EditContext.IsModified() becomes true after updating bound property programmatically

[Augusto Barreto]

Hi,

When programmatically updating a bound property of any Syncfusion Blazor input component, it triggers a field change on the form marking the EditContext as modified.

This is not how the built-in blazor inputs work.

To see the difference, you can use the following code:

@page "/"
@using Syncfusion.Blazor.Inputs

<EditForm Model="@Dto1">
    <h4>
        Form with SfTextBox
    </h4>

    <SfTextBox @bind-Value="Dto1.Name"></SfTextBox>
    <br />
    <h4>
        EditContext.IsModified(): @context.IsModified()
    </h4>
</EditForm>

<hr />

<EditForm Model="@Dto2">
    <h4>
        Form with InputText
    </h4>

    <InputText @bind-Value="Dto2.Name"></InputText>
    <br />
    <h4>
        EditContext.IsModified(): @context.IsModified()
    </h4>
</EditForm>

@code{

    public class PersonDto
    {
        public string Name { get; set; }
    }

    public PersonDto Dto1 { get; set; } = new();

    public PersonDto Dto2 { get; set; } = new();

    protected override async Task OnInitializedAsync()
    {
        // Some call to the server to get some values
        await Task.Delay(5000);

        // Update some bound property on the dto
        Dto1.Name = "1111";
        Dto2.Name = "2222";
    }

}

Is there a way to change this behavior?

Thanks in advance
