Question number 2)
When i put the code inside a function the key word "Page" turns from blue to black why is that?

推荐答案

您可能正在尝试访问non-static财产.但是顺便说一句，我的代码运行良好.您在VewComplaint.aspx.cs中的哪个位置编写了此代码，并确保您在同一行中遇到异常，那么我们可以为您提供更好的服务.

您是否写过这样的内容:

You may be trying to access the non-static property. But BTW your code is running good at my end. Where do you have written this code in your VewComplaint.aspx.cs and make sure you are getting the exception in the same line, then we can serve you better.

Have you written something like this:

namespace WebApplication1
{
    public partial class ViewComplaint : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

            Button b = (Button)((ViewComplaint)Page).FindControl("transitionStageBtnm");
        }

    }
}

上面的代码在我的末端运行良好.确保您不要写下了这样的内容:

the above code is running fine at my end. Make sure you don''t have written something like this:

namespace WebApplication1
{
    public partial class ViewComplaint : System.Web.UI.Page
    {
        Button b = (Button)((ViewComplaint)Page).FindControl("transitionStageBtnm");
        protected void Page_Load(object sender, EventArgs e)
        {


        }

    }
}

这将给出错误:Error 1 An object reference is required for the non-static field, method, or property ''System.Web.UI.Control.Page.get''
希望对您有所帮助:)
