validating dynamically generated textbox using regularexpressionvalidator

iam dynamically generating two textboxes on add textbox button which is working fine but i want to validate the value of that textboxes as well but when i apply validation and run the page and click add button nothing happens when i debug the code there is no error and the control executes all the lines but if i comment the validation code then add button works fine see here 

        TextBox addtimeout = new TextBox();
        addtimeout.ID = "addtimeout" + j;
        addtimeout.EnableViewState = true;
        PlaceHolder2.Controls.Add(addtimeout);

        RegularExpressionValidator rev = new RegularExpressionValidator();
        rev.ValidationExpression = "^(1[0-2]|0[1-9]):[0-5][0-9]\040(AM|am|PM|pm)$";
        rev.ControlToValidate = addtimeout.Text;
        rev.ErrorMessage = "Invalid time format. Time format HH:MM AM/PM";
        rev.Enabled = true;
        PlaceHolder2.Controls.Add(rev);

        PlaceHolder2.Controls.Add(new LiteralControl("<br />"));

tell me what i am doing wrong??

UPDATE

rev.ControlToValidate = addtimeout.ID;

still not working.

Generally...IF you make dynamic code for validation than try to add validationGroup property...to make consistant validation...

Control to Validate Requires the Id of your control i.e. but you are passing the text of your text box so to make it work.

Change 

rev.ControlToValidate = addtimeout.Text;

to

rev.ControlToValidate =addtimeout.ID;

Control to Validate Requires the Id of your control i.e. but you are passing the text of your text box
