没有找到记录

< / table>
< / EmptyDataTemplate>
< / asp：GridView>
< / div>
我将这个网格绑定到一个数据源。现在，我想从gridview的最后一个填充行中获取USER_ACTIVITIES_ID的值。我正在使用hiddenfield来保存此id并将其用于项目中使用javascript的其他目的。但是，我的问题是我没有获得ID的价值（无论是后端编码还是JavaScript）。任何人都可以告诉我在哪个事件或代码中，我可以得到这个值吗？请，我非常需要它。
解决方案
试试这个：
int lastrow = grdPrevious.Rows.Count - 1;
Label lb =（Label）grdPrevious.Rows [lastrow] .FindControl（Label5）;
Response.Write（lb.Text）;
Friends, I've a gridview in my web-page designed in the following manner:-
<div id="divProducts" style="height:200px; overflow:auto">
<asp:GridView ID="grdPrevious" runat="server" Width="100%"
AutoGenerateColumns="false" ShowHeader="false" GridLines="None"
ShowFooter="true" AllowPaging="false">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<tr>
<td style="width:20%; visibility:hidden">
<label class="labelHead">Activity Id </label>
</td><td></td>
<td style="width:80%; visibility:hidden">
<asp:Label ID="Label5" runat="server"
Text='<%# Eval("USER_ACTIVITIES_ID") %>'
CssClass="labelCss"></asp:Label>
</td>
</tr>
<tr>
<td style="width:20%" >
<label class="labelHead">Date </label>
</td><td>:</td>
<td style="width:80%">
<asp:Label ID="Label1" runat="server"
Text='<%# Eval("ACTIVITY_DATE1") %>'
CssClass="labelCss"></asp:Label>
</td>
</tr>
<tr>
<td>
<label class="labelHead">Interaction Type </label>
</td>
<td>:</td>
<td>
<asp:Label ID="Label2" runat="server"
Text='<%# Eval("INTERFACE_DESCRIPTION") %>'
CssClass="labelCss" ></asp:Label>
</td>
</tr>
<tr>
<td>
<label class="labelHead">Prospect</label>
</td>
<td>:</td>
<td>
<asp:Label ID="Label3" runat="server"
Text='<%# Eval("PROSPECT_DESCRIPTION") %>'
CssClass="labelCss"></asp:Label>
</td>
</tr>
<tr>
<td valign="top" >
<label class="labelHead">Note </label>
</td>
<td valign="top">:</td>
<td valign="top">
<asp:Label ID="Label4" runat="server"
Text='<%# Eval("NOTES") %>' CssClass="labelCss">
</asp:Label>
</td>
</tr>
<tr>
<td colspan="3"><hr size="1px" color="#D5DEA1"
style="margin:10px 0px;" />
</td>
</tr>
</ItemTemplate>
<ItemStyle Font-Names="Trebuchet MS;" />
</asp:TemplateField>
</Columns>
<EmptyDataTemplate>
<table width="100%" cellpadding="0" cellspacing="0" border="0">
<tr>
<td align="center" class="gridViewNoRecords">
No Records found
</td>
</tr>
</table>
</EmptyDataTemplate>
</asp:GridView>
</div>
I'm binding this grid with a datasource. Now,I want to get the value of "USER_ACTIVITIES_ID" from the last populated row of the gridview. I'm using hiddenfield to hold this id and use it for other purpose in the project using javascript. But,my problem is I'm not getting the ID's value(neither by back-end coding nor by javascript). Can anyone tell me in which event or by code,I can get this value?Please,I need it badly. Thanks in advance.
解决方案
Try this:
int lastrow = grdPrevious.Rows.Count - 1;
Label lb = (Label)grdPrevious.Rows[lastrow].FindControl("Label5");
Response.Write(lb.Text);
