Display issues

[Sylvain]

Hello

I'm having issues with a combobox trying to reproduce the validation groups example.
However my issues have nothing to do with the validations groups but only with the display of the RadComboBoxItem (cf. attached screenshot)
 
Here is my ASPX code :

<label>Project : </label> <telerik:RadComboBox ID="ComboBoxProjects" Width="180px" runat="server" />

And my C# code :

protected void Page_Load(object sender, EventArgs e)
 {
        if (!IsPostBack)
        {
            this.ComboBoxProjects.Items.Add(new RadComboBoxItem("- Search in -"));
            this.ComboBoxProjects.Items.Add(new RadComboBoxItem("All Platforms"));
            this.ComboBoxProjects.Items.Add(new RadComboBoxItem("ASP.NET"));
            this.ComboBoxProjects.Items.Add(new RadComboBoxItem("WinForms"));
            this.ComboBoxProjects.Items.Add(new RadComboBoxItem("Silverlight"));
            this.ComboBoxProjects.Items.Add(new RadComboBoxItem("WPF"));
            this.ComboBoxProjects.Items.Add(new RadComboBoxItem("Reporting"));
         }
}

Thank you for your help, I start to be kind of desperate here T_T

It seems to come from my CSS file, since when I remove it everything works.
But I can't put my finger on the source of the problem ...

Found it ...
It was default css properties of "ul" and "li" that were messing with the controls.
Everything works now.
