How to check that at least one item is selected

[Jesper]

Hi,
how to check that at least one item is selected in a RadComboBox? My RadComboBox allows just single selection and I want to check that user has selected one item which is needed for next/related user input control (RadListBox) will be loaded with data (from code behind). Meaning I will check that at least one item is selected from code behind method RadComboBox_SelectedIndexChanged and if one item is checked load data into next/related RadListBox.

Why isn't there a method RadComboBox.SelectedItems.Count as there is for example RadListBox?

I have EmptyMessage set to '--- Select ---' in RadComboBox. Can I use this in some way?

Rgds,
Jesper

Hello Jesper,

You can try the following for getting the count of selected items.

C#:

  protected void RadComboBox1_SelectedIndexChanged(object sender, Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs e)
{
 int count = RadComboBox1.SelectedValue.Length;
}

Thanks,
Princy.
