How do I get the form name my controls are in?

[Dale]

Greetings

I am building a composite control that populates a CheckBoxList with values from a database. A HtmlInputText control allows the user to type in the checkbox label value and have it checked in the list. All of the values are 3 characters in length, so I have a client-side onKeyUp checking the length of entry. If it is 3, then I do a postback. What I want to be able to do is have the text selected in the HtmlInputText after the postback. Right now, I am doing that with Page.RegisterStartupScript in my Render event. But I am having to use sScript += "Form1." & _filterText.ClientID & ".select();" to do it. I am concerned that if the developer changes the name of the form from Form1 to something else, that it will break. How do I get the actual form name

Thanks

Dale.

Try doing something like:

document.forms[0]." & _filterText.ClientID & ".select();

That way you just get the first form.

Dale,
I've used code like the following to get the form name, but it relies on the form name being the same as the aspx page name.

private void getFormName()
{
//string formName ;
string[] _path = this.Request.CurrentExecutionFilePath.Split('/');
int count = _path.Length - 1;
string name = _path[count];
this.i_FormName = name.Substring(0, name.LastIndexOf("."));
}

You *could* walk up the control tree until you find an instance of HtmlForm.
