Not work validation in last release 20.4.0.50

[Shek Mohammed Asiq Abdul Jabbar]

Hi Kavit,

We deeply regret for the inconvenience caused.

Further validating the issue, we determined that it requires significant changes to provide support for Data Annotation. So, we have considered this “Need to provide DataAnnotation support” as uncertain feature and added this feature request to our database. It will be implemented in any of our upcoming release.

You can now track the status of your request, review the proposed resolution timeline, and contact us for any further inquiries through this link.

Instead, you can use validation Rules for each column, as in the demo below.

Demo link : https://blazor.syncfusion.com/demos/tree-grid/dialog-editing?theme=fluent

Also, you can refer the API reference : https://help.syncfusion.com/cr/blazor/Syncfusion.Blazor.TreeGrid.TreeGridColumn.html#Syncfusion_Blazor_TreeGrid_TreeGridColumn_ValidationRules

[kavit]

I adhere to the general design for the entire application. Made adding an object to the dialog.

[Shek Mohammed Asiq Abdul Jabbar]

Hi Kavit,

We are quite unclear of your query. So please share the detailed explanation of the issue faced / query to proceed further.

[kavit]

the style (theme) of the application must be common for all windows, all elements, messages must be the same.

[Shek Mohammed Asiq Abdul Jabbar]

Hi Kavit,

Before proceeding this query, we need some more additional details to guide you in right way. So, we request to share us the following details:-

1. Whether the validation message was not shown while implementing the following demo?

Demo link : https://blazor.syncfusion.com/demos/tree-grid/dialog-editing?theme=fluent

2. The validation message does not depend on the themes, it shows based on the template(Validation rules) that we provide in tree grid columns. so, provide us complete tree grid code and explain in detail with Screenshot.
3. Video demo that replicates the issue.

Please provide us more information for better understanding of your query.

Regards,

Shek

I using ColumnTemplete for add and edit record in grid or treegreed.

[Shek Mohammed Asiq Abdul Jabbar]

Hi Kavit,

We appreciate your patience.

You can also apply validation rules for template column using ValidationRules property of the column as like the following code snippet :

<TreeGridColumn Field=@nameof(Tree.TaskName) HeaderText="TaskName" Width="120" Type="ColumnType.String" ValidationRules="@(new ValidationRules() { Required = true })">

            <Template>

                @{

                    var record = (context as Tree);

                    <div>

                        @record.TaskName

                    </div>

                }

            </Template>

        </TreeGridColumn>

Please get back to us if you are facing any difficulties on this.

Regards,

Shek

No. Validation only inside model with attribution [Required(ErrorMessage="")].....

[Farveen Sulthana Thameeztheen Basha]

Kavit,

As mentioned in previous update, currently we don’t have DataAnnotation support similar to this [Required(ErrorMessage="")] in TreeGrid.
So, we have considered this “Need to provide DataAnnotation support” as uncertain feature and added this feature request to our database. It will be implemented in any of our upcoming release.

[kavit]

Ok. Will wait.

[Shek Mohammed Asiq Abdul Jabbar]

Kavit,
