Hi,

I am using RadControls for ASP.NET AJAX Q1 2010 SP1 in my current project.

Can you please tell me how to deselect the items in a ComboBox after it is initially loaded?

I tried to do it by setting SelectedIndex to -1 as follows but it didn't work.

protected void Page_Load(object sender, EventArgs e) 
    if (!IsPostBack) 
    { 
        this.rcbCategory.DataSource = PublisherServer.Categories(); 
        this.rcbCategory.DataTextField = "Name"
        this.rcbCategory.DataBind(); 
        this.rcbCategory.SelectedIndex = -1; 
    } 

Regards,
Herman Gouw

Hello,


Have you tried "ClearSelection()" method which clears out the list selection and sets the Selected property of all items to false.

Clear RadComboBox


Thanks,
Princy.

Hello Herman Gouw,

I suppose that your RadComboBox is read-only and in this case there will be always a selected item in it.

However you can add a “default” empty item to be displayed in the RadComboBox input.
In this way you will be able to "deselect" the initially selected item – you can find more details about this approach here.

If the issue persists, could you please explain your implementation in more details and send us a sample code? Thank you in advance.

Best wishes,
