推荐答案

使用datagrid的Itemdatabound或gridview的RowDatabound事件访问行级别的控件.只需在数据绑定时将Javascript方法绑定到控件，即可自动触发验证事件.

因此，您需要的是将属性添加到文本框(或其他控件)，在此onchange/onblur调用JS方法.也将控件的值作为参数传递.现在，您就具有了价值，进行所需的验证，并在需要时继续进行操作.

Use datagrid''s Itemdatabound or gridview''s RowDatabound event to access controls at row level. Just bind the Javascript methods to the control at the time of databind and the validation events would automatically get triggered.

So you need is, add attributes to the textbox(or other controls), at there onchange/onblur call a JS method. Pass on the value of the control as a parameter too. Now, you have the value, do the validation needed and move ahead if needed.
