    Hello,
    I have simple MVVM scenario with RadExpander.

    <telerik:RadExpander  IsExpanded="{Binding IsActive, Mode=OneWay}" ...

    RadExpander do not reflect changes on IsActive property.


    I try to check if it not my mistake. I change to "IsEnabled".

    <telerik:RadExpander  IsEnabled="{Binding IsActive, Mode=OneWay}" ...

    With "IsEnabled" all working fine.

    So I think IsExpanded is broken on your side.

    Version 2011.1.223.1040

    Hello Jaroslav Půbal,

    This is a known issue in this version of RadExpander. The good news is that this is fixed in the official Q1 2011 SP1 (0419) version of RadControls.

    Hi Saravanan,

    I tested this issue with our official 2011 Q2 release and I confirm that it is fixed there.
    Can you please try it and let us know if you still experience any problems?

    All the best,

    Hi,

    I have the same problem, I can´t bind IsExpanded...

    I have this property:

    private bool _expande;
           public bool Expande
           {
               get { return _expande; }
               set { _expande = value; OnPropertyChanged("Expande"); }
           }

    If I did in my constructor of ViewModel Expande = true, this works good, and the expander shows expanded, but if I try do Expande = false in other part of my viewModel doesn´t work.

    Any idea why?

    Thanks in advance.
