How to calculate one text box to another text tab index in c#.net?
If you mean, how can you display a value in another text box based on entry in a different text box, you can use the .Text property of the target text box and the .TextChanged property on the source text box:





Sub TBSource_textChanged(Object Sender, EventArgs E)


String strOutput;


strOutput = tbSource.Text.Len();


TBDest.Text = strOutput;


End Sub





If you mean, you want a different text box to take focus on a given text box's text being changed, you again use .Textchanged event from the source and the Focus event on the destination (Focus is new in .NET):





Sub TBSource_textChanged(Object Sender, EventArgs E)


TBDest.Focus();


End Sub
