Regarding Teta's answer,you would initialize ValOn and ValOff like this:

    CheckBox0.ValOn = "Y";
    CheckBox0.ValOff = "N";

You also need to setup a DataSource for the Checkbox for it to work properly:

    oForm.DataSources.UserDataSources.Add("CheckboxDS", BoDataType.dt_SHORT_TEXT, 1);
    CheckBox0.DataBind.SetBound(True, "", "CheckboxDS");

    // this sets the checkbox to checked
    oForm.DataSources.UserDataSources.Item("CheckboxDS").Value = "Y";

创建复选框时，尝试设置valOn和valOff
