Iam trying to upload Employee timesheet excel which consists of 12000 - 15000 records in datagrid in Windows Forms using VB.net.
While Uploading I want to verify that Id column in excel is an Active employee Id with database, as data is huge, screen is getting white [ as in busy process ] as it does reading and binding.
1. How I can make screen while binding active, how to show as it is progressing without system getting hanged. ?
2. If I do first upload of excel it is taking 1 min time, then if I do verify for employee id then screen is getting white as in busy process ?
