为什么点击childgridview的编辑按钮，childgridview隐藏？

Question

这是我为嵌套gridview所做的：

我用来维护这个show hide的jQuery是：

<script type="text/javascript">
    // Method for managing opening of gridview on + image and - image

    $("[src*=plus]").live("click", function() {
        $(this).closest("tr").after("<tr><td></td><td colspan = '999'>" + $(this).next().html() + "</td></tr>")
        $(this).attr("src", "../Image/minus.gif");
    });

    $("[src*=minus]").live("click", function() {

        $(this).attr("src", "../Image/plus.gif");
        $(this).closest("tr").next().remove();

    });
</script>

        </asp:TemplateField>


        <asp:CommandField ShowSelectButton="True" SelectText="Select" />
        <asp:CommandField DeleteText="Reject" ShowDeleteButton="True" />
        <asp:CommandField ShowEditButton="true" EditText="Edit" />
    </Columns>
    <FooterStyle BackColor="#1C5E55" Font-Bold="True" ForeColor="White" />

    <EditRowStyle BackColor="#7C6F57" />
    <AlternatingRowStyle BackColor="White" />
</asp:GridView>

在服务器端，这就是我正在做的事情：

 protected void GridView3_RowEditing(object sender, GridViewEditEventArgs e)
    {
        DataSet ds = new DataSet();
        tBL objBL = new tBL();
        GridViewRow editedRow = GridView1.Rows[e.NewEditIndex];
        //now search row for your control...
        GridView GridView3 = (GridView)editedRow.FindControl("GridView3");

        GridView3.EditIndex = e.NewEditIndex;

        objtxtToTableBL.ViewBL(dt);
        GridView3.DataSource = dt;
        GridView3.DataBind();
    }

    protected void GridView3_RowCancelling(object sender, GridViewCancelEditEventArgs e)
    {
        GridView1.EditIndex = -1;
    }

    protected void GridView3_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
    }

我绑定gridview rowdatabound GridView1上的嵌套{{1}}，这样可以正常工作。

所有这一切的问题是当我点击innergridview（child）的编辑按钮时，它会隐藏为页面回发。

我应该怎么做，当我点击其编辑按钮时，子网格视图保持打开状态，只有当我点击减号按钮时它才会隐藏。请帮助它已经用了3天了。
