你可以修改报表的构造函数，代码如下：

public XtraReport1() {
InitializeComponent();
//
// TODO: Add constructor logic here
//

this.categoriesTableAdapter1.Fill(this.dataSet11.Categories);

for (int i = 0; i < this.dataSet11.Categories.Count; i++) {
SkippedDetailBands.Add(this.dataSet11.Categories[i].CategoryID, true);
}
}
