tabpage فعال

[wolf_majid]

هر کاری کردم با switch بنویسم نشد
از این کد استفاده کن

  private void tabControl1_Selected(object sender, TabControlEventArgs e)

        {

            if (e.TabPage == tabPage1)

            {

                this.Text  = ":D";

                MessageBox.Show("Selected Tab Is " + tabPage1.Name);

            }

            else if (e.TabPage == tabPage2)

            {

                MessageBox.Show("Selected Tab Is " + tabPage2.Name);

            }

            else

            {

                MessageBox.Show("Selected Tab Is " + "I Dont Know ...! :D");

            }

            

        }

و

 private void Form1_Shown(object sender, EventArgs e)

        {

            tabControl1_Selected(this, new TabControlEventArgs(tabPage1, 0, TabControlAction.Selected));

        }
