Asp.net 复选框。选中总是在中继器中返回false

我对Repeater中的复选框总是返回假值有问题。我读过很多关于这方面的问题，总是指给我绑定数据时使用

而不是Page.IsPostBack

，我已经完成了我发现的所有示例问题，但仍然没有解决我的问题

下面是如何绑定复选框：

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    Try
        If Not Page.IsPostBack Then
            Call Load_menu()
        End If
    Catch ex As Exception
        Response.Write("Page_Load Exception :<br>" & ex.ToString)
    End Try
End Sub

Private Sub Load_menu()
    Try
        sqlstring = "SELECT a.menuID, a.name, b.[status] " & _
                    "FROM masterMenu a LEFT JOIN rolesDetail b ON b.menuID=a.menuID " & _
                    "WHERE a.[status] = 1 and b.RoleID = '" & roleID & "' " & _
                    "ORDER BY a.menuID "
        DS = SQLExecuteQuery(sqlstring)
        DT = DS.Tables(0)
        rptMenu.DataSource = DT
        rptMenu.DataBind()
    Catch ex As Exception
        Response.Write("Load_Menu Exception :<br>" & ex.ToString)
    End Try
End Sub

Private Sub rptMenu_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles rptMenu.ItemDataBound
    Try
        If e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem Then
            Dim lblID As Label = e.Item.FindControl("LblID")
            Dim lblName As Label = e.Item.FindControl("LblName")
            Dim cblChild As CheckBox = e.Item.FindControl("cblChild")
            Dim dr As DataRowView = e.Item.DataItem

            lblID.Text = dr.Item("menuID").ToString
            lblName.Text = dr.Item("name").ToString

            If dr.Item("status").ToString = "1" Then
                cblChild.ID = dr.Item("menuID").ToString
                cblChild.Checked = True
            Else
                cblChild.ID = dr.Item("menuID").ToString
                cblChild.Checked = False
            End If
        End If
    Catch ex As Exception
        Throw New Exception("<b>Error RptMenu Data bound :</b>" & ex.ToString)
    End Try
End Sub

我在SQL Server中使用探查器跟踪它，它总是返回

0

值，这意味着

cblChild。选中的
总是返回False

我不知道我错过了什么。
尝试使用
HtmlInputCheckBox
控件，而不是
CheckBox

换行

Dim cblChild As CheckBox = item.FindControl("cblChild")

到

这还需要将html复选框控件与
runat=“server”
一起使用：

Protected Sub btSimpan_Click(sender As Object, e As EventArgs) Handles btSimpan.Click
    Try
        sqlstring = ""
        For i As Integer = 0 To rptMenu.Items.Count - 1
            Dim item As RepeaterItem = rptMenu.Items(i)
            Dim lblID As Label = item.FindControl("LblID")
            Dim cblChild As CheckBox = item.FindControl("cblChild")
            Dim status As String = "0"

            If cblChild.Checked Then
                status = "1"
            End If

            sqlstring = sqlstring & " UPDATE rolesDetail SET [status] = " & status & " " & _
                        " WHERE roleID = '" & roleID & "' AND menuID = '" & lblID.Text.ToString.Replace("'", "''") & "'; "
        Next

        If SQLExecuteNonQuery(sqlstring) > 0 Then
            Response.Redirect("roles.aspx")
        End If
    Catch ex As Exception
        Response.Write("Error btSimpan_Click <BR> " & ex.ToString)
    End Try
End Sub

Dim cblChild As CheckBox = item.FindControl("cblChild")

Dim cblChild As HtmlInputCheckBox = DirectCast(item.FindControl("cblChild"), HtmlInputCheckBox)

<input type="checkbox" runat="server" id='cblChild'/>

cblChild.ID = dr.Item("menuID").ToString
