C# WPF 列表框聊天
C# WPF ListBox Chat
我正在开发 C# WPF 聊天应用程序。我希望它看起来像 Skype 聊天,所以最后添加的项目触及列表框的底部。
截图:
<ListBox Name="ListBoxMain" Grid.Column="1" Grid.Row="1">
<ListBox.ItemTemplate>
<DataTemplate>
<WrapPanel>
<TextBlock Text="{Binding User}" FontWeight="Bold" />
<TextBlock Text=": " FontWeight="Bold" />
<TextBlock Text="{Binding Text}" Width="225" TextWrapping="Wrap" HorizontalAlignment="Stretch" />
</WrapPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
您需要更新 ListBox
的内部 ItemsPanelTemplate
...试试这个:
<ListBox Name="ListBoxMain" Grid.Column="1" Grid.Row="1">
<ListBox.ItemTemplate>
<DataTemplate>
<WrapPanel>
<TextBlock Text="{Binding User}" FontWeight="Bold" />
<TextBlock Text=": " FontWeight="Bold" />
<TextBlock Text="{Binding Text}" Width="225" TextWrapping="Wrap" HorizontalAlignment="Stretch" />
</WrapPanel>
</DataTemplate>
</ListBox.ItemTemplate>
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel VerticalAlignment="Bottom"/>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
</ListBox>
