How to: Use a callback to change another control's content when a radio button list's selection changes
2 minutes to read
This example demonstrates how to use callbacks to modify the content of a control (ASPxTextBox, in this example) when the ASPxRadioButtonList’s value changes.
The PerformCallback method generates the server-side ASPxCallbackPanel.Callback event that allows you to modify the text box content depending on the value received from the radio button list.
As a result, the text box’s mask changes when the radio button list’s selected value changes.
