BeginUpdate Method (ImageBox)
Summary
Stops the viewer from being updated if any change is applied. This is useful to increase the control speed efficiency.
Syntax
public virtual void BeginUpdate()Public Overridable Sub BeginUpdate()public:virtual void BeginUpdate();
Remarks
The BeginUpdate method will cause the control not to call the System.Windows.UIElement.InvalidateMeasure method when any changes to the control properties or the image is applied. When the user calls the EndUpdate method, the viewer will call System.Windows.UIElement.InvalidateMeasure to show all the changes made. This is useful for better visual results and for speed efficiency.
Calls to BeginUpdate and EndUpdate are accumulative, you can call BeginUpdate as many times as you want and you must call the EndUpdate equivalent times to cause the update to happen.
Example
For C#/VB examples, refer to Flip.
