How to deselect the items in a ComboBox

[Herman Gouw]

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

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,
