Is there some way to display a progress or wait message while data is loading into a grid? I saw that there is a UseWaitCursor, but that did not seem to work as it always used the wait cursor even if data was not loading.
Thanks.
Hi,
I am using a progress animation to visualize the loading progress. It looks like the progress control the SQL server 2005 is using. When the loading was started, the control will be shown (RotatingProgress.Show() for example). And when the BackgroundWorker raise the Completed event, the control will be hidden.
If you using a DataTable as DataSource for the grid I have some code using the DataReader to load rows just in time into the grid. This code will also using a BackgroundWorker. I have the code not here at work, but I can put it here today.
Kind regards,
Ralf

Now you have got me. I have seen it done, but i dont really know quite how they did it.
Should it not be possible to run the fill for your dataset in the Background worker, and then use a loop to run the ReportProgress method, also setting the progress on your ProgressBar?
I dont know...I am just playing with ideas here.
Anyone else got any ideas?
BackgroundWorker only raise event ProgressChanged when you call method ReportProgress(). Could you show me how to calculate percent complete of loading data into grid and grid render to display.
My application have data about 20.000 - 50.000, so I need this very much.
Thanks!
