With xaml
<Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="321*" />
            <ColumnDefinition Width="335*" />
        </Grid.ColumnDefinitions>
        <StackPanel>
            <Button Margin="5" GotFocus="GotFocus">Test</Button>
            <TextBox Margin="5" GotFocus="GotFocus">text</TextBox>
        </StackPanel>
        <telerik:RadPropertyGrid x:Name="pg" Grid.Column="1"
                                 LabelColumnWidth="100" IsGrouped="True" AutoGeneratePropertyDefinitions="True"
                                 telerik:StyleManager.Theme="Vista"/>
    </Grid>
and code

        private void GotFocus(object sender, RoutedEventArgs e)
        {
            pg.Item = sender;
        }
if you switch between controls than you see errors like this
System.Windows.Data Error: 40 : BindingExpression path error: 'ClickMode' property not found on 'object' ''TextBox' (Name='')'. BindingExpression:Path=ClickMode; DataItem='TextBox' (Name=''); target element is 'RadComboBox' (Name=''); target property is 'SelectedValue' (type 'Object')
System.Windows.Data Error: 40 : BindingExpression path error: 'Command' property not found on 'object' ''TextBox' (Name='')'. BindingExpression:Path=Command; DataItem='TextBox' (Name=''); target element is 'TextBox' (Name=''); target property is 'Text' (type 'String')
System.Windows.Data Error: 40 : BindingExpression path error: 'CommandParameter' property not found on 'object' ''TextBox' (Name='')'. BindingExpression:Path=CommandParameter; DataItem='TextBox' (Name=''); target element is 'TextBox' (Name=''); target property is 'Text' (type 'String')
System.Windows.Data Error: 40 : BindingExpression path error: 'CommandTarget' property not found on 'object' ''TextBox' (Name='')'. BindingExpression:Path=CommandTarget; DataItem='TextBox' (Name=''); target element is 'TextBox' (Name=''); target property is 'Text' (type 'String')
Because the propertygrid do not clear bindings after change selected item.
The version is 2011.3.1330.40 Dev
