Kendo Grid DropDownList不起作用

Question

Cannot bind DropDownList in kendo grid. it works fine if it's not inside the grid. I try to use

@(Html.Kendo().DropDownList()
                                      .Name("RegionId")

                                      .OptionLabel("[|[Select...]|]")
                                      .DataTextField("Name")
                                      .DataValueField("Id")
                                      .DataSource(source =>
                                      {
                                          source.Read(read =>
                                          {
                                              read.Action("FindAll", "region")
                                                  .Data("filterRegion");
                                          })
                                           .ServerFiltering(true);

                                      })
                                      .HtmlAttributes(new { @required = "" })
                                      .Enable(false)
                                      .AutoBind(false)
                                      .CascadeFrom("CountryId")
                                       .ValuePrimitive(true).HtmlAttributes(new { @required = "" })
    )

and its bind as a text box, not drop-down list. how to make it bind drop-down list? note: the values do not have a relation in a database I need to just columns and make it by code.

Answer 1

It is not as simple as you may think I am afraid. The entire implementation can be found in the documentation of Telerik .

In a few words you have to:

1. Create an object (Text-Value or Id-Label) to bind to your column

2. Create an editor template for this class

    @(Html.Kendo().DropDownList() .Name("Employee") // The name of the widget should be the same as the name of the property. .DataValueField("EmployeeID") // The value of the dropdown is taken from the EmployeeID property. .DataTextField("EmployeeName") // The text of the items is taken from the EmployeeName property. .BindTo((System.Collections.IEnumerable)ViewData["employees"]) // A list of all employees which is populated in the controller. ) 

3. Decorate your property with [UIHint("ObjectEditor")]
