File validation does not work for me!

[elaheh]

Hi,
I have tried to use the codes are for validation in Asyncupload and uplod tools in these links:
http://demos.telerik.com/aspnet-ajax/upload/examples/async/validation/defaultcs.aspx?product=asyncupload
http://www.telerik.com/help/aspnet-ajax/upload-client-side-validation.html

But none of them works correcrtly! when I select a non-valid file (for example a pdf file which its extension is changed to jpg), it does not prevent uploading it.

this is all my code with Asyncupload:

<asp:Content ID="Content2" ContentPlaceHolderID="content2" Runat="Server">
<script type="text/javascript">
      //<![CDATA[
        function validationFailed(sender, eventArgs) {
            $(".ErrorHolder").append("<p>Validation failed for '" + eventArgs.get_fileName() + "'.</p>").fadeIn("slow");
        }
      //]]>
    </script>
<telerik:RadStyleSheetManager ID="RadStyleSheetManager1" runat="server">
    </telerik:RadStyleSheetManager>
    <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
        <Scripts>
            <asp:ScriptReference Assembly="Telerik.Web.UI"
                Name="Telerik.Web.UI.Common.Core.js">
            </asp:ScriptReference>

            <asp:ScriptReference Assembly="Telerik.Web.UI"
                Name="Telerik.Web.UI.Common.jQuery.js">
            </asp:ScriptReference>
            <asp:ScriptReference Assembly="Telerik.Web.UI"
                Name="Telerik.Web.UI.Common.jQueryInclude.js">
            </asp:ScriptReference>
        </Scripts>
    </telerik:RadScriptManager>
<telerik:RadButton ID="uploadbtn" runat="server" Text="upload"
        onclick="uploadbtn_Click">
    </telerik:RadButton>
    <telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server"
        AllowedFileExtensions="jpg,jpeg"
        TargetFolder="~/upload" OnClientValidationFailed="validationFailed"
        onfileuploaded="RadAsyncUpload1_FileUploaded" >
        <FileFilters>
        <telerik:FileFilter Description="Images(jpeg;jpg)" Extensions="jpeg,jpg" />
    </FileFilters>
    </telerik:RadAsyncUpload>

and in code behind for upload button:

protected void RadAsyncUpload1_FileUploaded(object sender, Telerik.Web.UI.FileUploadedEventArgs e)
    {
        Label fileName = new Label();
        fileName.Text = e.File.FileName;


        if (e.IsValid)
        {
            Response.Write(fileName + "::true");
        }
        else
        {
            Response.Write("false");
        }
    }

 Is there anything missing from me?

Hi Elaheh,

 
The validation is checking exactly the extension so if it is changed the expected behavior will be the file to be uploaded.

Hope this will explain the issue.

All the best,
