我将 jqGrid 用作带有 ASP.NET MVC4 的 TreeGrid,但有一个问题:
我的模型:
OrdersGrid = new JQGrid
{
Columns = new List<JQGridColumn>()
{
new JQGridColumn
{
DataField = "MeasureId",
// always set PrimaryKey for Add,Edit,Delete operations
// if not set, the first column will be assumed as primary key
PrimaryKey = true,
Visible = false,
Sortable = false
},
new JQGridColumn
{
DataField = "Name",
Width = 100,
Sortable = true
},
new JQGridColumn
{
DataField = "Symbol",
Width = 100
},
},
Width = Unit.Pixel(640),
Height = Unit.Percentage(100),
TreeGridSettings = new TreeGridSettings
{
Enabled = true
},
SortSettings = new SortSettings
{
AutoSortByPrimaryKey = false,
InitialSortColumn = "Name",
InitialSortDirection = SortDirection.Asc
}
};
我的控制器:
public JsonResult DataRequested()
{
// Get both the grid Model and the data Model
// The data model in our case is an autogenerated linq2sql database based on Northwind.
var gridModel = new NavigatorModel();
...
var hierarchyRows = from measure in measures
select new
{
MeasureId = measure.MeasureId,
Name = measure.Name,
Symbol = measure.Symbol,
//ParentID = measure.ParentMeasureId != null ? measure.ParentMeasureId.ToString() : "",
tree_loaded = true,
tree_parent = measure.ParentMeasureId,
tree_level =LoadAllRowsExpanded_GetRowLevel(measure.ParentMeasureId, measures),
tree_leaf = LoadAllRowsExpanded_IsLeafRow(measure.MeasureId, measures),
tree_expanded = true
};
//var dataModel = new
// return the result of the DataBind method, passing the datasource as a parameter
// jqGrid for ASP.NET MVC automatically takes care of paging, sorting, filtering/searching, etc
return gridModel.OrdersGrid.DataBind(hierarchyRows.AsQueryable());
}
如上你可以看到我将 AutoSortByPrimaryKey 设置为 false,但是当页面加载时,网格看起来像这样:
当我单击其中一列(名称或符号)进行排序时,一切都变得很好 - 错误显示的 Measure 在它的父项下。我也尝试使用事件在“gridInitialize”之后排序,但也没有成功。有任何想法吗?
