Null value while editing inline a grid using the CrudUrl.

Hi,

I am trying to edit inline a grid using the CrudUrl. I use your Grid/UrlAdaptor example that I have modified like this:

[View]
        @Html.EJS().Grid("gridName").DataSource(ds => ds.Url(@Url.Action("UrlDatasource", "Grid")).CrudUrl("/Grid/SetCrud").Adaptor("UrlAdaptor")).AllowSorting().Columns(col =>
           {
               col.Field("OrderID").IsPrimaryKey(true).HeaderText("Order ID").Width("120").Add();
               col.Field("CustomerID").HeaderText("Customer Name").Width("170").Add();
               col.Field("Freight").HeaderText("Freight").Width("130").Format("C2").TextAlign(Syncfusion.EJ2.Grids.TextAlign.Right).Format("C2").Add();
               col.Field("ShipCity").HeaderText("Ship City").Width("120").TextAlign(Syncfusion.EJ2.Grids.TextAlign.Right).Add();
           }).EditSettings(edit => { edit.AllowAdding(true).AllowEditing(true).AllowDeleting(true).Mode(Syncfusion.EJ2.Grids.EditMode.Normal); }).Toolbar(new List<string>() { "Add", "Edit", "Delete" }).Render()


[Controller]
 public ActionResult SetCrud([FromBody]CRUDModel<Orders> value, string action)
{
            var ord = value.value;
...
}


When I delete a line, the value.Key in the controller is good. But when I update a line I only get null value.

Hi Laurent 

Sorry for the late reply 

We checked the attached sample and we can able to reproduce the mentioned issue at our end. When we validate the mentioned issue and we suspect that Model reference have been conflicted due to instance and property variable same. 

To resolve the issue we suggest to replace the name from value to myvalue. Please refer the below Code example and screenshot for your reference, 

Code Example: 
public ActionResult CrudUpdate(CRUDModel<OrdersDetails> myvalue) 
        { 
            var ordd = myvalue; 
           ….. 
       }

Hi,

I finally migrated my project to Asp.Net Core, .Net 5 and now my grid doesn't display the items of the grid.
I tried to migrate the sample you gave me but I can't figure it out.

Can you send me the same example in .Net 5 ?
Best regards,
Laurent

Hi Laurent 

Thanks for the update 

Based on your query we understand that you have faced difficulties while preparing the sample in the Framework .Net 5. We have prepared a sample based on your query Grid with CRUD Url.  

Please refer the below Code Example and sample for your reference 

<ejs-grid id="Grid" allowPaging="true" toolbar="@(new List<string>() {"Add", "Edit", "Update", "Delete" })"> 
    <e-data-manager url="/Home/UrlDatasource" crudUrl="/Home/CrudUpdate" adaptor="UrlAdaptor"></e-data-manager> 
    <e-grid-editSettings allowAdding="true" allowDeleting="true" allowEditing="true" mode="Normal"></e-grid-editSettings> 
    <e-grid-columns> 
        …………………. 
    </e-grid-columns> 
</ejs-grid> 


By default the JSON results are returned in camelCase format and the grid field names are also changed in camelCase. To resolve the issue Please add the below code in the startup.cs file. 

Startup.cs 
public void ConfigureServices(IServiceCollection services) 
        { 
            services.AddMvc().AddNewtonsoftJson(options => 
            { 
                options.SerializerSettings.ContractResolver = 
                    new DefaultContractResolver(); 
            }); 
        } 

Please refer the below Documentation for your reference,
