104、GridControl删除一行
gdvFlts.DeleteRow(i);
103、GridControl中添加Button
RunDesigner，添加一列，设置对应字段FiledName，ColumnEdit选择ButtonEdit，此时默认风格像下拉框，需调整属性：
在In-placeEditor中，选择该控件，设置TextEditStyle为HideTextEditor
设置按钮上的预设图标：Buttons-Kind属性将默认的Ellipsis（省略号）设为Glyph（空白），同时将Caption设为需要显示的文字
此时按钮轮廓不明显，将appearance的ButonsStyle改成NoBorder
102、更改数据绑定后的列标题或隐藏列标题
更改：gdvPassbyArl.Columns["选择"].Caption="更改"; //但不能设为空为nul，无效
隐藏列标题：gdvPassbyArl.Columns["选择"].OptionsColumn.ShowCaption = false;
101、获取/设置某单元格内容：GetRowCellValue、SetRowCellValue(i, "选择", checkEdit1.Checked);
100、GridControl选中所有行
gdvPassbyArl.SelectRows(0,gdvPassbyArl.RowCount-1);//一句话选中所有行，或任意多行
gdvPassbyArl.SelectRow(10);//选中某行
DEV控件在工具箱中消失处理方法
开始-->程序-->Developer Express v2009 vol 3（依据版本不同）-->Components-->Tools-->ToolboxCreator
1、点击一行选择完整一行
Run Designer->View->OptionsBehavior->EditorShowMode 设置为：Click
Run Designer->View->OptionsSelection.EnableAppearanceFocusedCell = false;
2、设置行不可编辑
Run Designer->View->OptionsBehavior->Editable 设置为：false
但这样也无法拷贝数据了，最好是上面Editable保持true，设置：
Run Designer->View->OptionsBehavior->ReadOnly 设置为：true
3、如何禁用GridControl中单击列弹出右键菜单
Run Design->OptionsMenu->EnableColumnMenu 设置为：false
Run Design->OptionsMenu->EnableFooterMenu 设置为：false
4、隐藏GridControl的GroupPanel表头
Run Design->OptionsView->ShowGroupPanel 设置为：false
取消压缩表格在窗体内完整显示(不出现横向滚动条)
Run Design->OptionsView->OptionsView.ColumnAutoWidth = false;
5、如何禁用GridControl中列头的过滤器
Run Design->OptionsCustomization->AllowFilter 设置为：false
OptionsView->ShowAutoFilterRow:true 显示顶端过滤行
6、如何在行头部显示行号？
this.gridView1.IndicatorWidth = 40;
private void gridView1_CustomDrawRowIndicator(object sender, RowIndicatorCustomDrawEventArgs e)
{
//最顶上一行显示总行数
if ( e.Info.Kind == DevExpress.Utils.Drawing.IndicatorKind.Header )
{
e.Info.DisplayText = ((DevExpress.XtraGrid.Views.Grid.GridView)sender).DataRowCount.ToString();
}
if (e.Info.IsRowIndicator && e.RowHandle>=0)
e.Info.DisplayText = (e.RowHandle + 1).ToString();
}
7、得到当前选定记录某字段的值
sValue= gridView1.GetDataRow(gridView1.FocusedRowHandle)[FieldName].ToString();
或string ss = gridView1.GetRowCellValue(0, gridView1.Columns[0]);
8、不显示MasterDetailView
gridView1.OptionsDetail.EnableMasterViewMode=false;
9、设某一列文字和标题居中显示
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动筛选功能(Filter)
gridView1.Columns[0].OptionsFilter.AllowAutoFilter = false;
gridView1.Columns[0].OptionsFilter.AllowFilter =false;
gridView1.Columns[0].OptionsFilter.ImmediateUpdateAutoFilter =false;
15、如何让各列头禁止移动？
设置 gridView1.OptionsCustomization.AllowColumnMoving = false;
16、如何让各列头禁止排序？
设置 gridView1.OptionsCustomization.AllowSort = false;
17、如何禁止各列头改变列宽？
设置 gridView1.OptionsCustomization.AllowColumnResizing = false;
11、设置冻结列(左冻结)
gridView1.Columns[0].Fixed= DevExpress.XtraGrid.Columns.FixedStyle.Left;
12、得到/设置单元格数据
string ss=gridView1.GetRowCellDisplayText(0,gridView1.Columns[0]);
string ss = gridView1.GetRowCellValue(0, gridView1.Columns[0]);
13、设置列宽自动适应文字长短
gridView1.BestFitColumns();
gridView1.BestFitMaxRowCount = 500; //对行数过多时，避免调整时间过长，根据前多少行来判断每列最佳宽度
14、设置gridview控件的字体
designer-views-外观-appearance-row-font中设置
15、隐藏行头列
gdv_point.OptionsView.ShowIndicator = false; //取消行头列
16、更改某一行的颜色，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; //因为前面已设置了奇偶行背景色，所以这里如果再设置某行背景色无效
}
17、更改某一单元格颜色，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、获取或设置某一单元格文字
DataRow dr = gdv_point.GetDataRow(gdv_point.FocusedRowHandle); //与DataTable的一样
dr[3] = "456";
19、设置奇偶行颜色后就不能再更改某行的背景色，解决方法，不设奇偶色，在RowStyle事件中绘制，同时设置某行颜色
private void gdv_point_RowStyle(object sender, DevExpress.XtraGrid.Views.Grid.RowStyleEventArgs e)
{
if (e.RowHandle < 0) return; //还未加载数据
if (e.RowHandle % 2 == 0)
e.Appearance.BackColor = Color.FromArgb(255, 255, 240); // 设置偶数行颜色
else
e.Appearance.BackColor = Color.FromArgb(255, 255, 255); // 设置奇数行颜色默认也是白色 可以省略
if (gdv_point.GetDataRow(e.RowHandle)["当前状态"].ToString().Trim() != "")
e.Appearance.BackColor = Color.FromArgb(255, 0, 0);
}
20、(2016.2.14情人节，初七)设置某行为顶端第一显示行，即视图滚动到指定行:TopRowIndex(没有下面的方法好)
int oldtop = parentFrm.gdv_point.TopRowIndex;//获取原来的最顶行
int oldfocusrow = parentFrm.gdv_point.FocusedRowHandle;
parentFrm.butquery_Click(null,null);//重新执行查询
parentFrm.gdv_point.TopRowIndex = oldtop;//将最顶行设回原来值，如果原来值超出总行数也不会报错，会将最顶行设为最大可能值。
parentFrm.gdv_point.FocusedRowHandle = oldfocusrow; //超出最大行数也不会报错
21、根据某cell的值使界面定位并高亮选择该行。LocateByDisplayText（小朱提供方法 2016.2.19）
gdv_point.FocusedRowHandle = gdv_point.LocateByDisplayText(0, gdv_point.Columns["ID"], pid);
补充，此方法后必须跟
gdv_point.ClearSelection();//清除默认选择行
gdv_point.SelectRow(gdv_point.FocusedRowHandle); //一定要有这句，否则该行不会高亮
22、时间类型默认在gridview中只能显示年月日，如果要显示时分秒，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一定要大写
e.Column.DisplayFormat.FormatType = DevExpress.Utils.FormatType.DateTime; //这句必须要
//e.Column.DisplayFormat.FormatString = "{0:N2}"; //数字格式化
//e.Column.DisplayFormat.FormatType = DevExpress.Utils.FormatType.Numeric;
}
23、整个gridview设为可编辑后，使符合某些条件的行或列不可编辑
private void gdv_pdfpnt_ShowingEditor(object sender, CancelEventArgs e)
{
if (gdv_pdfpnt.FocusedColumn.AbsoluteIndex == 1)
e.Cancel = true;
}
24、显示自动过滤行
OptionView：ShowAutoFilterRow 显示自动过滤行
25、让输入值自动大写
RepositoryItemTextEdit editor = (RepositoryItemTextEdit)gdc_pdfpnt.RepositoryItems.Add("TextEdit");
editor.CharacterCasing = CharacterCasing.Upper;
gdv_pdfpnt.Columns[3].ColumnEdit = editor;
26、更换绑定的DataTable
gdv_pnt.Columns.Clear();
gdc_pnt.DataSource = dt;
gdv_pnt.RefreshData();
27、多选多行模式获取所有选择行
List<int> selrows = gdv_apoint.GetSelectedRows().ToList(); //多选
28 GridControl控件中显示自定义控件的方法//2016.4.16
添加MouseDown事件,与RowCellClick事件的区别在于RowCellClick只能处理可编辑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);
}
//获取点击cell的位置并显示控件
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) //限制鼠标事件为左键单击
{
gdv_pdfpnt.FocusedRowHandle = hitInfo.RowHandle; //关键！触发此事件时，dev控件还没来得及将当前行切换到点击行，这里做强制切换，否则会出现混乱。
GridCellInfo cellInfo = viewInfo.GetGridCellInfo(hitInfo);
Rectangle rect = cellInfo.Bounds;
int left = gdc_pdfpnt.Left+rect.Left; //rect 只是客户区坐标，要转化为屏幕绝对坐标
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 != "") //设置弹出控件初始值
uC_TypeSelector.RefFormValue(val); //将cell值初始化类型选择框，每次改变uc控件值的同时，也会触发控件回调函数往该界面上写回值，所以这里其实还执行了一次界面赋值
else
uC_TypeSelector.RefFormValue(" ");
}
else
uC_TypeSelector.Visible = false;
}
29、自动添加行号的方法：2016.5.9
1、开启显示标记列 gdv_point.OptionsView.ShowIndicator = true；默认就是开的
2、设置标记列列宽
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、添加双击事件添加gdv_pro_MouseDown事件 2016.5.12
可以将gdv_point.OptionsBehavior.Editable = false;也可不设置
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、根据界面宽度自动设置列宽模式 2016.5.13
在界面或某控件的SizeChang事件中执行此函数
public static void BestFitGridViewColumnsWith( DevExpress.XtraGrid.Views.Grid.GridView gdv )
{
//先设置最小列宽
gdv.BestFitColumns();
//获取所有列总最小宽度
int tt = 0;
for (int i = 0; i < gdv.Columns.Count; i++)
tt += gdv.CalcColumnBestWidth(gdv.Columns[i]);
//如果有指示列，加上其宽度
if (gdv.OptionsView.ShowIndicator)
tt += gdv.IndicatorWidth;
//根据宽度调整列显示模式
if (tt < gdv.ViewRect.Width)
gdv.OptionsView.ColumnAutoWidth = true;
else
gdv.OptionsView.ColumnAutoWidth = false;
}
32、设置单元格中实现换行2016.9.1
首先，查询语句中用CHR(10)分行符连接显示内容，如：zx_org||CHR(10)||zx_cut 走向，或者在代码中用 或 或 连接两string
绑定数据后用
DevExpress.XtraEditors.Repository.RepositoryItemMemoEdit x = new DevExpress.XtraEditors.Repository.RepositoryItemMemoEdit();
gdv_zxnotmatch.Columns["走向"].ColumnEdit = x;
gdv_zxnotmatch.OptionsView.RowAutoHeight = true;
可实现分行显示
33、单独设置某些cell的字体等风格在事件CustomDrawCell中实现2016.10.31
private void gdv_point_CustomDrawCell(object sender, DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e)
{
if(e.Column.Name=="col报告类型")
{
if (e.CellValue.ToString() == "△")
e.Appearance.Font = new Font("宋体", 9f);
}
}
设置主表、从表嵌套显示，主表行前出现+号，点击显示满足关联关系的从表数据
1、在主view新添加一级level主，从视图分别为gridView1和gridView2
2、新建Dataset将主视图、从视图对应的两张datatable添加进去，并设置这两张表的公共字段建立关联，即主键和外键
3、将此Dataset的具有主键的Table赋给gridConcrol的DataSource即可
DataSet ds = new DataSet();
var t1 = DBFactorySingleton.GetInstance().Factory.GetDataTable(string.Format(@"select txt_name 名称, code_id 识别,significant_point_id ID from {0}.vor", AisLogical.dbuser)).Copy(); //加copy的原因是原datatable已经属于一个dataset
t1.TableName = "t1"; //如果不对table命名，两次添加的table都会叫默认的表名data，第二张表就添加不进此dataset
ds.Tables.Add(t1); //主表显示内容
var t2 = DBFactorySingleton.GetInstance().Factory.GetDataTable(string.Format(@"select significant_point_id ID, geo_lat 纬度,geo_long 经度,val_freq||uom_freq 频率,val_mag_var 磁差 from {0}.vor", AisLogical.dbuser)).Copy();
t2.TableName = "t2";
ds.Tables.Add(t2);//子表显示内容
////将子表与主表的公共字段作为主键和外键，目的为了建立关系，由主表带出子表
DataColumn keyColumn = ds.Tables["t1"].Columns["id"];
DataColumn foreignKeyColoumn = ds.Tables["t2"].Columns["id"];
//建立关系, 此关系名称NAIP会默认显示在子表表头，可通过设置主表的OptionsDetail.ShowDetailTabs = false;来隐藏名称
ds.Relations.Add("NAIP", keyColumn, foreignKeyColoumn);
gridControl1.DataSource = ds.Tables["t1"]; //将具有主键的datatable赋给整个控件的DataSource完成主、从表绑定
////////////////////////////////////////////////

gdv_point.Appearance.EvenRow.BackColor = Color.FromArgb(255, 255, 240); // 设置偶数行颜色
gdv_point.Appearance.Row.Font = new System.Drawing.Font("微软雅黑", 10.5f); //表内字体
gdv_point.Appearance.HeaderPanel.Font = new System.Drawing.Font("仿宋", 13f, FontStyle.Bold);//表头字体
gdv_point.ColumnPanelRowHeight = 35; //表头面板高度
gdv_point.RowHeight = 30; //表格行高
gdv_point.Appearance.FocusedRow.BackColor = Color.FromArgb(255, 240, 151); //选中行背景色
gdv_point.Appearance.FocusedRow.ForeColor = Color.Black; //选中行前景色
gdv_point.Appearance.HideSelectionRow.BackColor = Color.White; //失去焦点是选中行前景色
gdv_point.Appearance.HideSelectionRow.ForeColor = Color.Black;//失去焦点是选中行背景色
//3、行选模式
gdv_point.OptionsBehavior.EditorShowMode = DevExpress.Utils.EditorShowMode.Click; //设置整行选择
gdv_point.OptionsBehavior.ReadOnly = true; //不可编辑
gdv_point.OptionsSelection.EnableAppearanceFocusedCell = false; //取消选中时单元格高亮
//4、操作
gdv_point.OptionsMenu.EnableColumnMenu = false; //禁用列名右键弹出菜单
gdv_point.OptionsMenu.EnableFooterMenu = false;//禁用脚注右键弹出菜单
gdv_point.OptionsView.ShowGroupPanel = false;//禁用拖表头group面板
//gdv_point.OptionsCustomization.AllowFilter = false; //禁用列头筛选
gdv_point.OptionsView.ColumnAutoWidth = false;//禁用自动列宽，恢复横向滚动条
//5、列宽优化

gdv_point.BestFitMaxRowCount = 500; //根据前多少行来判断每列最佳宽度
gdv_point.OptionsDetail.ShowDetailTabs = false;//隐藏从表的表头标签
gdv_point.OptionsView.ShowIndicator = false; //取消行头列
