我要评论本文实例演示了devexpress实现gridcontrol单元格编辑验证的方法，比较实用的功能，具体方法如下：
主要功能代码如下：
/// <summary>
/// 自定义单元格验证
/// </summary>
/// <param name="view">gridview</param>
/// <param name="e">basecontainervalidateeditoreventargs</param>
/// <param name="fieldnamehandler">委托</param>
/// <param name="errorhanlder">委托</param>
/// <param name="errortext">当验证不通过对时候，错误提示信息文字</param>
public static void customvalidatingeditor(this gridview view, basecontainervalidateeditoreventargs e, predicate<string> fieldnamehandler, predicate<object> errorhanlder, string errortext)
{
/*说明
*在validatingeditor事件使用
*eg:
*string[] worktype = new string[4] { "-1", "关闭但不删除", "启用", "删除" };
*void gvlampconfig_validatingeditor(object sender, devexpress.xtraeditors.controls.basecontainervalidateeditoreventargs e)
*{
* gridview _view = sender as gridview;
* _view.customvalidatingeditor(e, fieldname => fieldname.equals("tlampworkstatus"), value => !worktype.contains<string>(value.tostring()), "若想设置为不修改，请输入-1即可");
* }
*/
if (fieldnamehandler(view.focusedcolumn.fieldname))
{
if (errorhanlder(e.value))
{
e.valid = false;
e.errortext = errortext;
}
}
}
代码使用方法如下：
string[] worktype = new string[4] { "-1", "关闭但不删除", "启用", "删除" };
void gvlampconfig_validatingeditor(object sender, devexpress.xtraeditors.controls.basecontainervalidateeditoreventargs e)
{
gridview _view = sender as gridview;
_view.customvalidatingeditor(e, fieldname => fieldname.equals("tlampworkstatus"), value => !worktype.contains<string>(value.tostring()), "若想设置为不修改，请输入-1即可");
}
