如何使必需的字段验证器仅在控件验证可见时才能工作 [英] how to make required field validator to work only when control to validate is visible

问题描述

我想知道只有在目标控件的可见属性为true的情况下才能使所需的字段验证器起作用！可以使用启用"属性:

 此 .textInputValidator.Enable = 此 .txtInputData.Visible; 

您也可以在JavaScript中执行以下操作:

  var  hdnReqField = 文档 .getElementById(  hdnReqFieldValidator").value;
 var  ReqField = 文档 .getElementById(hdnReqField);

ValidatorEnable(ReqField， false ); // 用于禁用 

ValidatorEnable-是JavaScript中的内置函数.
传递"true"以启用验证器.

希望这会有所帮助.

I want to know how can we make required field validator to work only when the visible property of it''s target control is true !!

解决方案

You can use "Enable" property:

this.textInputValidator.Enable = this.txtInputData.Visible;

You can also do this in JavaScript as given below:

var hdnReqField = document.getElementById("hdnReqFieldValidator").value;
var ReqField = document.getElementById(hdnReqField);

ValidatorEnable(ReqField, false); //For Disabling

ValidatorEnable - is a inbuilt function in JavaScript.
Pass "true" for enabling the validator.

Hope this will help.
