WPF Datasheet Text Ellipsis Doesn't Work

Question

I have a column with long user comments. I download it with the following code ...

<my:DataGridTextColumn Header="Message"
                       Binding="{Binding UserMessage, Mode=OneWay}" 
                       CanUserSort="True">
    <my:DataGridTextColumn.ElementStyle>
        <Style TargetType="{x:Type TextBlock}"
               BasedOn="{StaticResource {x:Type TextBlock}}">
               <Setter Property="TextWrapping"
                       Value="NoWrap" />
               <Setter Property="TextTrimming"
                       Value="CharacterEllipsis"/>                                    
               <Setter Property="ToolTip"
                       Value="{Binding Path=UserMessage, Mode=OneWay}"/>
        </Style>
    </my:DataGridTextColumn.ElementStyle>
</my:DataGridTextColumn>

But the ellipsis will not work. The column continues to display long data text. In addition, when I set the width of the text block explicitly to some value, the ellipsis works fine, but when I resize my column, it will not display more text in it.

Is there any way to do this?

Thanks Vinet Sanke.

Try setting the width of columns for which only static width is required. In this column you set the width to "*"

<my:DataGridTextColumn Header="Message"
                       Binding="{Binding UserMessage, Mode=OneWay}" 
                       CanUserSort="True"
                       Width="*">
    <my:DataGridTextColumn.ElementStyle>
        <Style TargetType="{x:Type TextBlock}"
               BasedOn="{StaticResource {x:Type TextBlock}}">
               <Setter Property="TextWrapping"
                       Value="NoWrap" />
               <Setter Property="TextTrimming"
                       Value="CharacterEllipsis"/>                                    
               <Setter Property="ToolTip"
                       Value="{Binding Path=UserMessage, Mode=OneWay}"/>
        </Style>
    </my:DataGridTextColumn.ElementStyle>
</my:DataGridTextColumn>
