如何启用C#.net中子窗体中父窗体中的按钮

问题描述

大家好
在父窗体中，我将button属性设置为enable false，以及如何从C#.net的子窗体(Windows窗体)中启用按钮?

Hi all
In parent form I put the button property as enable false and how to enable the buttons from child form in C#.net (windows forms)?

推荐答案

private void btnShowChild_Click(object sender, EventArgs e)
{
            ChildForm ch = new ChildForm();
            ch.Owner = this;
            ch.ShowDialog();
}

2.在childForm中，获取对Parent表单的引用(先前已将其设置为childForm的所有者)，如下所示:

2. In childForm, get the reference to Parent form (which was earlier set as owner of the childForm ) as shown here

ParentForm p = (ParentForm)this.Owner;

3.一旦从子表单中引用了父表单对象实例，就可以使用以下方式获得任何控件(例如parentForm中名为"button2"的按钮)

3. Once you have the reference to parent form object instance from child form, you get any control(say a button named "button2" in parentForm) using following way

private void btnDisableParentButton_Click(object sender, EventArgs e)
{

            ParentForm p = (ParentForm)this.Owner;
            Control[] c = p.Controls.Find("button2", true);
            Button b = (Button)c[0];
            b.Enabled = false;
}

注意:我正在从子窗口中禁用父窗体中名为"button2"的按钮.

请让我知道这对您是否有用.

谢谢

NB: I am disabling a button named "button2" in Parent form from a child window.

Please let me know if that was usefull to you.

Thanks
