RadAsyncUpload OnClientValidationFailed无缘无故触发

Question

有人在Telerik forum中问了这个问题。

我有一个RadAsyncUpload，即使文件在大小限制内，也会调用OnClientValidationFailed函数，但文件大小错误。

标记

<telerik:RadAsyncUpload runat="server" ID="fUploader" PostbackTriggers="btnSendEmail,btnSaveDraft" OnClientValidationFailed="fileUploadValidationFailed"></telerik:RadAsyncUpload>

服务器端

fUploader.TargetFolder = uploadPath;

fUploader.AllowedFileExtensions = New String（）{“ .jpg”，“ .png”，“ .gif”，“ .jpeg”，“ .bmp”，“ .tiff”，“ .pdf”，“ .gpx”，“ *。tcx”}

fUploader.MaxFileSize = 2500000

javascript

function fileUploadValidationFailed(sender, args) {
var fileExtention = args.get_fileName().substring(args.get_fileName().lastIndexOf('.') + 1, args.get_fileName().length);
if (args.get_fileName().lastIndexOf('.') != -1) {//this checks if the extension is correct
    if (sender.get_allowedFileExtensions().indexOf(fileExtention.toLowerCase()) == -1) {
        alert("File type selected is not allowed.  Valid file types are .jpg, .png, .gif, .jpeg, .bmp, .tiff, .pdf, .gpx, .tcx");
    }
    else {
        alert("File too large.  Max file size 2 MB.");
    }
}
else {
    alert("File type selected is not allowed.  Valid file types are .jpg, .png, .gif, .jpeg, .bmp, .tiff, .pdf, .gpx, .tcx");
}}

web.config

<system.web>
    <httpRuntime maxRequestLength="8192"/>
