Processing or wait control

[Vish]

Hi,

Is there a processing or wait control in .NET that i can display to the user
when large amounts of data are loaded from the database. Since i cant use the
progress bar since i dont know how much data is loaded from the database.

Thank you,
Vish

You can use a poor-man's progress bar that cycles, when it gets to the
end start over. At least this way the user knows the system is still
going. The other option would be to make a call to the DB to get the
number of records, then use a datareader to load the data from the
database. This way you can incriment the progress bar in your
datareader loop and it will be acturate.

The other issue you are going to have is the responsiveness of the UI
during a CPU intensive action. The way to fix this is to load the data
in a worker thread.

Hope it helps

Hello vish,

You can't know how much data is in DB without pre-request, that is not good.
The best approach is do not use bars for this, just smth special to note
that work in process (just box with time cursor, or any other solution)

Hi,

Thanks everybody for the suggestions. I have seen UI where a dotted circle
keeps spinning like in MS SQL Server 2005. I think those will serve my
purpose. Are any of those controls packaged with .NET 2.0 so that i can use
them.

Thank You,
Vish
