How to programmatically display a tooltip for a control via the ToolTipController component

Description:
I use the ToolTipController.ShowHint method to display a tooltip near an edit box. However, it only works the first time. What should I do to display the tooltip again for the same edit box?

Answer:
By design, a tooltip for a control is displayed just once. When showing a tooltip programmatically, you can work around this situation by calling the HideHint method before ShowHint. Here is the code:

C#
toolTipController1.HideHint();  
toolTipController1.ShowHint("A tooltip", textBox1, DevExpress.Utils.ToolTipLocation.RightCenter);

    Hi, this is not working for me.
    The tooltip is displayed in a wrong location.

    The control which I would like to bound the tooltip is inside a group control of a mdichild form.
    The MDI main form has menu, toolbar, etc… on top and an accordion on the left.
    DX 20.1.6
    thanks

    Visual Basic
    Dim Args As New DevExpress.Utils.ToolTipControllerShowEventArgs()
Args.IconType = DevExpress.Utils.ToolTipIconType.Information
Args.SelectedControl = ddbFunzioni
Args.Title = "Sono presenti allegati"

Me.ToolTipController1.ShowHint(Args, ddbFunzioni)
