how to find a control exist in the form?

[nirmalsingh]

hai all i am generating list box dynamically in a form.

 ListBox li = new ListBox();
                             myForm.Controls.Add(li);
                             li.Name ="SearchName";
                             System.Drawing.Point Location = new Point(TextBoxTop-60,TextBoxLeft +30);
                             System.Drawing.Size size = new Size(200, 72);
                             li.BringToFront();
                             li.Location = Location;
                             li.Size = size;
                             li.Visible = true;
 

now before creating a list box , i want to verify that whether a listbox already exist in the form.
thanx in advance

Unless you know the ID of the listbox you are looking for you'll need to loop through all the controls on the page and test each one to see if it's a listbox.

Form.ControlCollection fc = new Form.ControlCollection(form1);

fc.Contains(urlstbox);

the above line will return true if your urlstbox control exsists in ur form or else it'll return false.

hope it'll help u...
