types - Get value of CheckBox in GridView, Bit Datatype, asp.net -

-

  1. i beginner , question or syntax may silly.
  2. i have drawn grid view having based on sqldatasource query.
  3. converted status field bit.
  4. a checkbox automatically created.

now how can value of checkbox on selectedindexchanged.

        protected void gridview1_selectedindexchanged(object sender, eventargs e)     {         panel_entry.visible = true;         int = gridview1.selectedindex;         string vdescr = gridview1.rows[i].cells[2].text;         checkbox chk = (checkbox)gridview1.rows[i].findcontrol("bitstatus");         response.write(chk.tostring()+vdescr);}

system.nullreferenceexception: object reference not set instance of object.

error shown. please in regard.

when add control dynamically , should load control again , not list in control tree.for finding can use loop find said in post better way find control in asp.net

also @ post too: seems useful asp.net findcontrol not working - how come?
