我有一个问题，而从电网到excel.I显示数据已经实现分页，问题是显示只出口到Excel中并不是所有的页面的页面。
你可能会考虑创建一个网格显示数据的第二页，但是与页面关闭。这样，所有的数据将被导出到Excel
如果从数据库读取的所有记录，并将其存储在本地，那么你可以考虑将数据从源出口。不从DataGrid分页实现它包含的页面大小的记录。
//导出实际数据集
if (rds != null && rds.Tables.Count != 0)
{
#region WriteToTheStringBuilder
DataTable dt = rds.Tables[0];
StringBuilder str = new StringBuilder ();
//first add the column names
for (int j = 0; j <= dt.Columns.Count - 1; j++)
{
//comm -- remove only one tab if exists from each cell
str.Append ( dt.Columns[j].ToString () + "\t" );
}
str.AppendLine();
//comm -- than add by row the whole table
for (int i = 0; i <= dt.Rows.Count - 1; i++)
{
for (int j = 0; j <= dt.Columns.Count - 1; j++)
{
//comm -- remove only one tab if exists from each cell
str.Append ( Utils.Str.Str.FindAndReplace (
dt.Rows[i][j].ToString (), "(.*)(\t)(.*)", "$1$3" ) + "\t" );
}
str.AppendLine();
}
