Dim Ds As New DataSet

with the above example you'll have to first write your xml to a file.
If you don't want to do that, try the following:


Dim Ds As New DataSet
Ds.ReadXml(New StringReader(xmlstring))
        GridView1.DataSource = Ds
        GridView1.DataBind()


            

Not the solution you were looking for? Getting a personalized solution is easy.

Can you post a portion of what the XML looks like?  Do you have info on how the web service was developed?  If it exposes a dataset as its return type, then it might actually be very easy.  Otherwise, you will need to derive a dataset structure from the XML.  I can get you started on that, but I need to see the XML first.

you might be better off using xslt from the returned string, less overhead.

Thanks, I am able to at lease partially bind the xml to the gridview with limited results. The xml I return from my webservice is in the following format:

<Response>
  <title>title_name</title>
  <result>
   <resulttype>SUCCESS</resulttype>
   <resulttext>0123</resulttext>
   <records>
    <record>
     <id>1234</id>
     <name>John Doe</name>
     <address>1 Main Street</address>
    </record>
   <record>
     <id>1235</id>
     <name>Jane Doe</name>
     <address>2 Main Street</address>
    </record>
   </records>
  </result>
 </Response>

When I perform the bind my gridview only shows the title element. I am trying to display each record in the gridview.

Also, for anyone else viewing this issue, I am using the following method to call the webservice and retrieve the xml:

    public static DataSet getRecords(string strTitle)
    {
        DataSet myDS = new DataSet();

        // initialize object
        myWS.Service MyDNS = new myWS.Service();

        // get AccessCode from web.config file
        string AccessCode = ConfigurationManager.AppSettings["myWS.accesscode"].ToString();

        // make call to myWS webreference that returns and XmlNode
        XmlNode myXMLNodeObject = myWS.selectRecords(AccessCode,strTitle);

        // create new xmldocument object
        XmlDocument myXmlDocumentObject = new XmlDocument();

        // import node we received from mydns call
        myXmlDocumentObject.AppendChild(myXmlDocumentObject.ImportNode(myXMLNodeObject, true));

        //read xmldocument into xmlnodereader
        XmlNodeReader reader = new XmlNodeReader(myXmlDocumentObject);

        //read xml into dataset
        myDS.ReadXml(reader);

       //close reader
       reader.Close();

      //return dataset
        return myDS;
    }


Thanks for any additional insight you can offer.

Additionally, on my pageload I use:

        DataSet myDS = Tools.getRecords(strTitle);
        GridView1.DataSource = myDS;
        GridView1.DataBind();

To complete the binding.

I believe I have what I need. I have inserted the following line:


reader.ReadToFollowing("records");
myDS.ReadXml(reader);

which pushes the reader to the 'records' elements and then passes the items within the to dataset.

If anyone has something more efficient than the methods I am using it would be very much appreciated.
