There are many posts for this exact question. This is obviously homework.

You might want to look into why the page is taking so long, instead of a hacky workaround. Nice school you're going to.

People here frown upon doing homework for others. You should NEVER change the cursor to an hourglass through postbacks. It's a horrible practice.

If you know how to do it, then call the javascript function when it starts loading data.

Event firing problems

Hey

I have a problem with a page in a site i am developing. Basically this page will not perform server side events such as button click.

I have already checked the event wireup code and ran aspnet_regiis -i, aspnet_regiis -c.

Is there any thing else i may be missing?

Thanks.

Silly question, but have you defined an event handler? I can't imagine not being able to fire an event with a server side control... and it's a button, right? Confused | :confused:

Hi
I have a data table with around 10 millions of row, currently it is shown throught a datagrid with previous next paging option and sorting. When this data table is loaded in code for grid, it takes around 400 mb and if there are multiple sessions whole application can go up to around 2 GB, currently data table is stored in session b/c sorting requires table. if i dont store it in session then every sort takes huge time to get data from database. what is the way around.
I looked at a sample of caching but i think if i m storing 400mb of data table into it most of the time it will drop it. what can be the way around?

Regards
Shajeel

Create a paging procedure of your own.... Loading for example 100 rows max per page, in stead of loading the entire rows collection at once..

i m using asp.net datagrid with its paging. there are only 20 rows per page and previous next to move from 1 to onwards, problem is when i load whole data in data table memory of aspnet_wp process shoots. i want to keep the table so that when sorting i dont have to get data from database.

It's not a memory problem. It's a programming problem. Don't retrieve 10 million rows at one time.

That's exactly what I said... load the rows required to display on the current page, not more, not less...

It's possible that it is a problem with temporary files. Check the settings for temporary files in the browser. The default setting is that it uses a certain percentage of the disk space, which may be much more than it can handle. Set the limit to a reasonable value, like 50 MB.
