Hello Bas,

The Form and the Wizard components are quite new and such integration is not yet supported. The Grid has a separate implementation for rendering its popup fields that interferes with the Form component. The correct way to achieve the desired result is to first integrate the From component inside the Grid as a built-in editor and also allow for rendering the Form with custom configuration if a template is specified.

We already have a Feature Request on this functionality and I would urge you to vote on it, so it moves ahead in our priority queue:

If the requirement is to achieve ta similar look as the Form as a temporary workaround you could try to build a custom template using the Form markup classes to achieve a similar look, for example:

@model MyApp.Models.ProductViewModel

<div class="k-form">
    <fieldset class="k-form-fieldset">
        <legend class="k-form-legend">Edit Form</legend>

        <div class="k-form-field">
            @Html.LabelFor(model => model.ProductID, new { @class = "k-label" })
            <div class="k-form-field-wrap">
                @Html.TextBoxFor(model => model.ProductID, new { @class = "k-textbox" })
            </div>
        </div>

        <div class="k-form-field">
            @Html.LabelFor(model => model.ProductName, new { @class = "k-label" })
            <div class="k-form-field-wrap">
                @Html.TextBoxFor(model => model.ProductName, new { @class = "k-textbox" })
            </div>
        </div>
    </fieldset>
</div>
