Convert DataBinder.Eval

Question

User-604637336 posted

Hello, 

 If (DataBinder.Eval(e.Item.DataItem, "value") <> DBNull.Value) Then

      some conversion        

  End If

Operator '<>' is not defined for types 'Object' and 'System.DBNull' 

Could you give me any solution with this ?

Thanks

I am not a vb guy but i suggest you if it isn't working than you can compare like

If Not String.IsNullOrEmpty(Convert.ToString(DataBinder.Eval(e.Item.DataItem, "value"))) Then

End If

Regards.

You can use IIf for better performace, See:

 IIf(IsDBNull(DataBinder.Eval(e.Item.DataItem, "value")) OrElse _
            String.IsNullOrEmpty(DataBinder.Eval(e.Item.DataItem, "value")), "", "some(Conversion)")
