Hello Akhilesh,

First of all, I would like to ask you whether you use the classic RadUpload or you use RadUpload "Prometheus" as you say that you are using RadUpload v2.3.2 which is a version of the classic RadUpload while this is a forum thread about RadUpload "Prometheus", although in the current case there is no matter what is the RadUpload you use.

Below I suggest you a workaround for your scenario. The suggested workaround does not depend on whether you use the classic RadUpload or you use RadUpload "Prometheus".

ASPX/ASCX:

<telerik:radupload id="RadUpload1" runat="server" allowedfileextensions=".jpg,.jpeg" onvalidatingfile="ValidateFile" targetfolder="~/Files"/>
<asp:button id="Button1" runat="server" text="Submit" />

Code-behind:

protected void ValidateFile(object sender, Telerik.Web.UI.Upload.ValidateFileEventArgs e)
{
    string[] allowedExtensions = RadUpload1.AllowedFileExtensions;
    bool allowedExtensionFlag = false;
    for (int i = 0; i < allowedExtensions.Length; i++)
    {

        if (e.UploadedFile.GetExtension() == allowedExtensions[i])
        {
            allowedExtensionFlag = true;
        }
    }
    if (!allowedExtensionFlag)
    {
        string script = "alert('Invalid files');";
        Page.ClientScript.RegisterStartupScript(this.GetType(), "ValidateFiles", script, true);
    }
}

You can feel free to modify the suggested code so that it serves your needs.

Please, let me know if you need further assistance.
