I'm using five FileUpload controls on a single web form. Besides allowing the user to upload a file I also am collecting user data. Problem I run into is during the server side validation if any of the user data is invalid on a post back when content it redisplayed the FileUpload controls loose the client url that was selected when browsing. How can I keep that path or set the pathing on the control so they do not have to keep rebrowsing for the files on data validation errors? Right now breaking up the two form sets user data and file upload into two pages is being frowned upon and requirments would like it to be on all one page.

i am using Fileupload and 3 dropdown control in update panel, 3 dropdown will be post back on dropdown selected index change event (i.e like Country,states and city... get the value from db as per country,states and city)

While postback the filename path is gone from the file upload control(as expected/ or Default property).
I am converting the file to byte array, to store in the database from file upload control.
How can i retain the value or Is there any way to solve this issue.
Is there any ajax control for file upload or any free controls which retain the value after postback also...?
Or it is possible to set the value to file upload control during postback ?
I have "n" <tables></tables> on my page and each <table> has One(1) <asp:CheckBox.. Enable ='true"/> and "x" <asp:TextBox Enabled="false"..>. Each Table looks as follows
[Code]....
When I click checkbox, it calls javascript function and enables textboxes (I have added onclick attribute to checkbox). Page also has <asp:Button ...Text="Submit"/> whcih actually grabs the data from the textboxes on the page and send it to the databse. Here is the Onclick event of the <asp"button../>
[Code]....
If the exception is thrown , textBoxes are not reset but on postback textboxes appear as disabled (values are not reset)
So here is what happening on postback when exception is thrown
1) Values are not reset (that is what want)
2) Texboxes appear as Disabled (that is what I don't want on exception, REMEMBER I enable textBoxes using client side script)
How can I keep the textboxes enabled = "true"
I have a system that has several large objects that need to be built and populated each and every time, and these objects may be accessed quite often as well. As a strategy, caching would not be that good for me because there are potentially thousands of these objects which are fairly large. So I propose to serialize the objects to the file system and then deserialize it when I need those objects again. I have several classes that need this serialization functionality.
These objects change as well, so on the next access I check if there were any changes and then I grab only the changes and edit the object, and then reserialize the object.
My question is what is the best way to do this, since I have several classes ..
Here is the sample code am trying.
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true" />
<div>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="conditional">
<Triggers>
<asp:PostBackTrigger ControlID="Button1" />

This upload is working. But why the page is getting refreshed? this is not partial post back and instead it 's full post back. i have read the articles for the fileuplaod with issue inside the update panel. is there any way to achieve this asynchronous upload on button click?
I don't want to use the Ajaxtoolkit Asyncupload because that will upload (Ref : [URL] ....] the moment when we seelct the file itself which i don't want to do that. i need to do on the button click event.
I have a abc.aspx page having some control like (drop downs, text boxes), i am filling a grid based on selected items in the drop downs and date selected from the ajax calender extender control attached to the from data and to date text boxes.
Inside grid there is a link which redirects to bcd.aspx, this page (bcd.aspx) is having a back button to redirect abc.aspx.
Now what i want is, abc.aspx should main its state like grid, drop downs and text boxes should be shown as it was earlier, i.e. all should have same values as it was at the time of redirecting to bcd.aspx.
Yes, there is a way to maintain the state by passing all values from query string and than get all values back and rebind all controls. But i don't want to go this way because i will have pass so many values in query string.
