CheckBox and DataGridViewCheckBoxColumn customization

For the DataGridViewCheckBoxColumn use the TrueValue and FalseValue properties.

dataGridView.Columns.Add(new DataGridViewCheckBoxColumn() { 
    TrueValue = "Y",
    FalseValue = "N",
});

For the CheckBox use the Parse and Format events like this:

private void Binding_Format(object sender, ConvertEventArgs e)
{
  e.Value = Object.Equals(e.Value, "Y");
}

private void Binding_Parse(object sender, ConvertEventArgs e)
{
 e.Value = (Object.Equals(e.Value, true) ? "Y" : "N");
}

Note: Attach the event handler before adding the binding object.

This works for checkbox:

public class CheckBoxYN : Wisej.Web.CheckBox

    {

        public string YesNo

        {

            get

            {

                if (this.Checked)

                    return “Y”;

                else

                    return “N”;

            }

            set

            {

                if (value == “Y”)

                    this.Checked = true;

                else

                    this.Checked = false;

            }

        }

    }

and then in page/control/window where you are using this control you need to set databinding to it using:

this.chkExtenede.DataBindings.Add(“YesNo”, <binding source name>, <field to bind to name>);
