Question

我已经将datagridview绑定到数据库，我正在尝试设置datanavigateurlfields属性。我可以在值直接来自数据库时设置值，但我想连接一些常量字符串，如“edit_profile.aspx +？ uid“+ [数据库中的值] ，现在当我尝试将”edit_profile.aspx +？uid“添加到双引号中的url时，它将此字符串视为数据库列，当我尝试将此值设置为是单引号它给了我解析器错误。

这是我的代码：

<Columns>
            <asp:hyperlinkfield datatextfield="heading"
            datanavigateurlfields="heading"          
            headertext="Title"
            target="_blank"

             />

我正在尝试将某些值与datanavigateurlfield中的“heading”连接起来。请告诉我如何实现这一目标。

你可以这样做....

      <asp:gridview id="OrdersGridView" 
        datasourceid="OrdersSqlDataSource" 
        autogeneratecolumns="false"
        runat="server">

        <columns>

          <asp:boundfield datafield="OrderID" 
            headertext="Order ID"/>
          <asp:boundfield datafield="ProductID" 
            headertext="Product ID"/>
          <asp:hyperlinkfield datatextfield="UnitPrice"
            datatextformatstring="{0:c}"
            datanavigateurlfields="ProductID"
            datanavigateurlformatstring="~\details.aspx?ProductID={0}"          
            headertext="Price"
            target="_blank" />
          <asp:boundfield datafield="Quantity" 
            headertext="Quantity"/>

        </columns>

      </asp:gridview>

      <!-- This example uses Microsoft SQL Server and connects -->
      <!-- to the Northwind sample database.                   -->
      <asp:sqldatasource id="OrdersSqlDataSource"  
        selectcommand="SELECT [OrderID], [ProductID], [UnitPrice], [Quantity] FROM [Order Details]"
        connectionstring="server=localhost;database=northwind;integrated security=SSPI"
        runat="server">
      </asp:sqldatasource>

    </form>
  </body>
</html>

在asp.net中的datanavigateurlfields中组合了多个值
