C#—Dev XtraTabControl操作总结如动态增加Tab和关闭选项卡方法等

1:显示行号

找到gridview属性 点击事件 CustomDrawRowIndicator

  private void gridView1_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)
        {
            this.gridView1.IndicatorWidth = ;
            if (e.Info.IsRowIndicator && e.RowHandle >= )
            {
                e.Info.DisplayText = Convert.ToString(e.RowHandle + );
            }
 
        }

2: 隐藏GridControl的“Drag a column header here to group by that column” 也就是窗体最上边的边框.

打开设计器，找到OptionsView，往下拉设置showGroupPanel为false

C#—Dev XtraTabControl动态增加Tab和关闭选项卡方法，有需要的朋友可以参考下。

记录一下以免以后忘了

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;
                }
            }
        }
