Its Working highlighted in yellow background

----------------------------

function load(args) {
    this.columns[5].format = { type: 'date', format: 'dd-MM-yyyy' };

Modify your ViewModel to format the CloseDate property:

public class TestListViewModel
{
    private DateTime? closeDate;

    public DateTime? CloseDate
    {
        get
        {
            return closeDate;
        }
        set
        {
            closeDate = value;
            if (closeDate.HasValue)
            {
                // Format the date as "dd-MM-yyyy"
                CloseDateString = closeDate.Value.ToString("dd-MM-yyyy");
            }
            else
            {
                CloseDateString = string.Empty;
            }
        }
    }

    // Additional property to store the formatted date as a string
    public string CloseDateString { get; set; }
}

Update your grid configuration to use the CloseDateString property for displaying the formatted date.
