c# - Combo Box Data Binding -

-

hopefully has seen before , can see mistake:

i binding combo box selected value data set , first time change combo box selected value, not update in data set i.e. values don't match. if change selected value second time works expected , data set updates match combo box.

i using second data set data source populates list of items text (for user) provides index save in first data set.

combobox.databindings.add(new system.windows.forms.binding("selectedvalue", dataview1, "mode", true)); combobox.datasource = dataview2; combobox.displaymember = "list_str.str_text"; combobox.valuemember = "list_str.index";

any idea why data set not update first time selected value changes?

edit: may not have been clear i'm not binding directly data set - using data view since have multiple tables in data set. possible use data view automatically save data set? should close , open new question?

try combobox.selectedindexchanged instead.

selectedindexchanged * raised when datasource set * raised when selectedindex set programmatically

selectionchangecommitted * not raised when datasource set * not raised when selectedindex set programmatically

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
