Datagridview cellvalidating not working Chat for free without signing up hot sexy girls
If you are implementing virtual mode in order to work efficiently with large amounts of data, you will also want to ensure that you are working efficiently with the Data Grid View control itself.
For more information about the efficient use of cell styles, automatic sizing, selections, and row sharing, see Best Practices for Scaling the Windows Forms Data Grid View Control.
This scenario is particularly useful when working with large amounts of data over a slow network connection or with client machines that have a limited amount of RAM or storage space.
Could you strip only a part of your code and send it as a small example to allow us looking into this issue?
If I understand you right, you have found a work-around for you case.
However, I would still like to investigate the issue further.
Therefore, when you enable sorting in mixed mode, you must manage the unbound data in a local cache and implement virtual mode to let the Data Grid View control interact with it. If bound mode does not meet your performance needs, you can manage all your data in a custom cache through virtual-mode event handlers.
For more information about using virtual mode to maintain the values in unbound columns, see the examples in the Data Grid View Check Box Column. For example, you can use virtual mode to implement a just-in-time data loading mechanism that retrieves only as much data from a networked database as is necessary for optimal performance.
