Change cell value conditionally.
posted

I have the following scenario:

I am trying to change the value of a cell by using a custom presenter (see below for the XAML). My custom presenter is being hit but the grid is not showing the new value returned by the cusom converter. Can someone point out what i am doing wrong? 

<Style x:Key="cvpValueChange" TargetType="{x:Type igDP:CellValuePresenter}">

<Setter Property="Value" Value="{Binding RelativeSource={RelativeSource Self}, Path=Value, Converter={StaticResource cvpValueConverter}}"/>

</Style>

    Hi Martin -
     
    You are trying to bind the CellValuePresenter's Value property to itself - this will not work. 
     
    The way to do this is to add a Setter for the Template property to the CellValuePresenter style, which sets the proeprty to a Template containing an element (e.g., a ContentControl) that binds to the Value property using the converter.  I have attached a simple project that demonstrates this.
