BaseListBoxControl.CustomizeContextItem Event

Allows you to customize the context buttons for individual items.

Namespace: DevExpress.XtraEditors

Assembly: DevExpress.XtraEditors.v21.2.dll


public event ListBoxControlContextButtonCustomizeEventHandler CustomizeContextItem

Event Data

The CustomizeContextItem event's data class is DevExpress.XtraEditors.ViewInfo.ListBoxControlContextButtonCustomizeEventArgs.


By default, the BaseListBoxControl control displays the context buttons with the same properties in all items. The CustomizeContextItem event fires for each context button in each item before the BaseListBoxControl is displayed and allows you to customize the context buttons. Read the ListBoxControlContextButtonCustomizeEventArgs.Item property to determine the item being processed. The ListBoxControlContextButtonCustomizeEventArgs.ContextItem property returns the context button to be customized.

A code snippet below shows how to provide the custom appearance setting for the RatingContextButton displayed in a particular item.

private void listBoxControl1_CustomizeContextItem(object sender, DevExpress.XtraEditors.ViewInfo.ListBoxControlContextButtonCustomizeEventArgs e) {
    RatingContextButton rcb = e.ContextItem as RatingContextButton;
    if(rcb != null) {
        String item = e.Item as String;
        if(item != null && item == "California") {
            rcb.AppearanceNormal.ForeColor = Color.Red;

The result is shown below.
