Question

I ve watched a few tutorials online on how to change tabs using buttons but for some reason all the code I ve tried doesn t work. I am currently running Microsoft Visual Studio 2017 and am trying to write some code for a button to change tabs. I couldn t find any differences between my code and code shown in tutorials, so it may just be a Visual Studio setting that I haven t set up correctly to allow the button correctly, but I couldn t figure out if or where it may be.

Here s my current code:

//Element event handlers
public Form1()
{
  InitializeComponent();
}

private void buttonStart_Click(object sender, EventArgs e)
{
  tabControl.SelectedTab = DestSelect;
}

private void buttonGotoIntro_Click(object sender, EventArgs e)
{
  tabControl.SelectedTab = Intro;
}

//An old computer-generated segment code for the previous button.
//When I try to remove it the computer gets mad at me.
private void GotoIntro_Click(object sender, EventArgs e)
{

}

请确认以下网站:,在上标/。

public Form1()
{
    InitializeComponent();
    buttonStart.Click += buttonStart_Click;
    buttonGotoIntro.Click += buttonGotoIntro_Click;
}

相反,它不是禁忌。 SelectedTab = DestSelect;”取而代之的是表格Control。选择Tab(当选);

I read through this article to find your (hopefully) answer: https://social.msdn.microsoft.com/Forums/vstudio/en-US/2cf22896-c5bd-4a9b-ab61-34404b55ef01/how-to-jump-to-a-specific-tab-in-the-tabcontrol?forum=vbgeneral

I assume u want to select a tab when a different Button is clicked. tabControl.SelectedIndex = [Index of tab to switch to];

Code should look like; tabControl.SelectedIndex = feeTabIndex;

如果这还不够清楚,我就确切地告诉我你想要做什么。

    private void btnPage1_Click(object sender, EventArgs e)
    {
        Button button = sender as Button ;

        // method 1
        if(button==button1)
            tabControl1.SelectedIndex = 0;
        else if(button==button2)
            tabControl1.SelectedIndex = 1;
        else // if(button==button3)
            tabControl1.SelectedIndex = 2;

        // method 2
        if(button==button1)
            tabControl1.SelectedTab = tabControl1.TabPages["tabPage1"];
        else if(button==button2)
            tabControl1.SelectedTab = tabControl1.TabPages["tabPage2"];
        else // if(button==button3)
            tabControl1.SelectedTab = tabControl1.TabPages["tabPage3"];

        // method 3
        // button Name : btnPage1, btnPage2, btnPage3
        // tabPage Name : tabPage1, tabPage2, tabPage3
        string tabName = button.Name.Replace("btn", "tab") ;
        tabControl1.SelectedTab = tabControl1.TabPages[tabName] ;
    }
