Can you show a larger block of code? It seems like something else is wrong after you add the computed property to the QueryFeatureOptions object.

So I think that 1 property is add but when I try to get the property values MG give me this error "OSGeo.MapGuide.MgObjectNotFoundException: The specified object was not found". I call my property with this name "thetooltip" and the property expression is: Concat ( 'Nome Sito: ' , Concat ( NOME_SITO , Concat ( '\nCodice Sito: ' , Concat ( SITENUMBER , Concat ( '\nSrambling Code: ' , SCRAMBLING_CODE ) ) ) ) ) I can't modify the featuresource because is used from another program Regards, Matteo So I'm guessing in your code you have something like: result=mgFeatQueryOptions.AddComputedProperty(computedPropAlias, computedProp); So what if you add a debug statement after it to do something like echo the following: Response.Write("Computed Property index: " + result.ToString()); An alternative to trying to do this in code might be to edit the feature source and add the computed property there. Create your layer using the extended feature class and in your code you can just select this property without having to do the computed property bit, but if there is something wrong with the expression you have maybe that is causing the computed property to actually get added. I wouldn't call it tooltip by the way as that seems too much like a keyword. I would call it theToolTip or something to be safe.

I have used "tooltip" alias. However when I try to read the tooltip property mapguide not find it on property collection. Can you help me? Regards, Matteo Can you parse the layer definition to get the expression and execute a query using the expression as the select statement with the addition of a feature id or key value?

In the layer definition the tooltip is an expression. I develop with MG 2.0.2 and ASP.NET Have any ideas?
