The Telerik UI Dialog TagHelper and HtmlHelper for ASP.NET Core are server-side wrappers for the Kendo UI Dialog widget.
The Dialog is a modal popup that brings information to the user. It also enables the user to perform specific actions by using action buttons, for example, to enter data or choose between options. If needed, the Dialog can accommodate complex UI elements that require the focus of the user. The Dialog is a subtype of the Kendo UI for jQuery Window with the most prominent differences being the added actions and predefined dialogs.
Initializing the Dialog
In the most common use case, the Dialog opens as a result of a user action rather than of the
load event of the page. To achieve this, you must initialize the widget as non-visible and open it when needed.
The following example demonstrates how to define the Dialog.
@(Html.Kendo().Dialog() .Name("dialog") // The name of the Dialog is mandatory. It specifies the "id" attribute of the widget. .Title("Software Update")// Set the title of the Dialog. .Content("Do you agree terms and conditions?") // Define the content of the Dialog. .Visible(false) // The widget will be initialized as invisible. )
<kendo-dialog name="dialog1"> <content>Dialog contents</content> </kendo-dialog>
The Dialog provides default configuration options that you can set during its initialization—height and width, custom action buttons, title, close buttons, animation effects, and so on.
The following example demonstrates a basic Dialog configuration.
<kendo-dialog name="dialog" title="Software Update" modal="false" on-close="dialog_close"> <content> <p>A new version of <strong>Kendo UI</strong> is available. Would you like to download and install it now?<p> </content> <actions> <action text="Skip this version"> </action> <action text="Remind me later"> </action> <action primary="true" text="Install update"> </action> </actions> </kendo-dialog>
