TextEdit不能空验证设置

在工具箱中找到dxValidationProvider控件拖拉到界面上，添加代码

ConditionValidationRule notEmptyValidationRule = new ConditionValidationRule();
notEmptyValidationRule.ConditionOperator = ConditionOperator.IsNotBlank;
notEmptyValidationRule.ErrorText = "请输入 该表单不能为空！";
dxValidationProvider1.SetValidationRule(BulidName, notEmptyValidationRule);//两个参数表示验name值为BulidName的TextEdit控件为notEmptyValidationRule验证
