Silverlight - templated usercontrols and automatic conversion

When changing from manually defining my fields and values in xaml,

to defining a custom/templated usercontrol some of my bindings stopped working.

I created a custom control with two properties,

FeltLabel

and

FeltVerdi

FeltVerdi was defined as a textbox, and in my generic.xaml I had content bound like this:

    <Style TargetType="local:DataFelt">

        <Setter Property="Template">

            <Setter.Value>

                <ControlTemplate TargetType="local:DataFelt">

                    <Grid>

                        ….

                            <TextBox Style="{StaticResource felt}"

                                        Text="{TemplateBinding FeltVerdi />

                        ….

                    </Grid>

                </ControlTemplate>

            </Setter.Value>

        </Setter>

    </Style>

This worked ok for most of the fields I bound to the ViewModel, but for a couple of fields it seemed as if the binding wasn't working anymore.

After doublechecking my code and bindings I couldn't find anything wrong, so I started to notice that the fields that wouldn't display anymore

were fields defined as numbers in my ViewModel.

It looked like the builtin automatic converters didn't work any more.

I googled it and found a post that helped me, see below.

The solution was to change the binding like this:

        <Style TargetType="local:DataFelt">

        <Setter Property="Template">

            <Setter.Value>

                <ControlTemplate TargetType="local:DataFelt">

                    <Grid>

                        ….

                            <TextBox Style="{StaticResource felt}"

                                        DataContext="{TemplateBinding FeltVerdi}" Text="{Binding}" />

                        ….

                    </Grid>

                </ControlTemplate>

            </Setter.Value>

        </Setter>

    </Style>

This way automatic conversion stilll works, and my numbers etc is displaying nicely
