如何在运行时动态隐藏当前表单并显示新表单 [英] How to dynamically hide current form during run time and show new form

问题描述

在下面我试图隐藏当前表单，并希望通过

Form5显示CrystalReport。它没有发生。正在发生的是两者都在展示。我可以通过Form5看到

Gridview'gvUserInfo'（我想隐藏）和CrystalReport。当然，

水晶报告是Gridview的幕后推手。如果我减去了Gridview，我可以看到Form5的结果。

我不想从我想要隐藏的当前表单中显示Gridview。





gvUserInfo.DataSource = ds11.Tables [0];

gvUserInfo.Visible = true;

this.Visible = false;

Form5 obj1 = new Form5（）;

obj1.Show（）;

In the following I am trying to hide the current form and want to show the CrystalReport through
Form5. It is not happening. What is happening is that both are showing. I could see the
Gridview 'gvUserInfo' (which I want to hide) and CrystalReport through Form5. Ofcourse the
crystal report is behind the Gridview. If I minus the Gridview, I could see the Form5 result.
I dont want the Gridview to be shown from the current form which I want to hide.


gvUserInfo.DataSource = ds11.Tables[0];
gvUserInfo.Visible = true;
this.Visible=false;
Form5 obj1 = new Form5();
obj1.Show();

推荐答案

在创建像这样的Form5对象之前，你可以很容易地使用this.Close（）或this.Hide（）方法。



this 。关（）; //处理当前的表单对象。

Form5 obj1 = new Form5（）;

obj1.Show（）;



或



this.Hide（）; //不要处理当前的表单对象。

Form5 obj1 = new Form5（）;

obj1.Show（）;

You can easily use this.Close() or this.Hide() method before creating Form5 object like this.

this.Close(); // Dispose the current form object.
Form5 obj1 = new Form5();
obj1.Show();

or

this.Hide(); // Do not dispose the current form object.
Form5 obj1 = new Form5();
obj1.Show();
