How to Convert GridView To XML in ASP.Net

Hi RahulPal,

Will you please let me know how you are binding the gridview using datatable or dataset.

Or you can refer the below code to convert DataTable/DataSet to Xml.

protected void Page_Load(object sender, EventArgs e)
{
    DataTable dt = new DataTable();
    dt.Columns.Add("ID", typeof(string));
    dt.Columns.Add("Name", typeof(string));
    dt.Rows.Add("1", "A");
    dt.Rows.Add("2", "B");
    dt.Rows.Add("3", "C");

    DataSet ds = new DataSet();
    ds.Tables.Add(dt);
    // 1st method using DataSet.
    string xml = ds.GetXml();
    // 2nd method using DataTable.
    string xml1 = GenerateXML(dt);
}

public string GenerateXML(DataTable table)
{
    if (table == null)
    {
        return null;
    }
    else
    {
        using (var sw = new StringWriter())
        using (var tw = new XmlTextWriter(sw))
        {
            table.TableName = @"MyTable";
            tw.Formatting = Formatting.Indented;
            tw.WriteStartDocument();
            tw.WriteStartElement(@"data");
            ((IXmlSerializable)table).WriteXml(tw);
            tw.WriteEndElement();
            tw.WriteEndDocument();
            tw.Flush();
            tw.Close();
            sw.Flush();
            return sw.ToString();
        }
    }
}
