I just migrated to a new PC with windows 8.1 pro. I installed visual studio community edition update 4 and crystal reports for visual studio version 13.0.13.1597. All installed with no problems. I have a vb .net project using the crystal report WPF viewer control.
All reports display correctly but I am getting binding errors in the visual studio IDE.
The errors are:
System.Windows.Data.Error: 5 : Value produced by BindingExpression is not valid for target property.; Value='<null>' BindingExpression:Path=TooTip: DataItem='Button' (Name='btnOpen'); target element is 'Button' (Name=btnOpen'); target property is 'Name' (type 'String')
There are 14 of theses errors for different buttons.
I have seen the problem mentioned throughout the crystal reports forums but have not found an answer to eliminate the binding errors.The errors occur as soon as the control is initialized.
