Hello.
I'm developing an ASP.NET application with C# and Visual Studio 2008 SP1. I'm using WebForms.
I have an ASPX page with two UpdatePanels, one on the left that holds a TreeView and other on the right where I load dynamically user controls.
One user control, that I used on right panel, has a FileUpload control and a button to save that file on server. The ascx code to save control is:
<asp:UpdatePanel runat='server' RenderMode='Inline'
UpdateMode='Conditional'>
<ContentTemplate>
<asp:Button runat='server' Text='Guardar'
CssClass='button' />
</ContentTemplate>
<Triggers>
<asp:PostBackTrigger ControlID='Save' />
</Triggers>
</asp:UpdatePanel>
Asp.net Upload File Hasfile Always False
I make a full postback to upload the file to the server and save it to database. But I always getting False on FileUpload.HasFile.
I problem is the right UpdatePanel. I need it to load dynamically the user controls. This panel has three UpdatePanels to load the three user controls that I use.
Maybe I can use an Async File Uploader or delete the right Update Panel and do a full postback to load controls dynamically.
Any advice?
Thank you.
I am creating a visual web-part for my SharePoint 2013 environment. I am using asp:FileUpload control(fuBrowseXMLFile) in this web-part for uploading files to a document library. I have a button Save to initiate the process of uploading the file.
After deploying the code, i try to run it in Debug mode. I found that after clicking the Save button, when the debugger hits the following line of code,
fuBrowseXMLFile.HasFile returns FALSE. Whereas the file is selected in the control.
While searching for a solution, I came across lot of articles. But, unfortunately most of them talk with reference to UpdatePanel. I am not using UpdatePanel here.
I understand that it has to do something with Postback. But, I am not sure what would exactly resolve my problem.

Inorder to retain the selection during PostBack you should enable the view state property as below
