Question

我正在尝试绑定一个IsEnabled属性来检查是否可以编辑GridColumn。现在Binding I确实喜欢这个

<telerik:GridViewDataColumn Header="Quantity Shipped" UniqueName="QuantityShipped" DataMemberBinding="{Binding QuantityShipped}" IsEnabled="{Binding TblLstStatus.StatusValue, Converter={StaticResource StatusValToBool},ConverterParameter='20;200'}" Width="Auto" CellStyle="{StaticResource CellStyleNormal}">

现在我收到了这个Binding错误

System.Windows.Data Error: 40 : BindingExpression path error: 'TblLstStatus' property not found on 'object' ''ViewModelSalesOrder' (HashCode=1285414)'. BindingExpression:Path=TblLstStatus.StatusValue; DataItem='ViewModelSalesOrder' (HashCode=1285414); target element is 'GridViewDataColumn' (HashCode=55181770); target property is 'IsEnabled' (type 'Boolean')

由于某种原因，编译器正在为对象TblLstStatus搜索错误的位置，我不知道为什么..

网格声明

<telerik:RadGridView x:Name="dataGridDetail" d:LayoutOverrides="Height" ItemsSource={Binding SelectedItem.TblDatODSales, ElementName=dataGrid}" Background="{x:Null}" Grid.Row="2" Grid.ColumnSpan="2" 
RowHeight="20" CanUserDeleteRows="False" CanUserInsertRows="False" AutoGenerateColumns="False" ShowGroupPanel="False" IsFilteringAllowed="false" SelectionMode="Single" SelectionChanged="dataGrid_SelectionChanged"
EditTriggers="Default,CellClick">

父网格

<telerik:RadGridView x:Name="dataGrid" ItemsSource="{Binding Orders}" d:LayoutOverrides="Height" Background="{x:Null}" Grid.ColumnSpan="2" 
RowHeight="20" CanUserDeleteRows="False" CanUserInsertRows="False" AutoGenerateColumns="False" ShowGroupPanel="True" IsFilteringAllowed="true" SelectionMode="Single" 
MouseDoubleClick="dataGrid_MouseDoubleClick" EditTriggers="Default,CellClick">

数据操作（DevForce）

query = query.Include("TblLstStatus")
                         .Include("TblLstStaff_Req")
                         .Include("TblLstStaff_Resp")
                         .Include("TblLstOrganisation_Req")
                         .Include("TblDatODSales.TblLstART")
                         .Include("TblDatODSales.TblLstStatus").OrderByDescending(c => c.CreationDate);

            statusQuery = statusQuery.Include("TblLstStatusType");

            _dataService.GetManager().ExecuteQueryAsync(query, argsv =>
            {
                if (argsv.Error == null && argsv.Results != null)
                {
                    this.Orders = new ObservableCollection<TblDatOrderSales>(argsv.Results);
                }
            }, null);

我尝试过的事情

将整个对象路径添加到绑定
更改为ReadOnly（同一错误）

在错误的地方绑定搜索
