hlPlus
是GridView
的模板字段（项目模板）中的hyperlink
字段。请尝试以下操作：
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，则如下所示：
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.DataRow)
{
HyperLink myHyperLink = e.Row.FindControl("myHyperLinkID") as HyperLink;
}
}
select row_number() over(order by YourIdentityColumn asc)-1 as RowIndex, * from YourTable where [Expresion]
<asp:LinkButton ID="lbnMsgSubj" runat="server" Text='<%# Eval("MsgSubj") %>' Font-Underline="false" CommandArgument='<%#Eval("RowIndex") %>' />
<asp:GridView ID="gvwStuMsgBoard" runat="server" AutoGenerateColumns="false" GridLines="Horizontal" BorderColor="Transparent" Width="100%" OnRowCommand="gvwStuMsgBoard_RowCommand">
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;
}
}
如果GridView是databond，请在检索的结果集中创建一个索引列，如下所示：
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.DataRow)
{
HyperLink myHyperLink = e.Row.FindControl("myHyperLinkID") as HyperLink;
}
}
select row_number() over(order by YourIdentityColumn asc)-1 as RowIndex, * from YourTable where [Expresion]
<asp:LinkButton ID="lbnMsgSubj" runat="server" Text='<%# Eval("MsgSubj") %>' Font-Underline="false" CommandArgument='<%#Eval("RowIndex") %>' />
<asp:GridView ID="gvwStuMsgBoard" runat="server" AutoGenerateColumns="false" GridLines="Horizontal" BorderColor="Transparent" Width="100%" OnRowCommand="gvwStuMsgBoard_RowCommand">
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;
}
}
在要使用的命令控件中，使CommandArgument属性的值等于数据集表RowIndex的行索引，如下所示：
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.DataRow)
{
HyperLink myHyperLink = e.Row.FindControl("myHyperLinkID") as HyperLink;
}
}
select row_number() over(order by YourIdentityColumn asc)-1 as RowIndex, * from YourTable where [Expresion]
<asp:LinkButton ID="lbnMsgSubj" runat="server" Text='<%# Eval("MsgSubj") %>' Font-Underline="false" CommandArgument='<%#Eval("RowIndex") %>' />
<asp:GridView ID="gvwStuMsgBoard" runat="server" AutoGenerateColumns="false" GridLines="Horizontal" BorderColor="Transparent" Width="100%" OnRowCommand="gvwStuMsgBoard_RowCommand">
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;
}
}
您可以使用此代码在GridView中查找超链接。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";
}
}
}
}
我已经访问了cell控件中的控件。在所有控件集合中查找
ControlCollection cc = (ControlCollection)e.Row.Controls[1].Controls;
Label lbCod = (Label)cc[1];
试试下面的代码
与LinkButton、Label、HtmlAnchor和HtmlInputControl中的GridView类似
<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>
你能将“HyperLink lnk=（HyperLink）e.Row.FindControl（“hlPlus”）；“EXTER”if（colH=“1”）”？如果你按照我的建议，你的代码应该可以工作，你确定你提供了正确的ID吗？是的，我提供了正确的ID。我想你的代码应该包括e.Row.FindControl，而不是Row.FindControl，我相信您知道超链接在gridview控件的项目模板中是的，很抱歉，我的第二个代码应该是“e.Row.FindControl”，但您的代码已经有了。
