Checkbox not showing checked

[S]

I upgrade from 'telerik.ui.for.aspnet.core.2019.1.220.commercial' to 'telerik.ui.for.aspnet.core.2023.1.117.commercial' and now the check box doesn't display check even though the data from the database is true

@(Html.Kendo().CheckBox() .Name("MyCheckbox").Label("Yes")

I even tried @(Html.Kendo().CheckBox() .Name("MyCheckbox").Checked(true).Label("Yes"), it still won't show the checkbox as checked.

Regards

I used checkbox:

 

<div class="col-md-2">
 <label for="MyCheckBox">Is this an Invasive Species?</label><br />
 @(Html.Kendo().CheckBoxFor(m => m.Checked).Label("MyCheckBox"))
</div>

but now I am getting:

VM1552:1  Uncaught TypeError: jQuery(...).kendoCheckBox is not a function

Hi,

At first glance, I did not see anything apparent within the CheckBox configuration that could potentially cause the sporadic behavior from persisting.

In this regard, I have further tried reproducing the behavior within an isolated sample whilst producing the following result:

Notice that I have tested with two Checkboxes. One by using the conventional HtmlHelper and the other using the <WidgetName>For Helper. For example:

@(Html.Kendo().CheckBox()
    .Name("MyCheckbox")
    .Checked(true)
    .Label("Yes")
)


@(Html.Kendo().CheckBoxFor(m => m.Checked))

 Where the second CheckBox is bound to the following model:

public class CheckBoxModel
{
    public bool Checked { get; set; } = true;
}

I tried further reciprocating the issue and noticed that the same behavior would be present if the client-side resources are not corresponding to the version of the NuGet package.

Generally, upgrading through the NuGet Package Manager will not update the included client-side files. Therefore, you will need to upgrade the files manually in order for the files to be up-to-date with the corresponding version of the NuGet package:

That being said, I recommend upgrading the included client-side files within the _Layout.cshtml of the application and observing whether the behavior persists. More information regarding the upgrade process is available within our documentation which can be found here:

In addition, since you are doing a significant upgrade, I would recommend going over our breaking changes article, as they were inducted a significant amount of changes for a large portion of the Telerik UI for ASP.NET Core components:

• Breaking Changes

Notice that the yearly release changes are located on the left-hand side:

That being said, I noticed that there is no license associated with your account which further limits our support service.

Thus, I strongly recommend that you either purchase or renew your license in order to gain access to the latest updates, fixes, features, and support regarding the Telerik UI for ASP.NET Core components. More information regarding the currently available plans can be reviewed here:

• Support Plans

Nevertheless, attached you will find a runnable sample that was used for further testing purposes. If possible, could you please consider replicating the behavior within the attached sample and send it back for further examination if the mentioned above suggestion does not help?

Kind Regards,
Alexander
