i want to show empty rows in the gridview, That also based on the page size of the grid view. If page size=20 means and grid contain only 15 records means then i want to show 5 empty rows in the gridview (or) page size=10 then i have 15 records means then i want to insert 5 empty rows in the 2nd page of the grid. This is my requirment.....

For adding blank row in your grid view you need to add that row to your data source before you attach your data source to your grid...

like this...

if you use data set or data table as your data source then after fetching data from your data base then fill your data table or data set..
then check for the record count from your data table or data set..

now if it will return 15 record counted then fire one loop and add new row to that table...

protected void FillBlankRowToGrid()
{  
    //here your code to fill your data table with data base records.....
    //if it will return 15 records then this loop will fill 5 black row to your grid
    DataRow dr;
    for (int i = dt.Rows.Count; i < 20; i++)
    {
        dr = dt.NewRow();
        dr[0] = dr[1] = dr[2] = dr[3] = dr[4] = "";
        dt.Rows.Add(dr);
    }
    dt.AcceptChanges();
    grdView.DataSource = dt;
    grdView.DataBind();
}
