Hi Tin,

I suppose that you want to allow only some file extensions for uploaded files. The AllowedFileExtensions property lists the valid file extensions for uploaded files. When the AllowedFileExtensions property is set, RadUpload automatically validates the extensions of selected files, moving any files with disallowed extensions to the InvalidFiles collection.

ASPX:

<telerik:RadUpload id="RadUpload1" runat="server" allowedfileextensions=".zip,.jpg,.jpeg" />

Hope this helps.

Thanks,
Princy.

Hi Tin,

Try the following code snippet.

ASPX:

<telerik:RadUpload ID="RadUpload1" runat="server" onvalidatingfile="RadUpload1_ValidatingFile"  >
</telerik:RadUpload>

C#:

protected void RadUpload1_ValidatingFile(object sender, Telerik.Web.UI.Upload.ValidateFileEventArgs e)
    {
        UploadedFile file = e.UploadedFile;
        if( file.GetExtension() ==".gif")//can give the invalid file extensions
           {
               Response.Write("Invalid file");
               e.IsValid = false;
           }
    }

Hope this helps.

Thanks,
Princy.
