designmode总是假的 [英] designmode is always false

问题描述

我有一个用户控件，我已经在源的不同部分测试了DesigMode的值，但是从来没有得到真正的值，而且总是假的。



I读到它设置为true的第一个位置是加载事件，然后我创建了以下事件但仍然是假的。



this.Load + = new System .EventHandler（this.ReportDesigner_Load）;



private void ReportDesigner_Load（Object sender，EventArgs e）

{

IsRunningByDeveloper = this.DesignMode;

}



我不知道出了什么问题，我还检查了所有的其他解决方案网站，但没有一个工作。

我也使用许可证管理器如下，但仍处于运行时模式。

I have a user control and I have tested the value of DesigMode in different parts of source, but never get the true value and is always false.

I read that the first place that it is set to true is in load event, then I created the following event but still get false.

this.Load += new System.EventHandler(this.ReportDesigner_Load);

private void ReportDesigner_Load(Object sender, EventArgs e)
{
IsRunningByDeveloper = this.DesignMode;
}

I don't know what is wrong , I have also checked other solutions in all the sites but none of them worked .
I also used license manager as below but still in runtime mode.

if (System.ComponentModel.LicenseManager.UsageMode == LicenseUsageMode.Designtime)
                IsRunningByDeveloper = true;

任何建议都将受到赞赏

Any suggestions would be appreciated
