I made an application which draws a tree of organization based on values from an xml file.

The xaml file goes like this :


<XmlDataProvider x:Key="organization" Source="model.xml" />

<SolidColorBrush x:Key="ListBorder" Color="#FF7F9DB9"/>


<Style TargetType="{x:Type draw:Node}">
<Setter Property="OverridesDefaultStyle" Value="true"/>
<Setter Property="Template">

I want to be able to change the source at runtime by selecting a xml file from openfiledialog (like button click) how do i do that?

You can do this if you remember that you are referencing this as a resource, so you could do something like this:

XmlDataProvider provider = this.Resources["organization"] as XmlDataProvider;
if (provider != null)
{
  provider.Source = myXmlDataSource;
}
