<telerik:RadComboBox ID="ddlMyCombo" DataTextField="dev" DataValueField="devid" AllowCustomText="false" runat="server" Filter="StartsWith" ExpandDirection="Down" />
user should not be able to type in custom text in the ComboBox. I set the allowcustomtext property to false but it did not work.
when user types in custom text and the form is saved, the combobox selected value is -1.
please help with a solution to this.
