On my website, I have two .aspx pages - default1.aspx and default2.aspx. The first page, default1.aspx, contains a textbox named textbox1, while the second page, default2.aspx, contains a textbox named textbox2. default1.aspx opens default2.aspx using the window.showmodaldialog() function. However, I am encountering an issue where changing the text in textbox2 also changes the text in textbox1.
