Partial view page is

<table>
    <tr>
        <th>
            @Html.DisplayNameFor(model => model.OdrId)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.OrderNo)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.CId)
        </th>
    </tr>

@foreach (var item in Model) {
    <tr>
        <td>
            @Html.CheckBox("OdrId", new { @id="chk"})
        </td>
         <td class="left">
            @Html.DisplayFor(modelItem => item.OrderNo, new { @id="porderno"})
        </td>
        <td class="left">
            @Html.DisplayFor(modelItem => item.CId)
        </td>

    </tr>
}

</table>

And My Create View page is

@model testcon.DeliveryInfo

@{
    ViewBag.Title = "Create";
}

<h2>Create</h2>

@using (Html.BeginForm()) {
    @Html.ValidationSummary(true)

    <fieldset>
        <legend>DeliveryInfo</legend>

        @*<div class="editor-label">
            @Html.LabelFor(model => model.DId)
        </div>*@
        <div class="editor-field">
           Delivery Id : @Html.EditorFor(model => model.DId)
            @Html.ValidationMessageFor(model => model.DId)
        </div>

        @*<div class="editor-label">
            @Html.LabelFor(model => model.OrderNo)
        </div>*@
        <div class="editor-field">
          Order No :@Html.EditorFor(model => model.OrderNo)
            @Html.ValidationMessageFor(model => model.OrderNo)
            @*<a href="#" onclick="javascript:getOrderList()">Show Order</a>*@
        </div>

       @* <div class="editor-label">
            @Html.LabelFor(model => model.DDate)
        </div>*@
        <div class="editor-field">
           Delivery Date : @Html.EditorFor(model => model.DDate)
            @Html.ValidationMessageFor(model => model.DDate)
        </div>

        @*<div class="editor-label">
            @Html.LabelFor(model => model.DQuantity)
        </div>*@
        <div class="editor-field">
           Delivery Quantity: @Html.EditorFor(model => model.DQuantity)
            @Html.ValidationMessageFor(model => model.DQuantity)
        </div>

        @*<div class="editor-label">
            @Html.LabelFor(model => model.DAmount)
        </div>*@
        <div class="editor-field">
           Delivery Amount : @Html.EditorFor(model => model.DAmount)
            @Html.ValidationMessageFor(model => model.DAmount)
        </div>
        <div id="orlist" >
        </div>

        <p>
            <input type="submit" value="Create" />
        </p>
    </fieldset>
}

<div>
    @Html.ActionLink("Back to List", "Index")
</div>

Answer 1

Use .is(':checked') check if checked...

buttons: {
    Select: function() {
        if ($("#chk").is(':checked')) {
            $("#OrderNo").val($("#porderno").val());
        }
    },

Answer 2

to check if the check box is checked in jQuery , you can do it by either

//will return true if the check box is checked otherwise false!
$("#chkBoxId").is(':checked');   

or

this approach is good when dealing with group of radio buttons/checkboxes.

//will yield the same result if checkbox is checked
$('input[name="chkBoxName"]:checked').val();    

So you can use them in your code like what @ Anthony Chu has responded which i was about to write :)
