hey i have a table under the repeater like shown below in the code. Now my problem is there showing the empty rows too along with the data from that table value "TotalAmount". So i am wondering if I could be able to put the condition under that table. some thing like if value equals null, delete the table cell or else show the table cell kind of thing. Is there any way I can do this?
<asp:Repeater ID="rptTotAmount" runat="server">
<ItemTemplate>
<div style="page-break-after:always;">
<asp:Table ID="tblItemListt" runat="server" Font-Size="8%">
<asp:TableRow>
<asp:TableCell HorizontalAlign="Right"><%# DataBinder.Eval(Container.DataItem, "TotalAmount", "Total: {0:c}")%></asp:TableCell>
</asp:TableRow>
</asp:Table>
</div>
</ItemTemplate>
</asp:Repeater>

I'm not sure if I understand. You have a table with one cell in each row and want to hide the cell when it is empty? In that case, why not just remove the empty rows from the datasource before binding?

Then how can it not be the database? How are you joining the tables? Are you using an INNER JOIN or an OUTER JOIN? No matter, you can still filter out the empty rows before binding to the repeater.

OK, lets start from the beginning. Where is the data coming from? What nested repeaters? You have only shown one.

ok I need to page break once i get my TotalAmount. I had used style=page-break-after:always property under the nested repeater as shown. Its working for part of data and for part of data, its not working. Page break is happening for some part and for some part there is no page break. This is my problem. I need page break throughout my data.

This isn't even close to what originally asked. First you wanted to remove empty cells now you want page breaks in a PDF?

Sorry also when i am showing the total amount, based on the second repeaters items number, the correspoding empty lines been added after the total amount. I need to delete those empty cells too.

Old joke from Steve Martin, or Steve Artin.
"I have some hostages, and they are tied up in a sack at the top of a flag pole. I'm going to blow them up at midnight, unless I get these three demands: ONE! I want a million dollars! TWO: I want a getaway car waiting for me! and THREE: I want the letter M stricken from the English language. See, you have to make one crazy demand, so if they catch you, you can plead insanity. Heh, heh, getaway car."

Common sense is admitting there is cause and effect and that you can exert some control over what you understand.

So if I understood your explanation further down the thread correctly you missed an important addition:

Getting a million dollars is easy. Create a .99 iPhone App, there are at least 2 million (Steve Jobs needs his cut) stupid iPhone users who will buy it.

Hi,
I have a web form that allows users to upload files while opening a ticket in our system.
The upload is done using the "ajax control toolkit" asyncFileUpload.
Currently, the files are saved to a temp directory and will only be save to the permanent location when the user hits the "commit" button.
I would like to be able to get rid of temp files that are no longer relevant (e.g. The user leaves the page open for a month without posting the form).
What would be the best way to not keep temp files forever.
Maybe keeping them files in the session?
Maybe keeping them in the viewstate?
I could add some JS to the page with a timeout and add some code that runs when the user leaves the page. But these ideas are client side solutions. I wouldn't want someone to tamper with the code and leave me rubbish on my system.
Any other idea?
Thanks,
Summerbulb

Service/scheduled task on the server that will delete files older than X?
|
|
|
|
|
How about placing the cleanup code in the same area as where the user is allowed to upload his files temporarily.
Something like:
1) User wants to upload file.
2) check for any files that are older than "X" days and delete them
3) Continue with the upload logic
This eliminates the need for creating a separate task that would run as a service or scheduled task.
Just a thought.
