        </Grid.RowDefinitions>        <ProgressBar Height="20" Width="200" Margin="0,4,0,0" Name="ProgressBar1" HorizontalAlignment="Center" VerticalAlignment="top" />    </Grid>在“System.Windows.Markup.StaticResourceHolder”上提供值时引发了异常。

Answer 1

您能贴一下全部代码么？应该是其他地方的错误，不是ProgressBar本身的问题。

Answer 2

类代码如下：
<Window x:Class="TestPresentor.TestSplash"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="TestSplash" Height="300" Width="300">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition />
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition/>
        </Grid.ColumnDefinitions>
        <ProgressBar Grid.Row="0" Grid.Column="0" Height="20" Width="200" Margin="0,4,0,0"   Name="ProgressBar1" HorizontalAlignment="Center"  VerticalAlignment="Center" />    </Grid>
</Window>

Answer 3

跟项目应用的模板起冲突，定义一个Style进行应用即可。
