I have used expression in the Listbox to eliminate the null values. it is working fine and displaying the correct values. But the problem is the associated values are not showing in order. It is showing in mixed way like showing the associated values,Non associated values and again associated values.
GO to the Sort Tab in The list Box and Choose/Tick the Text Check Box or if there is Numeric Value choose Numeric or you can choose Expresion to define the numeric Sort Value for your Field Expresion.I meant select the same code of field Expresio and change values to Numeric as you want.
