1)DataLayout可以自动根据绑定的数据生成需要的label和Text. 不过它需要设计时支持.
我研究了下如何动态绑定, 上代码:
x = New InterviewersService
Dim t As Interviewers = x.GetByIntid("100002") Dim y As New BindingList(Of Interviewers) y.Add(t) Me.DataLayoutControl1.DataSource = y Me.DataLayoutControl1.RetrieveFields()2)那么在修改后如何写回去呢?继续上:
Dim a As CurrencyManager = CType(Me.DataLayoutControl1.BindingContext(Me.DataLayoutControl1.DataSource, Me.DataLayoutControl1.DataMember), CurrencyManager) Dim b As Interviewers= CType(a.Current, Interviewers) x.Save(b)3) 如何修改自动生成的Datalayout呢?
'设置生成的label的文本Me.DataLayoutControl1.Items(2).Text = "访问员编号"
For Each baseItem As BaseLayoutItem In DataLayoutControl1.Items Dim item As LayoutControlItem = TryCast(baseItem, LayoutControlItem) If Not item Is Nothing Then If item.Control.DataBindings(0).BindingMemberInfo.BindingField = "EntityId" Or item.Control.DataBindings(0).BindingMemberInfo.BindingField = "Tag" Or item.Control.DataBindings(0).BindingMemberInfo.BindingField = "Error" Then 'Hide this item DataLayoutControl1.AddToHiddenItems(item) End If End If Next baseItem太纠结了, 省的时间估计还没有用的多...算了还是手写拖控件吧, 至少更灵活
