How to use SuperToolTip in WinForms GridGroupingControl?

SuperToolTip

The SuperToolTip can be enabled for the grid using TableControl.MouseHover event. In this event, the tooltip duration and initial delay can also be set for SuperToolTip.

C#:

this.gridGroupingControl1.TableControl.MouseHover += TableControl_MouseHover;
 
private void TableControl_MouseHover(object sender, EventArgs e)
{
    string category2Str = "Category Test String";
    SuperToolTip st = new SuperToolTip();
    st.ToolTipDuration = 5;
    st.InitialDelay = 1000;
    if(string.IsNullOrEmpty(category2Str) == false)
    {
        ToolTipInfo ti = new ToolTipInfo();
        ti.Footer.Hidden = true;
        ti.Header.Text = "Category";
        ti.Header.TextAlign = ContentAlignment.MiddleCenter;
        ti.Body.Text = category2Str;
        st.Show(ti, MousePosition);
    }
}

VB:

AddHandler Me.gridGroupingControl1.TableControl.MouseHover, AddressOf TableControl_MouseHover
 
Private Sub TableControl_MouseHover(ByVal sender As Object, ByVal e As EventArgs)
    Dim category2Str As String = "Category Test String"
    Dim st As New SuperToolTip()
    st.ToolTipDuration = 5
    st.InitialDelay = 1000
    If String.IsNullOrEmpty(category2Str) = False Then
        Dim ti As New ToolTipInfo()
        ti.Footer.Hidden = True
        ti.Header.Text = "Category"
        ti.Header.TextAlign = ContentAlignment.MiddleCenter
        ti.Body.Text = category2Str
        st.Show(ti, MousePosition)
    End If
End Sub
