XtraTabControl

Posted 2020-06-17

添加using DevExpress.XtraTab;

 

双击listview增加相应的tabpage，禁止重复添加：

 

 

private void listView_index_MouseDoubleClick(object sender, MouseEventArgs e)
        {
            if (listView_index.SelectedItems.Count > 0)
            {
                ListViewItem lvi = listView_index.SelectedItems[0];//得到选中的项
                string name = lvi.Text;
                //判断是否已创建过
                foreach (XtraTabPage page in xtraTabControl.TabPages)
                {
                    if (page.Text == name)
                    {
                        xtraTabControl.SelectedTabPage = page;//显示该页
                        return;
                    }
                }
                //增加tabpage
                XtraTabPage xpage = new XtraTabPage();
                xpage.Name = name;
                xpage.Text = name;
                xpage.Controls.Add(ListView_Tec);//添加要增加的控件
                xtraTabControl.TabPages.Add(xpage);
                xtraTabControl.SelectedTabPage = xpage;//显示该页
            }
        }

 

 

 

若要tabpage显示关闭按钮，把xtraTabControl的ClosePageButtonShowMode属性设为InAllTabPageHeaders；若想要首页不显示关闭按钮：

 

 

 

xtraTab_index.ShowCloseButton = DevExpress.Utils.DefaultBoolean.False;//首页不显示关闭按钮

 

 

 

添加xtraTabControl的CloseButtonClick事件：

 

 

 

private void xtraTabControl_CloseButtonClick(object sender, EventArgs e)//关闭选项卡方法
        {
            DevExpress.XtraTab.ViewInfo.ClosePageButtonEventArgs EArg = (DevExpress.XtraTab.ViewInfo.ClosePageButtonEventArgs)e;
            string name = EArg.Page.Text;//得到关闭的选项卡的text
            foreach (XtraTabPage page in xtraTabControl.TabPages)//遍历得到和关闭的选项卡一样的Text
            {
                if (page.Text == name)
                {
                    xtraTabControl.TabPages.Remove(page);
                    page.Dispose();
                    return;
                }
            }
        }

 

 

 

public int GetTabName(string value)
        {
            int count = -1;
            for (int i = 0; i < xtraTabControl1.TabPages.Count; i++)
            {
                if (xtraTabControl1.TabPages[i].Name == value)
                {
                    return i;
                }
            }
            return count;
        }

 

 

 private void button1_Click(object sender, EventArgs e)
        {
            int i = GetTabName("1");  //查询Tab控件中是否有此 name属性 
            if (i != -1)
            {
                xtraTabControl1.SelectedTabPageIndex = i;
                return;
            }

            TextBox Mytextbox = new TextBox();  //TextBox
            DevExpress.XtraTab.XtraTabPage tp = new DevExpress.XtraTab.XtraTabPage();
            tp.Controls.Add(Mytextbox);
            tp.Text = "1";
            tp.Name = "1";
            xtraTabControl1.TabPages.Add(tp);
         
            xtraTabControl1.SelectedTabPage = tp;

     }

        private void button2_Click(object sender, EventArgs e)
        {
            int i = GetTabName("2");  //查询Tab控件中是否有此 name属性
            if (i != -1)
            {
                xtraTabControl1.SelectedTabPageIndex = i;
                return;
            }

            TextBox Mytextbox = new TextBox();   //TextBox
            DevExpress.XtraTab.XtraTabPage tp1 = new DevExpress.XtraTab.XtraTabPage();
            tp1.Controls.Add(Mytextbox);
            tp1.Text = "2";
            tp1.Name = "2";
            xtraTabControl1.TabPages.Add(tp1);
            xtraTabControl1.SelectedTabPage = tp1;
        }XtraTabControl
