<Grid RenderTransformOrigin="0.5,0.5">
        <Grid Margin="0,0,0.286,0.429" Name="LogGrid">
            <PasswordBox x:Name="Password" HorizontalAlignment="Left" Margin="130,130,0,0" VerticalAlignment="Top" Width="140"/>
            <TextBox x:Name="Login" HorizontalAlignment="Left" Height="20" Margin="140,90,0,0" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width="120"/>

            <Button x:Name="btnSignUp" Content="Sign Up" HorizontalAlignment="Left" Margin="205,170,0,0" VerticalAlignment="Top" Width="65"/>
        </Grid>
        <Grid Name="MainPart" Width="800" Height="600" Visibility="Hidden" HorizontalAlignment="Right">
            <TextBox x:Name="Chat" HorizontalAlignment="Left" Height="540" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width="800" AcceptsReturn="True" IsReadOnly="True"/>
            <TextBox Name="SendString" Width="740" Height="60" Margin="0, 540, 0, 0" HorizontalAlignment="Left"/>
            <Button x:Name="SendMsg" Margin="740, 540, 0, 0" Width="60" Height="60" HorizontalAlignment="Right" Content="Send" />  <-!!!!!!!!!!!!!!
        </Grid>

问题是:第二个网格中名为“SendMsg”的按钮不显示“内容”

Answer 1

我刚刚遇到这个问题是因为我将 Height 属性设置为 30，并将 Padding 属性设置为 15，所以我的 Content 已被填充到可见空间之外。 :)
