i not sure, want add gridview dynamically page or use 1 markup? if first, need add statement
myform.controls.add(gv); to page_load. if latter, don´t need
gridview gv = new gridview(); but can reference gv markup it´s id.
by way, have change parameter type of page_load:
protected void page_load(object sender, eventargs e)
