如何让grdview列超链接到其他页面？

Question

我有来自sql的数据源的网格视图。目前，其中一个栏目，它是总保证人，所有的数据都链接到相同的页面。但我想让标题“Total column”超链接或可点击到其他页面，而不是Total Guarantor列中的数据。

下面是我使用的代码：

           <asp:HyperLinkField DataTextField="Total Guarantor" DataNavigateUrlFields="Total Guarantor"  DataNavigateUrlFormatString="guarantoedetails.aspx?custno={0}" Text="Total Guarantor" HeaderText="Total Guarantor" />

为此，您可以使用OnRowCreated事件。

protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
{
    //check if the row is the header row
    if (e.Row.RowType == DataControlRowType.Header)
    {
        //the header cell number where to put the link
        int cellNumber = 1;

        //cast the cell in the header
        TableCell headerCell = e.Row.Cells[cellNumber];

        //create a hyperlink
        HyperLink link = new HyperLink();
        link.Text = "myLink";
        link.NavigateUrl = "/otherPage.aspx";

        //remove existing controls from the cell
        headerCell.Controls.Clear();

        //add the hyperlink to the cell
        headerCell.Controls.Add(link);
    }
}

VB

Protected Sub GridView1_RowCreated(ByVal sender As Object, ByVal e As GridViewRowEventArgs)
    'check if the row is the header row
    If (e.Row.RowType = DataControlRowType.Header) Then
        'the header cell number where to put the link
        Dim cellNumber As Integer = 1

        'cast the cell in the header
        Dim headerCell As TableCell = e.Row.Cells(cellNumber)

        'create a hyperlink
        Dim link As HyperLink = New HyperLink
        link.Text = "myLink"
        link.NavigateUrl = "/otherPage.aspx"

        'remove existing controls from the cell
        headerCell.Controls.Clear

        'add the hyperlink to the cell
        headerCell.Controls.Add(link)
    End If        
End Sub
