I have a radgridview which has a column whose value is set by an expression:
Me.StockGrid.Columns("Total").Expression = "(Qty) *" & CInt(Me.radtextbox1.Text)
I want to use the result of the expression to populate another column in the same grid.
Me.StockGrid.Columns("req").Expression = "(Total – Available)”
The result is always nothing although the total column value calculated by the first expression has a value and available has a value. Is this type of calculation valid?
