WPF備忘錄（4）打個勾畫個叉娛樂下

 <Path Grid.Column="2" Data="M43,5 L20,40 20,40 0,20 6,15 18,26 37,7 43,5 z" Fill="Green" Margin="5" Stretch="Fill" HorizontalAlignment="Right"/>

 <Path  Margin="5" Data="M50,25 L25,50 M25,25 50,50" Fill="#FFF4F4F5" Stretch="Fill" Stroke="Red" StrokeThickness="8" HorizontalAlignment="Right"/>

 

好了，看這個紅叉叉打的，下面先來一條異常：

1.在“System.Windows.Baml2006.DeferredBinaryDeserializerExtension”上提供值時引發了異常

上圖：

這個問題我糾結了半天查了好多資料而不可得，總以為是數據綁定之類的錯誤，最后才發現是一個TextBlock的背景顏色值設錯了。

血淋淋的教訓啊浪費了半天時間就因為自己的大意。遇到這種問題如果實在找不錯問題，就一個一個剔除控件，找到出問題的控件。

2.一個自定義ListView模板，看你是否用的上

<Grid>
        <ListView  Name="LV_Test" SelectionMode="Multiple" Background="{x:Null}">
            <ListView.Template>
                <ControlTemplate>
                    <Border CornerRadius="10" BorderBrush="RoyalBlue" BorderThickness="5">
                        <ScrollViewer VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Disabled" >
                            <ItemsPresenter />
                        </ScrollViewer>
                    </Border>
                </ControlTemplate>
            </ListView.Template>
            <ListView.ItemsPanel>
                <ItemsPanelTemplate>
                    <WrapPanel IsItemsHost="True"/>
                </ItemsPanelTemplate>
            </ListView.ItemsPanel>
            <ListView.ItemContainerStyle>
                <Style TargetType="{x:Type ListViewItem}">
                    <Setter Property="Template">
                        <Setter.Value>
                            <ControlTemplate TargetType="{x:Type ListViewItem}">
                                <Border Name="BD_Collector" CornerRadius="5" Background="DarkSeaGreen" Width="auto" Height="30" Margin="5">
                                    <StackPanel Orientation="Horizontal">
                                    <Label Content="{Binding XH}" VerticalContentAlignment="Center" HorizontalContentAlignment="Center" FontSize="13" />
                                        <Label Content="{Binding time}" VerticalContentAlignment="Center" HorizontalContentAlignment="Center" FontSize="13" />
                                    </StackPanel>
                                </Border>
                                <ControlTemplate.Triggers>
                                    <Trigger Property="IsMouseOver" Value="True">
                                        <Setter TargetName="BD_Collector" Property="Background" Value="YellowGreen" />
                                    </Trigger>
                                    <Trigger Property="IsSelected" Value="True">
                                        <Setter TargetName="BD_Collector" Property="Background" Value="DarkGreen" />
                                    </Trigger>
                                </ControlTemplate.Triggers>
                            </ControlTemplate>
                        </Setter.Value>
                    </Setter>
                </Style>
            </ListView.ItemContainerStyle>
            <ListView.View>
                <GridView>
                    <GridViewColumn Header="序號"   DisplayMemberBinding="{Binding XH}" Width="100"/>
                    <GridViewColumn Header="日期" DisplayMemberBinding="{Binding time}" Width="140"/>

        </ListView>
    </Grid>
