GridControl

===============1、禁止编辑========================================

1.1 这个是整个表格都不可编辑

gridView1.OptionsBehavior.Editable = false; 

1.2 这个是某列不可编辑，gridColumn1你不想让编辑的列可以是gridColumn1，gridColumn2，gridColumn3 自己根据情况设置就好了
gridColumn1.OptionsColumn.AllowEdit = false; 

1.3 这是某行某列禁止编辑 

private void gvSAPPlan_ShowingEditor(object sender, CancelEventArgs e) 
{
if (paperPA1052DtoBindingSource.Current is PaperPA1052Dto current && current != null)
{
if (current.CZspzt == PaperPlanConst.Spzt_Y) e.Cancel = true;
}
}

==============2、编辑框及转义==========================================

2.1  自定义控件

collnr1.ColumnEdit = columnEdit;

var widget = new SearchPopupWidget(keywords =>
{
var list = xxxx.Proxy.Query(Plant, keywords)
.Select(x => new ValueDisplayItem
{
DisplayName = x.txt,
Value = x.lnr,
Tag = x
}).ToList();
return list;
});

var columnEdit = widget.CreateRepositoryItemButtonEdit(x =>
{
var row = this.bscXXX.Current as xxxDto;
row.lnr = x.Value;
row.lnrName = x.DisplayName;
this.gvXxxx.BestFitColumns();
});

2.2  自定义转义内容  
CustomColumnDisplayText 事件e.Column.Name
this.colXxxx.ColumnEdit = WidgetsHelper.GetRepositoryItemImageComboBox(new object[] { "F", "未发", "Y", "已发" });

2.2  同步行选择

同步行选择状态到checkbox选择列(selected_column)
ViewControl.Config(gcXXX).AllowSyncRowStateToCheckboxSelection = true;

底部汇总

GridView->FooterPanel

                OptionsView:ShowFooter=true

Columns->SummaryItem->SummaryType = Sum
数：{0} Count
长 SUM={0:0.##}
重量 SUM={0:0.##}
剩余重量 SUM={0:0.##}

gdvNew.Focus(); //GridControl 控件获取焦点
gdvNew.FocusedRowHandle = _smtReport.Count - 1; //设置焦点行
gdvNew.FocusedColumn = gdvNew.Columns[0];//设置焦点单元格

获取选中行某列的值

int selectedHandle;
selectedHandle = this.gridView1.GetSelectedRows()[0];
MessageBox.Show(this.gridView1.GetRowCellValue(selectedHandle, "RoadName").ToString());
获得选中行的单元格的值（注：“RoadName”代表属性字段）
