CheckBoxList數據綁定錯誤

Question

我一直有一些麻煩加載CheckBoxList數據。我一直在DisplayMember和ValueMember上出現一些錯誤。

這是我的鱈魚：。

Protected Sub LoadCBMembers(ByVal objDeptGUID As String) 
    Try 
     Dim myCBTable As New DataTable() 
     With myCBTable.Columns 
      .Add("DisplayName", GetType(String)) 
      .Add("TextValue", GetType(String)) '<<<< change the type of this column to what you actually need instead of integer. 
     End With 
     Dim lqMembers As New lqFireFighterConnectDataContext 
     Dim GetMembers = From r In lqMembers.tbUsers 
         Where r.DeptGUID = objDeptGUID And r.TextFLag = True 
         Select r 
     If GetMembers.Count = 0 Then 
      Exit Sub 
     End If 
     For Each foundMember In GetMembers 
      myCBTable.Rows.Add(foundMember.FirstName & " " & foundMember.LastName, foundMember.CellPhone & "@" & foundMember.PhoneCarriers) 
      ' cbMembers.Items.Add(foundMember.FirstName & " " & foundMember.LastName) 
     Next 
     With cbMembers 
      .DataSource = myCBTable 
      .DisplayMember = "DisplayName" 
      .ValueMember = "TextValue" 
     End With 

    Catch ex As Exception 

    End Try 
End Sub 

Answer 1

試試這個：

With cbMembers 
     .DataSource = myCBTable 
     .DisplayMember = "DisplayName" 
     .ValueMember = "TextValue" 
     .DataBind() 
    End With 

按照documentation，這種方法必須顯式調用。並非所有的控件都需要明確地調用DataBind()（對於很多情況它會隱式調用），但CheckBoxList是個例外。
