Binding a datepicker to dynamically generated textboxes

I have several textbox elements being generated in a foreach, like this:

@foreach(var thing in Model.Things)
{
    <tr>
        <td>@Html.TextBoxFor(m => thing.StartDate, new { id = "thingStartDate", @class = "thingDatePicker" })</td>
    </tr>
}

I'm attaching jQuery datepickers to each textbox, like this:

$(document).ready(function(){
    $(".thingDatePicker").datepicker({ dateFormat: "mm/dd/yy" });
});

The datepickers all fire correctly on each textbox, in the correct positions. But when I select a date from any of them, it only populates the first textbox. How do I make sure each datepicker is firmly associated with its textbox?

You seem to be using the same id for all your textboxes (id="thingStartDate") which obviously results in invalid HTML. So either remove the id attribute or make sure you don't get dupes. I would probably remove it as you are using a class selector and this id serves no purpose at all:

@foreach(var thing in Model.Things)
{
    <tr>
        <td>
            @Html.TextBoxFor(
                m => thing.StartDate, 
                new { @class = "thingDatePicker" }
            )
        </td>
    </tr>
}

Also I hope you realize that m => thing.StartDate will generate incorrect names for those textboxes. It will use name="StartDate" instead of name="Things[xxx].StartDate" which might get you into troubles later when you attempt to bind back to your view model. For this purpose I recommend scraping the foreach loops in view in favor of editor/display templates:

@Html.editorFor(x => x.Things)

and inside the corresponding editor template (~/Views/Shared/EditorTemplates/Thing.cshtml)

@model Thing
<tr>
    <td>
        @Html.TextBoxFor(
            x => x.StartDate, 
            new { @class = "thingDatePicker" }
        )
    </td>
</tr>
