c# - How to make a specific Tree Node to appear as a folder in a Tree View -

-

how make specific tree node appear folder in tree view? creating dynamic tree view using table in database , based on 1 column i.e., nodetype having value (1 or 2), want either appear folder or normal tree node.

pseudo code more beneficial.

desired result

thanks in advance!

you can put folder image in imagelist control , set imagelist property of treeview control imagelist , when creating nodes set imageindex of node desired index.

    treenode tn = new treenode();     if (imageshouldbefolderimage)         tn.imageindex = 0;      // if want show image other cases,      // if want no image ignore else part     else                     tn.imageindex = 1;

update:

if selecting node changes it's image undesirable image it's caused treeview's selectedimageindex property, suggest adding empty image imagelist , set nodes selectedimageindex.

treenode tn = new treenode(); if (imageshouldbefolderimage) {     tn.imageindex = 0;     tn.selectedimageindex = 0; } else {                 tn.imageindex = 1;//the index of empty image     tn.selectedimageindex = 1; }

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...
