Dialog Template Not Work In Net Core 3.0

[luis]

I tried the solution from this thread (https://www.syncfusion.com/forums/141281/implement-dialog-template-under-grid-ejs-grid), but it didn't work. When I click on the Add or Edit button in dialog template.

What am I missing? (I'm using ASP.NET Core 3 EJ2, Views and Controllers, Razor pages, Entity Framework and sql server).

Hi Luis, 

Thanks for contacting us. 

We have checked the code example and screenshots that you have provided. We could see that you have not defined template for primary key column in both edit and add partial views. While editing the it is necessary to include primary key values while editing 

Please find the below documentation link for more information. 

Documentation: https://ej2.syncfusion.com/aspnetcore/documentation/grid/edit/#troubleshoot-editing-works-only-for-first-row 

Please share the video demonstration of the issue, and explain the issue you are facing, (like script error or updated data is not reflecting in Grid).  

Please find the below code example and  the below screenshots to ensure the primary key values are passed to server side properly.

but it didn't work. When I click on the Add or Edit button in dialog template.

insertUrl="/Cargos/Insert" updateUrl="/Cargos/Update" related to IActionResult Insert and IActionResult Update Can not be executed.

In mode dialog normal It works perfect

What am I missing?, Please help me.

Hi luis, 

 

Thanks for your update. 

 

We have tried to replicate the issue at our end. But it is working fine. We are able to add and update the data. Also we are attaching the sample for your reference. 

 

Sample: https://www.syncfusion.com/downloads/support/forum/149632/ze/141281-dialog-template-urladaptor_Sample82178496.zip 

 

It would be helpful to us to validate the issue, if you share the below details, 

 

1. Share the Syncfusion Nuget(Syncfusion.EJ2.AspNet.Core) version and CDN link version

 

2. Share if any console error thrown(Since you are mentioning normal and dialog mode it is working fine and cannot access the Insert,

Update methods in dialog template, you might have some script errors in console) 

 

3. Bind the actionFailure event to Grid and share the stack trace (if any)

 

4. If you have not any errors in console and actionFailure events , try to reproduce the issue in given sample, are share the issue reproducible sample

 

Regards, 

Pavithra S.

1.      Share the Syncfusion Nuget(Syncfusion.EJ2.AspNet.Core) version and CDN link version

2. Cannot access the Insert, Update methods controller in mode dialog template. not show any errors in console or actionFailure events.

 

3. Trace with http debugger.. When I click on the Add or Edit button in mode dialog template. No fire the Insert, Update methods of controller. 

What am I missing? (I'm using ASP.NET Core 3 EJ2, MVC, Entity Framework Core 3 and sql server database).

Hi luis, 

Thanks for sharing the requested details. 

We have tried to replicate the issue with the mentioned versions. But we were unable to replicate the reported issue at our end. The dialog template is working fine in our end. To validate further about the issue, please do the changes to reproduce the issue in the given sample and revert to us.

Thanks, I share the project for you to understand the problem better, it contains your example along with mine.
you example is Home, the mine is cargos.


you example requires the following:

services.AddControllersWithViews().AddNewtonsoftJson(options =>

            {

                // Use the default property (Pascal) casing

                options.SerializerSettings.ContractResolver = new DefaultContractResolver();

            });

I have solved the problem

 

Initial capital letter in field Name

 

<e-grid-column field="Id" isPrimaryKey="true" visible="false"></e-grid-column>

            <e-grid-column field="Codigo" headerText="Código" validationRules="@(new { required=true})" width="20"></e-grid-column>

            <e-grid-column field="Nombre" headerText="Nombre" validationRules="@(new { required=true})" width="80"></e-grid-column>

            <e-grid-column field="Basico" headerText="Básico" validationRules="@(new { required=true})" width="40" textAlign="Right" editType="numericedit" format="N2"></e-grid-column>

 

Change the model propery as Nullable

public partial class CargoSet

    {

        [Key]

        public Nullable<int> Id { get; set; }

        public string Codigo { get; set; }

        public string Nombre { get; set; }

 

In Startup file

 

services.AddControllersWithViews().AddNewtonsoftJson(options =>

            {

                options.SerializerSettings.ContractResolver = new DefaultContractResolver();

            });

 

Thank you …

Hi Luis,

Thanks for the update.

We are happy to hear that you have you resolved the problem.

Hi, from your example 141281-dialog-template-urladaptor_Sample82178496.zip 

the CRUDModel value is null unless I enter a value for Order ID and Freight. Seems to be number related.  Any suggestions?

Thanks

[luis]

I use a database with autoincremental id. I don't need to send that id value, I can leave it null or empty. That is why I have solved the problem for my case as explained.

[Dhivya Rajendran]

Hi Arian, 

Greetings from Syncfusion support. 

 

Query : the CRUDModel value is null unless I enter a value for Order ID and Freight. Seems to be number related.  Any suggestions? 

 

From your shared sample we found that you were defined a number variables without a null coalescing operator so that we can’t able to  assign a null value to a number variable. Refer the below reference link for more information and you can resolve the reported problem by using null coalescing operator ( ? ) in that variable. 

Reference Link: https://dzone.com/articles/nullable-types-and-null-coalescing-operator-in-c 

Please change your controller side code as like given below. 

public class Orders 

        { 

            public Orders() 

            { 

 

            } 

            public Orders(long OrderId, string CustomerId, int EmployeeId, double Freight, DateTime OrderDate, string ShipCity) 

            { 

                ------ 

           } 

            public long? OrderID { get; set; } 

            public string CustomerID { get; set; } 

            public int EmployeeID { get; set; } 

            public double? Freight { get; set; } 

            public DateTime OrderDate { get; set; } 

            public string ShipCity { get; set; } 

        } 

Note : CRUD operations depends the primaryKey field and we did not specify the null value for primary key column so make sure to specify the unique value for that column. 

We also have client side validation support for Grid. Please refer the below documentation for more information. 

https://ej2.syncfusion.com/aspnetcore/documentation/grid/edit/?no-cache=1#column-validation
