我有一个绑定到bindingSource的xtraGrid控件（v12.1），这最后一个数据是从LINQ到实体查询（EF4.3.1）获取的，最终用户可以对gridView进行过滤和排序，我有一个Stimulsoft报告当用户单击PrintListButton时，该视图显示gridView的内容，如何将xtragrid过滤和排序的数据源添加到报表中？ 谢谢。

I have an xtraGrid control (v12.1) binded to a bindingSource, this last gets its data from a LINQ to entities query (EF4.3.1), the end user can filter and sort the gridView, I have a Stimulsoft report that shows the content of the gridView when the user clicks on a PrintListButton, how to get the xtragrid filtered and sorted datasource, in order to attach it to the report? Thanks.

推荐答案

var data = GetDataView(xtraGridControl1); report.RegData("List", data.ToTable()); public DataView GetDataView(GridControl gc) { DataView dv = null; if (gc.FocusedView != null && gc.FocusedView.DataSource != null) { var view = (ColumnView)gc.FocusedView; var currentList = listBindingSource.List.CopyToDataTable().DefaultView; //(DataView) var filterExpression = GetFilterExpression(view); var sortExpression = GetSortExpression(view); var currentFilter = currentList.RowFilter; //create a new data view dv = new DataView(currentList.Table) {Sort = sortExpression}; if (filterExpression != String.Empty) { if (currentFilter != String.Empty) { currentFilter += " AND "; } currentFilter += filterExpression; } dv.RowFilter = currentFilter; } return dv; } public string GetFilterExpression(ColumnView view) { var expression = String.Empty; if (view.ActiveFilter != null && view.ActiveFilterEnabled && view.ActiveFilter.Expression != String.Empty) { expression = view.ActiveFilter.Expression; } return expression; } public string GetSortExpression(ColumnView view) { var expression = String.Empty; foreach (GridColumnSortInfo info in view.SortInfo) { expression += string.Format("[{0}]", info.Column.FieldName); if (info.SortOrder == DevExpress.Data.ColumnSortOrder.Descending) expression += " DESC"; else expression += " ASC"; expression += ", "; } return expression.TrimEnd(',', ' '); }
