DEV控件在工具箱中消失處理方法
開始-->程序-->Developer Express v2009 vol 3（依據版本不同）-->Components-->Tools-->ToolboxCreator
1、點擊一行選擇完整一行
Run Designer->View->OptionsBehavior->EditorShowMode 設置爲：Click
Run Designer->View->OptionsSelection.EnableAppearanceFocusedCell = false;
2、設置行不可編輯
Run Designer->View->OptionsBehavior->Editable 設置爲：false
但這樣也無法拷貝數據了，最好是上面Editable保持true，設置：
Run Designer->View->OptionsBehavior->ReadOnly 設置爲：true
3、如何禁用GridControl中單擊列彈出右鍵菜單
Run Design->OptionsMenu->EnableColumnMenu 設置爲：false
Run Design->OptionsMenu->EnableFooterMenu 設置爲：false
4、隱藏GridControl的GroupPanel表頭
Run Design->OptionsView->ShowGroupPanel 設置爲：false
取消壓縮表格在窗體內完整顯示(不出現橫向滾動條)
Run Design->OptionsView->OptionsView.ColumnAutoWidth = false;
5、如何禁用GridControl中列頭的過濾器
Run Design->OptionsCustomization->AllowFilter 設置爲：false
OptionsView->ShowAutoFilterRow:true 顯示頂端過濾行
6、如何在行頭部顯示行號？
this.gridView1.IndicatorWidth = 40;
private void gridView1_CustomDrawRowIndicator(object sender, RowIndicatorCustomDrawEventArgs e)
{
if (e.Info.IsRowIndicator && e.RowHandle>=0)
e.Info.DisplayText = (e.RowHandle + 1).ToString();
}
7、得到當前選定記錄某字段的值
sValue= gridView1.GetDataRow(gridView1.FocusedRowHandle)[FieldName].ToString();
8、不顯示MasterDetailView
gridView1.OptionsDetail.EnableMasterViewMode=false;
9、設某一列文字和標題居中顯示
gridView1.Columns[0].AppearanceHeader.TextOptions.HAlignment =DevExpress.Utils.HorzAlignment.Center;
gridView1.Columns[0].AppearanceCell.TextOptions.HAlignment =DevExpress.Utils.HorzAlignment.Center;
10、去掉某一列上面的自動篩選功能(Filter)
gridView1.Columns[0].OptionsFilter.AllowAutoFilter = false;
gridView1.Columns[0].OptionsFilter.AllowFilter =false;
gridView1.Columns[0].OptionsFilter.ImmediateUpdateAutoFilter =false;
11、設置凍結列(左凍結)
gridView1.Columns[0].Fixed= DevExpress.XtraGrid.Columns.FixedStyle.Left;
12、得到/設置單元格數據
string ss=gridView1.GetRowCellDisplayText(0,gridView1.Columns[0]);
string ss = gridView1.GetRowCellValue(0, gridView1.Columns[0]);
13、設置列寬自動適應文字長短
gridView1.BestFitColumns();
gridView1.BestFitMaxRowCount = 500; //對行數過多時，避免調整時間過長，根據前多少行來判斷每列最佳寬度
14、設置gridview控件的字體
designer-views-外觀-appearance-row-font中設置
15、隱藏行頭列
gdv_point.OptionsView.ShowIndicator = false; //取消行頭列
16、更改某一行的顏色，添加事件
private void gdv_point_RowStyle(object sender, DevExpress.XtraGrid.Views.Grid.RowStyleEventArgs e)
{
DataRow dr = gdv_point.GetDataRow(e.RowHandle);
if (dr != null && e.RowHandle==2)
e.Appearance.ForeColor = Color.Red; //因爲前面已設置了奇偶行背景色，所以這裏如果再設置某行背景色無效
}
17、更改某一單元格顏色，添加事件
private void gdv_point_RowCellStyle(object sender, DevExpress.XtraGrid.Views.Grid.RowCellStyleEventArgs e)
{
if (e.RowHandle == 4 && e.Column.AbsoluteIndex == 4) //e.Column.FieldName == "FIR";
e.Appearance.ForeColor = Color.Green;
}
18、獲取或設置某一單元格文字
DataRow dr = gdv_point.GetDataRow(gdv_point.FocusedRowHandle); //與DataTable的一樣
dr[3] = "456";
19、設置奇偶行顏色後就不能再更改某行的背景色，解決方法，不設奇偶色，在RowStyle事件中繪製，同時設置某行顏色
private void gdv_point_RowStyle(object sender, DevExpress.XtraGrid.Views.Grid.RowStyleEventArgs e)
{
if (e.RowHandle < 0) return; //還未加載數據
if (e.RowHandle % 2 == 0)
e.Appearance.BackColor = Color.FromArgb(255, 255, 240); // 設置偶數行顏色
else
e.Appearance.BackColor = Color.FromArgb(255, 255, 255); // 設置奇數行顏色默認也是白色 可以省略
if (gdv_point.GetDataRow(e.RowHandle)["當前狀態"].ToString().Trim() != "")
e.Appearance.BackColor = Color.FromArgb(255, 0, 0);
}
20、設置某行爲頂端第一顯示行，即視圖滾動到指定行:TopRowIndex(沒有下面的方法好)
int oldtop = parentFrm.gdv_point.TopRowIndex;//獲取原來的最頂行
int oldfocusrow = parentFrm.gdv_point.FocusedRowHandle;
parentFrm.butquery_Click(null,null);//重新執行查詢
parentFrm.gdv_point.TopRowIndex = oldtop;//將最頂行設回原來值，如果原來值超出總行數也不會報錯，會將最頂行設爲最大可能值。
parentFrm.gdv_point.FocusedRowHandle = oldfocusrow; //超出最大行數也不會報錯
21、根據某cell的值使界面定位並高亮選擇該行。LocateByDisplayText
gdv_point.FocusedRowHandle = gdv_point.LocateByDisplayText(0, gdv_point.Columns["ID"], pid);
22、時間類型默認在gridview中只能顯示年月日，如果要顯示時分秒，需要在RowCellStyle事件中添加
if (e.Column.ColumnType.ToString() == "System.DateTime")
{
e.Column.DisplayFormat.FormatString = "yyyy-MM-dd HH:mm:ss"; //MM和HH一定要大寫
e.Column.DisplayFormat.FormatType = DevExpress.Utils.FormatType.DateTime; //這句必須要
//e.Column.DisplayFormat.FormatString = "{0:N2}"; //數字格式化
//e.Column.DisplayFormat.FormatType = DevExpress.Utils.FormatType.Numeric;
}
23、整個gridview設爲可編輯後，使符合某些條件的行或列不可編輯
private void gdv_pdfpnt_ShowingEditor(object sender, CancelEventArgs e)
{
if (gdv_pdfpnt.FocusedColumn.AbsoluteIndex == 1)
e.Cancel = true;
}
24、顯示自動過濾行
OptionView：ShowAutoFilterRow 顯示自動過濾行
25、讓輸入值自動大寫
RepositoryItemTextEdit editor = (RepositoryItemTextEdit)gdc_pdfpnt.RepositoryItems.Add("TextEdit");
editor.CharacterCasing = CharacterCasing.Upper;
gdv_pdfpnt.Columns[3].ColumnEdit = editor;
26、更換綁定的DataTable
gdv_pnt.Columns.Clear();
gdc_pnt.DataSource = dt;
gdv_pnt.RefreshData();
27、多行模式獲取所有選擇行
List<int> selrows = gdv_apoint.GetSelectedRows().ToList(); //多行選擇
28 GridControl控件中顯示自定義控件的方法//2016.4.16
添加MouseDown事件,與RowCellClick事件的區別在於RowCellClick只能處理可編輯Cell
private void gdv_pdfpnt_MouseDown(object sender, MouseEventArgs e)
{
DevExpress.XtraGrid.Views.Grid.ViewInfo.GridHitInfo hinfo = gridView1.CalcHitInfo(new Point(e.X, e.Y));
if (hinfo.InRowCell && e.Button == MouseButtons.Left && e.Clicks == 1)
{
gridView1.FocusedRowHandle = hinfo.RowHandle;
DevExpress.XtraGrid.Views.Grid.GridView view = sender as DevExpress.XtraGrid.Views.Grid.GridView;
DevExpress.XtraGrid.Views.Grid.ViewInfo.GridViewInfo viewinfo = view.GetViewInfo() as DevExpress.XtraGrid.Views.Grid.ViewInfo.GridViewInfo;
DevExpress.XtraGrid.Views.Grid.ViewInfo.GridCellInfo df = viewinfo.GetGridCellInfo(hinfo);
Rectangle rct = df.Bounds;
simpleButton1.Bounds = new Rectangle(rct.Left + gridControl1.Left, rct.Top + gridControl1.Top, rct.Width, rct.Height);
}
//獲取點擊cell的位置並顯示控件
GridView view = sender as GridView;
GridViewInfo viewInfo = view.GetViewInfo() as GridViewInfo;
GridHitInfo hitInfo = view.CalcHitInfo(e.Location);
if (hitInfo.InRowCell && hitInfo.Column.AbsoluteIndex == gdv_pdfpnt.Columns.Count - 1 && e.Button == MouseButtons.Left && e.Clicks == 1) //限制鼠標事件爲左鍵單擊
{
gdv_pdfpnt.FocusedRowHandle = hitInfo.RowHandle; //關鍵！觸發此事件時，dev控件還沒來得及將當前行切換到點擊行，這裏做強制切換，否則會出現混亂。
GridCellInfo cellInfo = viewInfo.GetGridCellInfo(hitInfo);
Rectangle rect = cellInfo.Bounds;
int left = gdc_pdfpnt.Left+rect.Left; //rect 只是客戶區座標，要轉化爲屏幕絕對座標
int top = gdc_pdfpnt.Top+rect.Top+3;
uC_TypeSelector.Left = left;
uC_TypeSelector.Top = top;
uC_TypeSelector.Visible = true;
string val=gdv_pdfpnt.GetDataRow(hitInfo.RowHandle)[hitInfo.Column.AbsoluteIndex].ToString();
if (val != "") //設置彈出控件初始值
uC_TypeSelector.RefFormValue(val); //將cell值初始化類型選擇框，每次改變uc控件值的同時，也會觸發控件回調函數往該界面上寫回值，所以這裏其實還執行了一次界面賦值
else
uC_TypeSelector.RefFormValue(" ");
}
else
uC_TypeSelector.Visible = false;
}
29、自動添加行號的方法：
1、開啓顯示標記列 gdv_point.OptionsView.ShowIndicator = true；默認就是開的
2、設置標記列列寬
3、添加事件
private void gdv_pro_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)
{
//e.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far;
if (e.Info.IsRowIndicator)
{
if (e.RowHandle >= 0)
{
e.Info.DisplayText = (e.RowHandle + 1).ToString();
}
}
}
30、添加雙擊事件添加gdv_pro_MouseDown事件
可以將gdv_point.OptionsBehavior.Editable = false;也可不設置
DevExpress.XtraGrid.Views.Grid.ViewInfo.GridHitInfo hInfo = gdv_pro.CalcHitInfo(new Point(e.X, e.Y));
if (hInfo.InRow && e.Button == MouseButtons.Left && e.Clicks == 2)
31、根據界面寬度自動設置列寬模式
在界面或某控件的SizeChang事件中執行此函數
public static void BestFitGridViewColumnsWith( DevExpress.XtraGrid.Views.Grid.GridView gdv )
{
//先設置最小列寬
gdv.BestFitColumns();
//獲取所有列總最小寬度
int tt = 0;
for (int i = 0; i < gdv.Columns.Count; i++)
tt += gdv.CalcColumnBestWidth(gdv.Columns[i]);
//如果有指示列，加上其寬度
if (gdv.OptionsView.ShowIndicator)
tt += gdv.IndicatorWidth;
//根據寬度調整列顯示模式
if (tt < gdv.ViewRect.Width)
gdv.OptionsView.ColumnAutoWidth = true;
else
gdv.OptionsView.ColumnAutoWidth = false;
}
32、設置單元格中實現換行
首先，查詢語句中用CHR(10)分行符連接顯示內容，如：zx_org||CHR(10)||zx_cut 走向
綁定數據後用
DevExpress.XtraEditors.Repository.RepositoryItemMemoEdit x = new DevExpress.XtraEditors.Repository.RepositoryItemMemoEdit();
gdv_zxnotmatch.Columns["走向"].ColumnEdit = x;
gdv_zxnotmatch.OptionsView.RowAutoHeight = true;
可實現分行顯示
設置主表、從表嵌套顯示，主錶行前出現+號，點擊顯示滿足關聯關係的從表數據
1、在主view新添加一級level主，從視圖分別爲gridView1和gridView2
2、新建Dataset將主視圖、從視圖對應的兩張datatable添加進去，並設置這兩張表的公共字段建立關聯，即主鍵和外鍵
3、將此Dataset的具有主鍵的Table賦給gridConcrol的DataSource即可
DataSet ds = new DataSet();
var t1 = DBFactorySingleton.GetInstance().Factory.GetDataTable(string.Format(@"select txt_name 名稱, code_id 識別,significant_point_id ID from {0}.vor", AisLogical.dbuser)).Copy(); //加copy的原因是原datatable已經屬於一個dataset
t1.TableName = "t1"; //如果不對table命名，兩次添加的table都會叫默認的表名data，第二張表就添加不進此dataset
ds.Tables.Add(t1); //主表顯示內容
var t2 = DBFactorySingleton.GetInstance().Factory.GetDataTable(string.Format(@"select significant_point_id ID, geo_lat 緯度,geo_long 經度,val_freq||uom_freq 頻率,val_mag_var 磁差 from {0}.vor", AisLogical.dbuser)).Copy();
t2.TableName = "t2";
ds.Tables.Add(t2);//子表顯示內容
////將子表與主表的公共字段作爲主鍵和外鍵，目的爲了建立關係，由主錶帶出子表
DataColumn keyColumn = ds.Tables["t1"].Columns["id"];
DataColumn foreignKeyColoumn = ds.Tables["t2"].Columns["id"];
//建立關係, 此關係名稱NAIP會默認顯示在子表表頭，可通過設置主表的OptionsDetail.ShowDetailTabs = false;來隱藏名稱
ds.Relations.Add("NAIP", keyColumn, foreignKeyColoumn);
gridControl1.DataSource = ds.Tables["t1"]; //將具有主鍵的datatable賦給整個控件的DataSource完成主、從表綁定
////////////////////////////////////////////////
//完全用代碼實現Grid控件設置
#region DevGridControl控件設置
///////////////////////////////////////////////////////////////////////
//1添加行號
//gdv_point.IndicatorWidth = 50; //最好不要顯示此列
//添加事件顯示行號
//private void gdv_point_CustomDrawRowIndicator(object sender, RowIndicatorCustomDrawEventArgs e)
//{
// if (e.Info.IsRowIndicator && e.RowHandle>=0)
// e.Info.DisplayText = (e.RowHandle + 1).ToString();
// e.Info.ImageIndex = -1; //不顯示小三角
//}
//2外觀設置可設置自帶的4種風格，可再做調整
gdc_point.LookAndFeel.UseDefaultLookAndFeel = false;
gdc_point.LookAndFeel.SkinName = "Caramel";
//gdc_point.LookAndFeel.SkinName = "Lilian";
//gdc_point.LookAndFeel.SkinName = "iMaginary";
//gdc_point.LookAndFeel.SkinName = "Money Twins";
gdv_point.OptionsView.EnableAppearanceOddRow = true; // 允許設置奇數行
gdv_point.OptionsView.EnableAppearanceEvenRow = true; // 允許設置偶數行
gdv_point.Appearance.OddRow.BackColor = Color.FromArgb(255, 255, 255); // 設置奇數行顏色默認也是白色 可以省略
gdv_point.Appearance.EvenRow.BackColor = Color.FromArgb(255, 255, 240); // 設置偶數行顏色
gdv_point.Appearance.Row.Font = new System.Drawing.Font("微軟雅黑", 10.5f); //表內字體
gdv_point.Appearance.HeaderPanel.Font = new System.Drawing.Font("仿宋", 13f, FontStyle.Bold);//表頭字體
gdv_point.ColumnPanelRowHeight = 35; //表頭面板高度
gdv_point.RowHeight = 30; //表格行高
gdv_point.Appearance.FocusedRow.BackColor = Color.FromArgb(255, 240, 151); //選中行背景色
gdv_point.Appearance.FocusedRow.ForeColor = Color.Black; //選中行前景色
gdv_point.Appearance.HideSelectionRow.BackColor = Color.White; //失去焦點是選中行前景色
gdv_point.Appearance.HideSelectionRow.ForeColor = Color.Black;//失去焦點是選中行背景色
//3、行選模式
gdv_point.OptionsBehavior.EditorShowMode = DevExpress.Utils.EditorShowMode.Click; //設置整行選擇
gdv_point.OptionsBehavior.ReadOnly = true; //不可編輯
gdv_point.OptionsSelection.EnableAppearanceFocusedCell = false; //取消選中時單元格高亮
//4、操作
gdv_point.OptionsMenu.EnableColumnMenu = false; //禁用列名右鍵彈出菜單
gdv_point.OptionsMenu.EnableFooterMenu = false;//禁用腳註右鍵彈出菜單
gdv_point.OptionsView.ShowGroupPanel = false;//禁用拖表頭group面板
//gdv_point.OptionsCustomization.AllowFilter = false; //禁用列頭篩選
gdv_point.OptionsView.ColumnAutoWidth = false;//禁用自動列寬，恢復橫向滾動條
//5、列寬優化
//每次綁定數據後要執行gdv_point.BestFitColumns(); 來優化每列寬度
gdv_point.BestFitMaxRowCount = 500; //根據前多少行來判斷每列最佳寬度
gdv_point.OptionsDetail.ShowDetailTabs = false;//隱藏從表的表頭標籤
gdv_point.OptionsView.ShowIndicator = false; //取消行頭列
