[Solved] DropDownListFor SelectedIndex

[cp]

Hi,
I'm having a little trouble with a DropDownListFor where I'm not able to change the selected item. I've tried both selecting an item inside the BindTo method as well as using SelectedIndex and neither seem to change the selection.

This is the code I'm using:

<%= Html.Telerik().DropDownListFor(model => model.SomeObject.SomeProperty)
              .HtmlAttributes(new { style = "width: 160px;" })
              .BindTo(new SelectList(Model.Statuses, "Text", "Value", Model.SomeObject.SomeProperty))
%>

If I change it to a DropDownList the selected item changes as expected.

Any help is appreciated.

Thanks,

Hello Claudiu,

DropDownList component searches for pair <key-value> in the ViewData. The key should be same as the component Name. DDL will try to find DropDownItem which has same value and will select it. If the DDL succeed with this actions then the SelectedIndex is ignored. If you need to select item using SelectedIndex method, then component should not be named as a key in the ViewData dictionary. 

If the problem still exists I will suggest you to send us a simple project which reproduces the depicted issue. Thus I will be able to observe the problem locally and advice you further.

Thanks Georgi.

I will see if I can pull out some of the code to duplicate the problem I'm having (unless you already have a sample with a dropdownlistfor inside an ajax.beginform). I have a few other helpers in that partial view and they all work fine, I'm just not able to get the selected item to display inside the dropdownlist on postback. The rebinding works as well since I modified the list on postback and I'm able to see the new values.

Hello Claudiu,

I can't find any problem with a DropDownListFor inside an Ajax.BeginForm.

I have attached a simple project which show how to preselect item inside an Ajax.BeginForm.

If this does not help I would ask you to provide a sample application which we can test locally.

Kind regards,
