Remarks
Use the following properties to enable HTML tags in tooltips:
- ToolTipController.AllowHtmlText — for all regular and super tooltips managed by this controller.
- BaseControl.AllowHtmlTextInToolTip — overrides the controller’s setting for a regular tooltip assigned to this control. To specify the tooltip’s content, use the BaseControl.ToolTip property.
SuperToolTip.AllowHtmlText
— overrides the controller’s setting for a particular super tooltip. To assign a super tooltip to a control, use the BaseControl.SuperTip property.- ToolTipItem.AllowHtmlText — overrides the previous setting for a particular item (area) in a super tooltip. To specify the item’s content, use the ToolTipItem.Text property.
Example
This example shows how to create a super tooltip with a hyperlink and assign it to a SimpleButton.
The button’s SuperTip property allows you to specify a super tooltip. Use the ToolTipController.AllowHtmlText, SuperToolTip.AllowHtmlText
, or ToolTipItem.AllowHtmlText property to enable HTML tags. Handle the ToolTipController.HyperlinkClick event to respond to a click on the hyperlink.
The SuperToolTip Editor allows you to create super tooltips in the designer. To invoke the editor, click the SuperTip property’s ellipsis button in the Properties window.
If you create a tooltip in the designer, you still need to handle the HyperlinkClick event in code. Use the Properties window to assign an event handler.
The example below shows how to create a super tooltip in code.
using DevExpress.Utils;
using System.Diagnostics;
private void Form1_Load(object sender, EventArgs e) {
// Access the controller that manages tooltips for all controls:
ToolTipController defaultTooltipController = DevExpress.Utils.ToolTipController.DefaultController;
// Create and customize a SuperToolTip:
SuperToolTip sTooltip = new SuperToolTip();
SuperToolTipSetupArgs args = new SuperToolTipSetupArgs();
args.Title.Text = "Header";
args.Contents.Text = "This tooltip contains a hyperlink. Visit the <href=http://help.devexpress.com>DevExpress Knowledge Center</href> to learn more.";
args.ShowFooterSeparator = true;
args.Footer.Text = "Footer";
sTooltip.Setup(args);
// Enable HTML Text Formatting for the created SuperToolTip:
sTooltip.AllowHtmlText = DefaultBoolean.True;
//..or enable this feature for all tooltips:
//defaultTooltipController.AllowHtmlText = true;
// Respond to clicking hyperlinks in tooltips:
defaultTooltipController.HyperlinkClick += defaultTooltipController_HyperlinkClick;
// Assign a SuperToolTip to the button:
simpleButton1.SuperTip = sTooltip;
}
void defaultTooltipController_HyperlinkClick(object sender, HyperlinkClickEventArgs e) {
Process process = new Process();
process.StartInfo.FileName = (e.Link);
process.StartInfo.Verb = "open";
process.StartInfo.WindowStyle = ProcessWindowStyle.Normal;
try {
process.Start();
}
catch { }
}
