如何在GridView的TemplateField中find控件？
FindControl方法如何工作，如果我需要find在GridView Template ，更具体的ItemTemplate内的任何Control ？
我有一个hyperlink但它不能find相同的。
问题更新了代码
GridView代码如下：
<asp:GridView ID="grvYourOpportunities" runat="server" AllowPaging="True" AutoGenerateColumns="False" DataKeyNames="ID#,B,H" PageSize="20" CellPadding="4" ForeColor="#333333" GridLines="Both" OnRowDataBound="grvYourOpt_RowDataBound"> <HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" /> <RowStyle BackColor="#F7F6F3" ForeColor="#333333" /> <Columns> <asp:TemplateField> <HeaderTemplate> i </HeaderTemplate> <ItemTemplate> <%# Eval("i") %> </ItemTemplate> </asp:TemplateField> <asp:TemplateField> <HeaderTemplate> H </HeaderTemplate> <ItemTemplate> <%--<a href="javascript:ShowChildGrid('div<%# Eval("ID#") %>');"> <img id="imgdiv<%# Eval("ID#") %>" alt="Click" border="0" src="plus.gif" runat="server" /> </a> --%> <asp:HyperLink runat="server" ID="hlPlus" ImageUrl="~/plus.gif"></asp:HyperLink> </ItemTemplate> </asp:TemplateField> <asp:TemplateField> <HeaderTemplate> B </HeaderTemplate> <ItemTemplate> <%--<%# Eval("B") %>--%> <a href="javascript:ShowChildGridForBCol('div1<%# Eval("ID#") %>');"> <img id="imgdiv1<%# Eval("ID#") %>" alt="Click here" border="0" src="tempY.png" /> </a> </ItemTemplate> </asp:TemplateField> <asp:TemplateField> <HeaderTemplate> ID.Nr. </HeaderTemplate> <ItemTemplate> <%# Eval("ID#")%> </ItemTemplate> </asp:TemplateField> <asp:TemplateField> <HeaderTemplate> Entry Date </HeaderTemplate> <ItemTemplate> <%# Eval("Entry Date") %> </ItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderStyle-Width="20px" ItemStyle-Width="20px"> <HeaderTemplate> BU </HeaderTemplate> <ItemTemplate> <%# Eval("BU")%> </ItemTemplate> </asp:TemplateField> <asp:TemplateField> <HeaderTemplate> BE </HeaderTemplate> <ItemTemplate> <%# Eval("BE")%> </ItemTemplate> </asp:TemplateField> <asp:TemplateField> <HeaderTemplate> Product Family </HeaderTemplate> <ItemTemplate> <%# Eval("Product Family")%> </ItemTemplate> </asp:TemplateField> <asp:TemplateField> <HeaderTemplate> Project Name </HeaderTemplate> <ItemTemplate> <%# Eval("Project Name")%> </ItemTemplate> </asp:TemplateField> <asp:TemplateField> <HeaderTemplate> SOP </HeaderTemplate> <ItemTemplate> <%# Eval("SOP")%> </ItemTemplate> </asp:TemplateField> <asp:TemplateField> <HeaderTemplate> Award Date </HeaderTemplate> <ItemTemplate> <%# Eval("Award Date")%> </ItemTemplate> </asp:TemplateField> <asp:TemplateField> <HeaderTemplate> Milestone Next Date </HeaderTemplate> <ItemTemplate> <%# Eval("Milestone Next Date")%> </ItemTemplate> </asp:TemplateField> <asp:TemplateField> <HeaderTemplate> Contract Status </HeaderTemplate> <ItemTemplate> <%# Eval("Contract Status")%> </ItemTemplate> </asp:TemplateField> <asp:TemplateField> <HeaderTemplate> Prob.Of Success </HeaderTemplate> <ItemTemplate> <%# Eval("ProbSuccess")%> </ItemTemplate> </asp:TemplateField> <asp:TemplateField> <HeaderTemplate> Key Account </HeaderTemplate> <ItemTemplate> <%# Eval("Key Account")%> </ItemTemplate> </asp:TemplateField> <asp:TemplateField> <HeaderTemplate> Sales SubRegion </HeaderTemplate> <ItemTemplate> <%# Eval("Sales SubRegion")%> </ItemTemplate> </asp:TemplateField> <asp:TemplateField> <HeaderTemplate> Growth </HeaderTemplate> <ItemTemplate> <%# Eval("Growth")%> </ItemTemplate> </asp:TemplateField> <asp:TemplateField> <HeaderTemplate> Sales paOE mio$ </HeaderTemplate> <ItemTemplate> <%# Eval("SalesOE")%> </ItemTemplate> </asp:TemplateField> <asp:TemplateField> <HeaderTemplate> Sales paAM mio$ </HeaderTemplate> <ItemTemplate> <%# Eval("SalesAM")%> </ItemTemplate> </asp:TemplateField> <%--GridView 2, 3--%> <asp:TemplateField> <ItemTemplate> <tr> <td align="left" style="margin-left: 10px;" colspan="5"> <div id="div<%# Eval("ID#") %>" style="display: none; position: relative; left: 110px;"> <asp:GridView ID="GridView2" runat="server" Width="40%" AutoGenerateColumns="false" DataKeyNames="Entry Date" EmptyDataText="No orders for this customer."

hyperlink hlPlus是GridView的模板字段（Item Template）中的hyperlink字段。
尝试这个：
foreach(GridViewRow row in GridView1.Rows) { if(row.RowType == DataControlRowType.DataRow) { HyperLink myHyperLink = row.FindControl("myHyperLinkID") as HyperLink; } }
如果你正在处理RowDataBound事件，就像这样：
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { if(e.Row.RowType == DataControlRowType.DataRow) { HyperLink myHyperLink = e.Row.FindControl("myHyperLinkID") as HyperLink; } }
您可以使用此代码在GridView中查找HyperLink 。 使用e.Row.Cells[0].Controls[0]在GridView中查找控件的第一个位置。
protected void AspGrid_RowDataBound(object sender, GridViewRowEventArgs e) { if(e.Row.RowType == DataControlRowType.DataRow) { DataRowView v = (DataRowView)e.Row.DataItem; if (e.Row.Cells.Count > 0 && e.Row.Cells[0] != null && e.Row.Cells[0].Controls.Count > 0) { HyperLink link = e.Row.Cells[0].Controls[0] as HyperLink; if (link != null) { link.Text = "Edit"; } } } }
我已经做了访问单元格控件内的控件。 在所有控制集合中查找。
ControlCollection cc = (ControlCollection)e.Row.Controls[1].Controls; Label lbCod = (Label)cc[1];
如果你的GridView是数据绑定的，你可以在结果集里做一个索引列，像这样：
select row_number() over(order by YourIdentityColumn asc)-1 as RowIndex, * from YourTable where [Expresion]
在要使用的命令控件中，使CommandArgument属性的值等于DataSet表RowIndex的行索引，如下所示：
<asp:LinkButton ID="lbnMsgSubj" runat="server" Text='<%# Eval("MsgSubj") %>' Font-Underline="false" CommandArgument='<%#Eval("RowIndex") %>' />
使用OnRowCommand事件触发点击链接button，如下所示：
<asp:GridView ID="gvwStuMsgBoard" runat="server" AutoGenerateColumns="false" GridLines="Horizontal" BorderColor="Transparent" Width="100%" OnRowCommand="gvwStuMsgBoard_RowCommand">
最后，当你触发这个事件时，你后面的代码可以做任何你喜欢的事情：
protected void gvwStuMsgBoard_RowCommand(object sender, GridViewCommandEventArgs e) { Panel pnlMsgBody = (Panel)gvwStuMsgBoard.Rows[Convert.ToInt32(e.CommandArgument)].FindControl("pnlMsgBody"); if(pnlMsgBody.Visible == false) { pnlMsgBody.Visible = true; } else { pnlMsgBody.Visible = false; } }
string textboxID; string da; textboxID = "ctl00$MainContent$grd$ctl" + (grd.Columns.Count + j).ToString() + "$txtDyna" + (k).ToString(); textboxID= ctl00$MainContent$grd$ctl12$ctl00; da = Request.Form(textboxID);
