dataset to XML not passing column values

Question

I have a sqldatasource that shows in a grid view. So basically what I did was took the gridview and made it to a dataset to export to a XML file. The issue is the XML file is being created (when pressing the report button I have in the aspx page) with the columns in it but that values of the columns are not showing. Can anyone help me with this issue?

bellow is the XML file being generated when pressing the report button(Sample2.xml):

<?xml version="1.0" standalone="yes"?>
<xs:schema id="NewDataSet" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">
  <xs:element name="NewDataSet" msdata:IsDataSet="true" msdata:UseCurrentLocale="true">
    <xs:complexType>
      <xs:choice minOccurs="0" maxOccurs="unbounded">
        <xs:element name="DefaultView" msdata:CaseSensitive="False" msdata:Locale="en-US">
          <xs:complexType>
            <xs:sequence>
              <xs:element name="USERID" type="xs:int" minOccurs="0" />
              <xs:element name="NAME" type="xs:string" minOccurs="0" />
              <xs:element name="TITLE" type="xs:string" minOccurs="0" />
              <xs:element name="CHECKTIME" type="xs:dateTime" minOccurs="0" />
              <xs:element name="CHECKTYPE" type="xs:string" minOccurs="0" />
              <xs:element name="trans" type="xs:int" minOccurs="0" />
            </xs:sequence>
          </xs:complexType>
        </xs:element>
      </xs:choice>
    </xs:complexType>
  </xs:element>
</xs:schema>

            DataTable table = view.ToTable();        
            DataSet ds = new DataSet();


            ds.Tables.Add(table);
            ds.WriteXmlSchema("Sample2.xml");

        }


    }

Answer 1

Problem:

You are using WriteXmlSchema which returns only schema of the DataSet .

Solution:

Change it to WriteXml and you will get the values of the DataSet .

ds.WriteXml("D:\\Sample2.xml");
