    I am using a ribbonbar and under my view tab I have a Theme Section with a radDropDownListElement.  I loaded it with all the Themes I want to allow, but when I run the application the following occurs.
    the default value is blank, I would like it to show my current setting.
    When I click on the dropdown all the themes I entered are visable.
    When I select one the value changes visually on the screen to what is selected.
    I have put breaks in the code below, but the application never stops.


     

     

    private void radDropDownListElement1_SelectedValueChanged(object sender, EventArgs e)

     

     

    {

     

     

        ThemeResolutionService.ApplicationThemeName = radDropDownListElement1.Name;

     

    }

     

     

    private void radDropDownListElement1_Click(object sender, EventArgs e)

     

    {

     

     

        ThemeResolutionService.ApplicationThemeName = radDropDownListElement1.Name;

     

    }


    So the long and the short is how do I capture what is selected to get the theme to change for the user.

    Thanks

    Hello Stephan,

    Thank you for writing.

    Here is a small example that provides the desired functionality (assuming that you have the themes already loaded):
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
     
            radDropDownListElement1.Items.Add("TelerikMetroBlue");
            radDropDownListElement1.Items.Add("Office2007Black");
            radDropDownListElement1.Items.Add("Office2010Silver");
            radDropDownListElement1.Items.Add("ControlDefault");
            radDropDownListElement1.SelectedIndex = radDropDownListElement1.FindString("ControlDefault");
            radDropDownListElement1.SelectedIndexChanged += new Telerik.WinControls.UI.Data.PositionChangedEventHandler(radDropDownListElement1_SelectedIndexChanged);
        }
     
        void radDropDownListElement1_SelectedIndexChanged(object sender, Telerik.WinControls.UI.Data.PositionChangedEventArgs e)
        {
            ThemeResolutionService.ApplicationThemeName = radDropDownListElement1.SelectedText;
        }
    }

    Let me know if you need further assistance with this case.

    Kind regards,
