Getting Started with the DateInput

This tutorial explains how to set up a basic Telerik UI for ASP.NET Core DateInput and highlights the major steps in the configuration of the component.

You will initialize a DateInput component and set a default value. Finally, you can run the sample code in Telerik REPL and continue experimenting with different configurations.

Prerequisites

To successfully complete the tutorial, you need a project that is already configured to use the Telerik UI for ASP.NET Core components:

• You can use the Telerik REPL playground and skip installing the components on your system and configuring a project.

• You can prepare a Visual Studio project by following either of these guides:

  • Creating a new pre-configured project for the Telerik UI for ASP.NET Core components from a project template.

  • Manually configuring an existing project as described in the First Steps on Windows or First Steps on Mac articles.

1. Prepare the CSHTML File

The first step is to add the required directives at the top of the .cshtml document:

• To use the Telerik UI for ASP.NET Core HtmlHelpers:

  @using Kendo.Mvc.UI
  

• To use the Telerik UI for ASP.NET Core TagHelpers:

  @addTagHelper *, Kendo.Mvc
  

2. Initialize the DateInput

Use the DateInput HtmlHelper or TagHelper to add the component to the page:

• The Name() configuration method is mandatory as its value is used for the id and the name attributes of the DateInput element.
• The Label() configuration specifies the label text of the DateInput. Optionally, you can enable the Floating feature of the label.

Do not set the Name() option when using DateInputFor. The [ComponentName]For method automatically sets the control's Name() to the field it is bound to. For more information, see the Fundamentals article.

    @(Html.Kendo().DateInput()
        .Name("dateinput")
        .Label(label=>{
            label.Content("DateInput:")
        })
    )

    @addTagHelper *, Kendo.Mvc

    <kendo-dateinput name="dateinput">
        <label content="DateInput:" />
    </kendo-dateinput>

3. Set a Default Value

The next step is to set a default value. The following example shows how to use the .Value() method of the DateInput, to set the current date as a value of the component.

    @{
       var defaultDateInput = DateTime.Now;
    }

    @(Html.Kendo().DateInput()
        .Name("dateinput")
        .Label(label=>{
            label.Content("DateInput:")
        })
        .Value(defaultDateInput)
    )

    @addTagHelper *, Kendo.Mvc
    @{
         var defaultDateInput = DateTime.Now;
    }

    <kendo-dateinput name="dateinput" value="defaultDateInput">
        <label content="DateInput:" />
    </kendo-dateinput>

4. (Optional) Reference Existing DateInput Instances

To use the client-side API of the DateInput and build on top of its initial configuration, create a reference to the DateInput instance. Once you get a valid reference, you can call the respective API methods:

1. Use the .Name() (id attribute) of the component instance to get a reference.

       <script>
           $(document).ready(function() {
               var dateinputReference = $("#dateinput").data("kendoDateInput"); // dateinputReference is a reference to the existing DateInput instance of the helper.
           })
       </script>
   

2. Use the DateInput client-side API to control the behavior of the control. In this example, you will use the enable method to disable the input.

       <script>
           $(document).ready(function() {
               var dateinputReference = $("#dateinput").data("kendoDateInput"); // dateinputReference is a reference to the existing DateInput instance of the helper.
               dateinputReference.enable(false); // enable or disable the input 
           })
       </script>
