||
taskPane.DockPosition ==
Office.MsoCTPDockPosition.msoCTPDockPositionBottom)
{
userControl.FlowPanel.FlowDirection =
System.Windows.Forms.FlowDirection.LeftToRight;
}
else
{
userControl.FlowPanel.FlowDirection =
System.Windows.Forms.FlowDirection.TopDown;
}
}
}
