本文介绍了一种使用JavaScript来实现嵌套Gridview的展开与隐藏功能的方法。通过客户端脚本控制显示状态，并在ASP.NET中实现了外层与内层Gridview的数据绑定。

具体效果如下：

JS代码，用于显示隐藏嵌套的GRIDVIEW：

JS部分代码

/*隐藏嵌套的Gridview*/
function ShowHidden(sid, ev) {
ev = ev || window.event;
var target = ev.target || ev.srcElement;
var oDiv = document.getElementById("div" + sid);
oDiv.style.display = oDiv.style.display == "none" ? "block" : "none";
target.innerHTML = oDiv.style.display == "none" ? "展开列表" : "隐藏列表";
}

Gridview嵌套前台代码：

Gridview嵌套

<asp:GridView ID="gvItem" Width="600px" OnRowDataBound="gvItem_RowCommand" DataKeyNames="ID"
runat="server" AutoGenerateColumns="False">
<Columns>
<asp:BoundField DataField="ID" HeaderStyle-Width="15%" HeaderText="ID">
<HeaderStyle Width="15%" />
</asp:BoundField>
<asp:BoundField DataField="姓名" HeaderStyle-Width="30%" HeaderText="姓名">
<HeaderStyle Width="30%" />
</asp:BoundField>
<asp:TemplateField HeaderStyle-Width="40%">
<ItemTemplate>

<span id="btnShowHidden<%#Eval("ID") %>" style="float: right; color: Red; cursor: pointer;
margin: 0 0 0 0" onclick="ShowHidden('<%#Eval("ID") %>',event)">展开列表</span>
<tr>
<td colspan="100%">
<div id="div<%#Eval("ID") %>" style="display: none;">
<div style="float: left; font-size: small">
└</div>
<div style="border: 1 solid RGB(40,80,150); position: relative; left: 0px; overflow: auto;
width: 98%;">

<asp:GridView ID="gvInnerItem" Width="100%" Height="100%" runat="server" AutoGenerateColumns="false">
<Columns>
<asp:BoundField DataField="ID" HeaderStyle-Width="15%" HeaderText="ID">
<HeaderStyle Width="15%" />
</asp:BoundField>
<asp:BoundField DataField="姓名" HeaderStyle-Width="70%" HeaderText="姓名">
<HeaderStyle Width="70%" />
</asp:BoundField>
</Columns>
</asp:GridView>
</div>
</div>
</td>
</tr>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

后台代码：

后台代码

1 protected void Page_Load(object sender, EventArgs e)
2 {
3 BindData();
4 }
5
6 //绑定外层Gridview列表
7 public void BindData()
8 {
9 gvItem.DataSource = CommonClass.GetData("外层表格");
10 gvItem.DataBind();
11 }
12
13 //绑定嵌套的Gridview列表
14 protected void gvItem_RowCommand(object sender, GridViewRowEventArgs e)
15 {
16 if (e.Row.RowType == DataControlRowType.DataRow)
17 {
18 GridView oGridView = (GridView)e.Row.FindControl("gvInnerItem");
19 if (oGridView != null)
20 {
21 int id = Convert.ToInt32(gvItem.DataKeys[e.Row.RowIndex].Value);
22 oGridView.DataSource = CommonClass.GetData("内层表格ID=" + id);
23 oGridView.DataBind();
24 }
25 }
26 }
