Define model popup exact after defining image button and textbox in gridview only.
Design popup and keep it in panel,E.g Panel1. Define one lable in this Panel only like this. asp:label id=\"Label1\" runat=\"server\" Text=\"\"
Targetcontrolid=Imagebutton from gridview
Popupcontrolid=Panel1
CancelControlID=\"Label1\"
Now on popup submit button click,
{
//Write your code to assign value
Modelpopup.Hide();
}

when you press imagebutton you can show your modal, and store the entered item in one hidden field or viewstate object or directly into that particular textbox, since ModalPopUp control is available in same page you can maintain like that also, refer below link for your reference.
