Hi,

try like this,

C#

TextBox txt = (TextBox)childForm1.ParentForm.Controls["txtbox1"];
// txtbox1 ID or name of textbox
// childForm1 is the object of the child form
if(txt !=null)
{
   MessageBox.Show(txt.Text.Trim());
}

hope it helps.

maybe this is good way :
make a property in child form as parent;

C#

private ParentForm parent;
public ParentForm Parent
{
get{return parent;}
set{parent=value}
}

well you have parent form object as a member of your child form whith this property.
then use this code in parent form:

C#

ChildForm child=new ChildForm();
child.Parent=this;
child.Show();

with this , you have access to parent form members in your child form!
hope help !
