Asked On June 25, 2014 03:07 PM UTC

Hi,

I have a main view containing the htlm helper (Ajax.BeginForm) and in order to get it working i added the required scripts and changed in my webconfig the UnobtrusiveJavascriptEnabled to true.

My ajax request works fine and returns a PartialView containing only the EJ().Grid and the Script Manager in the end.
In my main page the PartialView is loaded with the html and script from the Grid but there's no visible Grid.

The Grid loads fine if i use an anchor with jquery ajax and UnobtrusiveJavascriptEnabled to false.
Is there any way i can load the grid without having to set UnobtrusiveJavascriptEnabled to false so i can use the html helper ?

Hi Huntero,

 

Thanks for using Syncfusion products.

 

Query: “Is there any way i can load the grid without having to set UnobtrusiveJavascriptEnabled to false so i can use the html helper ?”

 

Normally while setting the UnobtrusiveJavascriptEnabled as true in web.config, the grid properties will be set as the attributes of the div in which the attributes are prefixed with “data-ej-” and we must initiate the control rendering in the success event of the Ajax.BeginForm. Please refer the following code snippet.

 

[cshtml]

@using (Ajax.BeginForm("GetPartial", "Home", new AjaxOptions()

   {

       UpdateTargetId = "gridcontainer",

       OnSuccess = "success"   //Ajax Success Event

   }))

    {

        <input type="submit" value="GetPartial" />

    }

 

[javascript]

 

function success() {

            ej.widget.init();     //Initiate the Control rendering

        }

 

 

 

Please try the above solution and let us know if you require further assistance.

Madhu Sudhanan. P

Hi again,

I have 2 issues that i faced when trying to add a custom toolbar item in the same Grid i mentioned above.

1 ) I added the following code to the Grid:
        .ToolBar(toolbar =>
            {
                toolbar.AllowToolBar(true).CustomToolbarItems(new List<object>() { "Expand"});
            })

But it seems to be rendering incorrectly, as my output is:
        <ul class="e-ul e-horizontal">
            <li title="["
            <li title="E 
        </ul>

Each list item has the title of a word of my Toolbar Item.

2) I wanted to call a Dialog when i click the toolbar item, so that i can add new items for my Model.
Based on that i created a small example ill add below, but the close button and my content is non existant.

                @Html.EJ().Dialog("form-create").Title("Test").Items(data =>
                   {
                       data.ContentTemplate(@<div style="margin: 5px 14px">
                        <div>
                            123
                        </div>
                    </div>);
                   }).Render()

Thanks for the amazing costumer support provided.

Hi Huntero,

 

Please find the response.

 

Query #1: “i faced when trying to add a custom toolbar item in the same Grid”

 

We have confirmed that the issue with "Issue with customToolBar in Unobtrusive mode" is a defect and we have logged a defect report. The fix for this issue is estimated to be available in our upcoming Volume 2, 2014 release.

 

Query #2: “I wanted to call a Dialog when i click the toolbar item, so that i can add new items for my Model.”

 

We have in-built support for Dialog editing in grid. And the dialog can also be opened by clicking the toolbar items. We can set the dialog editing in grid as follows.

 

[cshtml]

@(Html.EJ().Grid<OrdersView>("Editing")

. . .

.EditOption(edit => edit.AllowAdding().AllowDeleting().AllowEditing().EditMode(EditMode.Dialog))

.Toolbar (toolbar.AllowToolBar().ToolBarItems(items =>

            {

                items.AddTool(ToolBarItems.Add);

                items.AddTool(ToolBarItems.Edit);

                items.AddTool(ToolBarItems.Delete);

                items.AddTool(ToolBarItems.Update);

                items.AddTool(ToolBarItems.Cancel);

            });

        })))

. . . . .

.Render())

 

 

The MVC Grid contains two types of dialog editing, they are Dialog and DialogTemplate. The DialogTemplate allows you to create a template for the data that you require to be edited using the Dialog Box.This means you can edit any of the fields pertaining to a single record of data and apply it to a template so that the same format is applied for all the other records that you will edit later.

 

Please refer the following link for the Dialog editing and Dialog template editing in MVC Grid.

 

http://mvc.syncfusion.com/demos/web/Grid/DialogEditing

 

Please let us know if you want to open the dialog by clicking the custom  toolbar item.

 

Regards,

Madhu Sudhanan. P

Hello Madhu Sudhanan. P

Thank you for your answer.

The DialogTemplate was kind of what i was looking for, but my problem is, i wanted the Dialog body to be loaded from a partial view that i have in my controller instead of adding the javascript for the body, so that i can use the same Model and html for the create and edit/delete based on the id from the selected row in the Grid.

I was wondering if this was possible using the DialogTemplate and ajax.

Best regards.

Hi Huntero,

 

Please find the response.

 

We can get the dialog template content from the controller using Partial View and Jquery Ajax. Please refer the following code snippet.

 

The following code shows the Partial View that contains the Dialog template.

 

[Partial View]

 

<div>

    <b>Order Details</b>

    <table cellspacing="10">

        <tr>

            <td style="text-align: right;">

                Order ID

            </td>

            <td style="text-align: left">

                <input id="OrderID" name="OrderID" value="{{: OrderID}}" disabled="disabled" class="e-field e-ejinputtext valid e-disable" style="text-align: right; width: 116px; height: 28px" />

            </td>

            <td style="text-align: right;">

                Customer ID

            </td>

            <td style="text-align: left">

                <input id="CustomerID" name="CustomerID" value="{{: CustomerID}}" class="e-field e-ejinputtext valid" style="width: 116px; height: 28px" />

            </td>

        </tr>

. . . . .

    </table>

. . . .

 

 

The following code shows the controller returns the Partial View.

 

[controller]

public ActionResult DialogContent() {

          

            return PartialView("_dialogContent");

        }

 

 

In the actionBegin event, the ajax request will be made to the Controller to get the Dialog content and in the success event, the template will be placed in the template container which is placed in the view page as follow.

 

 

<div id="template" style="display: none"></div> <!--Dialog Container-->

 

@(Html.EJ().Grid<object>("Grid")

        .Datasource((IEnumerable<object>)ViewData["data"])

        .EditOption(edit => { edit.AllowDeleting().AllowEditing().AllowAdding().EditMode(EditMode.DialogTemplate); })

        . . . .

        .ClientSideEvents(eve=>eve.ActionBegin("beginEdit").ActionComplete("complete"))

        .Render())

 

<script>

    function beginEdit(args) {

        if (args.requestType == "beginedit") {

            $.ajax({

                url: "/Home/DialogContent",

                async: false,

                success: function (data) {

                    $("#template").html(data);   //Updating the dialog container with the partial view data

 

                    $("#Grid").ejGrid("option", { edit: { dialogEditorTemplateId: "#template" } })

                    //setting the dialog template

                },

                error: function (e) {

                    args.cancel = true;

                }

            });

        }

    }

 

 

 

For your convenience, we have created a simple grid sample in which the edit dialog template is loaded from the Partial View and the same can be downloaded from the below location.

 

Sample Location: PartialViewDialog.zip

 

Please let us know if you have any queries.

Madhu Sudhanan. P

Thank you for the fast answer.

I found out today that the dropdownlist issue i had was related to the css i changed in the dropdowns where the line-height was hiding the text only in IE.

On the 2nd topic the link provided has great details about the documentation i was looking for, but when i try to access the iconlibrary in the Button > Overview and select Built-in Icon: Supports the built-in icon libraries ,in the following link http://help.syncfusion.com/ug/Documents/ej.iconslibrary.docx  i get an ASP.Net Web Config Error.

Hi Siraj, 

Syncfusion MVC components will render in two modes such Unobtrusive mode and non-unobtrusive mode. 
 
For Non-Unobtrusive mode, we need to refer ScriptManager() in partial view page and also refer to the below code example for render Grid using ajax call(partialView). 

Index.cshtml 

<div> 
                @Html.EJ().Button("click").Text("Render Grid").ShowRoundedCorner(true).Size(ButtonSize.Small) 
 
            </div> 
<div id="main"/> 
    <script type="text/javascript"> 
        $("#click").click(function () { 
            $.ajax 
                    ({ 
                        url: "/Home/Productpartial", 
                        type: 'GET', 
                        success: function (data) { 
                            $("#main").html(data); 
                                                 } 
                    }); 
 
        }); 
    </script> 
@(Html.EJ().ScriptManager()) 
_homeContent.cshtml 
 
@(Html.EJ().Grid<SyncfusionMvcApplication7.Models.ModelT>("GridContainer") 
 
}) 
) 
 
@Html.EJ().ScriptManager() 
 
 
For Unobtrusive mode, there is no need to refer the ScriptManager() in each partial views but to initiate the control in the partial, we have to use ej.widgets.init.  

Web.config 
 
 <appSettings> 
   .  . .  
    <add key="UnobtrusiveJavaScriptEnabled" value="true" /> 
  </appSettings> 
 
_layout.cshtml 
 
<!DOCTYPE html> 
<html> 
<head> 
     . . . . ..  
    <script src="~/Scripts/ej/ej.web.all.min.js"></script> 
    <script src="~/Scripts/ej/ej.unobtrusive.min.js"></script> 
</head> 
<body> 
    @RenderBody() 
    @(Html.EJ().ScriptManager()) 
</body> 
</html> 
 
 
 
Index.cshtml 

<div> 
                @Html.EJ().Button("click").Text("Render Grid").ShowRoundedCorner(true).Size(ButtonSize.Small) 
 
            </div> 
<div id="main"/> 
    <script type="text/javascript"> 
        $("#click").click(function () { 
            $.ajax 
                    ({ 
                        url: "/Home/Productpartial", 
                        type: 'GET', 
                        success: function (data) { 
                            $("#main").html(data); 
                            ej.widget.init($("#main")); //initialize the ejwidgets when unobtrusive is true 
                        } 
                    }); 
        }); 
    </script> 
@(Html.EJ().ScriptManager()) 
 
Note: For an Unobtrusive mode, you have to refer the ej.unobtrusive.min.js in the _layout page of your application.

Jayaprakash K.
