I am using AjaxFileUploader to upload multiple files in my ASP.net project.

I want to validate RequiredFieldValidator on It, Means at least one file must be Upload before submit Form.

My Code is:

XML

<ajaxToolkit:AjaxFileUpload
    id="ajaxUpload1" ThrobberID="MyThrobber1" MaximumNumberOfFiles="5" runat="server" AllowedFileTypes="jpg,png"></ajaxToolkit:AjaxFileUpload>

How can validate this control as Requiredfiled, because Simple RequiredFieldValidator does not work on it.

is there any other solution ???

Apply Below given Custom Validator on file Upload Control

<asp:CustomValidator CssClass="asterisk" ID="CustomValidator1" runat="server" Display="Dynamic" ControlToValidate="FileUploadCtrl" ErrorMessage="Please browse file to Upload"        SetFocusOnError="true" ValidateEmptyText="True" ValidationGroup="ValGrp"
                                        ClientValidationFunction="CheckFile">
</asp:CustomValidator>

Write below javascript
  function CheckFile(source, arguments) {

        var path = document.getElementById('<%= FileUploadCtrl.ClientID %>').value;
