Finding the previous and next sibling controls

Question

Is there a way to find the previous and next sibling controls in an ASP.net form from code-behind, similar to findControl()?

Sometimes you don\'t want to assign an I

Answer 1

I don't think there is a built in function like that, but it is very easy to extend the Control class and add methods to it like so:

public static Control PreviousControl(this Control control)  
{
   for(int i=0; i<= control.Parent.Controls.Count; i++)
      if(control.Parent.Controls[i].Id == control.Id)
         return control.Parent.Controls[i-1];
}

Of course a bit more handling needs to be done here (if there is no previous control or other scenarios) but i think you get the picture of how this could be done.

After writing this method you can call it like

Control textBox1 = textBox2.PreviousControl();
