从控件的调用方法未完全运行. [英] Calling Method from Control not Fully Running.

问题描述

(使用Teleriks''RadPageView)

我在用户控件中有一个创建并填充"RadPageView"的方法.

(Using Teleriks'' RadPageView)

I have a Method inside a usercontrol which creates and populates a "RadPageView".

public void CreateDemoMap()
{
    RadPageViewPage pTest = new RadPageViewPage();
    pTest.Text = "Live Map (Demo)";
    radPageViewX.Pages.Add(pTest);
    WebMap wMap = new WebMap();
    pTest.Controls.Add(wMap);
    MessageBox.Show("TEST");
}

通过相同的形式，但在用户控件之外，我有一个调用Method的按钮.

From the same form but outside of the user control I have a button calling on the Method.

private void radButtonElement4_Click_1(object sender, EventArgs e)
{
    ProjectDashControl PDC = new ProjectDashControl();
    PDC.CreateDemoMap();
}

该方法可以运行(文本框显示"Test")，但是不会生成RadPageView.
运行本地化方法-我得到了预期的结果，并且工作正常.

The method does run (Textbox Shows "Test") But the RadPageView does not generate.
Running the method localy - I get the intended results and it works fine.

public ProjectDashControl()
{
    InitializeComponent();
    CreateDemoMap();
}

所以我不确定如何解决这个问题.或与此相关的问题是什么；我正在创建的实例优先于后者吗?不在表单中运行?赞赏或建议-提前致谢.

So I''m not sure how to fix this; or for that matter what the issue is; Is the instance i''m creating taking presedence over the latter? Not running with-in the form? Suggestions or Answers Appreciated - Thanks in Advance.

推荐答案

您必须将变量ProjectDashControl PDC移到类的全局范围内，否则当方法radButtonElement4_Click_1结束.

You have to move variable ProjectDashControl PDC to global scope of your class or else GC will collect PDC when the method radButtonElement4_Click_1 ends.

将变量ProjectDashControl PDC移动到全局范围并更改为实例.

Moved Variable ProjectDashControl PDC to Global Scope and Changed to Instance.

ProjectDashControl PDC = ProjectDashControl.Instance();
