    Telerik Version = Q3 2012

    I add a FilterDescriptor to GridView like this, bat i can't activate the visual state in GridView (property = IsActive)
    FilterDescriptor filter = new FilterDescriptor();
    filter.Member = "Code";
    filter.Operator = FilterOperator.IsNotEqualTo;
    filter.Value = MyObject.Code;                              
    this.GridSource.FilterDescriptors.Add(filter);
    How can i set IsActive to True?

    Best regards

    Hello Boukerroui, 

    By design the distinct filter values cannot be checked programmatically. That is why the CheckBox with the "True" distinct value is not checked. It might be possible to create a custom filtering control that can does that, by following the Custom Filtering Control documentation article and the CustomFilterControl SDK example. However, the specific implementation of the desired logic is up to you, since it's entirely custom.

    I hope this helps.
