I have the XML given below. From this XML, in an ASPX page with an ASCX control that will contain the data, I want a drop-down on top with option ‘GMAT’, ‘GRE’, ‘LSAT’, and ‘MCAT’. And when I select GMAT below it will show only GMAT brochure and same with others.
Can you please provide some code for this?

private DataSet GenerateDatasetFromXml() { string xmlFile = string.Empty; DataSet xmlFileData = new DataSet(); string selItem = string.Empty; xmlFile = @Server.MapPath('~/' + ConfigurationManager.AppSettings['BrochureXml'].ToString()); string sfinalString = ''; hdnIds.Value = ''; try { if (File.Exists(xmlFile)) { xmlFileData.ReadXml(xmlFile); } } catch (Exception ex) { throw ex; } return xmlFileData; }
Right now, you could only select those items based on string-parsing the ImageTitle and finding substring in it – less than optimal…
If there’s any chance at all, I’d recommend adding a tag (or whatever you want to call it) to your data, something like this:
That way, selecting the proper elements would be as easy a very simple XPath expression:
once you have loaded your data file into an XmlDocument (or you the Linq-to-XML way, if you prefer that).
