推荐答案

库玛，
这是我所做的并且正在起作用:
1)我创建了一个TextBox
2)我还动态创建了一个必需的字段验证器，并设置了
将ControlToValidate属性设置为上面创建的TextBox的ID.
3)我已经在div中添加了文本框和必填字段验证器，div在aspx页面中.

Hi Kumar,
This is what I have done and it is working:
1) I have created a TextBox
2) I have created a required field validator also dynamically and set the
ControlToValidate property to the ID of the above created TextBox.
3) I have added both text box and required field validator to a div, div is there in the aspx page.

TextBox txt = new TextBox();
txt.ID = "DynControl";

RequiredFieldValidator rfv = new RequiredFieldValidator();
rfv.ErrorMessage = "Error is for Dynamic Control";
rfv.BorderColor = Color.Red;
rfv.ControlToValidate = "DynControl";

divTest.Controls.Add(txt);//This is the div i spoke about in 3rd point
divTest.Controls.Add(rfv);  

4)我在页面上保留了一个按钮，然后在该按钮上单击
必需的字段验证正在触发

希望这对您解决问题有帮助.

4) I kept a button in the page and on this button click,
Required field validation is firing

I hope this will help you in resolving your issue.
