I have upgraded a project from VS2005 to VS2010. The application has been in use for several years. After the upgrade the DataGridView gives the error below on any data that contains a time column. From a still working version of the app, here is part of the grid showing the time data.
Does anyone know what is wrong with this format, or why I have an error since the upgrade?
I should also mention that the project was updated from .Net 2.0 to .Net 4.0.
I found the data for the time column. Here are the first few rows
- time {long[854]} long[]
[0] 634980383460000000 long
[1] 634980383710000000 long
[2] 634980384400000000 long
