I used the explanation from this and it fixed my problem: https://www.telerik.com/forums/radcheckeddropdownlist-textbox-content

private void radCheckedDropDownList1_LostFocus(object sender, EventArgs e)
{
     string delimiter = this.radCheckedDropDownList1.CheckedDropDownListElement.AutoCompleteEditableAreaElement.AutoCompleteTextBox.Delimiter;
     StringBuilder sb = new StringBuilder();
     foreach (RadListDataItem item in this.radCheckedDropDownList1.CheckedItems)
     {
         sb.Append(item.Text + delimiter);
     }
     this.radCheckedDropDownList1.Text = sb.ToString();                              
}
