Environment

Product

TreeList for Progress® Telerik® UI for ASP.NET Core

Description

How can I add a checkbox column to the TreeList which will set an initial checked or unchecked state of the checkboxes based on the model values?

Solution

Use the template method of the TreeList column.

columns.Add().Field(e => e.CheckBoxColumnField).Template(
        "#if(CheckBoxColumnField == true){#" +
            Html.Kendo().CheckBox().Name("name#:CheckBoxColumnField#").HtmlAttributes(new { @class = "CheckBoxColumnField" }).Checked(true).ToHtmlString() +
        "#}else{#" +
            Html.Kendo().CheckBox().Name("name#:CheckBoxColumnField#").HtmlAttributes(new { @class = "CheckBoxColumnField" }).ToHtmlString() +
        "#}#"
    );
