Combobox data bindng using SharePoint web service.

[Kaustubh Wadi]

Hello Telerik Team,

I am using Silverlight Radcombobox in one of my SharePoint application. I am able to bind sharepoiint list items to combo box using following approach.

XNamespace ns = "#RowsetSchema";
            var query = from x in e.Result.Descendants()
                        where x.Name == ns + "row"
                        select x.Attribute("ows_Title").Value.Split(',')[0];
            combobox.ItemsSource = query;

Now what i want is, the display text for combo box should be from Title column of sharePoint list,
But i want the ID of selected Title in code behind file.
I am getting 'title' from combobox.selectedvalue statement. How can i get ID using combobox.selectedvalue statement?
Can I set selectedvaluePath property to sharepoint list's ID column in code behind file.?

Please guide me.

Many Thanks,
Kaustubh Wadi

Hello Kaustubh,

As far as I understand, you want to display the Title property in RadComboBox, but use the ID property. For this to happen you need to bind the control to a collection of objects that have Title and ID properties, something like this:
public class DataItem
{
    public int ID { get; set; }
    public string Title { get; set; }
}

// You should modify your Linq query and use it here instead of the new list
combobox.ItemsSource = new List<DataItem>();
combobox.DisplayMemberPath = "Title";
combobox.SelectedValuePath = "ID";

...

var id = combobox.SelectedValue; // The ID of the selected DataItem

I hope this helps.

All the best,
