Format XML data to display on a gridview - asp.net

Question

I am trying to format XML data to display on a grid.
Page1.aspx. This inserts XML data stored a xmldatatype:
WorkHistory workhis = js.Deserialize<WorkHistory>(json);
XmlDocument work = (XmlDocument)JsonConvert.DeserializeXmlNode(json, "root");
objBLL.insert_XMLWork(work, Convert.ToInt64(ui.id));
Page2.aspx retrieves it and display on a grid:
DataTable FBWorkDt = objBLL.get_FacebookWork(FacebookUserId);
GrdWork.DataSource = FBWorkDt;
GrdWorkPub.DataBind();
get_FacebookWork(select workinfo from Fprofiles where Userid = FacebookUserId)
returns a DataTable
It displays in this format exactly.
WorkInfo
<root><work><employer><id>208571635850052</id><name>Netizen Apps</name></employer></work><id>1076483621</id></root>
How do I make a normal display instead of XML format?
Thanks

Answer 1

It depends a good deal on the shape of the DataTable you're returning, but assuming you want the display to be something like this:
`ID Name
-------------------- ---------------------
208571635850052 Netizen Apps`
You could use LINQ:
DataTable FBWorkDt = objBLL.get_FacebookWork(FacebookUserId);
var query = from x in FBWorkDt.AsEnumerable()
select new {
id = x.ID,
name = x.Name
};
GrdWork.DataSource = query.ToList();
GrdWorkPub.DataBind();
I haven't tried the code out, so there may be minor syntatic changes, but essentially what it's doing is:
Use LINQ to get a collection of a new anonymous type that has one entry per row with the id and name from the table. You have to use AsEnumerable() [contained in System.Data.DataSetExtensions].
Convert the LINQ result set to a List via .ToList() and bind it to the GridView.
If you can post a little more information - what exactly you mean by display, and the expected shape of the returned DataTable (i.e., what the columns in each row are) we can give you a better answer.
UPDATE
If you're storing the XML document above in your datastore and that is being returned in the table, try this code:
DataTable FBWorkDt = objBLL.get_FacebookWork(FacebookUserId);
XDocument xDoc = XDocument.Load(FBWorkDt.Rows[0][0].ToString());
var query = from x in xDoc.Descendants("employer")
select new
{
id = (string)x.Element("id"),
name = (string)x.Element("name")
}
GrdWork.DataSource = query.ToList();
GrdWorkPub.DataBind();
Same basic principal as above, except this time your querying over an XDocument instead of a DataTable.
