'Auto' value in binding property 'width'

Must attach to the property Width, what I'm doing this:

     <ColumnDefinition Width="{Binding Path=TabPanelWidth, RelativeSource={RelativeSource TemplatedParent}}" />

-

     public float TabPanelWidth
     {
         get {return (float) GetValue (TabPanelWidthProperty);}
         set {SetValue (TabPanelWidthProperty, value);}
     }
     public static readonly DependencyProperty TabPanelWidthProperty = DependencyProperty.Register ("TabPanelWidth", typeof (float), typeof (BivTabControl), new UIPropertyMetadata (null));

But I need a possibility to set not only fixed values, but the values which are expressed in XAML as Auto, 0.5*, and the like.

Any ideas?

Your TabPanelWidth property must be of type GridLength. With GridLength you can set auto/star size using GridUnitType.

In fact, I wonder why binding to a float works at all.

Use the same datatype instead of a float, it's called GridLength.
