Why SelectedIndex(2) always return the 0 index value on the dropdownlist

[Phillip]

I have the following:

@(Html.Kendo().DropDownListFor(model => model.RecurringTypeID)
    .SelectedIndex(0) //Select 1st item.
    .DataTextField("Text")
    .DataValueField("Value")
    .BindTo(Model.RecurringType)
    .HtmlAttributes(new { style = "font-size:11px;width: 175px;" })
    .Events(e =>
        {
            e.Change("OnChangeRecurringType");
        })
)

Why  .SelectedIndex(0), .SelectedIndex(1), or .SelectedIndex(2) always return the 1st value on the dropdownlist.

Hello Phillip,

The described behavior is actually expected, because the widget will ignore the SelectedIndex option if value is defined, which is exactly the case when DropDownListFor extension is used. Basically, the DropDownListFor method will retrieve the name and value from the specified model. Hence it will use the model value instead of the index, because the defined value has a higher priority (check the attached project for better understanding).

If you would like to select a specific item, you will need to set the proper item value.

Hi Georgi,

How do I set the default value(not the 1st item) when the value from the model is not set? If the value from the model is set, I don't want the default value.

Thanks.

Hello Phillip,

In that case you should not use DropDownListFor. Use Html.Kendo().DropDownList and set the SelectedIndex option.
