ASPxClientComboBox.BeginUpdate Method

Prevents the client combobox editor from being rendered until the ASPxClientComboBox.EndUpdate method is called.

Declaration

BeginUpdate(): void

Remarks

The combobox editor allows a sequence of operations that affect its appearance and/or functionality to be performed on the client side, without having the editor render itself after each modification (for instance, multiple items within the editor can be dynamically added/removed at the same time). To do this, the code performing sequential changes to the editor must be enclosed within calls to the BeginUpdate and ASPxClientComboBox.EndUpdate methods. This improves performance, and avoids unnecessary render operations on the client side.
