Checkbox doesn't change value

[Tom Dimos]

Hello, I have a problem changing the value of a CheckBox(the blue tick doesn't appear if it was false initially). I use the CheckBox as a template inside of a grid column. I check a condition and based on the returned value I set the Checked property of CheckBox. Then if I use an event like onchange the value doesn't change. If I remove the event I can change the value(the blue tick appears).Here is my code:

<Template>

                    @{

                        var point = (context as Point);

                        bool isChecked;

                        if(point.PointName == Name){

                            isChecked = true;

                        }else{

                            isChecked = false;

                        }

                        <SfCheckBox Checked = "@isChecked" @onchange = "OnChange"></SfCheckBox>

                    }

</Template>

private void OnChange(Microsoft.AspNetCore.Components.ChangeEventArgs args)

{

  Console.WriteLine(args.Value);

}

Hi Tom, 

 

We have checked your reported query, we have resolved your reported issue using two way binding Checked property. Please refer below code snippets. 

 

<SfCheckBox @bind-Checked="@isChecked" Label="CheckBox" ValueChange="ValueChange" TChecked="bool"></SfCheckBox> 

@code { 

 

 

    private bool isChecked = false; 

    private string point = "one"; 

 

    private void ValueChange(ChangeEventArgs<bool> args) 

    { 

        if (point == "one") 

        { 

            isChecked = true; 

            point = "two"; 

        } 

        else 

        { 

            isChecked = false; 

            point = "one"; 

        } 

        Console.WriteLine(args.Checked); 

    } 

}

This wasn't exactly what I intended to do but @bind-Checked was part of it. Thanks!!!
