Basic Configuration

The following example demonstrates the basic configuration for the TextArea.

    @(Html.Kendo().TextArea()
        .Name("textarea") // The name of the TextArea is mandatory. It specifies the "id" attribute of the TextArea.
        .Value("John Doe") // Set the value of the TextArea.
        .Rows(5) // Sets the number of rows
    )

Functionality and Features

Events

Here is a demo on using some basic events of the TextArea. For a full list, refer to the TextArea events documentation in the API section.

The following example demonstrates how to subscribe to events by a handler name.

  @(Html.Kendo().TextArea()
        .Name("textarea")
        .Events(e => e
            .Change("textarea_change")
        )
  )
  <script>
  function textarea_change() {
      // Handle the change event.
  }
  </script>

Referencing Existing Instances

To reference an existing Telerik UI TextArea instance, use the jQuery.data() method. Once a reference is established, use the TextArea client-side API to control its behavior.

The following example demonstrates how to access an existing TextArea instance.

  // Place the following after your Telerik UI TextArea for ASP.NET Core declaration.
  <script>
  $(function() {
      // The Name() of the TextArea is used to get its client-side instance.
      var textarea = $("#textarea").data("kendoTextArea");
  });
  </script>
