WPF System.Windows.Controls.WebBrowser不呈现链接按钮 [英] WPF System.Windows.Controls.WebBrowser not rendering link buttons
问题描述
我有一个网页，我在桌面应用程序中的WPF WebBrowser控件中显示。我刚刚更新网页使用样式按钮而不是默认的灰色按钮，从asp.net按钮类型更改为asp.net LinkButton并应用CSS样式：
I have a web page that I display in a WPF WebBrowser control within a desktop application. I just updated the webpage to use styled buttons instead of the default gray buttons by changing from an asp.net Button type to an asp.net LinkButton and applying a CSS style to it:
a.btnSave
{
background: url(Resources/Images/btnSave.png) no-repeat 0 0;
display:inline-block;
width: 75px;
height: 23px;
text-indent: -9999px;
}
a.btnSave:hover {background-position: 0 -23px;}
a.btnCancel
{
background: url(Resources/Images/btnCancel.png) no-repeat 0 0;
display:inline-block;
width: 75px;
height: 23px;
text-indent: -9999px;
}
a.btnCancel:hover {background-position: 0 -23px;}
a.btnReset
{
background: url(Resources/Images/btnReset.png) no-repeat 0 0;
display:inline-block;
width: 75px;
height: 23px;
text-indent: -9999px;
}
a.btnReset:hover {background-position: 0 -23px;}
...
<asp:LinkButton ID="btnSave" runat="server" CssClass="btnSave" OnClick="btnSave_Click" OnClientClick="OnSubmit()" UseSubmitBehavior="False" Text=" " />
<asp:LinkButton ID="btnCancel" runat="server" CssClass="btnCancel" OnClick="btnCancel_Click" OnClientClick="OnSubmit()" CausesValidation="False" Text=" " />
<asp:LinkButton ID="btnReset" runat="server" CssClass="btnReset" OnClick="btnReset_Click" OnClientClick="OnSubmit()" CausesValidation="False" Text=" " />
当我在IE 8（或firefox）中查看页面时，按钮显示正确。但是当我在应用程序中的WebBrowser控件中加载页面时，缺少按钮。如果我将鼠标悬停在他们应该在哪里，我不会收到手形图标，所以不只是图像没有加载。当我查看源代码，锚标记在那里，如果我复制源并将其保存到HTML文件，并在浏览器窗口中打开它们，它们确实显示正确。在过去，我遇到了WebBrowser的麻烦，不会像浏览器一样显示浮动div，并且不得不切换到表布局。它不支持内联块显示类型还是什么？
When I view the page in IE 8 (or firefox), the buttons appear correctly. But when I load the page in the WebBrowser control within the app, the buttons are missing. If I hover over where they should be I do not receive the Hand icon so it's not just that the images are not being loaded. When I view the source, the anchor tags are there and if I copy the source and save it to an HTML file and open that in a browser window, they do appear correctly. In the past, I've had trouble with the WebBrowser not dispalying floating divs the same way a browser does and had to switch to a table layout. Does it not support the inline-block display type or something?
如果重要的话，这是为页面声明的doctype：
If it matters, this is the doctype declared for the page:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
推荐答案
默认情况下使用兼容模式，风格。将其更改为
It was using compatability mode by default which was not honoring the styles. Changing it to
<meta http-equiv="X-UA-Compatible" content="IE=9" />
或
<meta http-equiv="X-UA-Compatible" content="IE=Edge" />
修复了它。
