This sample demonstrates how to use the ASPxUploadControl, and how to pass a file name that was saved on the server to the client, by using the server-side and client-side FileUploadComplete events.
function OnUploadStart() {
btnUpload.SetText("Uploading...");
btnUpload.SetEnabled(false);
}
function OnUploadComplete(args) {
btnUpload.SetText("Upload");
btnUpload.SetEnabled(true);
lblFileName.SetText(args.callbackData);
}
<script runat="server">
protected void Page_Load(object sender, EventArgs e) {
}
protected void ASPxUploadControl1_FileUploadComplete(object sender,
DevExpress.Web.FileUploadCompleteEventArgs e) {
string fileName = e.UploadedFile.FileName;
e.CallbackData = fileName;
}
