Question

我试图在超链接字段中添加到导航网址。

我的gridview上有5列，最后一列是

  <asp:HyperLinkField DataNavigateUrlFields="vID" 
            DataNavigateUrlFormatString="Page2.aspx?field={0}" HeaderText="send" 
            Text="send"></asp:HyperLinkField>

以及添加到其后面的代码

Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound

    Dim hk As HyperLink = DirectCast(e.Row.Cells(4).Controls(0), HyperLink)
    hk.NavigateUrl += "&TN=table1"

End Sub

我昨天有工作，但必须不小心删除了代码，我无法在这里找到错误的地方，我收到错误“指定的参数超出了有效值的范围。参数名称：索引“

您必须检查RowType，否则您也会在标题中查找HyperLink。

VB

Protected Sub GridView1_RowDataBound(sender As Object, e As GridViewRowEventArgs )
    If e.Row.RowType = DataControlRowType.DataRow Then
        Dim link = DirectCast(e.Row.Cells(4).Controls(0), HyperLink)
        link.NavigateUrl &= "&TN=table1"
    End If
End Sub

C＃

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        HyperLink link = (HyperLink)e.Row.Cells[4].Controls[0];
        link.NavigateUrl += "&TN=table1";
    {
}
