Hi amitsinghr,

Refer the below Script code for your reference for how to show selected Item text of dropdown also the textbox box value in alert box.

<script type="text/javascript">
    function Confirm() {
        var confirm_value = document.createElement("INPUT");
        confirm_value.type = "hidden";
        confirm_value.name = "confirm_value";

        var ddlRoomNo = document.getElementById('<%= ddlRoomNo.ClientID %>');
        var ddlRoomNoSelectedText = ddlRoomNo.options[ddlRoomNo.selectedIndex].innerHTML;    
        
        var ddlRoomStatus = document.getElementById('<%= ddlRoomStatus.ClientID %>');
        var ddlRoomStatusSelectedText = ddlRoomStatus.options[ddlRoomStatus.selectedIndex].innerHTML;

        var txtDepartureDate = document.getElementById('<%= txtDepartureDate.ClientID %>');
        var txtDepartureDateText = txtDepartureDate.value;        

        if (confirm("Do you want to Checkout \n Room No :- " + ddlRoomNoSelectedText + " \n Room Status :- " + ddlRoomStatusSelectedText + " \n Departure Date :- " +txtDepartureDateText)) {
            confirm_value.value = "Yes";
            document.forms[0].appendChild(confirm_value);
        }
        else {
            confirm_value.value = "No";
            document.forms[0].appendChild(confirm_value);
        }
    }
</script>

<script type="text/javascript"> function Confirm() { var confirm_value = document.createElement("INPUT"); confirm_value.type = "hidden"; confirm_value.name = "confirm_value"; var dropRoomNo = document.getElementById('<%=ddlRoomNo.ClientID %>').options[document.getElementById('<%=ddlRoomNo.ClientID %>').selectedIndex].text; var dropRoomStatus = document.getElementById('<%=ddlRoomStatus.ClientID %>').options[document.getElementById('<%=ddlRoomStatus.ClientID %>').selectedIndex].text; var departureDate = document.getElementById('<%=txtDepartureDate.ClientID %>').value; if (confirm("Do you want to Checkout \n Room No :-" + dropRoomNo + "\n Room Status :- " + dropRoomStatus + " \n Departure Date :- " + departureDate+"")) { confirm_value.value = "Yes"; document.forms[0].appendChild(confirm_value); } else { confirm_value.value = "No"; document.forms[0].appendChild(confirm_value); } }

</script>
