FindControl issue (does not find the control)

[ptcoder]

Hello everyone.

I have done a lot of reading regarding the recursive issue with FindControl. I have a FormView with an <EditItemTempla te> and all I want to do is add javascript attributes to the form control like this:
smsTxt.Attribut es.Add("onkeydo wn", "backspacerDOWN (this,event);") ;

My goal is to use JavaScript with the ASP.NET controls. I found some code on another forum to do the recursive lookup and here it is:

public static class Utils
{
    public static Control FindControl(this Control root, string id, bool recurse)
    {
        if (!recurse)
        {
            return root.FindControl(id);
        }
        System.Web.UI.Control controlFound;
        if (root != null)
        {
            controlFound = root.FindControl(id);
            if (controlFound != null)
            {
                return controlFound;
            }
            foreach (Control c in root.Controls)
            {
                controlFound = c.FindControl(id, true);
                if (controlFound != null)
                {
                    return controlFound;
                }
            }
        }
        return null;
    }
}
 

I have my code to add the attributes in the Page_Load:

TextBox smsTxt = FormView1.FindControl("SMSTextBox", true) as TextBox;
        if (smsTxt != null)
         {
              smsTxt.Attributes.Add("onkeydown", "backspacerDOWN(this,event);");
              smsTxt.Attributes.Add("onkeyup", "backspacerUP(this,event);");
         }

I am not getting any errors, but it does not add the Attributes to the control. I don't think it is actually finding the Textbox control. I wrapped the new FindControl in a Class because I was getting an error. Not sure if I even did that right. I am pretty new to .NET programming.

Can someone help me with this? I sure appreciate it!!
Thank you all.

If you were getting an error, you should check in to see why you were getting that error, instead of just hiding it.

Have you set a breakpoint and stepped through to see if the control is found?
