禁用標籤頁，當按鈕被點擊在C＃

Question

使我有這個代碼，以禁用標籤頁：

private void tabControl_Selecting(object sender, TabControlCancelEventArgs e) 
    { 
     if (e.TabPage == tabPage) 
     { 
      e.Cancel = true; 
     } 
    } 

，我想啓用它當按鈕被點擊。有沒有辦法做到這一點？在您的形式

Answer 1

聲明布爾屬性，像這樣：

public Form1 
{ 
    bool TabSelectingAllowed {get;set;} 

當用戶在你現有的代碼點擊按鈕，變化值

private void button1_Click(object sender, EventArgs e) 
{ 
    TabSelectingAllowed = true; 
} 

添加額外的檢查該屬性

的價值

private void tabControl_Selecting(object sender, TabControlCancelEventArgs e) 
{ 
    if (e.TabPage == tabPage) 
    { 
     if (!TabSelectingAllowed) 
      e.Cancel = true; 
    } 
}
