我正在使用WPF创建一个应用程序,我有一个带有Awesomium WebControl的UserControl。
当我将这个UserControl的副本添加到我的主窗口时,我从WindowsBase.dll获得一个ArgumentException,说“宽度和高度必须为正”。
这是UserControl:
<UserControl x:Class="ForumPost.ForumPost"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
mc:Ignorable="d" MinWidth="505" MinHeight="250" xmlns:my="http://schemas.awesomium.com/winfx">
<Grid Name="postGrid" Margin="5">
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Grid Background="#3166A1">
<Grid.RowDefinitions>
<RowDefinition MinHeight="150" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition MinWidth="150" />
<ColumnDefinition MinWidth="100" />
<ColumnDefinition MinWidth="125" />
<ColumnDefinition MinWidth="125" />
</Grid.ColumnDefinitions>
<Grid Height="150">
<Grid.RowDefinitions>
<RowDefinition Height="25" />
<RowDefinition Height="125" />
</Grid.RowDefinitions>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition MinWidth="20"/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Image Margin="0 0 5 0" Name="specialUserFlag"/>
<TextBlock TextAlignment="Center" FontWeight="Bold" FontSize="16" Foreground="White" Name="postUsername" Grid.Column="1"/>
</Grid>
<Image Grid.Row="1" MaxWidth="125" MaxHeight="125" Name="postAvatar" />
</Grid>
<TextBlock Grid.Column="2" TextAlignment="Center" FontWeight="Bold" FontSize="16" Foreground="White" VerticalAlignment="Center" Name="postTimestamp" TextWrapping="Wrap" />
</Grid>
<my:WebControl Grid.Row="1" Name="webBrowser"/>
</Grid>
这是我的主窗口,正如@LukeWoodward所要求的那样:
<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:Microsoft_Windows_Themes="clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Aero" x:Class="Saxaphone.MainWindow"
Title="MainWindow" Height="850" Width="1600"
Icon="main.ico">
<Grid x:Name="MainGrid">
<Grid.RowDefinitions>
<RowDefinition />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="305" />
<ColumnDefinition MinWidth="1017" />
</Grid.ColumnDefinitions>
<TreeView x:Name="ForumView" ScrollViewer.HorizontalScrollBarVisibility="Diforumbled" Style="{DynamicResource ForumViewStyle}" SelectedItemChanged="ForumView_SelectedItemChanged" />
<Grid x:Name="forumGrid" Grid.Column="1">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="512" />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<ScrollViewer VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Hidden" Grid.Column="0" Height="{Binding ActualHeight, ElementName=forumGrid}">
<StackPanel x:Name="forumThreads"></StackPanel>
</ScrollViewer>
<ScrollViewer VerticalScrollBarVisibility="Visible" HorizontalScrollBarVisibility="Auto" Grid.Column="1" Height="{Binding ActualHeight, ElementName=forumGrid}">
<StackPanel x:Name="forumPosts"/>
</ScrollViewer>
</Grid>
</Grid>

我现在能够重现你正在获得的ArgumentException。我怀疑这是Awesomium中的一个错误。我建议您通过http://support.awesomium.com/联系Awesomium支持。
我发现以下XAML足以重现ArgumentException。在运行时不需要任何用户控件或添加控件:
<StackPanel>
<as:WebControl xmlns:as="http://schemas.awesomium.com/winfx" />
</StackPanel>
我发现可以通过在Width
上设置明确的Height
和WebControl
来解决此问题。似乎WebControl
不喜欢进入StackPanel
,除非它(WebControl
) {em} Width
和{{1} } set。
