推荐答案

验证组可帮助您将控件分组在单个页面中.以下示例将帮助您实现这一目标:

The validation groups help you to group the controls in a single page. Following examples will help you implement that:

Hello Dinesh，

您可以使用下面的代码片段来验证哪些验证已失败

this.Validators.Where(v =>！v.IsValid

Hello Dinesh,

You can use below snipet to validate which validation is pfailed

this.Validators.Where(v => !v.IsValid


Please let us know if any.

set应该将所有文本框和按钮的validationGroup属性设置为相同.

set should set validationGroup Property same for all textbox and button .
