<div class="content wysiwyg-content">
I have a form with a file input that allows users to browse local harddrive for images to upload.<br />
<br />
On the same form I have an autopostback dropdownlist for categories, but when the event fires all the server controls maintain viewstate but the file inputs are cleared?<br />
<br />
I tried adding runat=server enable viewstate = true<br />
but that does not work.<br />
<br />
I also set a hidden label with the file value, but I am unable to set the inputfile.value with the lable.text.<br />
<br />
Does anyone have a solution. I really want the inputs to maintain their values, without having extra labels and extra work<br />
<br />
Thanks<br />

how to enableviewstate on an input type=file

Active Server Pages (ASP) is Microsoft’s first server-side engine for dynamic web pages. ASP’s support of the Component Object Model (COM) enables it to access and use compiled libraries such as DLLs. It has been superseded by ASP.NET, but will be supported by Internet Information Services (IIS) through at least 2022.
