  ReadXml problem

  Sep 30, 2003 08:23 PM|LINK

  HI, i'm kinda new to ASP.NET and must do a project including webservices and a client site so i already made the webservice wich outputs strings in XML format now i want that string to be binded to a datagrid, does anyone know how i can do this? I created this in my aspx page : protected DataGrid DG; private void Page_Load(object sender, System.EventArgs e) { wsProduct.Product myservice = new wsProduct.Product(); //the proxy to the webservice string cataloog = myservice.getCatalogue(); //retrieve webmethod and put the xml in string DataSet mydataset = new DataSet(); mydataset.ReadXml(cataloog); // here i got the problem DG.DataSource = mydataset.Tables[0].DefaultView; DG.DataBind(); } Ok, ReadXml think "cataloog" is a file, so i get the follwing error : Exception Details: System.IO.PathTooLongException: The path is too long after being fully qualified. Make sure path is less than 260 characters. I searched on this forum about possible solution, but couldn't find it Does anyone have a possible one? Thanks in advance

  Your web service can return a DataSet, which can be consumed by your DataGrid, so you would be able to just have: myDataSet = myService.GetCatalogue()

  Yes I know but the project demands that the webservice outputs an XML isn't there any option in my case to display that xml in an aspx page? Thx

  DataSet doesn't have a function that interprets a string as an XML stream, but it does have a ReadXml() overload that takes a TextReader, so just use the StringReader implementation:

  protected DataGrid DG;
  private void Page_Load(object sender, System.EventArgs e)
  {
  	wsProduct.Product myservice = new wsProduct.Product(); //the proxy to the webservice
  	string cataloog = myservice.getCatalogue(); //retrieve webmethod and put the xml in string
  	DataSet mydataset = new DataSet();
  	mydataset.ReadXml(new StringReader(cataloog)); // here i got the problem
  	DG.DataSource = mydataset.Tables[0].DefaultView;
  	DG.DataBind();
  }
