c# - How to set same button events for ListBox (value) index or treeview nodes? -

i have c# win-form shown below. have few array menu list-box.

public string[] arraymain = {"1.water","2.air","3.soil","4.fire"}; public string[] arraywater = {"1.salty","2.fresh", "3.contaminated"}; public string[] arraysalty = {"1.aa", "2.bb", "3.cc"}; public string[] arrayfresh = {"1.dd", "2.ee", "3.ff"}; public string[] arraycontaminated = {"1.xx", "2.yy", "3.zz"} ; public string[] arrayair = {"1.fresh", "2.contaminated"}; public string[] arraysoil = {"1.normal", "2.contaminated"}; public string[] arrayfire = {"1.low","2.mid","3.high"}; 

when application start in main list-box loaded first array values.

public form1() {     initializecomponent();     listboxmain.items.addrange(arraymain);     listview1.items.add(arraymain[0])     // user choose: 1.water } 

if user press button 1 application clears main list-box , loads selection. time list-box loaded with;

listboxmain.items.addrange(arraywater); listview1.items.add(arraymain[0]) // user choose: 1.salty 

now if user press button 2 application clears main list-box , selected menus list-box have values like;

1.water 1.salty 2.bb

then application first letter (number) fixed format like;

112

and send wfc service. wfc services know "112". major problem have set button list-box index (or combo-box say). example if user press button 1 first time user have select menus array list-box. , again if user press button 1 button 1 have connected list-box index (new values).

in previous question interesting problem user @eugene suggested me can turn logic tree-view. , stated as;

where nodes contain items combo-box (key-string show, value - value use later). when push buttons add respective node item queue , load new items. in leaf nodes contain action> call respective service method (for many options can same action)

i try apply many logic , spend 10 days make simulator works expected, failed. realy have information can set button 1 events listbox (index) or treview (nodes). if point me, how set button 1 events stated above rest easy me.

kind regards,

first time app start:

after user press buttons:

thank @eugene. made it. here is.

for main;

public form1() {     initializecomponent();      treenode tnode;     //main node 1     tnode = treeview1.nodes.add("1.water");     tnode = treeview1.nodes.add("2.air");     tnode = treeview1.nodes.add("3.soil");     tnode = treeview1.nodes.add("4.fire");      // water node     treeview1.nodes[0].nodes.add("1.salty");     treeview1.nodes[0].nodes.add("2.fresh");     treeview1.nodes[0].nodes.add("3.contaminated");      // air node     treeview1.nodes[1].nodes.add("1.fresh");     treeview1.nodes[1].nodes.add("2.contaminated");      // soil node     treeview1.nodes[2].nodes.add("1.normal");     treeview1.nodes[2].nodes.add("2.contaminated");      // fire node     treeview1.nodes[3].nodes.add("1.low");     treeview1.nodes[3].nodes.add("2.mid");     treeview1.nodes[3].nodes.add("3.high");      // salty node     treeview1.nodes[0].nodes[0].nodes.add("1.aa");     treeview1.nodes[0].nodes[0].nodes.add("2.bb");     treeview1.nodes[0].nodes[0].nodes.add("3.cc");      // fresh node     treeview1.nodes[0].nodes[1].nodes.add("1.dd");     treeview1.nodes[0].nodes[1].nodes.add("2.ee");     treeview1.nodes[0].nodes[1].nodes.add("3.ff");      // contaminated node     treeview1.nodes[0].nodes[2].nodes.add("1.xx");     treeview1.nodes[0].nodes[2].nodes.add("2.yy");     treeview1.nodes[0].nodes[2].nodes.add("3.zz");       //clear listbox items     listboxmain.items.clear();      //load listbox first time     foreach (treenode n in treeview1.nodes)     {         listboxmain.items.add(n.text);     } } 

for buttons:

// btn 1 private void btn_1_click(object sender, eventargs e) {     int value = 1 - 1;     int icount = listboxmain.items.count;      if (icount > value)     {         string item = listboxmain.items[value].tostring();         treviewnodesselection(item, value);     } }  // btn 2 private void btn_2_click(object sender, eventargs e) {     int value = 2 - 1;     int icount = listboxmain.items.count;      if (icount > value)     {         string item = listboxmain.items[value].tostring();         treviewnodesselection(item, value);     } } 

then created treviewnodesselection:

//treviewnodesselection private void treviewnodesselection(string item, int value) {     textbox1.text = item;     listboxmenu.items.add(item);       //find nodes first     traverse(treeview1.nodes, item);      //clear listbox items     listboxmain.items.clear();      //get first childnode via parenet name     if (treeview1.selectednode.nodes.count != 0)     {         foreach (treenode v in treeview1.selectednode.nodes)         {             listboxmain.items.add(v.text);         }     }     else     {         messagebox.show("now can start calculation...");     } } 

and treeview node selection

private void traverse(treenodecollection nodes, string findtext) {     foreach (treenode node in nodes)     {         if (node.text.tostring().trim() == findtext)         {             node.treeview.selectednode = node.nextnode;             treeview1.selectednode = node;             node.treeview.focus();             //messagebox.show(node.text + " selected...");         }         traverse(node.nodes, findtext);     } } 

i learn lot http://stackoverflow.com few cent contribution.
