Telerik Hierarchical RadGrid NeedDatasource：如何引用ParentID？

发布于 2024-12-14 19:16:47 字数 439 浏览 2 评论 0原文

我有一个 RadGrid，在 RadGrid1.MasterTableView.NestedViewTemplate 内有另一个 RadGrid。外部 RadGrid 为 RadGrid1，内部 RadGrid 为 RadGrid2。两个 RadGrid 都是通过代码隐藏创建的。我定义了一个关系，如下所示：

RadGrid1.MasterTableView.NestedViewSettings.ParentTableRelation.Add(New Telerik.Web.UI.GridRelationFields() With {.DetailKeyField = "ID", .MasterKeyField = "ID"})

我的问题是：

我有一个内部 RadGrid 的 NeedDatasource 事件，我想按父行 ID 的 ID 进行过滤。我怎样才能做到这一点？

原文

I have a RadGrid and inside the RadGrid1.MasterTableView.NestedViewTemplate I have another RadGrid. The outer RadGrid is RadGrid1, the inner RadGrid is RadGrid2. Both the RadGrids were created from code behind. I've defined a relation, like this:

RadGrid1.MasterTableView.NestedViewSettings.ParentTableRelation.Add(New Telerik.Web.UI.GridRelationFields() With {.DetailKeyField = "ID", .MasterKeyField = "ID"})

My question is:

I have a NeedDatasource event for the inner RadGrid and I would like to filter by the ID of the parent row's ID. How can I do that?

问题解决了。我使用以下委托为 RadGrid2.NeedDatasource 添加了一个处理程序：

    Public Sub RadGrid2_NeedDatasource(ByVal source As Object, ByVal e As GridNeedDataSourceEventArgs)
        Dim innerGrid As RadGrid = CType(source, RadGrid)
        Dim nestedItem As GridNestedViewItem = CType(innerGrid.NamingContainer, GridNestedViewItem)
(nesteditem.ParentItem)).GetDataKeyValue("ID")); 
        Dim ShiftID = CType(nestedItem.ParentItem, GridDataItem).GetDataKeyValue("ID")
        '...
    End Sub

Problem solved. I've added a handler for the RadGrid2.NeedDatasource with the following delegate:

    Public Sub RadGrid2_NeedDatasource(ByVal source As Object, ByVal e As GridNeedDataSourceEventArgs)
        Dim innerGrid As RadGrid = CType(source, RadGrid)
        Dim nestedItem As GridNestedViewItem = CType(innerGrid.NamingContainer, GridNestedViewItem)
(nesteditem.ParentItem)).GetDataKeyValue("ID")); 
        Dim ShiftID = CType(nestedItem.ParentItem, GridDataItem).GetDataKeyValue("ID")
        '...
    End Sub
