Accessing DataItem in Rotator

[Viktor Takacs]

Hi,
I am trying to manipulate some controls of a RotatorItem in the ItemDataBound event. However, the e.Item.DataItem seems to be of type XmlDataSourceNodeDescriptor, with which I can't do much since it's a sealed class. I can see all my data there while debugging, but cannot access them. Any idea how? Fo example, I have a simple xml file like this:

<Images>
  <Image>
    <ImageUrl>PICT3345.jpg</ImageUrl>
  </Image>
  <Image>
    <ImageUrl>PICT4357.jpg</ImageUrl>
  </Image>
  <Image>
    <ImageUrl>PICT4479.jpg</ImageUrl>
  </Image>
  <Image>
    <ImageUrl>PICT5344.jpg</ImageUrl>
  </Image>
  <Image>
    <ImageUrl>PICT6294.jpg</ImageUrl>
  </Image>
  <Image>
    <ImageUrl>PICT6356.jpg</ImageUrl>
  </Image>
  <Image>
    <ImageUrl>PICT6898.jpg</ImageUrl>
  </Image>
  <Image>
    <ImageUrl>PICT7276.jpg</ImageUrl>
  </Image>
</Images>

(Obviously) I want to get to the InnerText of ImageUrl but I cannot.

Any help is greatly appreciated!

Hi Viktor,

Indeed, you are not supposed to be able to use the DataItem directly. Rather you should use the corresponding DataBinder class with its static Eval method. In your case this will be the XPathBinder. Here is the sample code to capture the text of the ImageUrl element:

var imageUrl = XPathBinder.Eval(e.Item.DataItem, "ImageUrl");

Hope this helps.
