如果在c＃中gridview中的行，我如何计算总数？

Question

我有一个页面大小为5的网格视图。 gridview包含30行。当我将它导出到excel时，它只显示5行。如何在gridview中显示Excel工作表中的所有行？不是表，因为gridview包含rowdatabound事件的行。

for (int j = 0; j < gvvessel.Rows.Count; j++)
{
Label lblvess = (Label)gvvessel.Rows[j].FindControl("lblvesselName");
string myVal = lblvess.Text;
Label lblShipEmail = (Label)gvvessel.Rows[j].FindControl("lblShipEmailID");
string mylblShipEmail = lblShipEmail.Text;
Label lblAllowTo = (Label)gvvessel.Rows[j].FindControl("lblAllowToken");
string mylblAllowTo = lblAllowTo.Text;
Label lblAssignToken = (Label)gvvessel.Rows[j].FindControl("lblAssignToken");
string mylAssignToken = lblAssignToken.Text;
Label lblRemainingT = (Label)gvvessel.Rows[j].FindControl("lblRemainingToken");
string mylRemainingT = lblRemainingT.Text;
Label lblpkg = (Label)gvvessel.Rows[j].FindControl("lblpackagedate");
string myVal1 = lblpkg.Text;
Label lbllastupd = (Label)gvvessel.Rows[j].FindControl("lbllastupdate");
string myVal2 = lbllastupd.Text;

}
