DataRow（数据表）中的链接

我正在动态构建一个数据表，并尝试在要添加到数据表的数据行中添加一个“链接”。 DataTable 在创建后绑定到 GridView。

类似这样的事情：

   DataTable dataTable = new DataTable();
   foreach (Item item in items)
    {
        DataRow row = dataTable.NewRow();
        dataTable.Columns.Add(new DataColumn("col"));

        row["col"] = "<a href='http://www.google.com'>Link here</a>";

        dataTable.Rows.Add(row);

    }

然后我将它绑定到 GridView ：

        <asp:GridView ID="grdView" Runat="server" border="0" EnableViewState="true" style="width:100%;"
            AutoGenerateColumns="true" AllowPaging="false" PagerSettings-Visible="false" 
            ShowHeader="true" ShowFooter="true" CellPadding="0" CellSpacing="0"
            Visible="True">
        </asp:GridView>

但是当我将它绑定到 GridView 时，Column 中的 HTML 会被编码。有没有办法在那里添加超链接对象或类似的东西？

PS 它不在示例中，但列是动态添加的（这意味着我在渲染之前不知道我将拥有多少列）

更新＃1

当我创建列。我能够做类似的事情：

    dataTable.Columns.Add(new DataColumn("col"));

    BoundField bf = new BoundField();
    bf.HtmlEncode = false;
    bf.DataField = "col";
    grd.Columns.Add(bf);

   row["col"] = "<a href='http://www.google.com'>Link here</a>";

但它显示 2 列“col”...

更新＃3： 我改用了 DataGrid。当插入数据行中的“纯文本”时，它不会对 HTML 进行编码。

I'm building a DataTable dynamically and I'm trying to add a "link" in the DataRow(s) that I'm adding to the DataTable. The DataTable is bound to a GridView after it's creation.

Something like that :

   DataTable dataTable = new DataTable();
   foreach (Item item in items)
    {
        DataRow row = dataTable.NewRow();
        dataTable.Columns.Add(new DataColumn("col"));

        row["col"] = "<a href='http://www.google.com'>Link here</a>";

        dataTable.Rows.Add(row);

    }

Then I bind it to a GridView :

        <asp:GridView ID="grdView" Runat="server" border="0" EnableViewState="true" style="width:100%;"
            AutoGenerateColumns="true" AllowPaging="false" PagerSettings-Visible="false" 
            ShowHeader="true" ShowFooter="true" CellPadding="0" CellSpacing="0"
            Visible="True">
        </asp:GridView>

But the HTML in the Column is encoded when I bind it to the GridView.
Is there a way to add a HyperLink object there or something like that?

P.S. It's not in the example but the columns are added dynamically (it means that I don't know before the rendering how many columns I'll have)

UPDATE #1

I have access to the GridView when I create the columns.
I was able to do something like that :

    dataTable.Columns.Add(new DataColumn("col"));

    BoundField bf = new BoundField();
    bf.HtmlEncode = false;
    bf.DataField = "col";
    grd.Columns.Add(bf);

   row["col"] = "<a href='http://www.google.com'>Link here</a>";

But it displays 2 coloumns "col"...

UPDATE #3 :
I used a DataGrid instead. It doesn't encode HTML when inserted in "plain text" in the data rows.

如果您从查询中返回 html 代码，只需在绑定字段上使用 htmlEncode=False 即可。还要在您的 gridview 上设置 AutoGenerateColumns="false"，这就是您在 gridview 上获得双列的原因。

自从有人问这个问题以来已经很长时间了，但我到达这里是第一个谷歌结果之一，所以我想告诉你我已经解决了这个问题，添加了一个“HyperLinkField”：

HyperLinkField myLink = new HyperLinkField();
myLink.HeaderText = "Link Here";
myLink.DataTextField = "Click here";
myLink.DataNavigateUrlFields = new string[] { "field1", "field2", "field3" };
myLink.DataNavigateUrlFormatString = "NewPage.aspx?id={0}&otherId={1}&otherId2={2}";

myGridView.Columns.Add(myLink);

//Finally bind the data...
myGridView.DataBind();

It's been an long time since this was asked, but I arrived here being one of the first google results, so I would like to tell you that I have resolved this adding a "HyperLinkField":

HyperLinkField myLink = new HyperLinkField();
myLink.HeaderText = "Link Here";
myLink.DataTextField = "Click here";
myLink.DataNavigateUrlFields = new string[] { "field1", "field2", "field3" };
myLink.DataNavigateUrlFormatString = "NewPage.aspx?id={0}&otherId={1}&otherId2={2}";

myGridView.Columns.Add(myLink);

//Finally bind the data...
myGridView.DataBind();

抱歉，忽略...我没有看到动态表约束
为什么要在GridView中添加模板列，然后添加超链接。抱歉，此代码在此空间中似乎无法正确格式化

    <asp:TemplateColumn>                                                                        <ItemTemplate>
<asp:HyperLink runat="server" ID="hypLink" Text="test" Target='<%# DataBinder.Eval(Container.DataItem, "moved_ref_amt").ToString() %>'></asp:HyperLink>                                                                        </ItemTemplate>                                                                            </asp:TemplateColumn>

sorry disregard...I didnt see the dynamic table constraint
Why do you add a template column to the GridView and then add a hyperlink. Sorry this code wont seem to format correctly in this space

    <asp:TemplateColumn>                                                                        <ItemTemplate>
<asp:HyperLink runat="server" ID="hypLink" Text="test" Target='<%# DataBinder.Eval(Container.DataItem, "moved_ref_amt").ToString() %>'></asp:HyperLink>                                                                        </ItemTemplate>                                                                            </asp:TemplateColumn>
