将GridView中的CheckBoxField绑定到不支持布尔类型的Oracle

问题描述

我有一个Gridview，其中有一些到数据源的boundfield列.我还有一个checkboxfield，如果要接收特定的整数值(1)，我想对其进行检查，而对于(0)，则不对其进行检查.因为我已经有一个问题，Oracle没有布尔类型和asp.net(取决于将复选框标记为boolean).请帮忙

I have a gridview with some boundfield columns to my data source. I have also a checkboxfield that I want checked it if it recieves a particular integer value (1) for example and unchecked it for (0). because I have a problem already that Oracle doesn''t have a boolean type and asp.net depending on boolean to mark the checkbox. Please help
