Hi,
I am working in silverlight and i have one Grid with many Rows.

Now i want to print this Grid with all row.
I found many solution for PrintDocument in Silverlight but it print only first page multiple time.
 
My code is like,

void btnPrint_Click(object sender, RoutedEventArgs e)
{
    PrintDocument pd = new PrintDocument();
    pd.PrintPage += new EventHandler(pd_PrintPage);
    pages.Add(grdMain); pd.Print("Title1");
}
void pd_PrintPage(object sender,PrintPageEventArgs e)
{
    e.PageVisual = grdMain; e.HasMorePages = true;
}   

When i add e.HasMorePages = true that time it will going to infinite loop and does not print.
