我有一个页面上有一堆用户控件.我想能够直接在我的代码中被替换的内容中有“宏”或“占位符”.这不是很重要,但我使用Ektron作为我的CMS.
在发送到客户端之前,是否有任何页面事件可以挂接到整个呈现页面内容上的字符串替换？
UPDATE
这是我目前用来完成这个的代码：
protected override void Render(HtmlTextWriter writer)
{
string content = string.Empty;
using (var stringWriter = new StringWriter())
using (var htmlWriter = new HtmlTextWriter(stringWriter))
{
// render the current page content to our temp writer
base.Render(htmlWriter);
htmlWriter.Close();
// get the content
content = stringWriter.ToString();
}
// replace our placeholders
string newContent = content.Replace("$placeholder1$","placeholder1 data").Replace("$placeholder2$","placeholder2 data");
// write the new html to the page
writer.Write(newContent);
}
解决方法
你试过覆盖渲染方法吗？
protected override void Render(HtmlTextWriter writer)
{
StringBuilder htmlString = new StringBuilder(); // this will hold the string
StringWriter stringWriter = new StringWriter(htmlString);
HtmlTextWriter tmpWriter = new HtmlTextWriter(stringWriter);
Page.Render(tmpWriter);
writer.Flush();
writer.Write(DoReplaceLogic(htmlString.ToString()););
}
