[英]Adding Querystring Parameter to GridView ItemTemplate
I have a gridview with a hyperlink in first column. 我在第一列中有一个带有超链接的gridview。 Upon clicking the hyperlink, the user is redirected to Vendor.aspx.
单击超链接后,用户将重定向到Vendor.aspx。 Now, I need to pass the consumer id (of the clicked row) as a query string to the Vendor.aspx.
现在,我需要将消费者ID(被点击的行)作为查询字符串传递给Vendor.aspx。
What is the best method to achieve it? 实现它的最佳方法是什么? Is there a way in which we can handle it using markup code only?
有没有办法只使用标记代码来处理它?
<asp:GridView ID="grdConsumers" runat="server" AutoGenerateColumns="False"
EnableViewState="True" >
<Columns>
<asp:TemplateField HeaderText="ConsumerID" SortExpression="ConsumerID" >
<ItemTemplate>
<asp:HyperLink ID="lnkConsumerID" href="Vendor.aspx" runat="server"><%# Eval("ConsumerID")%></asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField HeaderText="Status" DataField="Status" SortExpression="Status"></asp:BoundField>
</Columns>
</asp:GridView>

Try using the DataNavigateUrlFormatString
尝试使用
DataNavigateUrlFormatString
<ItemTemplate>
<asp:HyperLinkField DataNavigateUrlFields="ConsumerID" DataTextField="ConsumerID" DataNavigateUrlFormatString="Vendor.aspx?id={0}" />
</ItemTemplate>
... it will spare you Eval()
and the problem with single/double quotes when putting it inside your href
. ...当它放入你的
href
时,它将为你提供Eval()
以及单/双引号的问题。
You can substitute the DataTextField
if you like - I just put the ConsumerID there to be consistent with your example. 如果您愿意,可以替换
DataTextField
- 我只是将ConsumerID放在那里以与您的示例保持一致。
Rewrite your hyperlink in gridview in .aspx file like this: 在.aspx文件中重写gridview中的超链接,如下所示:
<asp:HyperLink ID="lnkConsumerID" runat="server" Text='<%# Eval("ConsumerID")%>' />
Then in code-behind create a RowDataBound event handler: 然后在代码隐藏中创建一个RowDataBound事件处理程序:
protected void grdConsumers_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType != DataControlRowType.DataRow) return;
var hlnkhlnk = (HyperLink)e.Row.FindControl("lnkConsumerID");
if (hlnkhlnk != null)
{
hlnkhlnk.NavigateUrl = "Vendor.aspx" + "?Consumer ID=" + hlnkhlnk.Text;
}
}
Hope it helps. 希望能帮助到你。
You can do same using at Grid view Item Data Bound Event
您可以在
Grid view Item Data Bound Event
protected void grdConsumers_ItemDataBound(object sender,DataGridItemEventArgs e)
{
if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
// Get your consumerId here
((HyperLink)e.Item.FindControl("Edit")).NavigateUrl = "Vendor.aspx?id=" + consumerId
}
}
