I need to show tooltips on the elements of a RadForm TitleBar, like in the attached image.

things I've tried that didn't work:

setting the ToolTipText

this.FormElement.TitleBar.SystemButtons.Children[0].ToolTipText = "this is a tooltip";

using the ToolTipTextNeeded form event

class TestTooltipForm : RadForm

{

public TestTooltipForm()

{

InitializeComponent();

this.ToolTipTextNeeded += (sender, args) =>

{

args.ToolTipText = "a tooltip";

};

}

The only thing that seems to be working is instantiating a RadToolTip and showing it inside del ToolTipTextNeeded (ignoring the args parameter)

The problem with this method is that the tooltip stays visible forever, so I need to hide it on some event like 'form_mouseHover' which is kind of convoluted.

Is there a better way?

Hi Stefano,

You need to set the AutoToolTip property as well:

this.FormElement.TitleBar.SystemButtons.Children[1].ToolTipText = "Test1";

this.FormElement.TitleBar.SystemButtons.Children[1].AutoToolTip = true;

this.FormElement.TitleBar.SystemButtons.Children[2].ToolTipText = "Test2";

this.FormElement.TitleBar.SystemButtons.Children[2].AutoToolTip = true;

this.FormElement.TitleBar.SystemButtons.Children[3].ToolTipText = "Test3";

this.FormElement.TitleBar.SystemButtons.Children[3].AutoToolTip = true;

In addition, the first child is the help button which is not visible by default.

Should you have any other questions do not hesitate to ask.

Hello Stefano,

The tooltip can be accessed in the from's ToolTipTextNeeded event handler. Here is an example:

private void RadForm1_ToolTipTextNeeded(object sender, Telerik.WinControls.ToolTipTextNeededEventArgs e)

{

var item = sender as RadImageButtonElement;

if (item != null && item == this.FormElement.TitleBar.SystemButtons.Children[1])

{

e.ToolTip.ToolTipIcon = ToolTipIcon.Warning;

e.ToolTipText = "Test";

}

If you want more complex layout in the tooltip to consider using Screen Tips | Telerik Presentation Framework.

I hope this will be useful.
