Hello,
if i have in razor this dropdownlist
@(Html.Kendo().DropDownList()
          .Name("category")
          .OptionLabel("Select a product...")
          .DataTextField("ProductName")
          .DataValueField("ProductID")
          .HtmlAttributes(new { style = "width:200px" })
          .DataSource(source => source.Read("ProductListData", "Controls"))
          .Events(ev => ev.Change("change"))


)

how can i use in the same view, the value of the dropdownlist using razor syntax?
i was looking for something like @Html.Kendo().DropDownList("category").Value()...

Regards,
Daniel

P.S:i think i put first this same post also to Web UI\DropDownList,please excuse me.

Hello Daniel,

Basically in the View you set the Value for the components from variables/viewmodels passed from the controller, you cannot get the value from the widget you are initializing.

If you pass the value from let's say ViewBag:

@(Html.Kendo().DropDownList()

          .Name("category")

          .OptionLabel("Select a product...")

          .DataTextField("ProductName")

          .DataValueField("ProductID")

          .HtmlAttributes(new { style = "width:200px" })

          .DataSource(source => source.Read("ProductListData", "Controls"))

          .Events(ev => ev.Change("change"))

          .Value(ViewBag.SomeValuePassedFromController)



)

Then you on the other places where you need that value you should again use the ViewBag to retrieve it.
