Dev组件包功能强大，但说明性的文档太少也给我们使用带来的很大的障碍。最近项目需要使用Dev控件，把点点滴滴记录在这里备忘。
1，适当调整列宽（当列很多时）
gridView1.OptionsView.ColumnAutoWidth= false;
gridView1. BestFitColumns();
2,多选
gridView1 .OptionsSelection.MultiSelect = true;
gridView1 .OptionsSelection.MultiSelectMode = DevExpress.XtraGrid.Views.Grid.GridMultiSelectMode.RowSelect;
3，添加复选框列
添加一列,FieldName为 "check"，将ColumnEdit 设置为 复选框 样式。
将要绑定的DataTable添加列 "check",Type 为 bool。
绑定DataTable到GridControl。
获取： string value = gridview.GetDataRow(i)["check"].toString();
value == "true" || "" ("false")
4,GroupPanel设置
gridView1.GroupPanelText="title";
gridView1.OptionsView.ShowGroupPanel=false;
gridView1.OptionsView.ShowGroupPanel = false;
取消显示头部的pannel
gridView1.OptionsView.EnableAppearanceOddRow = true;
奇偶显示
选中变色
gridView2.Appearance.FocusedRow.BackColor = System.Drawing.Color.RoyalBlue;
设成只读
1. gridView1.OptionsBehavior.Editable = false;
2. gridView1.Columns[5].readonly= true;
左边表头去掉
gridView1.Options.OptionView .ShowIndicator=False;
--------------------------------------------------------------------------------------------------------------------------------------------------------
取值1.
private void gridControl1_DoubleClick(object sender, System.EventArgs e)
{
//双击弹出异常日志描述
if (this.gridView1.RowCount > 0)
{
int[] a=this.gridView1.GetSelectedRows();
string str_GUID=this.gridView1.GetRowCellValue(a[0],"Ex_No").ToString();//获得异常编号
MessageBox.Show(str_GUID);
frmExceptionLogDesc dlg=new frmExceptionLogDesc();
dlg.Text = "异常日志查看";
dlg.ShowDialog();
}
}
取值2.
private void gridControl1_DoubleClick(object sender, EventArgs e)
{
// DB.Help.UserInfo model = (sender as DevExpress.XtraGrid.GridControl).DataSource as DB.Help.UserInfo;
if (this.gridView1.RowCount > 0)
{
int[] selectRow = this.gridView1.GetSelectedRows();
DB.Help.UserInfo model = gridView1.GetRow(selectRow[0]) as DB.Help.UserInfo;
// string UserName = this.gridView1.GetRowCellValue(selectRow[0], "UserName").ToString();//获得异常编号
UserInfo ui = new UserInfo();
ui.UserInfoModel = model;
ui.Show();
}
}
补充：
(6)barManager的具体设置
在增加了barManager控件以后，在[Click Here to add MainMenu] [Click Here to Tool Bar]里面选择[Click Here to Tool Bar] 填写需要新增的工具栏按钮。
进入Designer 里面，选择ToolBars ->Custom 1->OptionsBar 里面进行如下设置：
AllowQuickCustomization=false
DrawDragBorder=false
RotateWhenVertical=false
UseWholeRow=True
以上4项进行初始化设置
(7) 在DataGrid 里面增加状态栏
首先在BarManager里面增加StaticText 把新增的barStaticItem 的AutoSize 设置为Spring
然后，编写以下代码：
private void StateCote()
{
if (gridView1.RowCount!=0)
{
int a=this.gridView1.RowCount;
barStaticItem1.Caption="当前共有记录："+a.ToString();
int[] b=this.gridView1.GetSelectedRows();
b[0]+=1;
barStaticItem2.Caption="当前选中："+b[0].ToString();
}
else
{
barStaticItem1.Caption="当前共有记录：";
barStaticItem2.Caption="当前选中：";
}
}
private void gridControl1_Click(object sender, System.EventArgs e)
{
StateCote();
}
private void gridView1_FocusedRowChanged(object sender, DevExpress.XtraGrid.Views.Base.FocusedRowChangedEventArgs e)
{
StateCote();
}
(8) DateTable 填充DataGrid
这里需要引用：
using DevExpress.Utils;
/**//// <summary>
/// 根据DataTable 填充DataGrid
/// </summary>
/// <param name="dt"></param>
private void DisposeDataGrid(DataTable dt)
{
//标题居中
gridView1.Appearance.HeaderPanel.TextOptions.HAlignment =HorzAlignment.Center;
this.gridControl1.DataSource = dt;
gridView1.Columns[0].Visible = false;//异常日志GUID
gridView1.Columns[1].Visible = false;//通行编号
gridView1.Columns[2].Visible = false;//通道编号
gridView1.Columns[3].Caption = "通道名称";
gridView1.Columns[3].Width = 100;
gridView1.Columns[4].Caption = "卡号";
gridView1.Columns[4].Width = 100;
gridView1.Columns[5].Caption = "持卡人姓名";
gridView1.Columns[5].Width = 60;
gridView1.Columns[6].Caption = "主卡卡号";
gridView1.Columns[6].Width = 100;
gridView1.Columns[7].Caption = "主卡持卡人";
gridView1.Columns[7].Width = 60;
gridView1.Columns[8].Caption = "通行时间";
gridView1.Columns[8].Width = 100;
gridView1.Columns[9].Caption = "车牌号码";
gridView1.Columns[9].Width = 60;
gridView1.Columns[10].Visible = false;//图象GUID
gridView1.Columns[11].Caption = "异常描述";
gridView1.Columns[11].Width = 100;
gridView1.Columns[12].Caption = "处理结果";
gridView1.Columns[12].Width = 100;
gridView1.Columns[13].Visible = false;//ImageID
//可以排序
gridView1.OptionsCustomization.AllowSort=true;
}
其中有一列显示时间类型
gridView1.Columns[3].Caption = "操作时间";
gridView1.Columns[3].Width = 200;
gridView1.Columns[3].UnboundType = DevExpress.Data.UnboundColumnType.DateTime;
gridView1.Columns[3].DisplayFormat.FormatString = "F";
gridView1.Columns[3].DisplayFormat.FormatType = FormatType.DateTime;
