添加资源“png”文件到按钮图像

问题描述

Private Sub MakeButton(sp As StackPanel, sStr As String)
    Dim btn As New Button()
    Dim sp1 As New StackPanel()
    Dim img As System.Drawing.Bitmap

    img = My.Resources.FldrClose

    sp1.Orientation = Orientation.Horizontal

    'Wrong
    sp1.Children.Add(New Image With {.Source = img})


    'sp1.Children.Add(New Image With {.Source = New BitmapImage(New Uri("c:\tmp\FldrOpen.png")),
    '                                 .Width = 100,
    '                                 .HorizontalAlignment = Windows.HorizontalAlignment.Left})


    sp1.Children.Add(New TextBlock With {.Text = sStr,
                                         .Width = 100,
                                         .HorizontalAlignment = Windows.HorizontalAlignment.Right})

    btn.Height = 30
    btn.Width = 200
    btn.Content = sp1

    sp.Children.Add(btn)
End Sub

在参考资料中，我有几个png文件。这个png文件我要添加到我的按钮。

In Resources I have several "png" files. This "png" files I want to add to my buttons.

推荐答案

<button>
    <grid>
        <grid.rowdefinitions>
            <rowdefinition />
            <rowdefinition />
        </grid.rowdefinitions>
        <image grid.row="1" x:name="ImagePlaceHolder" xmlns:x="#unknown" />
        <textblock grid.row="2" x:name="TextPlaceHolder" xmlns:x="#unknown" />
    </grid>
</button>

然后你可以在运行时引用这些控件。



然而，更好的解决方案是拥有两个数据类

Then you could refer to those controls at runtime.

However, a better solution would be to have two dataclasses

ButtonContentWithImage

ButtonContentWithoutImage

然后将按钮的datacontext设置为其中一个类，并在WPF窗口/控件/页面的资源中使用Datatemplates来正确显示它们。

Then set the datacontext of the button to one of those classes and use Datatemplates in the resources of the WPF window/control/page to display them properly.
