添加资源“png”文件到按钮图像 [英] Add Resource "png" file to button image

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

我建​​议阅读有关datatemplates的内容。我还没有找到一种简单的方法来动态地将图像和文本放在WPF中的按钮上，通常这样做的方法是在XAML中创建占位符。

所以你的按钮会被描述为类似这个：

I would advise reading about datatemplates. I have not found an easy way to dynamically put an image and text on a button in WPF, generally the way to do it is to create the placeholders in XAML.
So your button would be described something like this:

<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.
