The dialog box cannot be manipulated when the modal dialog box is started.

jquery UI Dialog code:

$ (document). Ready (function () {$ ("#dialog"). dialog ({autoOpen:true, AppendTo:"form", Height: -, Width: -, modal:true, buttons: {OK: function () {$ ("#btnCM"). Click (); }, Cancel: function () {$ ( This). Dialog ("Close" );    }            }        }); });

div Code:

<DivID= "Dialog"title= "Choose the practice Plane"><PAlign= "Center"    　　 <Asp:textboxID= "Txta"runat= "Server"></Asp:textbox></P></Div>

Or you can use

$ ("#dialog"). Dialog (). Parent (). AppendTo ($ ("Form:first"));

You can resolve the problem that the backend gets the control value, but not the modal dialog box.
