隐藏iframe实现无刷新的效果

有时候没办法要用到的微软的一些服务器端的控件，如gridview，这时候如果你想获取这个控件里面的值的话，又不想刷新整个页面，这时候隐藏的iframe就可以用上场了。

 

实现的原理很简单，就是在form里面将target="iframename" 赋值与隐藏的iframe的name相等，就可以调用服务器端控件直接在asp.cs页面里面的方法了，但是刷新的是隐藏的iframe，所以你看不到页面的刷新。

 

简单代码演示：

<iframe name="iframename" style="display:none;"></iframe>

<form runat="server" method="post" enctype="multipart/form-data"   target="iframename" onsubmit="return save(this)">

<table >
 <tr>
 <asp:GridView ID="GridView1" runat="server" AllowSorting="True" AutoGenerateColumns="False" OnRowDataBound="GridView1_RowDataBound"  DataKeyNames="Fid,FMask"  >
                                    <Columns>
                                    <asp:BoundField DataField="Group" HeaderText="模块" ReadOnly="True" >
                                        <ItemStyle HorizontalAlign="Left" Width="200px" />
                                    </asp:BoundField>
                                    <asp:BoundField DataField="FName" HeaderText="功能列表" ReadOnly="True" >
                                        <ItemStyle HorizontalAlign="Left" />
                                    </asp:BoundField>
                                    <asp:BoundField DataField="FObjectDetailDesc" HeaderText="操作" ReadOnly="True" >
                                        <ItemStyle HorizontalAlign="Left" Width="150px" />
                                    </asp:BoundField>
                                    <asp:TemplateField meta:resourcekey="TemplateFieldResource1">
                                        <HeaderTemplate>
                                            <asp:Label ID="lbAuthorize" runat="server" Text="授权" ></asp:Label>
                                            <asp:CheckBox ID="chkSelectAll" runat="server" onclick="selectAll(this)"  />
                                        </HeaderTemplate>
                                        <ItemTemplate>
                                            <asp:CheckBox ID="chkSelect" runat="server" Text=" " />
                                        </ItemTemplate>
                                        <ItemStyle Width="120px" />
                                        <HeaderStyle Width="120px" />
                                    </asp:TemplateField>
                                </Columns>
                                <RowStyle HorizontalAlign="Left" />
                            </asp:GridView>

</tr>

<tr> <asp:Button ID="btnSave" runat="server"     OnClick="lbnSave_Click"  /></tr>
  </table>
</form>

 

 

asp.cs代码

protected void lbnSave_Click(object sender, EventArgs e)
    {

                    foreach (GridViewRow row in GridView1.Rows)
                    {
                        cb = (CheckBox)row.FindControl("chkSelect");
                        //在这里就可以尽情地玩转那该死的gridview控件啦，但是在页面上却看不到刷新的效果的

                       //

              
          

                     }
 
    }

 

 

这种方法同样适用于嵌入不完整的页面的局部刷新的适用
