推荐答案

请参阅

See TabControl.SelectedIndex at MSDN[^] All your button needs to do is read this, check it against the number of tab pages, increment if necessary, and write it back.

您可以通过使用给定的代码按需单击按钮来更改选项卡

you can change your tab by click on button as you wish by using given code

int i = 0;
        private void btnext_Click(object sender, EventArgs e)
        {
            if (i <= 3)  //using 3 A/c to your question you can change it
            {
                tabControl1.SelectedIndex = i;
                tabControl1.TabPages[i].Parent.Focus();
                i++;    // Increase counter
            }
            else
            {
             //you Message
            }
        }

您可以使用此代码

you can use this code

private void btnNext_Click(object sender, EventArgs e)
        {
            int NumIndex = tabControl1.SelectedIndex;
            if (NumIndex < tabControl1.TabPages.Count-1)
            {
                tabControl1.SelectTab(NumIndex + 1);
            }
        }
