Hello experts,

i'm trying to bind IsReadOnly property on xamgrid to a boolean property on my datacontext(ViemModel).

and for some odd reason it wont bind.

i want to block and unblock the columns the editing dynamically

here is a snipet of my ViewModel

private

bool m_isReadOnly = true;

get { return m_isReadOnly; }

set{m_isReadOnly = value;

RaisePropertyChanged("IsReadOnly");

}

and in the xaml i do the next binding

<

ig:TextColumn HeaderText="Pressure [m]" Key="Pressure"

IsSummable="False"

IsFixable="False"

IsReadOnly="{Binding Path=IsReadOnly}">

the column can see the properties of my VM but isreadonly wont work when i change the property true/false while running.

any ideas?
