GridData();
}
}
protected void GridData()
{
string url = "http://s3.amazonaws.com/webassets.ticketmob.com/feeds/31squares/tunestub-XML.xml";
XmlDocument doc = new XmlDocument();
DataSet ds = new DataSet();
DataTable dt = new DataTable();
ds.ReadXml(url);
dt = ds.Tables[1];
grid.DataSource = ds.Tables[1];
grid.DataBind();
}
public override void VerifyRenderingInServerForm(Control control)
{
}
protected void btnExport_Click(object sender, EventArgs e)
{
Response.ClearContent();
Response.Buffer = true;
Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", "ExportVenue.xls"));
Response.ContentType = "application/ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
GridData();
for (int i = 0; i < grid.HeaderRow.Cells.Count; i++)
{
grid.HeaderRow.Cells[i].Style.Add("background-color", "#df5015");
}
grid.RenderControl(htw);
Response.Write(sw.ToString());
Response.End();
}
}
this gives me the data in xls file but i want to add a new column name "Event" & need specific column from xml like i want "name","address". how it would be possible? please help me on this...
After constructing data in data table. Add those new columns in data table like following -
DataColumn nameCol = datatable.Columns.Add("Name", typeof(string));
nameCol.AllowDBNull = false;
reference : http://msdn.microsoft.com/en-us/library/hfx3s9wd(v=vs.110).aspx and then put required data from the existing columns via for loop or existing queries.
Try to implement with this example:
Issue 1:To add new column name "Event"
string path=Application.StartupPath + @"\Test.xml";
XmlWriter writer = XmlWriter.Create(path);
XmlDocument doc = new XmlDocument();
doc.Load(path);
writer.WriteStartElement("Event");
writer.WriteString("Event Decription");
writer.WriteEndElement();
writer.WriteEndElement();
writer.WriteEndDocument();
writer.Close();
Issue 2: To get a specific column from xml
For unique column:
XmlNodeList elemnt1 = doc.GetElementsByTagName("name");
XmlNodeList elemnt2 = doc.GetElementsByTagName("address");
If there are multiple columns with same name:
XmlNodeList elem1 = doc.GetElementsByTagName("name");
for (int j = 0; j < elem1 .Count; j++)
{
if (elem1[j].InnerText == "name")
{
//want u want to do
}
}
