Hello All,

i'm migrating asp.net application to be compatible with IE10 and old asp custom vaildation(s)
doesn't work, thee's no call to the clientvalidationfunction specified in the custome validator here's the code

JavaScript

function ProductsReqValidationManageApp(source, args) {
         alert(args);
         alert(source);
         if (document.getElementById("trmanageappproducts").style.visibility == 'visible') {
             var ddl_ProductsCheckBool = document.getElementById("ddl_productsmanageapp").value;

             if (ddl_ProductsCheckBool != "0" && ddl_ProductsCheckBool != "" && ddl_ProductsCheckBool != null) {
                 args.IsValid = true;
                 return;
             }
             else {
                 args.IsValid = false;
                 return;
             }
         }
     }

and here's the custom vaildator tag :

ASP.NET

<asp:CustomValidator ID="CustomValidator1" ControlToValidate="ddl_productsmanageapp" runat="server"
                                                      ClientValidationFunction="ProductsReqValidationManageApp" ErrorMessage="Required Field" Display="Dynamic" Font-Bold="True"></asp:CustomValidator>

thanks in advance,

Such issues are mostly related to the .NET framework and browser definition files. .NET does not recognise the browser definition string correctly and handle IE 10, IE 11 versions as unknown browsers and hence the issue.

If you are using .NET framework 4.0, the issues will be fixed by simply installing .NET framework 4.5. You will not need to make any changes to your application.
