Gridview keep value even move to another page in Gridview?

Question

Hi Friends,

 

I have one gridview in that one textbox control. When adds value to textbox and move to next page of the gridview, its values cleared again I come to previous page. I want to keep all values whichever row is altered in textbox, even though I move to another page of the gridview.

 

How can I achieve that? If anyone know pls suggest me. 

 

Thanking You,
