I have a problem stretching the content of a ListBoxItem. I use a DataTemplate with a Grid to place the content of the last column aligned at the right. But I must have something in the basic style of the controls that prevents this kind of display - the "*" ("consume all the rest of space") displays like "auto" ("take only what you really need").
Style of all ListBoxes:
<Style TargetType="{x:Type ListBox}">

</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Category should be left, Phone & Mobile should be on the right and Name & Position should fill the whole space that is left. It seems to be that there is no "whole" space within the Items although they optically fill the space of the listboxes width.
Could anyone help me? I'm getting mad about this. :-(
