How to get the HtmlForm element of an ASP.NET Page?Hello, All,
I just want to know that generally how to get the HtmlForm element in an ASP.NET Page? Can anybody help? Please:) Best regards, Laser Lu. You need to declare a field in your code behind for the form:
protected System.Web.UI.HtmlControls.HtmlForm Form1; Use Form1 or whatever ID you've assigned to it in the ASPX. -Brock DevelopMentor http://staff.develop.com/ballen Show quoteHide quote > Hello, All, > > I just want to know that generally how to get the HtmlForm element in > an > ASP.NET Page? > Can anybody help?

such a method like FindForm() which is provided in System.Windows.Forms.Control class, as the Form element is specific and unlackable to all ASP.NET Web Forms.

HtmlForm isn't 100% necessary...you can easily have an ASP:Label in a page without a form...there are other controls which don't require a form also, though most functionality does require it. by the way, in the future youshould try to avoid cross-posting to so many newsgroups...

System.Web.UI.Page so you can have some generic methods that you would like. Then I would create a method similar to the one outlined previously with one exception, make the method look for the Controls form... This way you can get the form that a control belongs to since there could be nested forms or multiple forms on a page.

By the way, is it possible to have nested forms or multiple forms on an ASP.NET page?

is a recusive call to step through each Control in the ControlCollection looking for the HtmlForm. public static HtmlForm GetForm( ControlCollection controls ) { HtmlForm form = null; for( int i = 0 ; i < controls.Count ; i++ ) { if ( controls[i] is HtmlForm ) return controls[i] as HtmlForm; if ( controls[i].HasControls() ) { form = GetForm( controls[i].Controls ); if ( form != null ) return form; } return null; } Since the HtmlForm is typically a top level control, performance isn't too terribly bad.

As you said, since the HtmlForm element is typically a top level control, or not-too-deep level control, the algorithm taken for finding the Form element should search horizontally through a topper level first and then its child levels, not deeply search the children first using function recursion.

search. Normally this doesn't matter as the Page.Controls looks like LiteralControl HtmlForm LiteralControl The first literal control will have no children, nor will the third control. So you will take two iterations to find the HtmlForm. bill Show quoteHide quote "Laser Lu" <laser***@hotmail.com> wrote in message news:12441632507960828593750@news.microsoft.com... > Hello William, thank you:) > As you said, since the HtmlForm element is typically a top level control, > or not-too-deep level control, the algorithm taken for finding the Form element > should search horizontally through a topper level first and then its child > levels, not deeply search the children first using function recursion.

Maybe I didn't say it clearly. The object I want to get is of type HtmlForm, which is exactly refer to the HTML <FORM> element in the Web Page, but not the Page object itself. So here, I suppose, it is not 'this' or 'me' in the code behind:) However, thanks for your reply:) Show quoteHide quote > In your code behind, it is "this" or "Me". > > "Laser Lu" <laser***@hotmail.com> wrote in message > news:4904632507054740937500@news.microsoft.com... > >> Hello, All, >> >> I just want to know that generally how to get the HtmlForm element in >> an >> ASP.NET Page? >> Can anybody help?
