Hi,

My grid is not able to see on screen. I am using grid in partial view. I used this grid in many places where it is working absolutely fine. I tried lot to find issue but no success. I also observed that it is not generating grid in html.
Strange thing is rest of the control is appearing on screen except grid.

This is my partial View

@model ERSCore.Models.PurchaseRequestModel
<div class="row" style="width: 100%; padding-bottom: 5px;">
    <div class="col-md-3" style="padding-right:0px;">
        Employee Code / Name
    </div>
    <div class="col-md-1" style="padding-right:0px;">
        @Html.TextBoxFor(model => model.EmployeeID, new { @class = "form-control  input-sm", @disabled = "disabled" })
    </div>
    <div class="col-md-2" style="padding-right:0px;">
        @Html.TextBoxFor(model => model.EmployeeName, new { @class = "form-control  input-sm", @readonly = "readonly" })
    </div>
    <div class="col-md-3" style="padding-right:0px;">
        No.
    </div>
    <div class="col-md-3" style="padding-right:0px;">
        <div style="float:right;">
            @Html.TextBoxFor(model => model.DocNum, new { @class = "form-control  input-sm", @readonly = "readonly", @style = "width:170px" })
        </div>
        <div style="float:left;">
            @Html.DropDownListFor(model => model.Series, new SelectList(Model.SeriesList, "Code", "Name"), new { @class = "form-control  input-sm", @disabled = "disabled", @style = "width:100%" })
        </div>
    </div>
</div>
<div class="row" style="width: 100%; padding-bottom: 5px;">
    <div class="col-md-3" style="padding-right:0px;">
        Project
    </div>
    <div class="col-md-3" style="padding-right:0px;">
        @Html.DropDownListFor(model => model.ProjectCode, new SelectList(Model.Projects, "Code", "Name", "Extra1", 1), new { @class = "form-control  input-sm", @disabled = "disabled" })
    </div>
    <div class="col-md-3" style="padding-right:0px;">
        Status
    </div>
    <div class="col-md-3" style="padding-right:0px;">
        @Html.DropDownListFor(model => model.StatusCode, new SelectList(Model.StatusList, "Code", "Name"), new { @class = "form-control  input-sm", @disabled = "disabled" })
    </div>
</div>
<hr style="color:blue;" />
<div class="row" style="width: 100%; padding-bottom: 5px;">
    <div class="col-md-12">
        @(Html.EJ().Grid<ERSCore.Models.LineItem>("RequestView_data")
                            .AllowScrolling(true)
                            .EnableAltRow(true)
                            .EnableResponsiveRow()
                            .PageSettings(m => m.PageSize(10))
                            .EnableHeaderHover(true)
                            .AllowTextWrap()
                            .AllowPaging()
                            .Columns(col =>
                            {
                                //col.Field("DocEntry").HeaderText("DocEntry").IsPrimaryKey(true).TextAlign(TextAlign.Right).Width(50).TextAlign(System.Web.UI.WebControls.TextAlign.Left).Add();
                                col.Field("DisplayText").HeaderText("Description").Width(800).Add();
                                col.Field("Amount").HeaderText("Amount").Type("int").Width(70).Add();

                            })
                             .Datasource((System.Collections.IEnumerable)Model.Lines)
        )
</div>
</div>

This is my dialog window in which it should appear.

   <div>
        @{Html.EJ().Dialog("RequestDetails").Title("Travel Request Details").Width(1200).Height(600).ShowOnInit(false)
              .EnableModal(true).Render();}
    </div>

Through JavaScript I am calling controller method to get partial view with data.

   $.ajax({
            url: "/PurchaseRequest/Details",
            type: "POST",
            data: { id: args.data.DocEntry },
            error: function (a, b, c) {
            

            },
            success: function (e) {
      
                $("#RequestDetails").ejDialog("setContent", e);
                eDialog = $("#RequestDetails").data("ejDialog");
                if (eDialog.model)
                    eDialog.open();
               
            }

        });

My Control is :

 [Filters.B1Authentication()]
        public ActionResult Details(int id)
        {
            ERSCore.Models.ERLoginResultModel rModel = new ERSCore.Models.ERLoginResultModel();
            if (Session["Session"] != null)
                rModel = (ERSCore.Models.ERLoginResultModel)Session["Session"];

            purchaseRequest = new ERSCore.Controllers.SQL_PurchaseRequestController(rModel);
            ERSCore.Models.PurchaseRequestModel prModel = purchaseRequest.GetDraftRequestByID(id, rModel);
            return PartialView(prModel); // this is returning html for my view but no grid html.
           
        }

Hi Manish,

Thanks for contacting Syncfusion support.

We analyzed your code snippet and found that you have not specified the @Html.EJ().ScriptManager() at the end of the Partial View.  The ScriptManager() is used to render the ejControls.

Please find the code example:


@(Html.EJ().Grid<SampleApp.Models.OrdersView>("FlatGrid")

        .Datasource((IEnumerable<object>)ViewBag.datasource)

        .AllowPaging()

        .AllowScrolling()

        .EnableAltRow()

        .EnableResponsiveRow()

        .EnableHeaderHover(true)

        .AllowTextWrap()

        .PageSettings(page => { page.PageSize(4); })

        ---------------------

       .EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing().EditMode(EditMode.Dialog); })

        .Columns(col =>

        {

            col.Field("EmployeeID").HeaderText("Employee ID").IsPrimaryKey(true).TextAlign(TextAlign.Right).Width(100).Add();

            col.Field("OrderID").HeaderText("Order ID").Width(100).Add();

            col.Field("ShipCity").HeaderText("Ship City").Width(100).Add();

            col.Field("OrderDate").HeaderText("Order Date").TextAlign(TextAlign.Right).Width(100).Format("{0:MM/dd/yyyy}").Add();

            col.Field("ShipCountry").Width(100).HeaderText("Ship Country").Add();

        })

)




@Html.EJ().ScriptManager()

Hi Prasanna,

Does it required to set @Html.EJ().ScriptManager() on each page where the grid is?
I don't think it is required. This line is already there in my _layout.cshtml page.

This is snippet from my _layout.cshtml page:

 <div class="container body-content" id="xBody">
            @RenderBody()
        </div>
@Html.EJ().ScriptManager()

Hi Manish,

 

Query : “Does it required to set @Html.EJ().ScriptManager() on each page where the grid is?”

 

The main reason for referring the ScriptManager in _Layout file is that, it can be referred as common by all the View files present within your application. When we  rendering the Grid in partial view using ajax the ScriptManager will not referred for the partial view. So, we need to manually include the  scriptmanager for each partial view.

 

Kindly let me know whether you are having more number of partial view in your application if yes please explain the scenario of how you are using the partial view. So that we can provide you the appropriate solution.

Hi Prasanna,

Thanks for you support. As you instructed I am to display grid, it creates pager and rows also but I am unable to display text.
Please see the below screen shot.



On further investigation i observed that html string is building properly but not able to see this on screen.
Please see the screen shot below.



In this investigation I observed that this particular grid is not rendering properly on Internet Explorer 11.0 where as it is showing data / working in FireFox.
Please see the screen shot.



Can you please let me know what could be the issue?

Hi Manish,

We checked your screenshots and suspect that you are initializing the grid with the hidden element. After retrieved the data from the server using AJAX post you are displaying the grid. When we initialize the grid with the hidden element by enable the allowScrolling property, the width and height of the grid will be initialized as zero. Due to the time delay to show the hidden element in IE browser, grid content was set with 0px height and 0px width. This is  the reason for grid content is not displaying in IE browser.

If you are also facing the issue in the above scenario then we suggest you to refresh the scroller after rendering the grid.

Please refer to the below code example.


<div id="main" style="display:none">

<script type="text/javascript"> 

        $.ajax

                ({

                    url: "/Home/Productpartial",

                    type: 'GET',

                    success: function (data) {

                        $("#main").html(data);

                        $("#main").css('display', 'block');

                        var grid = $("#FlatGrid").ejGrid("instance");

                        grid._refreshScroller({requestType:'refresh'});

                    }

                });
</script>
