C# 更改Repeater Itemcommand事件中LinkButton的CSS类

我想更改位于repeater控件内的linkbutton的CSS类，在repeater itemcommand事件中，我正在使用此代码

 if (e.CommandName == "read")
                {
                    LinkButton btnread = (LinkButton)e.Item.FindControl("cmdread");             
                     bool isread = true;
                    if (btnread.CssClass == "red-read")
                    {
                        isread = false;
                    }

                    if (isread)
                    {
                        btnread.CssClass = "";
                        btnread.CssClass = "red-read";

                    }
                    else
                    {
                        btnread.CssClass = "";
                        btnread.CssClass = "grey-read";
                    }

                    }

if (isread )
                    {
                        btnread.CssClass = btnread.CssClass.Replace("grey-read","red-read");


                    }
                    else
                    {
                    btnread.CssClass = btnread.CssClass.Replace("read-read","grey-read");

                    }

但它不起作用，我也试过这个代码

 if (e.CommandName == "read")
                {
                    LinkButton btnread = (LinkButton)e.Item.FindControl("cmdread");             
                     bool isread = true;
                    if (btnread.CssClass == "red-read")
                    {
                        isread = false;
                    }

                    if (isread)
                    {
                        btnread.CssClass = "";
                        btnread.CssClass = "red-read";

                    }
                    else
                    {
                        btnread.CssClass = "";
                        btnread.CssClass = "grey-read";
                    }

                    }

if (isread )
                    {
                        btnread.CssClass = btnread.CssClass.Replace("grey-read","red-read");


                    }
                    else
                    {
                    btnread.CssClass = btnread.CssClass.Replace("read-read","grey-read");

                    }

你能试试这个代码吗。如果条件设置为

isread=false

，则替换为以下代码

if (btnread.CssClass.Equals("red-read",StringComparison.InvariantCultureIgnoreCase))
{
      isread = false;
}

还可以使用以下命令名条件

if (e.CommandName.Equals("read",StringComparison.InvariantCultureIgnoreCase))

让我们知道错误是否仍然存在？

值IsFlag，它在哪里设置？亲爱的@syed为什么不使用jquery，因为它可以让您更轻松地使用jqueryyou@unseendreamzzz你能给我一些使用jquery和repeater的示例代码/教程吗？@HassanMokdad查看我的更新问题]你能提供你的HTML代码吗？如果（btnread.CssClass==“红色读取”）此代码工作正常，我必须根据isread值更改上的CSS类，该值符合预期。我认为代码工作正常。但问题在于CSS。可能是浏览器上没有CSS类或CSS样式。检查CSS是否已注册？尝试检查页面源代码或firebug（在firefox中）或开发工具（在IE中）。在第二个代码块中，“red read”的拼写是“read read”
