在 ASP.NET 4.0 GridView 中，是否可以同时在编辑模式下拥有多行？

我在属性中使用编辑模式控制行：

Private Property Editing As List(Of Integer)
   Get
       If ViewState("Editing") Is Nothing Then ViewState("Editing") = New List(Of Integer)
       Return CType(ViewState("Editing"), List(Of Integer))
   End Get
   Set(value As List(Of Integer))
       ViewState("Editing") = value
   End Set
End Property

当用户点击编辑按钮时填充它：

Protected Sub GridView1_RowCommand(sender As Object, e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles GridView1.RowCommand
    If e.CommandName = "Edit" Then
        Dim row = CType(CType(e.CommandSource, LinkButton).NamingContainer, GridViewRow)
        Editing.Add(row.RowIndex)
    End If
End Sub

并在 RowDataBound 事件中手动更改 RowState 属性：

Protected Sub GridView1_RowDataBound(sender As Object, e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
    If e.Row.RowType = DataControlRowType.DataRow Then
        If Editing.Contains(e.Row.RowIndex) Then
            Then e.Row.RowState = DataControlRowState.Edit
        End If
    End If
End Sub

但它不起作用，行正在以正常状态呈现......任何想法？

MultipleEditGridView.vb：

Namespace ClubeCheckIn.UI

        Public Class MultipleEditGridView
            Inherits GridView

            Protected Property IsRowInEditMode(rowIndex As Int32) As Boolean
                Get
                    If ViewState("GridRowEditIndices") Is Nothing Then
                        Return False
                    Else
                        Dim indices = DirectCast(ViewState("GridRowEditIndices"), List(Of Int32))
                        Return indices.Contains(rowIndex)
                    End If
                End Get
                Set(value As Boolean)
                    If ViewState("GridRowEditIndices") Is Nothing Then
                        ViewState("GridRowEditIndices") = New List(Of Int32)
                    End If
                    Dim indices = DirectCast(ViewState("GridRowEditIndices"), List(Of Int32))
                    indices.Remove(rowIndex)
                    indices.Add(rowIndex)
                End Set
            End Property

        End Class

    End Namespace

网络配置：

<controls>
    <add tagPrefix="clube" namespace="ClubeCheckIn.UI" />
</controls>

ASPX：

<clube:MultipleEditGridView ID="GridView1" runat="server">
    <Columns>
        <asp:TemplateField>
            <ItemTemplate>
                <asp:TextBox ID="txtEdit" runat="server" Visible="<%# IsRowInEditMode(Container.DataItemIndex) %>" />
            </ItemTemplate>
    </Columns>
</clube:MultipleEditGridView>

错误：

错误：BC30451：未声明“IsRowInEditMode”。由于保护级别，它可能无法访问

我很确定GridView在编辑模式下不支持多行。

作为一种解决方法，您可以将ItemTemplate用于两种状态（fe aLabel和 a TextBox）。然后，您可以使用EditMode带有RowIndexas 参数的属性。您可以将行以编辑模式存储在ViewState.

（未测试）

Protected Property IsRowInEditMode(rowIndex As Int32) As Boolean
    Get
        If ViewState("GridRowEditIndices") Is Nothing Then
            Return False
        Else
            Dim indices = DirectCast(ViewState("GridRowEditIndices"), List(Of Int32))
            Return indices.Contains(rowIndex)
        End If
    End Get
    Set(value As Boolean)
        If ViewState("GridRowEditIndices") Is Nothing Then
            ViewState("GridRowEditIndices") = New List(Of Int32)
        End If
        Dim indices = DirectCast(ViewState("GridRowEditIndices"), List(Of Int32))
        indices.Remove(rowIndex)
        indices.Add(rowIndex)
    End Set
End Property

您可以直接从标记中调用它， fe 用于编辑控件：

Visible='<%# IsRowInEditMode(Container.DataItemIndex) %>

你可以用这个对面糊有用...

   Get
        If ViewState("GridRowEditIndices") Is Nothing Then
            Return False
        Else
            Dim indices = DirectCast(ViewState("GridRowEditIndices"), List(Of Int32))
            Return indices.Contains(rowIndex)
        End If
    End Get
    Set(value As Boolean)
        If ViewState("GridRowEditIndices") Is Nothing Then
            ViewState("GridRowEditIndices") = New List(Of Int32)
        End If
        Dim indices = DirectCast(ViewState("GridRowEditIndices"), List(Of Int32))
        indices.Remove(rowIndex)
        indices.Add(rowIndex)
    End Set
End Property
