问一下哪位大牛可以解答一下啊,急!!!
gridControl设置为BandedGridView后数据绑定不上去.
代码:
public void InitGridView()
{
var g = gridControl1;
var view = new BandedGridView();
g.MainView = view;
g.Dock = DockStyle.Fill;
view.BeginUpdate();
view.BeginDataUpdate();
view.Bands.Clear();
view.OptionsView.ShowColumnHeaders = false;
view.OptionsView.ShowGroupPanel = false;

records = RecordList();

foreach (var item in records)
{
GridBand bandCategory = view.Bands.AddBand(item.Category);
bandCategory.AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;
GridBand bandJingdong = bandCategory.Children.AddBand(“京东”);
GridBand bandTianmao = bandCategory.Children.AddBand(“天猫”);
GridBand bandGuanwang = bandCategory.Children.AddBand(“官网”);
var aa1 = new BandedGridColumn();
aa1.FieldName = “Jingdong”;
aa1.Visible = true;
bandJingdong.Columns.Add(aa1);
var aa2 = new BandedGridColumn();
aa2.FieldName = “Tianmao”;
aa2.Visible = true;
bandTianmao.Columns.Add(aa2);
var aa3 = new BandedGridColumn();
aa3.FieldName = “Offical”;
aa3.Visible = true;
bandGuanwang.Columns.Add(aa3);
}
gridControl1.DataSource = records ;
gridControl1.MainView.PopulateColumns();
view.EndDataUpdate();
view.EndUpdate();

}
数据源:
public List<SalesRecord> RecordList()
{
SalesRecord sa = new SalesRecord
{
Category = “服装”,
Paydate = “2016-08-11”,
Offical = “40”,
Jingdong = “40”,
Tianmao = “40”,
Sumquantity = “40”
};
records.Add(sa);
SalesRecord sa1 = new SalesRecord
{
Category = “女鞋”,
Paydate = “2016-08-11”,
Offical = “40”,
Jingdong = “40”,
Tianmao = “40”,
Sumquantity = “40”,
};
records.Add(sa1);
SalesRecord sa2 = new SalesRecord
{
Category = “童装/童鞋/亲子装”,
Paydate = “2016-08-11”,
Offical = “40”,
Jingdong = “40”,
Tianmao = “40”,
Sumquantity = “40”,
};
records.Add(sa2);
return records;
}
运行结果:
