If you have paging then the gridview only holds the data that is visible, ie the current page, you can't get other rows. If you can access data outside the current page depends on what data you are getting and how you are doing your paging. If you get all the data then bind the gridview to a single page of that data then you can access all the rows from the data that you bound the gridview from. If you only get the current page from your datasource and that is what is shown in the gridview then you simply can't get at data outside the current page as you have never retrieved it. To access the data you'll need to retrieve it from wherever it is kept.

protected void btnDisplay_Click(object sender, EventArgs e)
{
gvProducts.AllowPaging = false;
gvProducts.DataBind();
int rowCount = Convert.ToInt32(tbxRowCount.Text);
GridViewRow row = null;
for (int index = 0; index < rowCount; index++)
{
row = gvProducts.Rows[index];
Label lblProductName = (Label)row.FindControl("lblProductName");
Label lblProductNumber = (Label)row.FindControl("lblProductNumber");
Label lblProductPrice = (Label)row.FindControl("lblProductPrice");
AddRow(lblProductName.Text, lblProductNumber.Text,
lblProductPrice.Text);
}
gvProducts.AllowPaging = true;
gvProducts.DataBind();
}
private void AddRow(string productName, string productNumber, string price)
{
HtmlTableRow row = new HtmlTableRow();
HtmlTableCell productNameCell = new HtmlTableCell();
HtmlTableCell productNumberCell = new HtmlTableCell();
HtmlTableCell productPriceCell = new HtmlTableCell();
productNameCell.InnerText = productName;
productNumberCell.InnerText = productNumber;
productPriceCell.InnerText = String.Format("{0:C}", price);
row.Cells.Add(productNameCell);
row.Cells.Add(productNumberCell);
row.Cells.Add(productPriceCell);
tblProducts.Rows.Add(row);
}
