I have to display information in datagrid some information is about 1000 record from the database (sqlserver) but to display this information c# take unless 4 sec to do that ….
And how work with the application when he don’t see the result immediately he continue to press the button and the application repeat the same function many time due to that (sad) …
I make a break point the time is between the end of the function and the display of window or datagrid … are that normal !!!!
If yes there’s any solution to display a part and when he use the scroll the datagrid add another part (like facebook) ??
The best solution is to implement paging. There is an article at http://www.eggheadcafe.com/tutorials/aspnet/8a2ea78b-f1e3-45b4-93ef-32b2d802ae17/wpf-datagrid-custom-paging-and-sorting.aspx that covers it.
Regardless, make sure you disable the button until the grid has finished displaying, and show a wait cursor as well. A user should never have to wonder if the application is working or failing.
