如何在运行时动态分发xap文件

在我的应用程序中，我从某个信息中心下载一些 xml 数据文件，将包含图像的列添加到此 xml 文件（在 aspx.cs 中），然后将所有内容一起传递到 aspx 文件中的 GridView。

我想对 xap 文件做同样的事情 - 我需要根据数据上下文将它们添加到 GridView 中，但不幸的是有一个问题 - 对象没有像图像这样的 object.Attributes 。

这是我添加图像的代码（gvCurrency 是一个 GridView）：

for (int i = 0; i < currency.Count; i++)
{
  Image image = new Image();
  image.Attributes.Add("src", "Images/Currency/" + xdoc.GetElementsByTagName("CURRENCYCODE")[i].InnerText + ".gif");
  image.Attributes.Add("height", "15px");
  image.Attributes.Add("width", "21px");
  gvCurrency.Rows[i].Cells[0].Controls.Add(image);
}

我认为另一种可能性是将链接绑定到 aspx 文件中相应的 xap 文件，在这种情况下应该看起来像这样（如果我没记错的话）：

<asp:GridView ID="gvCurrency" runat="server"  AutoGenerateColumns="False" ...>
  <Columns>
    <asp:BoundField DataField="FLAG" />
    <asp:BoundField HeaderText="Currency Name" DataField="NAME" />
    ...
    <asp:TemplateField >
      <ItemTemplate>
        <div id="silverlightControlHost">
          <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="10px" height="10px">
          <param name="source" value="ClientBin/ArrowTriangle.xap"/>
          ...
        </div>
      </ItemTemplate>
    </asp:TemplateField >
  </Columns>
</asp:GridView>

所以，我的问题是：如何在运行时动态分发 xap 文件（在第一种情况下）以及如何将链接绑定到 xap 文件（在第二种情况下）？

谢谢。

原文

In my application I download some xml data file from some information center, add to this xml file (in aspx.cs) the column with images and all together I pass to the GridView in aspx file.

The same I want to do with xap files - I need to add them to the GridView according to the data context, but unfortunately there is a problem - object doesn't have object.Attributes like image.

Here is my code for adding images (gvCurrency is a GridView):

for (int i = 0; i < currency.Count; i++)
{
  Image image = new Image();
  image.Attributes.Add("src", "Images/Currency/" + xdoc.GetElementsByTagName("CURRENCYCODE")[i].InnerText + ".gif");
  image.Attributes.Add("height", "15px");
  image.Attributes.Add("width", "21px");
  gvCurrency.Rows[i].Cells[0].Controls.Add(image);
}

Another possibility, as I think, is in binding links to the corresponding xap files in the aspx file, that in this case should seems like this (if I am not wrong):

<asp:GridView ID="gvCurrency" runat="server"  AutoGenerateColumns="False" ...>
  <Columns>
    <asp:BoundField DataField="FLAG" />
    <asp:BoundField HeaderText="Currency Name" DataField="NAME" />
    ...
    <asp:TemplateField >
      <ItemTemplate>
        <div id="silverlightControlHost">
          <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="10px" height="10px">
          <param name="source" value="ClientBin/ArrowTriangle.xap"/>
          ...
        </div>
      </ItemTemplate>
    </asp:TemplateField >
  </Columns>
</asp:GridView>

So, my question is: how can I distribute xap files dynamically in runtime (in the first case) and how I can bind links to xap files (in the second case)?

Thanks.

The implementation of the code above is possible to see here: http://www.lzel.net/wf_Currency_ASP.aspx
