EditTemplate with DropDownList

[Robert Madrian]

Hello,

Isn't it possible to use a Kendo DropDownList in the Grid EditTemplate and pass the Parameter for the Dropdown with the Kendo Template Syntax like this: new {mitgliedid = "#: Mitglied_ID #"}

Here a example:

@(Html.Kendo().DropDownList()
      .Name("products")
      .DataTextField("ProductName")
      .DataValueField("ProductID")
      .DataSource(dataSource => { dataSource.Read(read => read.Action("Lookup", "Berechtigung", new {mitgliedid = "#: Mitglied_ID #"}))
          .ServerFiltering(true); })
          .ToClientTemplate()
      )

 

or is the only way to pass that parameter in the Grid Edit Event (e.model)?

Hi Robert,

This syntax could not be used within the editor template for passing additional data, but you can take a look at the following HowTo example, where the Data function is used for returning additional parameters:

• https://docs.telerik.com/aspnet-mvc/helpers/grid/how-to/editing/grid-incell-editing-cascading-dropdownlist

In the editor template:

...
 dataSource.Read(read => read.Action("GetVendors", "Home").Data("filterVendors"))

And in the main view:

function getCurrentEditedModel() {
      var grid = $("#Grid").data("kendoGrid");
      var editRow = grid.tbody.find("tr:has(.k-edit-cell)");
      return grid.dataItem(editRow);
  }

  function filterVendors() {
      var model = getCurrentEditedModel();
      return {
          customerId: model.CustomerId
      };
  }

Hope this helps.
