WPF - column width issue in list description table

Question

Listed below xaml using .Net3.5 -

<ListView Name="RawData" AlternationCount="2" ItemsSource="{Binding}"
          ScrollViewer.VerticalScrollBarVisibility="Visible" Grid.Row="1"
          Grid.ColumnSpan="4"
          IsSynchronizedWithCurrentItem="True"
          sorter:GridViewSort.AutoSort="True"
          sorter:GridViewSort.ShowSortGlyph="False" >
    <ListView.ItemContainerStyle>
        <Style TargetType="ListViewItem">
            <Setter Property="HorizontalContentAlignment" Value="Center" />
            <Style.Triggers>
                <Trigger Property="ItemsControl.AlternationIndex" Value="1">
                    <Setter Property="Background" Value="LightGray"></Setter>
                </Trigger>
            </Style.Triggers>
        </Style>
    </ListView.ItemContainerStyle>
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Date" DisplayMemberBinding="{Binding Path=GetDate}"
                            Width="Auto" sorter:GridViewSort.PropertyName="GetDateTime"/>
            <GridViewColumn Header="Time" DisplayMemberBinding="{Binding Path=GetTime}"
                            Width="Auto" sorter:GridViewSort.PropertyName="GetDateTime"/>
            <GridViewColumn Header="Scan Time" DisplayMemberBinding="{Binding Path=ScanTimeSec}"
                            sorter:GridViewSort.PropertyName="ScanTimeSecond"  Width="Auto"/>
            <GridViewColumn Header="Ping Time" DisplayMemberBinding="{Binding Path=PingTimeSec}"
                            sorter:GridViewSort.PropertyName="PingTimeSec"  Width="Auto" />
            <GridViewColumn Header="Fault Messages"
                            DisplayMemberBinding="{Binding Path=ErrorMessages}"
                            sorter:GridViewSort.PropertyName="ErrorMessages" Width="Auto"/>
        </GridView>
    </ListView.View>
</ListView>

My problem is with the first and last columns. They do not change automatically to fit the contents of the data. I could use a fixed width, but this will cause problems later in the project when I allow users to change the font size.

Each solution I found is like setting width = "auto", and WPF will do it for you. However, he does not. Since I'm a little new to WPF, I'm not sure what to do.

Answer 1

auto Width.You width.Like Width = "100". .
