grid view printing with table in asp.net

Solution 1
Create a Data Adapter, create a Command Object with a Select query, set the adapter's command to this command object, issue an adapter.fill(dataset), set the data source of gridview as the dataset and databind the GridView.
For code, a simple Google search will work. You did not even specify a language. I guess you are working in C# and this is your college project. Is it?

maybe this can help.
public class GridViewExportUtil {
public static void Export(string fileName, GridView gv)
{
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.ClearHeaders();
HttpContext.Current.Response.ClearContent();
HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding("windows-1254");
HttpContext.Current.Response.Charset = "windows-1254"; //ISO-8859-13 ISO-8859-9 windows-1254
HttpContext.Current.Response.AddHeader(
"content-disposition", string.Format("attachment; filename={0}", fileName));
HttpContext.Current.Response.ContentType = "application/ms-excel";
string header = "<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\">\n<html xmlns=\"http://www.w3.org/1999/xhtml\">\n<head>\n<title></title>\n<meta http-equiv=\"Content-Type\" content=\"text/html; charset=windows-1254\" />\n<style>\n</style>\n</head>\n<body>\n";
using (StringWriter sw = new StringWriter())
{
using (HtmlTextWriter htw = new HtmlTextWriter(sw))
{
// Create a form to contain the grid
Table table = new Table();
table.GridLines = GridLines.Horizontal;
//table.CellSpacing = 17;
// add the header row to the table
if (gv.HeaderRow != null)
{
GridViewExportUtil.PrepareControlForExport(gv.HeaderRow);
table.Rows.Add(gv.HeaderRow);
}
// add each of the data rows to the table
foreach (GridViewRow row in gv.Rows)
{
GridViewExportUtil.PrepareControlForExport(row);
table.Rows.Add(row);
}
// add the footer row to the table
if (gv.FooterRow != null)
{
GridViewExportUtil.PrepareControlForExport(gv.FooterRow);
table.Rows.Add(gv.FooterRow);
//table.Height = 17;
}
// render the table into the htmlwriter
table.RenderControl(htw);
// render the htmlwriter into the response
HttpContext.Current.Response.Write(header + sw.ToString());
HttpContext.Current.Response.End();
}
}
}

First, get your data displaying in the GridView (there are about a bazillion resources on this site and other to show you how to do that).
Here's the javascript to print the window:
<INPUT TYPE="button" onClick="window.print()">
