Data Scrolling

Im using VB6.0 and now starting to upgrade to VB.NET.

The problem is, i made a VB.NET program which only displays a database thru datagrid and textboxes. im successful with that but the problem is whenever i scroll through the data backward or going back to previous i have this error appearing:


An unhandled exception of type 'System.NullReferenceException' occurred in system.windows.forms.dll

Additional information: Object reference not set to an instance of an object.


can anyone help me how to get rid of that error, please.

Post the code you are having problem with.

this is the code for the Movefirst and MovePrevious:

Private Sub btnmovefirst_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnmovefirst.Click

mycursor.Position = 0
txtvalues()

End Sub




Private Sub btnmoveprevious_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnmoveprevious.Click

mycursor.Position = mycursor.Position - 1
txtvalues()

End Sub
