Question

I have a Windows form app. I get data based on a row position in a DataTable. I have a TotalCount variable and a CurrentPos variable. The button next should get the next row and the button previous should get the previous. These buttons should be enabled/disabled when there is data available.

My brain is much can you provide the logic

Answer 1

Is it not a simple

m_NextButton.Enabled =  CurrentPos < (TotalCount - 1) ; m_PreviousButton.Enabled = CurrentPos > 0; 

You need to call this when you

1. Add to your DataTable
2. Change Your Selection
3. Remove from your datatable
