hello, i have 5 checkboxes in the form, i want to do something like this:
foreach (control c in this.Cotrols) { if (c.GetType.ToString() == "System.Forms.CheckBox") { MessageBox.Show("anything"); } }the problem is: if the checkboxes are inside a panel, ou a groupbox, i cant verify if exists checkboxes in the form... what i can do to find the checboxes that are inside de panel/groupbox? thanks a lot -

If you know the checkboxes are in a group or on a panel, all you have to do is look in the Controls collection of that container control. Also, don't EVER convert the type name to a string and compare it to what you think the full type name should be. You'll just end up writing code where you can't fathom what wrong with it.

Recurse the controls as a tree. Call seekCheck pasing the form as first control. private void seekCheck (Control B) { foreach(Control Con in B.Controls) { if(Con.Controls != null) //is a container { seekCheck (Con); } else { if(Con id CheckBox) { MessageBox ("....."); } } } }

You don't want to do a string compare here. What you want is:
if (c.GetType() == typeof(System.Forms.CheckBox);Ian

CheckBox cb = c as CheckBox;
if(cb!=null)A recursive method would check the "Controls" property of the Control instance c.
RecursiveMethod(this.Controls);
private void RecursiveMethod(ControlsCollection cc)
{
if(cc!=null)
{
foreach(Control c in cc)
{
CheckBox cb = c as CheckBox;
if(cb!=null)
{
//Do stuff
}
else
{
RecursiveMethod(c.Controls);
}
}
}
}Hope it helps! All the best, Martin

no no, just if (c is CheckBox) ... :)
