将参数传递给telerik asp.net mvc网格

Question

我有一个telerik asp.net mvc网格,需要根据用户在单独的文本框中输入的搜索条件进行填充.网格最初使用ajax方法加载自身以及进行分页.

如何将搜索参数传递给网格,以便它"每次"调用ajax方法发送这些参数,以响应用户点击另一个页面转到该页面上的数据？

我阅读了telerik的用户指南,但没有提到这种情况.我上面能做的唯一方法是使用jquery将参数传递给客户端的rebind()方法.问题是我不确定它是否是传递参数的"官方"方式,即使在更新后也始终有效.我在telerik的网站上发现了这个方法:链接文本

我必须传递多个参数.当telerik网格调用时,控制器中的操作方法会根据搜索参数再次运行查询.

这是我的代码片段:

$("#searchButton").click(function() {
    var grid = $("#Invoices").data('tGrid');

    var startSearchDate = $("#StartDatePicker-input").val();
    var endSearchDate = $("#EndDatePicker-input").val();

    grid.rebind({ startSearchDate: startSearchDate ,
                    endSearchDate: endSearchDate
                });
});

Answer 1

因此根据Telerik的说法,"推荐的方法是在onDataBinding事件中设置参数".

function onGridBinding(e) {
if (cancelGridBinding) {  
    // ...
}
else {
    var searchValue = 'something';
    e.data = { search: searchValue };
}

}

Answer 2

对于我自己,我使用我使用jQuery和javascript对象传递的ViewModel对象,我的View是强大的类型SearchMemberModel,包含我的搜索字段,我的视图中的每个字段都有一个Textbox.我的数据绑定是将Model传递给控制器​​.然后我用javascript构建我的对象,并在重新调用调用中将它传递给我的控制器.

这是我的代码:

查看和javascrip

<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Admin.Master" Inherits="System.Web.Mvc.ViewPage<Enquete.Models.SearchMemberModel>" %>

<% using (Html.BeginForm()) {%>
    <%: Html.ValidationSummary(true) %>

    <fieldset>
        <legend><%: Resources.Search %></legend>

        <div class="editor-label">
            <%: Html.LabelFor(model => model.MemberNumber) %>
        </div>
        <div class="editor-field">
            <%: Html.TextBoxFor(model => model.MemberNumber) %>
            <%: Html.ValidationMessageFor(model => model.MemberNumber) %>
        </div>

        <div class="editor-label">
            <%: Html.LabelFor(model => model.Email) %>
        </div>
        <div class="editor-field">
            <%: Html.TextBoxFor(model => model.Email) %>
            <%: Html.ValidationMessageFor(model => model.Email) %>
        </div>

        <div class="editor-label">
            <%: Html.LabelFor(model => model.FirstName) %>
        </div>
        <div class="editor-field">

            <%: Html.ValidationMessageFor(model => model.FirstName) %>
        </div>

        <div class="editor-label">
            <%: Html.LabelFor(model => model.LastName) %>
        </div>
        <div class="editor-field">
            <%: Html.TextBoxFor(model => model.LastName) %>
            <%: Html.ValidationMessageFor(model => model.LastName) %>
        </div>

        <div class="editor-label">
            <%: Html.LabelFor(model => model.Phone) %>
        </div>
        <div class="editor-field">

            <%: Html.ValidationMessageFor(model => model.Phone) %>

        <div class="editor-label">
            <%: Html.LabelFor(model => model.Active) %>
        </div>
        <div class="editor-field">
            <%: Html.CheckBoxFor(model => model.Active) %>
            <%: Html.ValidationMessageFor(model => model.Active) %>
        </div>

        <p>
            <input type="submit" value="<%: Resources.ToSearch %>" id="btnSearch" />
        </p>
    </fieldset>

<% } %>

 <%= Html.Telerik().Grid<SerializableMember>()
                .Name("Grid")
                .Columns(colums =>
                 {
                     colums.Bound(c => c.Email).Title(Resources.Email);//.ClientTemplate("<a href=\"" + Url.Action(MVC.Admin.Edit()) + "/<#=Id#>\" ><#=Email#></a>");
                     colums.Bound(c => c.FirstName).Title(Resources.FirstName);
                     colums.Bound(c => c.LastName).Title(Resources.LastName);
                     colums.Bound(c => c.MemberNumber).Title(Resources.MemberNumber);
                     colums.Bound(c => c.Active).Title(Resources.Active).HeaderHtmlAttributes(new { @class = "center-text" }).HtmlAttributes(new { @class = "center-text" }).ClientTemplate("<img src=\"Content/images/icons/<#=Active#>.png\" alt=\"<#=Active#>\" />");
                     colums.Bound(c => c.Id).Title(" ").HtmlAttributes(new { @class = "center-text" }).ClientTemplate("<a href=\"" + Url.Action(MVC.Member.ResetPassword()) + "/<#=Id#>\" title=\"" + Resources.ResetPassword + "\" >" + Resources.ResetPassword + "</a>");
                     colums.Bound(c => c.Id).Title(" ").HtmlAttributes(new { @class = "center-text" }).ClientTemplate("<a href=\"" + Url.Action(MVC.Member.Activate()) + "/<#=Id#>\" title=\"" + Resources.Activate + "\" >" + Resources.Activate + "</a>");
                     colums.Bound(c => c.Id).Title(" ").HtmlAttributes(new { @class = "center-text" }).ClientTemplate("<a href=\"" + Url.Action(MVC.Member.Deactivate()) + "/<#=Id#>\" title=\"" + Resources.Deactivate + "\" >" + Resources.Deactivate + "</a>");
                 })
                //.DataBinding(d => d.Ajax().Select("ListAjax", "Member", Model))
                .DataBinding(d => d.Ajax().Select(MVC.Member.ListAjax(Model).GetRouteValueDictionary()))
                .Sortable()
                .NoRecordsTemplate(Resources.NoData)
        %>
        <%= Html.AntiForgeryToken() %>

        <script type="text/javascript">
            $(document).ready(function () {
                $('#btnSearch').click(function () {
                    var grid = $('#Grid').data('tGrid');
                    var searchModel = {
                        MemberNumber: $('#MemberNumber').val(),
                        Email: $('#Email').val(),
                        FirstName: $('#FirstName').val(),
                        LastName: $('#LastName').val(),
                        Phone: $('#Phone').val(),
                        Active: $('#Active').is(':checked')
                    };
                    grid.rebind(searchModel);
                    return false;
                });
            });
        </script>

        <%= Html.Telerik().ScriptRegistrar().jQuery(false).DefaultGroup(g => g.DefaultPath("~/Content/Javascript/2010.3.1110"))%>

那是我的掌控者

[GridAction]
    public virtual ActionResult ListAjax(SearchMemberModel search)
    {
        var gridModel = new GridModel<SerializableMember>();
        var data = _session.All<Member>();
        if (search != null)
        {
            if (search.Active) data = data.Where(x => x.Active);
            if (!string.IsNullOrEmpty(search.Email)) data = data.Where(x => x.Email.Contains(search.Email));
            if (!string.IsNullOrEmpty(search.FirstName)) data = data.Where(x => x.FirstName.Contains(search.FirstName));
            if (!string.IsNullOrEmpty(search.LastName)) data = data.Where(x => x.LastName.Contains(search.LastName));
            if (!string.IsNullOrEmpty(search.MemberNumber)) data = data.Where(x => x.MemberNumber.Contains(search.MemberNumber));
            if (!string.IsNullOrEmpty(search.Phone)) data = data.Where(x => x.Phone.Contains(search.Phone));
        }

        var list = new List<SerializableMember>(data.Count());
        list.AddRange(data.ToList().Select(obj => new SerializableMember(obj)));
        gridModel.Data = list;
        return View(gridModel);
    }

我也可以给你我的搜索模型类:

public class SearchMemberModel
{
    [LocalizedDisplayName("MemberNumber")]
    public string MemberNumber { get; set; }

    [LocalizedDisplayName("Email")]
    [DataType(DataType.EmailAddress)]
    public string Email { get; set; }

    [LocalizedDisplayName("FirstName")]
    public string FirstName { get; set; }

    [LocalizedDisplayName("LastName")]
    public string LastName { get; set; }

    [LocalizedDisplayName("Phone")]
    public string Phone { get; set; }

    [LocalizedDisplayName("ActiveOnly")]
    public bool Active { get; set; }
}

希望它可以帮助那里的任何人!
