Access to the Ok/Accept Or Cancel Button of a RepositoryItemTimeSpanEdit?

问题

I need to know if there is a way to access to the events of the buttons inside a RepositoryItemTimeSpanEdit. Image to see the buttons I need the events for: Click Image

I have tried to access in the PopUp event and QueryPopUp, however I can't get the button in any way yet.

You can get this form through Form.OwnedForms property in Popup event. The type of this form is DevExpress.XtraEditors.Popup.TimeSpanEditDropDownForm, so you need just to find the form of this type. After that you can access buttons by using TimeSpanEditDropDownForm.OkButton property and TimeSpanEditDropDownForm.CloseButton property.
Here is example:

private void repositoryItemTimeSpanEdit1_Popup(object sender, EventArgs e)
{
    var popupForm = (TimeSpanEditDropDownForm)OwnedForms.FirstOrDefault(item => item is TimeSpanEditDropDownForm);

    if (popupForm == null)
        return;

    popupForm.OkButton.Click += OkButton_Click;
    popupForm.CloseButton.Click += CloseButton_Click;
}

private void OkButton_Click(object sender, EventArgs e)
{
    MessageBox.Show("Ok");
}

private void CloseButton_Click(object sender, EventArgs e)
{
    MessageBox.Show("Cancel");
}
