VS 2010 File (Excel) Uploading And Processing
Sep 27, 2011
I come from MVC side, where these things make more sense (of course just because I know a bit about it) and my webforms are still sucky sucky.
I got a page where I want the user to upload a file (Excel).
Not too worried about the upload timing out, but after uploading this file will be processed (time & attendance data to be written to the database)
So what I'd like to happen is everything happen asynchronously with the page being updated as the file are being processed.
Also, I'm not sure.. won't I need excel on the server to have my code read the excel file?

I added a new report template from the Reporting section of the Installed Templates (rdlc extension). I have successfully created a connection and am retrieving data into textboxes that I have placed on the report. My problem is that I want to do a Test in the Expression template, but I cannot seem to do 'if else' statements. Can anybody give an example of how to perform conditional processing for a textbox on an rdlc page. i.e. The expression for just populating a textbox might be:
Code:
=First(Fields!Actioned.Value, "MyData")
What I want to be able to do is something like
Code:
if =First(Fields!Actioned.Value, "MyData") = "val1" then 23 else 25 end if
Coding for this control seem to take VB/VBA Style syntax.

I have a big excel file , and i want to upload it to server.
on upload_click , i have to do a processing which takes very long time,
because i am finding latitude and longitude from the google by reading that excel file.
and i wanted that when used click on CANCEL button the process should stop.
i have created a thread on upload_click and doing all this stuff in that thread .
when user clicks on CANCEL , i am aborting that thread.
but when user again tries to upload file , i am getting the error that file is in use .
to solve this problem i have to stop aspnet_wp.exe from task manager and have to try again .

I have a droplist, that I generate from an Excel file.
Code:
cmdExcel.Connection.Open()
dropdown1.DataSource = cmdExcel.ExecuteReader()
dropdown1.DataTextField = "BCName"
dropdown1.DataBind()
cmdExcel.Connection.Close()
I want to add two more options to the droplist:
dropdown1.Items.Add("Select")
dropdown1.Items.Add("All")
But if I do like this they are added after the items from the databind. I want the Select and All as the two first ones and then get the rest from the databind. How do I do that?

Input: - 3 excel files storing them into global temporary tables after reading cell by cell.
Requirement is to process inputs files and generate a single excel report.
After report gets exported, data in tables in should be deleted (i am using global temp tables for this).
But the problem is, two users are unable to generate report simultaneously.
Is this problem with global temporary tables?

I have a web page which I have created to allow users to upload excel file sheet and thus these sets of data will be inserted into the database. However, as I was testing out, I realized that if the excel file is too large (i.e. mulitple sheets, > 5 sheets) , the portal may not be able to handle the large amount of data and displayed error message like the connection is reset. I tried it with only less than 5 sheets it will be fine. Any idea if there are any codes or mechanism which could solve this problem?

I am debugging an ASP.Net C# application in Visual Studio 2010, the application is running and execution is currently stopped at a breakpoint. How can I stop the page execution without "Terminate All" or killing the debugging process altogether, similar to what would happen if an unhandled exception was thrown? The "Break All Cntl+Alt+Break" option is grayed out in the Debug menu.
I want to stop the app from running but not have to go through a compile/start again. EDIT: I want execution to stop, not break, so that the page finishes loading and I don't continue running the application from the breakpoint forward. I've looked through the Breakpoints panel, the Debug menu and have right clicked all over but still haven't found the right option.

I want to upload data from an Excel Sheet into my DB. Now my major requirement is, I do not know the header count in the files to be uploaded and they may vary, for example one file may have 3 headers while some may have 6. and I want data of both these files to go into a single DB. That is, I want to dynamically generate columns in my DB, and store these values. So how do I go about achieving this.

With the ajax file uploader, would it be possible to check the size of the image before uploading?Currently, it uploads the file to the server and then lets me know that it's bigger than the limit size.
