如何访问打开表单的按钮？ [英] How to access button of opened form?

问题描述

private void rbnbtnPageSetup_Click(object sender, EventArgs e)
    {
        if (IsFormOpen(typeof(GUI.Printing)))
        {

        }
        else
        {
            MessageBox.Show("Please Open Printing Form");
        }
    }

IsFormOpen（typeof（GUI。Printing））是打印表单打开时返回true的方法。



我想在打印表单中打开打印预览按钮。确保我不想打开新的打印表格。我的要求是如果打印表格打开然后按下该表格的打印prieview按钮。



请帮助我。谢谢。

推荐答案

尝试 btnPreivew_Click（null，null）; 其中 btnPreivew 是按钮的名称。

Try btnPreivew_Click(null,null); where btnPreivew is the name of your button.
