您好，我正在使用以下代码在aspx上显示网格

 <asp:GridView Caption="Search Results" ID="PhysicianGrid"
                        runat="server" EnableSortingAndPagingCallbacks="false" PageSize="5" Style="width: 100%"
                        PagerSettings-Visible="false" AutoGenerateColumns="false" CssClass="grid" RowStyle-CssClass="gridDataRow"
                        HeaderStyle-CssClass="headerRow" EnableViewState ="False">
                        <Columns>
                            <asp:TemplateField HeaderText="Select">
                                <HeaderStyle Width="70px" HorizontalAlign="Center" />
                                <ItemStyle HorizontalAlign="Center" />
                                <ItemTemplate>

                        </Columns>
                    </asp:GridView>

当我点击select链接时，应用程序得到回发并点击page_load函数，但点击事件处理程序

Private Sub PhysicianGrid_Command(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles PhysicianGrid.RowCommand
    If _requestView.CRTypeId = Resources.PageResources.CRTYPEAddNewPhysician AndAlso Request.Form("__EVENTTARGET").Contains("SelectedPhysician") AndAlso OperationType.Value.Equals("ADD NEW PHY") Then

        Dim selectedPhys As Integer = CInt(e.CommandArgument)
        Dim tempPhys As PhysicianView = New PhysicianView
        tempPhys.LoadSearchPhysician(Master.Environment, selectedPhys, True)
        Dim dt As ShipToDetailsDataSet.AMU_SHIPTO_ALLOCATION_VDataTable = New ShipToDetailsDataSet.AMU_SHIPTO_ALLOCATION_VDataTable
        If allocationOperation.Value.Equals("UPDATE") Then
            If GridSelectedShipToAllocations.Rows.Count > 0 Then
                For Each row As GridViewRow In GridSelectedShipToAllocations.Rows

                    Dim allocationString As String = DirectCast(row.FindControl("TextBoxNewAllocation"), TextBox).Text
                    SaveGridAllocationChangeForPostback(allocationString)
                    dt.AddAMU_SHIPTO_ALLOCATION_VRow(CInt(_shipToID), CInt(row.Cells(GridSelectedShipToAllocations_columns.colAMDM_PHYS_ID).Text), row.Cells(GridSelectedShipToAllocations_columns.colPhysician_Name).Text, Nothing, CDec(row.Cells(GridSelectedShipToAllocations_columns.colAllocation).Text.Substring(0, row.Cells(GridSelectedShipToAllocations_columns.colAllocation).Text.Length - 1)), CDate("01/01/2007"), Nothing, "", "", "", row.Cells(GridSelectedShipToAllocations_columns.colMajorSpec).Text.Replace("&nbsp;", ""), row.Cells(GridSelectedShipToAllocations_columns.colSecondarySpecialty).Text.Replace("&nbsp;", ""), row.Cells(GridSelectedShipToAllocations_columns.colTertiarySpecialty).Text.Replace("&nbsp;", ""), "", "", "", "")
                Next
            End If
            dt.AddAMU_SHIPTO_ALLOCATION_VRow(CInt(_shipToID), tempPhys.PhysicianID, String.Format("{0}, {1} {2}", tempPhys.LastName, tempPhys.FirstName, tempPhys.MiddleName), Nothing, 0, CDate("01/01/2007"), Nothing, tempPhys.StatusId, tempPhys.FirstName, tempPhys.LastName, tempPhys.MajorSpec, tempPhys.SECONDARY_SPECIALTY_LD, tempPhys.TERTIARY_SPECIALTY_LD, "", "", "", "")

            ScriptManager.RegisterStartupScript(Me.PhysicianGrid, GetType(Page), "hideSearchPhysDiv", "DisplayUpdateAllocationDivFromSearchNewPhy('" + selectedPhys.ToString + "');", True)

我如何让它点击row命令函数

另外，我需要在网格中使用EnableViewState=False属性，我无法删除该属性。这个问题有什么解决方法吗？

这是我在最近的一个项目中实现它的方法，也许它可以帮助您找到问题所在。已在ASPX而不是RowDataBound事件中指定命令参数。作为解决方法，您可以只注释掉RowDataBound事件中的代码，并在ASPX中设置CommandArgument，然后检查发生了什么。此外，我认为您可以尝试e.CommandName.EqualsSelectedMedicine，而不是Request.Form\u EVENTTARGET.containsSelectedMedicine

ASPX：

你是否有任何错误，如果有，那么你也应该在这里提及。您是否尝试过调试模式并检查了CRTypeId的值，Request.Form\uuu EVENTTARGET.containsselectedMedicine和OperationType.Value？不，我没有收到任何错误，只是我编写了几行代码，当用户单击选择链接时需要执行这些代码，但单击选择链接正在执行回发，但它没有点击行命令及其事件处理程序。我不确定，可能是这样的导致问题的代码。只是一个猜测，一旦客户端单击并命令在一起。。。选择link.OnClientClick。
