i have the xml below. it is being generated by a select that joins a couple tables (see the select here)

      SELECT      pm.ProjectMilestoneId,
                  pm.ProjectId,
                  pm.MilestoneCID,
                  pm1sc.CodeName as MilestoneText,        
                  pm.StartDate,        
                  pm.EndDate,        
                  pm.RAGStatusCID,        
                  pm2sc.CodeName as RAGStatusText,        
                  pm.CompletionStatusCID,        
                  pm3sc.CodeName as CompletionStatusText,        
                  pm.StatusText,        
                  pm.ReportingPriority,        
                  pm.Added,        
                  pm.LastUpdate,        
                  pm.UpdateBy  
      FROM ProjectMilestone pm  
                  INNER JOIN StatusCode pm1sc ON pm.MilestoneCID = pm1sc.CID  
                  INNER JOIN StatusCode pm2sc ON pm.RAGStatusCID = pm2sc.CID  
                  INNER JOIN StatusCode pm3sc ON pm.CompletionStatusCID = pm3sc.CID  
      WHERE pm.ProjectId = @ProjectId  
      ORDER by pm.StartDate desc
      for xml auto

the xml for this sql is below. and causes my C# data bind to fail. my c# code is as follows:

System.Xml.XmlReader xr = cmd.ExecuteXmlReader();
            DataSet ds2 = new DataSet();
            ds2.ReadXml(xr, XmlReadMode.InferSchema);
           
            DataView myDataView = new DataView();
            myDataView = ds2.Tables[0].DefaultView;

            gvMilestone.DataSource = myDataView;
            gvMilestone.DataBind();

What is the error you are seeing?

btw. you don't need the "new DataView()" line as this new object is being removed in the following line.

Change to:

DataView myDataView = ds2.Tables[0].DefaultView;

A field or property with the name 'MilestoneText' was not found on the selected data source

seems like the tables that get joined produces sub nodes in the xml instead of tossing all the values in the select into a single xml node as attributes. i think having this would solve the problem.

Yes that is probably true.

If you infer the schema than everything will be a node as the xml parser has no idea what should/shouldn't be an attribute.

If you know what the schema is why don't you explicitly create it first?

guys its simpler than that.
instead of for xml auto (creating new nodes)
i used for xml raw (creates all fields as attributes to a single noe)

and it works fine

Do you pre-define any columns in your grid?

I think generaly the dataset column names that are generated look like "Milestone_Text"

try removing all pre-define columns and allow auto-generate columns
