Hello everybody,

I have the feeling that this is a very basic and stupid question, but I am having hard time anyway... so

I have a window hosting a XamGrid. I am setting the columns. This is the very simple declaration

<ig:XamGrid x:Name="dataGrid" AutoGenerateColumns="False" ItemsSource="{Binding Path=Properties_w}" ColumnWidth="Auto">
<ig:XamGrid.ColumnResizingSettings>
<ig:ColumnResizingSettings AllowCellAreaResizing="True" AllowColumnResizing="Disabled"/>
</ig:XamGrid.ColumnResizingSettings>
<ig:XamGrid.Columns>
<ig:TextColumn Key="PropertyName" HeaderText="{locExt:Localizer prop}"/>
<ig:TextColumn Key="Category" HeaderText="{locExt:Localizer category}"/>
<ig:TextColumn Key="SubscribedTo" />
<ig:TextColumn Key="DataType" />
<ig:TextColumn Key="Units" />
<ig:TextColumn Key="UserAccess" />
<ig:TextColumn Key="ConstraintStatus" Width="*"/>
</ig:XamGrid.Columns>
</ig:XamGrid>

As you can see, I set Auto for every column's width, except for the last one (*) which will take all available space.

I simply want my window to adapt to the width of the grid.

How can i do that?
 If I set Width="Auto" the window will (don't know why) grow more than necessary. If I set a constant number (e.g. Width="500")  the window won;t resize (scrollbars will appear). If I set SizeToContent="Width" the window will grow, grow grow...

Why is that so hard:? What am I missing?

The window will simply host this grid and I want it to have the proper size

PS: I am using XamGrid, but if you have a suggestion for XamDataGrid I can use it, no problem

Thanks in advance!
