WPF-GridView设置列宽按比例分配

1. 将ListView包裹在一个父Grid中
2. 写一个与ListView平行的Grid，设置该Grid的列数与ListView中GridView的列数相同，将该Grid各列设置列宽按比例分配
3. 将ListView中GridView的各列的Width绑定上述Grid的ActualWidth
4. 这样，通过设置上述Grid各列的比例，就对应设置了ListView中GridView的各列的比例

 1 <Grid Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="3">
 2     <Grid>
 3         <Grid.ColumnDefinitions>
 4             <ColumnDefinition Width="3*" />
 5             <ColumnDefinition Width="2*" />
 6             <ColumnDefinition Width="8*"/>
 7             <ColumnDefinition Width="5*"/>
 8             <ColumnDefinition Width="5*"/>
 9         </Grid.ColumnDefinitions>
10         <Grid Grid.Column="0" x:Name="HumidifyEventLogCol0"/>
11         <Grid Grid.Column="1" x:Name="HumidifyEventLogCol1"/>
12         <Grid Grid.Column="2" x:Name="HumidifyEventLogCol2"/>
13         <Grid Grid.Column="3" x:Name="HumidifyEventLogCol3"/>
14         <Grid Grid.Column="3" x:Name="HumidifyEventLogCol4"/>
15     </Grid>
16
17     <ListView Name="HumidifyEventLog" Style="{StaticResource ListViewStyle}" ItemContainerStyle="{StaticResource ResourceKey=ListViewItemStyle}">
18         <ListView.View>
19             <GridView ColumnHeaderContainerStyle="{StaticResource GridViewColumnHeaderStyle}">
20                 <GridViewColumn Header="设备" Width="{Binding ElementName=HumidifyEventLogCol0,Path=ActualWidth}" DisplayMemberBinding="{Binding Path=Source, Converter={StaticResource ChamberNameEnToCn}}"/>
21                 <GridViewColumn Header="故障ID" Width="{Binding ElementName=HumidifyEventLogCol1,Path=ActualWidth}" DisplayMemberBinding="{Binding Path=Code}"/>
22                 <GridViewColumn Header="故障描述" Width="{Binding ElementName=HumidifyEventLogCol2,Path=ActualWidth}" DisplayMemberBinding="{Binding Path=Remark}"/>
23                 <GridViewColumn Header="故障开始时间" Width="{Binding ElementName=HumidifyEventLogCol3,Path=ActualWidth}" DisplayMemberBinding="{Binding Path=StartTime}"/>
24                 <GridViewColumn Header="故障结束时间" Width="{Binding ElementName=HumidifyEventLogCol4,Path=ActualWidth}" DisplayMemberBinding="{Binding Path=EndTime}"/>
25             </GridView>
26         </ListView.View>
27     </ListView>
28 </Grid>
