c# - DataGridView and Locating Data -

i using datagridview keep track of list<myobject>. populate it, use foreach loop:

foreach (myobject object in mylist) {     if (object.status == status.available)     {         mydatagridview.rows.add(object.name, object.status.tostring());     } } 

i use event create new form object in selected row:

void mydatagridview_celldoubleclick(object sender, datagridviewcelleventargs e) {     var index = mylist[mydatagridview.currentrow.index];     myform form = new myform(index); } 

so works fine until status of item in list changes:

mylist[10].status = status.unavailable; 

now when mydatagridview updated, can no longer use row index open correct form row past 10. i'm @ loss do.

can tell me how open correct form though indices don't match anymore?

edit: mylist holds characters in game, available hire , aren't. need mydatagridview populated status available.

somehow have associate index in list row. 1 way have hidden column in grid maintains mapping between row , correct list index. add hidden column, modify insert code follows:

int = 0; foreach (myobject object in mylist) {      if (object.status == status.available)      {          mydatagridview.rows.add(object.name, object.status.tostring(), i);      }       i++; }  //hide third column mydatagridview.columns[2].visible = false; 

then during celldoubleclick event can reference hidden column true index of item in row.

void mydatagridview_celldoubleclick(object sender, datagridviewcelleventargs e) {     int listindex = (int)mydatagridview.currentrow.cells[2].value;      var index = mylist[listindex];      myform form = new myform(index); }
