XML binding

[Alex]

We are using the RAD chart and love it.  We are having a problem displaying XML data in non file format.  If we save the XML file the chart populates correctly, if we try using an object, we get :

 

“There is no or empty series”

Here is our code, any help would be appreciated:

We have to bind RadChart.

…..

Dim resp As HttpWebResponse = DirectCast(req.GetResponse(), HttpWebResponse)

Dim reader As New StreamReader(resp.GetResponseStream())

Dim d As New XmlDocument()

d.LoadXml(reader.ReadToEnd())

reader.Close()

d.Save(Server.MapPath("xmlFiles/Expense.xml"))

RadChart1.DataSource = Server.MapPath("~/xmlFiles/Expense.xml")

RadChart1.DataBind()

 

This is works, but if I try to bind without save xml file (d.Save(Server.MapPath("xmlFiles/Expense.xml"))) :

…..

Dim resp As HttpWebResponse = DirectCast(req.GetResponse(), HttpWebResponse)

Dim reader As New StreamReader(resp.GetResponseStream())

Dim d As New XmlDocument()

d.LoadXml(reader.ReadToEnd())

reader.Close()

RadChart1.DataSource = d.OuterXml

RadChart1.DataBind()

Hi Alex,
In this case, you can use an XMLDataSource control. For example:

XmlDataSource1.Data = d.OuterXml

RadChart1.DataSourceID = XmlDataSource1.ID
RadChart1.DataBind()

For additional information on binding to XML using an XMLDataSource, please refer to our online documentation - http://www.telerik.com/help/aspnet-ajax/radchart-building-bind-xml-data-source-design-time.html.
