ToolTip on Outlook-style panelbar groups

[James]

I've set tooltips for each group element, however, when the groups are collapsed into icons along the bottom in the Outlook style there is no tooltip on those icons.  I'd like the little icons on the bottom to show the tooltip for that group element.  Is this possible?

Hi James,

Thank you for writing.

I confirm that there is not an easy way to set the tool tip text when the group elements transforms in toggle buttons in RadPanelBar. We will add this functionality in some of the next release.

Currently, you could work-around this by using ToolTiptextNeeded event of RadPanelBar. Please, review the code-block below:
 

private void radPanelBar1_ToolTipTextNeeded(object sender, Telerik.WinControls.ToolTipTextNeededEventArgs e)
{
    if (sender is RadToggleButtonElement)
    {
        RadToggleButtonElement item = ((RadToggleButtonElement)sender);

        int index =
            ((RadPanelBarOverFlow)this.radPanelBar1.PanelBarElement.
            Children[0].Children[1]).Items.IndexOf((RadItem)item);

        RadPanelBarGroupElement element =
            ((RadPanelBarGroupElement)this.radPanelBar1.
            Items[this.radPanelBar1.Items.Count - index - 1]);

        if (element.ToolTipText != String.Empty && element.ToolTipText != null)
        {
            e.ToolTipText = element.ToolTipText;
        }
        else if (element.Caption != String.Empty && element.Caption != null)
        {
            e.ToolTipText = element.Caption;
        }
    }
}

I hope this helps. I have updated your Telerik points for bringing our attention on this.

If you have other questions, do not hesitate to contact me again.
