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>
                                    <asp:LinkButton ID="SelectedPhysician" runat="server" Text="Select" CommandName="SelectAffiliation" />
                                </ItemTemplate>
                            </asp:TemplateField>
                            <asp:BoundField HeaderText="Physician ID" DataField="AMDM_Phys_ID" HeaderStyle-HorizontalAlign="Left"
                                ItemStyle-HorizontalAlign="Left" HeaderStyle-Width="70px" ItemStyle-Width="70px" />
                        </Columns>
                    </asp:GridView>

以下是上面网格的行绑定函数

Private Sub PhysicianGrid_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles PhysicianGrid.RowDataBound


    If e.Row.RowType = DataControlRowType.DataRow Then
        Dim selectLink As LinkButton = DirectCast(e.Row.FindControl("SelectedPhysician"), LinkButton)
        Dim physId As String = e.Row.Cells(1).Text
        If OperationType.Value.Equals("ADD ALLOCATION") Then
            selectLink.OnClientClick() = String.Format("DisplayUpdateAllocationDivFromSearch('{0}');", physId)
        Else
            'selectLink.OnClientClick() = String.Format("DisplayUpdateAllocationDivFromSearchNewPhy('{0}');", physId)
            selectLink.CommandArgument = physId
        End If
        selectLink.CommandArgument = physId
    End If
End Sub

当我点击选择链接时,应用程序获得回发并点击page_load函数但是点击事件处理程序

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, "", "", "", "")
            GridSelectedShipToAllocations.DataSource = dt
            GridSelectedShipToAllocations.DataBind()
            GridSelectedShipToAllocations.Style("display") = "block"
            'DivAddAllocationChange.Style("display") = "none"
            LabelTotal.Style("display") = "block"
            ScriptManager.RegisterStartupScript(Me.PhysicianGrid, GetType(Page), "hideSearchPhysDiv", "DisplayUpdateAllocationDivFromSearchNewPhy('" + selectedPhys.ToString + "');", True)

        End If

    End If

End Sub

如何让它命中行命令功能

P.S。我需要在网格中使用EnableViewState ="False"属性我无法删除此属性。这个问题有解决办法吗?

这是我在最近的一个项目中实现它的方式,可能它可以帮助您找到问题。命令参数已在ASPX中指定,而不是RowDataBound事件 作为一种解决方法,您可以只注释掉RowDataBound事件中的代码并在ASPX中设置CommandArgument并检查会发生什么。
另外,我认为您可以尝试Request.Form("__EVENTTARGET").Contains("SelectedPhysician")

而不是e.CommandName.Equals("SelectedPhysician")

<强> ASPX:

<asp:GridView ID="gvStudents" runat="server" AutoGenerateColumns="false">
  <Columns>
    ...
    <asp:TemplateField>
      <ItemTemplate>
        <asp:LinkButton ID="BtnUnlock" runat="server" Text="Unlock" CausesValidation="True" CommandName="UnlockProfile" CommandArgument='<%# Eval("User_ID") %>' />
      </ItemTemplate>
    </asp:TemplateField>
    ...
  </Columns>
</asp:GridView>

<强>代码隐藏:

Private Sub gvStudents_RowCommand(sender As Object, e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles gvStudents.RowCommand
    If e.CommandName.Equals("UnlockProfile") Then
        Dim lnUser_ID As Integer = Convert.ToInt32(e.CommandArgument)
        ...
    ElseIf e.CommandName.Equals("LockProfile") Then
        ...
    End If
End Sub
