看看以下代码:
<asp:HyperLinkField
DataNavigateUrlFields="NameID"
DataNavigateUrlFormatString="names.aspx?nameid={0}"
DataTextField="name"
HeaderText="Name"
ItemStyle-Width="100px"
ItemStyle-Wrap="true" />
只需要名称id即可导航到下一页。如何包含不在gridview中的其他两个参数。我正在使用的导航URL必须采用gridview中已存在的关键字和数据库表中的其他两个参数。我尝试使用所有这些代码。没有什么对我有用。
<asp:HyperLinkField DataTextField="Keyword" DataNavigateUrlFields="Keyword"
DataNavigateUrlFormatString="KeywordSrchSumDtl.aspx?Keyword={0}&State={1}&City={2}"
HeaderStyle-VerticalAlign="Bottom" ItemStyle-HorizontalAlign="center" />
我无法使用上面的代码,因为状态和城市不在GridView中,但在我的数据表中可用。
我也尝试使用以下代码,但它不起作用:
<asp:TemplateField HeaderText="Keyword" ItemStyle-HorizontalAlign="Center" FooterStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:HyperLink ID="link" runat="server" NavigateUrl='<% # "KeywordSrchSumDtl.aspx?Keyword="Eval("Keyword")+"&State="+Request.QueryString["State"]%>' Text='<%# Eval("Keyword") %>'>
</asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>
我也试过这个:
<asp:HyperLink ID="Link1" runat="Server" NavigateUrl='<%#redirectURL()+Server.UrlEncode((Eval("Keyword")).ToString())%>' Text='<%# DataBinder.Eval(Container.DataItem,"Keyword") %>'>
</asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>
.aspx.cs
return "KeywordSrchSumDtl.aspx?Keyword=" +
//I DONNO HOW TO CALL THE KEYWORD HERE//
+ "&State=" + System.Web.HttpContext.Current.Request.QueryString["State"]
+ "&City=" + System.Web.HttpContext.Current.Request.QueryString["City"];
我不知道如何解决这个问题。

将DataNavigateUrlFields
属性,逗号分隔值与"KeywordSrchSumDtl.aspx?Keyword={0}&State={1}&City={2}"
<asp:HyperLinkField DataNavigateUrlFields="Keyword,State,City"
DataNavigateUrlFormatString="KeywordSrchSumDtl.aspx?Keyword={0}&State={1}&City={2}"
Text="View Details" />

}

您可以尝试使用string.Format
方法
NavigateUrl='<%# String.Format("KeywordSrchSumDtl.aspx?Keyword={0}&State={1}&City={2}", DataBinder.Eval(Container.DataItem, "Keyword"), Request.QueryString["State"], Request.QueryString["City"]) %>'

您可以使用字符串[]
从Code Behind初始化DataNavigateUrlFields答案 3 :(得分:-1)
最后,通过以下代码导航
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
HyperLink hl = (HyperLink)e.Row.FindControl("Link");
if (hl != null)
{
DataRowView drv = (DataRowView)e.Row.DataItem;
string keyword = drv["Keyword"].ToString().Trim();
string state = strState.ToString().Trim();
string city = strCity.ToString().Trim();
hl.NavigateUrl = "KeywordSrchSumDtl.aspx?Keyword=" + keyword + "&Geo=" + geo + "&Site=" + site;
}
}
}

Some time we need to pass multiple parameters with hyperlink in Gridview, datagrid or any data list control then we can use following code:-</br>
**CODE:-**
<asp:GridView ID="gvFin" runat="server" CellPadding="1" AutoGenerateColumns="false">
<Columns>
<asp:TemplateField ItemStyle-Width="4%" HeaderStyle-Width="4%" SortExpression="CDL"
HeaderText="CDL#" HeaderStyle-Font-Bold="true">
<ItemTemplate>
<asp:HyperLink ID="lnk1" runat="server"
Text='<%# DataBinder.Eval(Container.DataItem,"TestValue") %>'
NavigateUrl='<%# "javascript:ShowACP(\"" + DataBinder.Eval(Container.DataItem, "ID") + "\",\"" + DataBinder.Eval(Container.DataItem,"ACCOUNTPLAN") + "\");" %>' ForeColor="Blue" / </ItemTemplate>
</asp:TemplateField>
**JavaScript Function**
function ShowACP(id, acplabel)
{ if (acplabel == "No")
{
window.location = "#";
}
else</br>
window.location = "Default.aspx?gid=" + id;
}
