Export Data Grid Content to an XML File

we can use the RenderControl method to extract the content into an .xml file from datagridview.
your Data Grid is not associated with any dataset.and not using any XML support functions

The following code explains:


ArrayList al = new ArrayList();
for(int i=0;i<=10;i++)
{
al.Add(i+"");
}
DataGrid1.DataSource=al;
DataGrid1.DataBind();
Response.Clear();
Response.AddHeader("content-disposition","fileattachment;filename=xmltest.xml");
Response.ContentType="text/xml";

StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
DataGrid1.RenderControl(hw);
Response.Write(sw.ToString());
Response.End();
