I have the following XML data. I need to present them on ASP.NET web page in a hierarchical tabular format.
XML:
<Developers>
<Region name="UK">
<Region name="England">
<Region name="London">
<Data Date="01-01-2019">
<Value name="DotNet">100</Value>
</Data>
<Data Date="01-01-2020">
<Value name="DotNet">200</Value>
<Value name="Java">300</Value>
</Data>
</Region>
<Region name="Other">
<Data Date="01-01-2019">
<Value name="DotNet">400</Value>
</Data>
<Data Date="01-06-2019">
<Value name="DotNet">500</Value>
</Data>
</Region>
</Region>
<Region name="Scotland">
<Data Date="01-01-2019">
<Value name="DotNet">600</Value>
</Data>
</Region>
</Region>
<Region name="France">
<Data Date="01-06-2020">

</Data>
</Region>
<Region name="Germany">

</Data>
</Region>

Expected Output:
where (-) is tree view's expand/collapse control.
Is it possible to achieve this using ASP.NET Data Grid? Any code example would be really useful.

namespace ASPNetCookbook.CSExamples
{
public class CH01DataGridWithXMLCS : System.Web.UI.Page
{
private void Page_Load(object sender, System.EventArgs e)
{
const String Region_TABLE = "Region";
DataSet dSet = null;
String xmlFilename = null;
if (!Page.IsPostBack)
{
try
{
// get fully qualified path to the "Region" xml document located
xmlFilename = Server.MapPath("xml") + "\\Region.xml";
dSet = new DataSet( );
dSet.ReadXml(xmlFilename);
// bind the dataset to the datagrid
dgRegion.DataSource = dSet.Tables[Region_TABLE];
dgRegion.DataBind( );
}
finally
{
// cleanup
if (dSet != null)
{
dSet.Dispose( );
}
} // finally
}
} // Page_Load
}
