Remarks
To assign a FlyoutPanel to your TokenEdit control, use the RepositoryItemTokenEdit.PopupPanel property. When a user moves the mouse pointer over a selected token, the BeforeShowPopupPanel event fires. Handle it to customize the flyout panel that is about to pop up.
Event arguments expose the following properties:
e.Token- the hovered token;e.Value,e.Description- the value and description of the hovered token;e.DataObject- in bound mode, returns an Object that is the data source record. In unbound mode, returns the hovered token as an Object.e.DataSourceIndex- in bound mode, returns the index of a data source record. In unbound mode, returns the index of the hovered token within the RepositoryItemTokenEdit.Tokens collection.e.Bounds- flyout panel bounds.
The code below populates two flyout panel labels with the token description and the value of the corresponding data source record’s “Modified Date” column.
void TokenEdit1_BeforeShowPopupPanel(object sender, TokenEditBeforeShowPopupPanelEventArgs e) {
labelControl2.Text = e.Token.Description;
labelControl4.Text = (e.DataObject as DevExpress.DataAccess.Sql.DataApi.IRow)["ModifiedDate"].ToString();
