点击GridView弹出模态窗口，但关闭时刷新不到父窗口

Question

父窗口:
弹出模态窗口的javascript
function ComplementMaintenanceInfoWindows(InfoID)
{
    debugger;
    sRet4=window.showModalDialog("ComplementMaintenanceInfoUI.aspx?InfoID="+InfoID+"&time="+Date(),"补单","scrollbars=no;resizable=yes;help=no;status=no;dialogHeight=450px;dialogwidth=580px;center=yes"); 
    if(sRet4=="refresh") {
        window.location.href =window.location.href ;
    }
}
其中点击GridView的ButtonField"补单"，将会弹出模态窗口
<asp:GridView ID="GridView1" runat="server" AllowPaging="True" AutoGenerateColumns="False"
    BackColor="White" BorderColor="Black" PageSize="15" DataKeyNames ="InfoID"
    onpageindexchanging="GridView1_PageIndexChanging"
    onrowdatabound="GridView1_RowDataBound" >
    <Columns>   
        <asp:BoundField DataField="WorkNo" HeaderText="单号"> </asp:BoundField>
        <asp:BoundField DataField="Status" HeaderText="工单状态"> </asp:BoundField>
        <asp:BoundField DataField="UserName" HeaderText="维修工程师"> </asp:BoundField>
        <asp:BoundField DataField="CUnits" HeaderText="客户单位"> </asp:BoundField>
        <asp:ButtonField  CommandName="Print" Text="补单" HeaderText="补单"> </asp:ButtonField>
    </Columns>
    <PagerStyle HorizontalAlign="Center" />
    <AlternatingRowStyle BackColor="#CCCCCC" />
</asp:GridView>

//后台cs绑定
if (e.Row.RowType.Equals(DataControlRowType.DataRow))
{
    LinkButton btDatail = (LinkButton)e.Row.Cells[4].Controls[0];
    btDatail.Attributes.Add("onclick", "ComplementMaintenanceInfoWindows(" + this.GridView1.DataKeys[e.Row.RowIndex].Values["InfoID"].ToString() + ")");
}

模态窗口
Response.Write(" <script>alert('保存成功！');window.returnValue='refresh';window.close(); </script>");


问题是：在关闭模态窗口的时候刷新不到GridView，但是这种写法对页面上的按钮就没有问题。我试过这种
Button btDatail = (Button)e.Row.Cells[4].Controls[0];但是，会提示无法转换。

Answer 1

你好！

你的第 5 列不是 LinkButton，把第 5 列转成模板列后，再向模板列中添加一个 LinkButton

Answer 2

你好 Linkbutton 会导致自动回发的  而在模式窗体关闭之前页面已经刷新了
