Pass values from one aspx page textbox to another aspx page textbox

Good day, I need help.

I would like to pass values from one aspx page textbox to another aspx page textbox.

I'm editing the pages & adding code (so no clue what i'm doing) i thought of javascript but no luck on passing the value to the next pages textbox.

On the 1st aspx page textbox1 onclick button go to another aspx page passing the value of the 1st Page Textbox1 = 2nd Page Textbox2

Page1 Apsx
<input type="text" text="Textbox1" id="Textbox1" value="">
<button to call 2 page passing the value>

Page2 Aspx
<input type="text" text="Textbox2" id="Textbox2" value="VALUE OF PAGE1 TEXTBOX1">

Please assist & provide code to send & define the var for second page

Regards
