关于jQuery UI对话框 [英] About the jQuery UI dialog

问题描述

如何在对话框（jQuery UI）中执行CRUD操作（实体框架）和在我的MVC应用程序中进行流程验证？



我的问题与jQuery有关，特别是关于如何显示对话框然后处理来自Controller的响应/数据验证。



我在Index.vbhtml中有这个代码：

How to perform CRUD operations (Entity Framework) in dialogues (jQuery UI) and process validation in my MVC application ?

My problem is related to jQuery, specifically on how to show the dialog then treat the responses/data validations from the Controller.

I have this code in Index.vbhtml:

@ModelType UsuariosModel

@Code
    ViewData("Title") = "GradeUsuarios"
    Dim grid As New WebGrid(Model.Usuarios, rowsPerPage:=3, canPage:=True, canSort:=True)
End Code

@Using Html.BeginForm()

    @<div class="fluid responsive-pnl">
        <div class="child">
            <h2><b>Usuários</b></h2>
        </div>
        <div class="separator"></div>
        <div class="child">
            <b>Mostrar usuários:</b><br />
            @Html.DropDownListFor(Function(m) m.RegraMaster, New SelectList(Model.Regras))
        </div>
        <div class="child">
            <button type="submit" title="Filtrar">
                <img src="~/Images/FilterAdd.png" alt="" style="border:none;width:24px;" />
            </button>
        </div>
        <div class="separator"></div>
        <div class="child">
            <a href="#" title="Novo registro...">
                <img src="../../Images/EditAdd.png" alt="" style="border:none;width:24px;" onclick="Criar()" />
            </a>
        </div>
        <div class="separator"></div>
    </div>

    @grid.GetHtml(
                tableStyle:="table table-responsive tabela",
                mode:=WebGridPagerModes.All,
                caption:="Usuários",
                columns:=grid.Columns(
                grid.Column("ProviderUserKey", "Id"),
                grid.Column("UserName", "Usuário"),
                grid.Column("CreationDate", "Criação"),

在控制器上我有这个代码：

To create, edit or delete a record, the jQuery UI dialog is shown with a model.
The dialog sends the model to the controller at end of edition.

When saving, if the model state (in controller) is not valid, the controller returns a partial view.

This partial view works, but no more inside the dialog.



It seams that I need to treat the response from controller and re-create the dialog if the response is invalid, in my jQuery script, but I don’t know how to do it.



Thank you all again!
