using findcontrol to find a control within a literalcontrol

i have a custom control that renders a number of literalcontrols in the createchildcontrols method. as below (there are other lines of literalcontrols being added that i have not uncluded here)

this.Controls.Add(new LiteralControl(string.Format("<input type=\"text\" style=\"display:none\" value=\"{0}\" id=\"{1}\" name=\"{1}\" />", MediaId.ToString(), this.UniqueID)));

i am t开发者_如何学运维hen trying to validate this textbox via adding the [ValidationProperty("myprop")] at the top of the class. basically i need to validate against the value entered into the textbox. the myprop property is as follows

public string myprop
    {
        get
        {
            Control ctrl = this.FindControl(this.UniqueID);
            string txt = ((TextBox)ctrl).Text;

            try
            {
                MediaId = Convert.ToInt32(txt);
            }
            catch { MediaId = 0; }
            return txt;
        }
    }

unfortunately the findcontrol does not find the textbox at all, i presume because as far as .net is concerned its a literalcontrol, not a textbox at all

now for sure i could change the createchildcontrols to do this

        TextBox tb = new TextBox();
        tb.Text = this.MediaId.ToString();
        tb.ID = this.UniqueID;
        this.Controls.Add(tb);

but because of other limitations of what i am doing i would have to change a great deal more stuff in other places..

is there anyway of getting findcontrol to find the textbox rendered inside the literal, or another method?

thanks

That is correct. You have to use some other control like a textbox.
