GridControl(基于GridView)总结
gridControl设计器
设计器中左边导航部分Views是用于设计gridControl的布局，Columns是用于设计gridControl中列，列属性中的Name是指列明，FileName是指对应的数据库字段(实体类、BaseValue)的名称，Caption是指定列标题显示文本(类似TextBox中的Text属性)。Appearances是设计控件的外观样式。
注：options（选项）下的属性用于设置页面布局。
gridControl绑定
DevExpress中的控件绑定数据源时，都不需要调用DataBind()方法。
this.gridControl1.DataSource
=
getGoodsInfo.GetGoodsInfoDT(typeId);
注：使用泛型集合绑定数据源，在GridView中实现自动添加行时，AddNewRow()方法不起效。在获取数据行时，GetDataRow()方法报错。如果使用gridcontrol用于只呈现数据可以使用泛型集合作为数据源，如果涉及到增、删、改建议使用DataTable作为数据源，这样以上两个方法可以正常使用。
gridControl实现自动添加行
this.gridView1.AddNewRow();
//only
one
line
code
gridControl获取修改行的数据
gridControl常用函数介绍
GetDataRow()
用于获取指定索引的行。
GetFocusedRowCellValue()
获取鼠标选中行的某列值。
GetRowCellValue()
获取某行某列的值。

自定义焦点行的方法
gridView_bcode.FocusedRowHandle
=
focuseRowInt;
//通过设置GridView
的FocusedRowHandle属性
view
plaincopy
to
clipboardprint?
获取焦点行任意单元格的数据
ColumnView
cv
=
(ColumnView)gridControl_Gongzi.FocusedView;//重新获取此ID
否则无法从表头连删获取不到id
int
focusedhandle
=
cv.FocusedRowHandle;
object
rowIdObj
=
gridView1.GetRowCellValue(focusedhandle,“id“);
if
(DBNull.Value
!=
rowIdObj)
{
FocusedRow_id
=
Convert.ToInt32(rowIdObj);
}

Gridcontrol的作用笔记
girdView在第一列显示行号
调整第一列的宽度
this.gridView1.IndicatorWidth
=
40;
添加监听事件
this.gridView1.CustomDrawRowIndicator
+=
new
DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventHandler(this.gridView1_CustomDrawRowIndicator);
//在非类里这段代码
private
void
gridView1_CustomDrawRowIndicator(object
sender,DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs
e)
.{
if
(e.Info.IsRowIndicator
}
}
private
void
mnuLoad_Click(object
sender,System.EventArgs
e)
{
//
TODO:
Load
Customers
Database
db
=
null;
db
=
DatabaseFactory.CreateDatabase();
DataSet
ds
=
db.ExecuteDataSet(
CommandType.Text,“SELECT
ID,Name,Age
From
UserInfo“);
gridControl1.DataSource
=
ds.Tables[0];
设置成一次选择一行，并且不能被编辑
this.gridView1.FocusRectStyle
=
DevExpress.XtraGrid.Views.Grid.DrawFocusRectStyle.RowFocus;
this.gridView1.OptionsBehavior.Editable
=
false;
this.gridView1.OptionsSelection.EnableAppearanceFocusedCell
=
false;
设置列的标题
gridView1.Columns[0].Caption
=
“编号“;
gridView1.Columns[1].Caption
=
“名称“;
gridView1.Columns[2].Caption
=
“年龄“;
设置列的名称，便于进行分组和Foot的统计等信息显示
gridView1.Columns[0].Name
=
“ID“;
gridView1.Columns[1].Name
=
“Name“;
gridView1.Columns[2].Name
=
“Age“;
增加一个Group列进行分组
this.gridView1.GroupSummary.AddRange(new
DevExpress.XtraGrid.GridSummaryItem[]
{
new
DevExpress.XtraGrid.GridGroupSummaryItem(DevExpress.Data.SummaryItemType.Count,“ID“,null,“(Count={0})“)});
增加一个Group列进行分组
this.gridView1.GroupSummary.AddRange(new
DevExpress.XtraGrid.GridSummaryItem[]
{
new
DevExpress.XtraGrid.GridGroupSummaryItem(DevExpress.Data.SummaryItemType.Max,“Age“,null,“(Max={0})“)});
设置并制作Foot下面的统计信息
this.gridView1.GroupFooterShowMode
=
DevExpress.XtraGrid.Views.Grid.GroupFooterShowMode.VisibleAlways;
this.gridView1.OptionsView.ShowFooter
=
true;
gridView1.Columns[2].SummaryItem.DisplayFormat
=
“(Age={0})“;
gridView1.Columns[2].SummaryItem.FieldName
=
“Age“;
gridView1.Columns[2].SummaryItem.SummaryType
=
DevExpress.Data.SummaryItemType.Sum;
}
设置成cardview格式
private
void
menuItem2_Click(object
sender,EventArgs
e)
{
gridControl1.MainView
=
this.cardView1;
}
设置成GridView格式
private
void
menuItem4_Click(object
sender,EventArgs
e)
{
gridControl1.MainView
=
this.gridView1
;
}
自己模仿着写吧，相信大家很快都会成为高手的。
