[Solved] Set default values on new record

[JULIA]

Hello,

if i add a new line in my grid, the dropdownlist will always have the value from the first line. how can i set this value manually?
I have the following EditorTemplate

<%= Html.DropDownList( null, new SelectList( ( IEnumerable )ViewData["karnofskyEcogTypes"],
                                    "KarnofskyEcogTypeId", "LongDescription" ), new { style = "width: 90%;" } )%>

<script type="text/javascript">
    var $dropdown = $('#KarnofskyEcogType');
    $('<option/>', { text: '...', value: "" }).prependTo($dropdown);
    var $tr = $dropdown.closest('tr:has(form)');
    var grid = $tr.closest('.t-grid').data('tGrid');
    var dataItem = grid.dataItem($tr);
    $dropdown.val(dataItem.KarnofskyEcogType ? dataItem.KarnofskyEcogType.KarnofskyEcogTypeId : "");
</script>

The only way for validation ( with the RequiredAttrbiute ) is to let the value an empty string. is this the best way?

Regards,
Timo

Hi,

I believe that you need to use this SelectList constructor in order to select initial value.

Hi,

it doesn't solve the problem.
The following function is running after the click on "Add New".

$(function () {
        $(".t-grid-add").click(function () {
            alert($('.t-grid-new-row').find("#KarnofskyEcogType").length);
        });
    });

But the alert shows always 0. How can i find this DropDownList. The second click on add new (without cancel the new row) shows 1.
Is the DropDownList not inside the DOM when the click occurs?

Hello,

the problem is the code inside the EditorTemplate

<%= Html.DropDownList( null, new SelectList( ( IEnumerable )ViewData["karnofskyEcogTypes"],
                                    "KarnofskyEcogTypeId", "LongDescription" ), new { style = "width: 90%;" } )%>

<script type="text/javascript">
    var $dropdown = $('#KarnofskyEcogType');
    $('<option/>', { text: '...', value: "" }).prependTo($dropdown);
    var $tr = $dropdown.closest('tr:has(form)');
    var grid = $tr.closest('.t-grid').data('tGrid');
    var dataItem = grid.dataItem($tr);
    $dropdown.val(dataItem.KarnofskyEcogType ? dataItem.KarnofskyEcogType.KarnofskyEcogTypeId : "");
</script>

The property "dataItem.KarnofskyEcogType.KarnofskyEcogTypeId" is always set to the value from the first row. Is there a workaround or way to find out if this dataItm is inserted?
