如果我需要查找FindControl Control内的任何GridView，更具体地Template，那么ItemTemplate方法如何运作？
我有hyperlink，但无法找到相同的内容。
问题已更新为代码
GridView代码如下：

hyperlink是hlPlus的模板字段（项目模板）中的hyperlink字段。
答案 0 :(得分：50)
试试这个：
foreach(GridViewRow row in GridView1.Rows) {
if(row.RowType == DataControlRowType.DataRow) {
HyperLink myHyperLink = row.FindControl("myHyperLinkID") as HyperLink;
}
}
如果您正在处理RowDataBound事件，它就像这样：
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.DataRow)
{
HyperLink myHyperLink = e.Row.FindControl("myHyperLinkID") as HyperLink;
}
}
答案 1 :(得分：1)
您可以使用此代码在GridView中查找HyperLink。使用e.Row.Cells[0].Controls[0]在GridView中找到第一个控件位置。
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";
}
}
}
}
答案 2 :(得分：1)
我已经完成了访问单元格控件中的控件。查找所有控件集合。
ControlCollection cc = (ControlCollection)e.Row.Controls[1].Controls;
Label lbCod = (Label)cc[1];
答案 3 :(得分：0)
protected void gvTurnos_RowDataBound(object sender, GridViewRowEventArgs e)
{
try
{
if (e.Row.RowType == DataControlRowType.EmptyDataRow)
{
LinkButton btn = (LinkButton)e.Row.FindControl("btnAgregarVacio");
if (btn != null)
{
btn.Visible = rbFiltroEstatusCampus.SelectedValue == "1" ? true : false;
}
}
}
catch (Exception ex)
{
throw ex;
}
}
答案 4 :(得分：0)
尝试以下代码。
类似于LinkButton，Label，HtmlAnchor和HtmlInputControl中的GridView。
<asp:GridView ID="mainGrid" runat="server" AutoGenerateColumns="false" CssClass="table table-bordered table-hover tablesorter"
OnRowDataBound="mainGrid_RowDataBound" EmptyDataText="No Data Found.">
<Columns>
<asp:TemplateField HeaderText="HeaderName" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:Label runat="server" ID="lblName" Text=' <%# Eval("LabelName") %>'></asp:Label>
<asp:LinkButton ID="btnLink" runat="server">ButtonName</asp:LinkButton>
<a href="javascript:void(0);" id="btnAnchor" runat="server">ButtonName</a>
<input type="hidden" runat="server" id="hdnBtnInput" value='<%#Eval("ID") %>' />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
处理RowDataBound事件，
protected void mainGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Label lblName = (Label)e.Row.FindControl("lblName");
LinkButton btnLink = (LinkButton)e.Row.FindControl("btnLink");
HtmlAnchor btnAnchor = (HtmlAnchor)e.Row.FindControl("btnAnchor");
HtmlInputControl hdnBtnInput = (HtmlInputControl)e.Row.FindControl("hdnBtnInput");
}
}
答案 5 :(得分：-1)
如果您的GridView是数据库，请在结果集中创建一个索引列，如下所示：
select row_number() over(order by YourIdentityColumn asc)-1 as RowIndex, * from YourTable where [Expresion]
在命令控件中你想使用make的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") %>' />
单击链接按钮时触发OnRowCommand事件：
<asp:GridView ID="gvwStuMsgBoard" runat="server" AutoGenerateColumns="false" GridLines="Horizontal" BorderColor="Transparent" Width="100%" OnRowCommand="gvwStuMsgBoard_RowCommand">
最后，当您触发事件时，您背后的代码可以做任何您喜欢的事情：
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;
}
}
