Event Data

The QueryPopUp event's data class is CancelEventArgs. The following properties provide information specific to this event:

Property	Description
Cancel	Gets or sets a value indicating whether the event should be canceled.

Remarks

If a TimeEdit control’s RepositoryItemTimeEdit.TimeEditStyle property equals TimeEditStyle.TouchUI, clicking its action button invokes a pop-up window. End-users can slide through this pop-up to modify the TimeEdit control’s BaseEdit.EditValue.

When a TimeEdit attempts to open its pop-up window, the QueryPopUp event occurs. Handle it to allow or prohibit opening the pop-up. The following code demonstrates how to prevent a TimeEdit from displaying its pop-up window.

C#

private void timeEdit1_Properties_QueryPopUp(object sender, CancelEventArgs e) {
     if (. . .) e.Cancel = true;
 }

VB.NET

Private Sub timeEdit1_Properties_QueryPopUp(ByVal sender As Object, ByVal e As CancelEventArgs)
     If ... Then
     e.Cancel = True
     End If
 End Sub

If the QueryPopUp event was not canceled, after the pop-up window is completely opened, the TimeEdit.Popup event occurs. Use the PopupBaseEdit.IsPopupOpen property to get whether the pop-up window is currently displayed.

Attempting to close a TimeEdit control’s pop-up window triggers a similar sequence for the TimeEdit.QueryCloseUp, TimeEdit.CloseUp and TimeEdit.Closed events.
