 Hello Friends 

I want to get sill height parameter when i run the code i get this

How can i get sill height value

Thanks in advance...

To get the value stored in the parameter, use one of these methods:

• AsDouble
• AsString
• AsElementId
• AsInteger

You can check how the data is stored with the Parameter.StorageType property

Once you get the value (in your case with AsDouble) you can then convert it to a string with ToString to show it in the TaskDialog

Thank you for your quick reply
param.AsValueString() solve the problem
