dropdownlist item selected throw exception (stack empty)

dropdownlist item selected throw exception (stack empty)

Content Index :

should help you out The "Stack Empty" error is caused by a Visual Studio design time feature I think. Probably not relevant.
The error message says it all. The drop down already has a different item (other than 1990) selected, and you are trying to select 1990 as well.
ddl_y.Items.FindByValue(result.Birthday.Value.Year.ToString()).).Selected = true;

To fix this issue You are correct. The C++ standard always prefers performance to safety. But there may be STL implementations that include debug range checks.

I wish this helpful for you You can use javascript to enable or disable the dropdown on change of the checkbox. To track the checkbox and corresponding dropdown, make the html id of dropdown as
<%=f.select :dropdown1, options, :html=>{:disabled=>true, :id => "dropdwon_#{group_id}"} %>

it helps some times You can just add the onchange attribute like you have done with the id attribute in your HTML helper:
<%:Html.Label("Poste :")%><%: Html.DropDownListFor(model => model.SelectedPoste, Model.PostesItems, new { @id = "poste", onchange = "test3()" })%>

<%:Html.Label("Poste Suivant :")%><%: Html.DropDownListFor(model => model.PosteSuivantSelected, Model.NextPS, new { @id = "dd" })%>
<body onload="test3()">
var removedOption = null;
var removedOptionIndex = -1;

function test3() {
    var dd = document.getElementById('dd');
    var posteElement = document.getElementById('poste');
    var currentValue = posteElement.options[posteElement.selectedIndex].value; // this will be the value of the selected option, '2' in this case: <option value="2">Two</option>
    var currentText = posteElement.options[posteElement.selectedIndex].text; // this will be the text of the selected option, 'Two' in this case: <option value="2">Two</option>

    // add the previously removed option back into the list in its previous position
    if (removedOption != null) {
        var newOpt = document.createElement("option");
        newOpt.value = removedOption.value;
        newOpt.innerHTML = removedOption.text;
        if (removedOptionIndex < 0) removedOptionIndex = 0;
        if (removedOptionIndex > dd.options.length) removedOptionIndex = dd.options.length;
        insertOptionToSelect(dd, removedOptionIndex, newOpt);
        removedOption = null;

    for (var i = 0; i < dd.options.length; i++) // loop through all of dd's options
        if (dd.options[i].value == currentValue) // use this if you want to compare by value
            removedOption = dd.options[i];
            removedOptionIndex = i;
        if (dd.options[i].text == currentText) // use this if you want to compare by text
            removedOption = dd.options[i];
            removedOptionIndex = i;

function insertOptionToSelect(select, idx, option) {
    var saved = [];
    var i;
    for (i = 0; i < select.options.length; i++) {
    select.options.length = 0;
    for (i = 0; i < idx; i++) {
        select.options[select.options.length] = saved[i];
    select.options[select.options.length] = option;
    while (i < saved.length) {
        select.options[select.options.length] = saved[i++];
