c# - Multiple Parameters in GridView with multiple DataKeyNames passing same value for all parameters -

-

i have gridview1 want populate gridview2

gridview1 declared so:

<asp:gridview runat="server" id="gwdup" allowpaging="true" allowsorting="true" pagesize="15" datakeynames="caseid, column2, adate, adddate"     autogeneratecolumns="false" datasourceid="sqldatasource1"` >  <asp:commandfield showselectbutton="true" />      <asp:boundfield datafield="column1" headertext="possible duplicates" readonly="true"          sortexpression="column1" />     <asp:boundfield datafield="caseid" headertext="caseid"          sortexpression="caseid" />     <asp:boundfield datafield="column2" headertext="column2"            sortexpression="column2" />     <asp:boundfield datafield="adate" headertext="adate" sortexpression="adate" />     <asp:boundfield datafield="adddate" headertext="adddate"          sortexpression="adddate" /> </columns> </asp:gridview>

i've put in function check values being passed in when click on select:

protected void sqldatasource2_selecting(object sender, sqldatasourceselectingeventargs e)     {         foreach (controlparameter s in sqldatasource2.selectparameters)         {             response.write(s.tostring());         }     }

(i using debugger value, not response.write...)

though seems parameter name changes should, value same (of caseid, first parameter) doing wrong here? how come same value gets passed in 4 parameters?

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
