Hi Mitch,
Thank you for your interest in Syncfusion Products.
We can set the tooltips to GroupBarItem using GroupBar's MouseMove event. Please refer the below code snippets that illustrates this:
private void groupBar1_MouseMove(object sender, MouseEventArgs e)
{
if (this.groupBar1.HighlightItem != -1)
{
ToolTipInfo tooltip = new ToolTipInfo();
tooltip.Body.Text = this.groupBar1.GroupBarItems[this.groupBar1.HighlightItem].Text;
this.superToolTip1.Show(tooltip, MousePosition);
}
}
Please refer the below sample for more details:
