CS code corresponding to ASPX
Protected void Page_Load (object sender, EventArgs e)
{
// Bind the upload client javascript event
This. BtnUpload. OnClientClick = this. WebUploadProgressBarControl. GetUploadClick_Javascript;
// Bind the upload cancel client javascript event
This. hyCancel. NavigateUrl = "javascript:" this. WebUploadProgressBarControl. GetUploadCancelClick_Javascript;
}
Protected void BtnUpload_Click (object sender, EventArgs e)
{
// Upload a file
This. WebUploadProgressBarControl. SaveUploadFiles ();
}
</Example>
<Remarks> you must set a port or virtual directory under the IIS Site to pass the test.
