you can do it like: //hide document.getElementById("TextBox1").style.display = "none"; //show document.getElementById("TextBox1").style.display = "block";

I am learning english.I am still having a few problem, but I getting better. I am very glad if you point my mistake in english. TIA.

You can do it with javascript. For example: add the following code on the child page function Test() { var parentTextBox = parent.document.getElementById("TextBox1"); //TextBox1 is the ID of TextBox on ParentPage. alert(parentTextBox.value); } I am learning english

I had written a example for you : function Test(objSource) { for(var i = 0;i< objSource.childNodes.length;i++) { var obj = objSource.childNodes[i]; if(obj.tagName != null && obj.tagName.toLowerCase() == "input" && obj.type.toLowerCase() == "checkbox") { alert(obj.id); } else { Test(obj); } } } //begin get ids of CheckBoxList function GetIDs() { var objSource = document.getElementById("CheckBoxList1"); Test(objSource); } -- modified at 8:34 Monday 13th August, 2007 learning english
