C#—Dev XtraTabControl操作總結如動态增加Tab和關閉頁籤方法等

1:顯示行号

找到gridview屬性 點選事件 CustomDrawRowIndicator

private void gridView1_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)
        {
            this.gridView1.IndicatorWidth = 80;
            if (e.Info.IsRowIndicator && e.RowHandle >= 0)
            {
                e.Info.DisplayText = Convert.ToString(e.RowHandle + 1);
            }

        }      

2: 隐藏GridControl的“Drag a column header here to group by that column” 也就是窗體最上邊的邊框.

打開設計器，找到OptionsView，往下拉設定showGroupPanel為false      

C#—Dev XtraTabControl動态增加Tab和關閉頁籤方法，有需要的朋友可以參考下。

記錄一下以免以後忘了

添加using DevExpress.XtraTab;

輕按兩下listview增加相應的tabpage，禁止重複添加：

private void listView_index_MouseDoubleClick(object sender, MouseEventArgs e)
        {
            if (listView_index.SelectedItems.Count > 0)
            {
                ListViewItem lvi = listView_index.SelectedItems[0];//得到選中的項
                string name = lvi.Text;
                //判斷是否已建立過
                foreach (XtraTabPage page in xtraTabControl.TabPages)
                {
                    if (page.Text == name)
                    {
                        xtraTabControl.SelectedTabPage = page;//顯示該頁
                        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;//顯示該頁
            }
        }      

若要tabpage顯示關閉按鈕，把xtraTabControl的ClosePageButtonShowMode屬性設為InAllTabPageHeaders；若想要首頁不顯示關閉按鈕：

xtraTab_index.ShowCloseButton = DevExpress.Utils.DefaultBoolean.False;//首頁不顯示關閉按鈕      

添加xtraTabControl的CloseButtonClick事件：

private void xtraTabControl_CloseButtonClick(object sender, EventArgs e)//關閉頁籤方法
        {
            DevExpress.XtraTab.ViewInfo.ClosePageButtonEventArgs EArg = (DevExpress.XtraTab.ViewInfo.ClosePageButtonEventArgs)e;
            string name = EArg.Page.Text;//得到關閉的頁籤的text
            foreach (XtraTabPage page in xtraTabControl.TabPages)//周遊得到和關閉的頁籤一樣的Text
            {
                if (page.Text == name)
                {
                    xtraTabControl.TabPages.Remove(page);
                    page.Dispose();
                    return;
                }
            }
        }
