RequiredField验证器 [英] RequiredField Validator

问题描述

我在页面中有下拉菜单和文本框，并为它们都放置了必填字段验证器.如果我单击按钮，它将首先验证文本框而不是下拉列表.因为下拉列表位于第一行.如何解决此问题?

问候，

推荐答案

检查以下内容以设置所需的字段验证器

要将必需的字段验证器用于多列，请检查以下内容:

多个字段验证器-一个ASP.NET验证控件 [

check the following for setting up required field validator

http://asp.net-tutorials.com/validation/required-field-validator/[^]

To use required field validator for multiple columns, check this:

Multiple Fields Validator - An ASP.NET Validation Control[^]

这两个验证都将完成同时.

单击按钮之前是否要更改DropDownList的索引?

The validation will be done for both of them simultaneously.

Are you changing the index of the DropDownList before clicking the button?
