DevExpress实现GridControl单元格编辑验证的方法

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");
}
