[Solved] Disabled DropDownList column - Behavior Change in 2011 Q2

[Leo]

Telerik,

  I have an MVC Grid with a special requirement: Allow to insert rows, but only allow certain fields to be updated. I was achieving this by manually disabling specific DropDownLists using onGridEdit client-side event... After updating to 2011.2.712.340 I notice that the disabled field values are no longer included in the form post values...

 Is this the expected behavior? Is there a workaround I could try to accomplish this?

Thanks,
Leo.

I was using server edit mode, I had same requirement, the following are my solution for your reference:

Add an editor template file for editable object:

@model WorkflowAction

<table>
<tr>
    <td>@Html.LabelFor(model => model.ActionName)</td>
    <td>@Html.EditorFor(model => model.ActionName) @Html.ValidationMessageFor(model => model.ActionName)</td>
</tr>
<tr>
    <td>@Html.LabelFor(model => model.ActionDesc)</td>
    <td>@Html.EditorFor(model => model.ActionDesc) @Html.ValidationMessageFor(model => model.ActionDesc)</td>
</tr>
@if (Request.QueryString["Grid-mode"].ToLower() == "insert")
{
<tr>
    <td>@Html.LabelFor(model => model.WorkflowTypeId)</td>
    <td>@Html.EditorFor(model => model.WorkflowTypeId) @Html.ValidationMessageFor(model => model.WorkflowTypeId)</td>
</tr>
<tr>
    <td>@Html.LabelFor(model => model.OldStatus)</td>
    <td>@Html.EditorFor(model => model.OldStatus) @Html.ValidationMessageFor(model => model.OldStatus)</td>
</tr>
<tr>
    <td>@Html.LabelFor(model => model.NewStatus)</td>
    <td>@Html.EditorFor(model => model.NewStatus) @Html.ValidationMessageFor(model => model.NewStatus)</td>
</tr>
}
else
{
  // You can place hidden object here for post back.
  // @Html.HiddenFor(......)
}
<tr>
    <td>@Html.LabelFor(model => model.IsNotifiable)</td>
    <td>@Html.EditorFor(model => model.IsNotifiable) @Html.ValidationMessageFor(model => model.IsNotifiable)</td>
</tr>
<tr>
    <td>@Html.LabelFor(model => model.IsAvailable)</td>
    <td>@Html.EditorFor(model => model.IsAvailable) @Html.ValidationMessageFor(model => model.IsAvailable)</td>
</tr>
<tr>
    <td style="width:200px"> </td>
    <td> </td>
</tr>
</table>

Hello,

Disabled form elements do not submit their values, so for Q2 2011 we changed the behavior of some of our components to match this, as mentioned in the release notes.

The workaround in this case depends on the developer's preferences - for example the component can be hidden with Javascript, but not disabled.
