[Solved] Populating RadComboBox items

[Craig Fisher]

For a regular dropdown list I can do this:

<%

= Html.DropDownList("Status", (IEnumerable<SelectListItem>)ViewData["filterstatuses"])%>

Is there an equivalent way of loading the items in a RadComboBox?

Hello Craig Fisher,

No, there is no such method for RadComboBox. You should enumerate the data and create RadComboBoxItem objects on the fly. Of course you can create an extension method for this as well.

I'm trying to figure out how to do this without requiring code in the code-behind for the view.

The RadComboBox doesn't seem to support client side data binding though.

Can you offer some guidance on how to do this?

Do you have plans to provide an MVC implementation of RadComboBox?

Thanks.

Hello Craig Fisher,

You can do this in the view - no need to use codebehind:

<telerik:RadComboBox runat="server" id="RadComboBox1" />

<%
       foreach(SelectListItem item in ((IEnumerable<SelectListItem>)ViewData["something"]))
       {
              RadComboBox1.Items.Add(new RadComboBoxItem
              {
                    Text = item.Text,
                    Value = item.Value
              });
       }
%>

You can also add items with JavaScript as shown here.

We have a combobox component logged for implementation. You can vote for it here.

Thanks Atanas.
I just tried that code and the combox box is being rendered with no items.

 

(I gave my vote for the MVC combo box)

Hi Craig Fisher,

I am sorry - the population code must come before the declaration:

<%
       foreach(SelectListItem item in ((IEnumerable<SelectListItem>)ViewData["something"]))
       {
              RadComboBox1.Items.Add(new RadComboBoxItem
              {
                    Text = item.Text,
                    Value = item.Value
              });
       }
%>
<telerik:RadComboBox runat="server" id="RadComboBox1" />

I am sending you a sample project for your reference.
