Part of this works. I have a repeater with a radiobutton and a textbox. If radiobutton is "YES", user has to enter something in the textbox.

I added a CustomValidator and OnServerValidate="test" with ControlToValidate="rbQuestions". I have a server side event for this as well.

For the textbox, i added a RequiredFieldValidator and disabled it.

In the OnServervaidate, I check the Radiobutton value = "Y". So far it all works

But now, when the radiobutton is YES, i dont know how to check for the textbox not being empty. I did below but nothing gets validated.

My repeater and event code are below:
protected void test(Object source, ServerValidateEventArgs args)
    {
        if (args.Value == "Y") //this reads the radiobutton value
        {

            foreach (RepeaterItem item in rpQuestions.Items)
            {
                
                RadioButtonList rbQuestion = (RadioButtonList)item.FindControl("rbQuestions");
                RequiredFieldValidator rfv = (RequiredFieldValidator) item.FindControl("rfvExplain");
                

                    //for (int i = 0; i <= rbQuestion.Items.Count - 1; i++)
                    //{
                    //    if (rbQuestion.Items[i].Value == "Y") //.SelectedItem.
                            rfv.Enabled = true;

                    //    else
                    //        rfv.Enabled = false;
                    //}
            }
        }
    }

Try this:
protected void test(Object source, ServerValidateEventArgs args)
    {
        if (args.Value == "Y") //this reads the radiobutton value
        {

            foreach (RepeaterItem item in rpQuestions.Items)
            {
                
                RadioButtonList rbQuestion = (RadioButtonList)item.FindControl("rbQuestions");
                RequiredFieldValidator rfv = (RequiredFieldValidator) item.FindControl("rfvExplain");
                
                if(rbQuestion != null)
                {
                   if (rbQuestion.SelectedValue == "Y")
                            rfv.Enabled = true;
                       else
