# VirtualListView.BeginUpdate Method 
 
Prevents changes in that window from being redrawn until the [EndUpdate()](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_WinControls_VirtualListView_EndUpdate.htm.md) method is called.
 
**Namespace:** [Aurigma.GraphicsMill.WinControls](https://www.graphicsmill.com/docs/gm5/N_Aurigma_GraphicsMill_WinControls.htm.md)
 **Assembly:** Aurigma.GraphicsMill.WinControls (in Aurigma.GraphicsMill.WinControls.dll)
 
## Syntax
  
```
Public Sub BeginUpdate
```

public void BeginUpdate()

## Remarks
  
Use this method when you add multiple items one by one to increase a performance. Do not forget to call [EndUpdate()](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_WinControls_VirtualListView_EndUpdate.htm.md) method when you have added all items which you need and want the control to display all of them.
