The checkboxes functionality in the DropDownTree provides various configuration options.

You can define the Checkboxes configuration option by:

  • Using a Boolean value.

        .DataSource(dataSource => dataSource
            .Read(read => read
                .Action("Read_DropDownTreeData", "Home")
  • Using inner (detailed) configuration options.

    • The Name() configuration sets the name attribute of the checkbox inputs. That name will be used when a form is being posted to the server.
    • The CheckChildren() option indicates whether checkboxes of child items will be checked when the checkbox of a parent item is checked. This option also enables tri-state checkboxes with an indeterminate state. CheckChildren() is disabled automatically, if filtering is enabled. Enabling both filtering and CheckChildren() at the same time could lead to ambiguous scenarios. Currently this scenario is not supported by the DropDownTree.
    • The TemplateId() option allows you to define a script template which will be used for the rendering of the checkboxes. Similarly, the Template() option allows the setting of an inline string template.

      @(Html.Kendo().DropDownTree() .Name("dropdowntree") .DataTextField("Name") .Checkboxes(checkboxes => checkboxes .Name("checkedFiles") .CheckChildren(true) .TemplateId("checkbox-template") ) .DataSource(dataSource => dataSource .Read(read => read .Action("Read_DropDownTreeData", "Home") ) ) )
