Hi,

How to add the Require field validation in dropDownCheckBoxes ...?

This is my code

XML
<asp:dropDownCheckBoxes ID="ddllanguage" runat="server" xmlns:asp="#unknown"  onchange="onSelectionChange()"
                AddJQueryReference="True" UseButtons="false" UseSelectAllNode="false" ClientIDMode="Static">
                <Style SelectBoxWidth="200" dropDownBoxBoxWidth="200" dropDownBoxBoxHeight="130" />
                <Texts SelectBoxCaption="-Select-" />
            </asp:dropDownCheckBoxes>
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server"  ControlToValidate="ddllanguage"
                          ErrorMessage="*" ToolTip="Language is required"
                         ValidationGroup="Veterinary" InitialValue="-Select-"
                        ></asp:RequiredFieldValidator>


When i run the application i am getting this error "Control 'ddllanguage' referenced by the ControlToValidate property of 'RequiredFieldValidator2' cannot be validated."

Change InitialValue property with your value field i.e. "0" or "-1" whatever your value for "-Select-".

i think there is minor mistake. you have not wrapped control to validate in "". It should be
ControlToValidate="ddllanguage"
