Question

我需要使用一组子对网络形式的无效控制。我愿把它变成一个可恢复的阶层。这是我迄今为止所做的:

public class Validation
{
    public static void ApplyInvalidClass(Page page, string className)
    {
        foreach (System.Web.UI.WebControls.BaseValidator bv in page.Validators)
        {
            if (!bv.IsValid)
            {
                Control ctrl = page.FindControl(bv.ControlToValidate);

                if (ctrl != null)
                {
                    if (ctrl is TextBox)
                    {
                        TextBox txt = ctrl as TextBox;
                        txt.CssClass = "invalid";
                    }

                    if (ctrl is DropDownList)
                    {
                        DropDownList ddl = ctrl as DropDownList;
                        ddl.CssClass = "invalid";
                    }

                    if (ctrl is CheckBox)
                    {
                        CheckBox cb = ctrl as CheckBox;
                        cb.CssClass = "invalid";
                    }

                    if (ctrl is HtmlGenericControl)
                    {
                        HtmlGenericControl html = ctrl as HtmlGenericControl;
                        html.Attributes.Add("class", className);
                    }
                }
            }
        }
    }

}

问题是我所说的话。用户控制网,我猜测,因为Im在页面上转过。 FindControl(bv.Control ToValidate)永远无效。

是否有更好的办法这样做?

<代码>Page.FindControl is not recurs, it only search what is direct in the control Collection. 由于你重新搜索的控制权在用户委员会中被宣布无效。

可查阅。 FindControlFunction here。
