Asp.net fileupload control postback problems
- by Spooky2010
using ASP.net, vs2008 C#.
Im using a FileUpload control on a webform. The uploading of a file (ie PDF dcouments) to a server directory works ok.
I have on the webform a "preview" button that the user can use to preview the PDF file after they have selected it via the Fileupload browse feature.
I do this by
if (this.FileUpload1.HasFile)
{
localURL = FileUpload1.PostedFile.FileName;
// use this to preview file. Other methods are restricted by local security requirements
Process.Start(localURL);
}
My problems is that after the button click Postback occurs the location of the selected file disappears from the textbox part of the Fileupload control.
How can i keep this info there, so the user does not have to browse again and instead can just click upload to upload the file.
Any help appreciated
thanks
