![]() ![]() But as the CSS will be minified at some point I don't think it should count. I've used a bit of artistic license with the title of this post, while it's less than 10 lines of Razor, that doesn't include the CSS. I'm loving every minute so far but I'm sooo thankful for my coffee machine!!Īnyway, back to the subject in hand, in this post I'm going to be showing you how you can build a really simple, reusable, tooltip component for your Blazor applications. My wife and I also had our first child at the start of September which has been an amazing and interesting new challenge to take on. Since my last post, I've been working hard writing the first few chapters for my book, Blazor in Action – which should be out on MEAP (Manning Early Access Program) very very soon. Note that you should use the ToolTipController.SetToolTip, ToolTipController.SetTitle, ToolTipController.SetToolTipIconType and ToolTipController.SetSuperTip methods, to specify a tooltip for such a control in code.It has been so long since I've managed to get some time to write a blog post. If a tooltip is specified via the ToolTip, Title or SuperTip property, hovering the mouse pointer over the control results in a hint, which is controlled by the tooltip controller currently displayed. When a ToolTipController component is placed on a form, all controls publish the ToolTip, Title, ToolTipIconType and SuperTip properties (for instance, the ToolTip property’s caption in the Properties window is ‘ToolTip on ToolTipController1’). Tooltips, however, can still be displayed for them using the ToolTipController component. Non-DevExpress controls (for instance, the standard WinForms controls) do not implement the interface. GridControl1.ToolTipController = controller Private void Form1_Load(object sender, EventArgs e) The following example demonstrates how to create a ToolTip Controller in code and assign it to a WinForms Data Grid control. DevExpress controls implement the interface, and supply additional information to the ToolTipController via this interface. After a tooltip controller is assigned to the property, the appearance and behavior of hints in this control/component is determined by the assigned tooltip controller. ![]() To specify the type of tooltips to be displayed, use the ToolTipController.ToolTipType property.ĭevExpress controls and components provide the ToolTipController property, which allows a ToolTipController to be bound. A typical SuperToolTip contains a header, contents and footer regions, where you can display custom images: ![]() The following image shows a regular tooltip:Ī SuperToolTip object represents a tooltip that can contain multiple text and image regions. A tooltip’s contents are determined by the control for which the tooltip is displayed. In addition, a predefined or custom icon can be displayed within the tooltip. The ToolTipController supports regular tooltips and SuperToolTip objects.Ī regular tooltip can consist of the text and title region, either of which can be omitted. You can customize the hint window’s appearance, the time intervals that must pass before the hint is invoked or hidden, the type of tooltips, etc. The ToolTipController component enables you to customize the appearance and behavior of hints displayed for controls or their elements.
