如何在Form2、C#、Visual studio中从Form1更改tabcontrol的“Enable”属性

Question

Form2 formnew2 = new Form2();
formnew2.tabControl1.Enabled = true;

Answer 1

在Form1中引用Form2。在Form2中，将TabControl的Enable属性包装在公共方法中，并从Form1调用该属性

在形式1中：

...
        Form2 form2;
        public Form1()
        {
            // initialize and show form2
            this.form2 = new Form2();
            this.form2.Show();
        }
...

在形式2中：

...
        public void EnableTabControl()
        {
            this.tabControl1.Enabled = true;
        }
...

private void btnLogin_Click(object sender, EventArgs e)
{
    // verify that it was initialized
    if (form2 != null)
    {
        this.form2.EnableTabControl();
    }
}
