编辑，删除和分页不在动态webgrid上工作！ [英] Edit,delete and paging not working on dynamic webgrid!

问题描述

大家好，



我在MVC中使用webgrid它工作正常，它的编辑删除和分页操作工作正常。但是我在页面加载中有一些额外的要求我们有2下拉，所以在下拉列表的基础上我们必须绑定我的webgrid。

所以实现这个功能我从控制器创建webgrid所以一切都很好但是分页和编辑删除没有显示。我们怎么样实现这个....



i在视图部分中第一次加载webgrid就像 -

Hi All,

I am using webgrid in MVC it working fine, its edit delete and paging action working fine.But I have some extra requirement in page load we have 2 dropdown so on the basis of dropdown we have to bind my webgrid.
So implement this functionality i am creating webgrid from controller so everything is fine but paging and Edit delete is not showing.How we achieve this....

i have done webgrid for 1 st time load in View Section like -

@grid.GetHtml(htmlAttributes: new {id = "Gridv"},
    fillEmptyRows: true,
    alternatingRowStyle: "alternate-row",
    headerStyle: "grid-header",
    footerStyle: "grid-footer",
    mode: WebGridPagerModes.All,
    firstText: "<< First",
    previousText: "< Prev",
    nextText: "Next >",
    lastText: "Last >>",
    columns: new [] {
    grid.Column("Ordinal"),
    grid.Column("CourseName",header:"Course Name"),
    grid.Column("CourseDisplatTitle",header:"Description"),
    grid.Column("LanguageName",header:"Language"),
    grid.Column("ThemeName",header:"Theme"),
    grid.Column("LinkedCourses"),
    grid.Column("Enabled",header:"Active"),
    //grid.Column("FriendlyId", style:"hidecol",header:""),
    grid.Column(null,null, format: @<input type="hidden" name="IDHidden" value="@item.FriendlyId"/>),

    grid.Column("",
     header: "Actions",
     format: @<text>
     @Html.ActionLink("Edit",   "EditCourse",   new { id=item.CourseId} )
      |
     @Html.ActionLink("Delete", "DeleteCourse", new { id=item.CourseId} , new { onclick="return confirm('Are you sure?');"})
     </text>
        )
})

但是在第二次我们进行过滤时，我们在控制器中做的事情就像 -

but in 2 nd time when we do filter we are doing in controller like-

[HttpGet]
        [AcceptVerbs(HttpVerbs.Get)]
        public JsonResult CustomDataAll()
        {
            var tms = BusinessLayer.ThemeManager.GetThemes().ToList();
            var crs = BusinessLayer.CourseManager.GetCourses().ToList();
            var por = BusinessLayer.PortalManager.GetPortals();
            var mod = BusinessLayer.ModuleManager.GetModules().ToList();
            var result = from c in crs
                         join th in tms on c.ThemeId equals th.Id
                         //where c.ThemeId == themeid
                         join pr in por on th.PortalId equals pr.Id // where th.PortalId==portalid
                         join m in mod on c.Id equals m.CourseId into modules
                         select new
                         {
                             CourseId = c.Id,
                             CourseName = c.Name,
                             ThemeId = th.Id,
                             ThemeName = th.Name,
                             LanguageID = pr.Id,
                             LanguageName = pr.Name,
                             FriendlyId = c.FriendlyId,
                             Ordinal = c.Ordinal,
                             CourseDisplatTitle = c.CourseDisplayTitle,
                             Enabled = c.Enabled,
                             LinkedCourses = modules.Count()
                         };
            var grid = new System.Web.Helpers.WebGrid(result);

            var htmlString = grid.GetHtml();
return Json(new
            {
                Data = htmlString.ToHtmlString()
            }
                , JsonRequestBehavior.AllowGet);
        }

我无法在这2节中实现编辑删除和分页功能... ajax功能在第二次使用是这样的 -

I am not able to implement edit delete and paging functionality in this 2 section...which ajax funtion is using in 2nd time is like this-

<script type="text/javascript">
    $(function () {
        $('#modTheme_DataValueField').change(function () {
            var selectedValue = $(this).val();
            if (selectedValue != "") {
                $.ajax({
                    type: "GET",
                    contentType: "application/json; charset=utf-8",
                    url: '@Url.Action("CustomData", "ContentUpload")',
                    data: { "themeid": selectedValue },
                    dataType: "json",
                    beforeSend: function () {
                        //alert(id);
                    },
                    success: function (data) {
                        var items = "";
                        var i = 0;
                        $('#Gridv').html(data.Data);

                    },
                    error: function (result) {
                        //alert('Service call failed: ' + result.status + ' Type :' + result.statusText);
                    }
                });
            }
            else {
                $.ajax({
                    type: "GET",
                    contentType: "application/json; charset=utf-8",
                    url: '@Url.Action("CustomDataAll", "ContentUpload")',
                    data: { },
                    dataType: "json",
                    beforeSend: function () {
                        //alert(id);
                    },
                    success: function (data) {
                        var items = "";
                        var i = 0;
                        $('#Gridv').html(data.Data);

                    },
                    error: function (result) {
                        alert('Service call failed: ' + result.status + ' Type :' + result.statusText);
                    }
                });
            }
        });
    });

</script>

推荐答案

（function（）{

(function () {

（' ＃modTheme_DataValueField'）。change（function（）{
var selectedValue =

('#modTheme_DataValueField').change(function () { var selectedValue =

（ this ）。val（）;
if （selectedValue！= ）{

(this).val(); if (selectedValue != "") {
