WPF: Scale Grid without scaling content - wpf

Question

Is it possible to apply a scale transform a Grid's columns and rows without scaling the content?
I would like the content of each cell to simply resize to fit the cell without being scaled (e.g. font size of text remains the same).
For example, in the following piece of XAML I would like the buttons to resize rather than scale:
<Grid Name="grid1" RenderTransformOrigin="0.5, 0.5">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="300" />
<ColumnDefinition Width="300" />
<ColumnDefinition Width="300" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="80"/>
<RowDefinition Height="80"/>
</Grid.RowDefinitions>
<Grid.RenderTransform>
<ScaleTransform ScaleX="{Binding Value, ElementName=slider1 }" ScaleY="{Binding Value, ElementName=slider1 }"
/>
</Grid.RenderTransform>
<Button Content="Button3" Margin="6" Name="button3" />
<Button Content="Button4" Grid.Column="1" Margin="6" Name="button4" />
<Button Content="Button5" Grid.Column="2" Margin="6" Name="button5" />
<Button Content="Button6" Grid.Column="0" Grid.Row="1" Margin="6" Name="button6" />
</Grid>

With the method you're applying, this isn't possible because the transform will apply to the rendering of all child controls, too.
However, by the look of your code, you want to resize your grid's columns based on the position of a slider. An easier way would be to set all the columns to Width="*" (which will have the effect of each column having equal width), remove your transform, and bind the width of the grid as a whole to the slider instead (you may need to adjust the range of your slider to suit!).
This will have different effect to a RenderTransform, though, because a RenderTransform won't affect any of the surrounding layout, and changing the Width will. Post a comment if that will be a problem and maybe there's another solution...
