Dockpanel无法以继承的形式工作 [英] Dockpanel not working in inherited form

问题描述

我正在处理使用One Main Form的项目，其他表单通过DigitalRune.Windows.Docking Dock Panel从Main表单继承。现在我想通过此dockpanel转到下一个表单，该dockpanel也继承自Main Form

I m working on project in which I used One Main Form and other forms are inherited from Main form through DigitalRune.Windows.Docking Dock Panel . now I want to go to next form through this dockpanel which is also inherited from Main Form

private void btnNext_Click(object sender, EventArgs e)
        {
                if (fSecond == null)
                {
                    fSecond = new frmSecondLecture();
                    fSecond.Show(dp, DigitalRune.Windows.Docking.DockState.Document);
                }
                else
                {
                    fSecond.Activate();
                }

我在上面的代码中设置了dock panel dp的名称。现在它在下一行显示dp错误

I set name of dock panel dp in above code. Now it show me error on dp in following line

fSecond.Show(dp, DigitalRune.Windows.Docking.DockState.Document);

它告诉我dp在当前上下文中不存在。我现在该怎么办？

It show me that dp is not exist in current context. What can I do now?
