wpf grid as itemspaneltemplate给出了不一致的高度

标签: wpf listbox grid height row

我试图制作一个星期调度程序

所以每天我都有一个列表框,其中有一个网格作为其itemspaneltemplate,每个单独的会话从数据库中获取其行和行数并且它的工作非常好

问题是当我有一个简短的约会,所以rowspan只有2或3而内容更长,在这种情况下,包含约会的行增长以容纳更大的内容

我不想那样,即使我没有看到所有数据,也就是约会反映他们的时间跨度

我尝试了很多我在网上找到的答案组合

继承整个标记

<ListBox Name="lsbTasks" Loaded="lsbTasks_Loaded_1" HorizontalContentAlignment="Stretch" ScrollViewer.HorizontalScrollBarVisibility="Disabled" VerticalContentAlignment="Stretch" >
                            <ListBox.ItemsPanel>
                                <ItemsPanelTemplate>
                                    <Grid Initialized="Grid_Initialized_1" Background="Thistle"  IsSharedSizeScope="True"/>
                                </ItemsPanelTemplate>
                            </ListBox.ItemsPanel>
                            <ItemsControl.ItemContainerStyle>
                                <Style>
                                    <Setter Property="Grid.Row" Value="{Binding BusyFrom,Converter={StaticResource BusyFromConverter}}" />
                                    <Setter Property="Grid.RowSpan" Value="{Binding BusyMinutes,Converter={StaticResource BusyMinutesConverter}}" />
                                    <Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Auto" />
                                </Style>
                            </ItemsControl.ItemContainerStyle>
                            <ListBox.ItemTemplate>
                                <DataTemplate>
                                    <ScrollViewer ScrollViewer.CanContentScroll="True" ScrollViewer.VerticalScrollBarVisibility="Auto" ScrollViewer.IsDeferredScrollingEnabled="True">
                                        <StackPanel Background="Purple" PreviewMouseDown="DockPanel_PreviewMouseDown_1">

                                            <TextBlock TextAlignment="Center" TextWrapping="Wrap" Text="{Binding SessionPlace}" Foreground="Thistle" DockPanel.Dock="Bottom" />
                                            <TextBlock  TextAlignment="Center" TextWrapping="Wrap" Text="{Binding ClientName}" Foreground="White" FontWeight="Bold" DockPanel.Dock="Top" />
                                            <TextBlock  TextAlignment="Center" TextWrapping="Wrap" Text="{Binding OppositionName}" Foreground="White" DockPanel.Dock="Top" />
                                            <TextBlock  TextAlignment="Center" TextWrapping="Wrap" Text="{Binding SubjectName}" Foreground="Thistle" />
                                        </StackPanel>
                                    </ScrollViewer>
                                </DataTemplate>
                            </ListBox.ItemTemplate>
                        </ListBox>

并且继承了初始化代码

Private Sub Grid_Initialized_1(sender As Grid, e As EventArgs)
    Dim mnts = MyWorkDaySpan.TotalMinutes
    For i = 1 To mnts / 10
        Dim rd = New RowDefinition With {.Height = New GridLength(1, GridUnitType.Star)}
        'rd.SharedSizeGroup = "RowGroup"
        sender.RowDefinitions.Add(rd)
    Next
End Sub

但是行仍然是不均匀的,正如网格线所证明的那样

id感谢任何帮助或指导

您应该使用不同的Panel,也许是Canvas,并以ListBoxItem样式绑定Canvas.TopHeight属性。

另一种选择是编写一个custom Panel类(“CalendarPanel”),它定义了两个附加属性BusyFromBusyMinutes,并根据这些属性的值排列其子元素
