如何将HyperLinkField NavigateURL设置为SQL列值C＃ASP.Net Web窗体

标签： c# asp.net sql-server gridview hyperlink

我正在尝试构建gridview，并且一些列需要使用HyperLinkField来显示来自一个字段的文本，同时链接到另一个字段中的文本。在这种情况下，我尝试用于NavigateURL的文本是pdf的名称。我目前用于获取HyperLinkField的NavigateURL文本的方法只是从查询中的字段中获取第一个值，因此将显示正确的文本，但NavigateURL对于除第一个值之外的所有内容都不正确。 / p>

这是aspx页面中的gridview。

<asp:GridView ID="PaperProp" RowStyle-BackColor="#f4f4f4" HeaderStyle-BackColor="#CFDBE5" runat="server" AutoGenerateColumns="False" >
                        <columns>
                        </columns>
                        </asp:GridView>

以下是我用来构建gridview的代码背后的代码

string PaperPropQuery = "SELECT bidd_number, bidd_name, bidd_desc, prebid_req, open_dt, buyer, bidd_status, Addendum FROM vPaper_Proposals ORDER BY CONVERT(DateTime, open_dt,101) DESC";
        SqlCommand cmd2 = new SqlCommand(PaperPropQuery, new SqlConnection(ConStr));

        cmd2.Connection.Open();
        var cmdr2 = cmd2.ExecuteReader();

            if (cmdr2.Read())
            {
                LinkField = new HyperLinkField();

                LinkField.HeaderText = "RFP No.";
                LinkField.DataTextField = "bidd_number";
                LinkField.HeaderStyle.CssClass = "GVpadding";
                LinkField.ItemStyle.CssClass = "GVpadding";
                LinkField.NavigateUrl = "./bids/" + cmdr2["bidd_name"].ToString();
                LinkField.Target = "_blank";

                PaperProp.Columns.Add(LinkField);

                TextField = new BoundField();

                TextField.HeaderText = "Description";
                TextField.DataField = "bidd_desc";
                TextField.HeaderStyle.CssClass = "GVpadding";
                TextField.ItemStyle.CssClass = "GVpadding";

                PaperProp.Columns.Add(TextField);

                LinkField = new HyperLinkField();

                LinkField.HeaderText = "PreBid";
                LinkField.DataTextField = "prebid_req";
                LinkField.HeaderStyle.CssClass = "GVpadding";
                LinkField.ItemStyle.CssClass = "GVpadding";

                PaperProp.Columns.Add(LinkField);

                TextField = new BoundField();

                TextField.HeaderText = "Open Date";
                TextField.DataField = "open_dt";
                TextField.HeaderStyle.CssClass = "GVpadding";
                TextField.ItemStyle.CssClass = "GVpadding";

                PaperProp.Columns.Add(TextField);

                LinkField = new HyperLinkField();

                LinkField.HeaderText = "Buyer";
                LinkField.DataTextField = "buyer";
                LinkField.HeaderStyle.CssClass = "GVpadding";
                LinkField.ItemStyle.CssClass = "GVpadding";
                LinkField.NavigateUrl = "";

                PaperProp.Columns.Add(LinkField);

                TextField = new BoundField();

                TextField.HeaderText = "Status";
                TextField.DataField = "bidd_status";
                TextField.HeaderStyle.CssClass = "GVpadding";
                TextField.ItemStyle.CssClass = "GVpadding";

                PaperProp.Columns.Add(TextField);

                LinkField = new HyperLinkField();

                LinkField.HeaderText = "Addendum";
                LinkField.DataTextField = "Addendum";
                LinkField.HeaderStyle.CssClass = "GVpadding";
                LinkField.ItemStyle.CssClass = "GVpadding";

                PaperProp.Columns.Add(LinkField);

                cmdr2.Close();

                PaperProp.DataSource = cmd2.ExecuteReader();
                PaperProp.DataBind();

                cmd2.Connection.Close();
                cmd2.Connection.Dispose();
            }
            else
            {
                PaperProplbl.Text = "None at this time.";
            }

我编码不多，而且我对C＃很陌生，所以我知道这可能是查询数据库和构建网格视图的一种可怕方式，因为我对任何一个开放关于如何改进代码的建议，但我的主要问题是如何获得

LinkField.NavigateUrl =“./ bids /”+ cmdr2 [“bidd_name”]。ToString（）;

包含字段中每行的bidd_name而不是第一行？

找到我自己的答案。您可以使用DataNavigateUrlFields和DataNavigateUrlFormatString来创建表示查询数据的URL。
