Simplify it by placing the code in a function

<script>
        function openWindow() {
            var pid = document.getElementById('<%=txt_voucher.ClientID %>');
            var chdate = document.getElementById('<%=txtbox_chqdate.ClientID %>');
            var pname = document.getElementById('<%=txtbox_chprovider.ClientID %>');
            window.open("Product.aspx?pid=" + pid + "chdate= " + chdate + " & pname= " + pname + ", null,scrollbars=yes,top=10,left=10", "true");
        }
    </script>

<asp:ImageButton ID="ibut_cheque2" runat="server" target="_blank" OnClientClick='openWindow()' AlternateText="Print" CssClass="btn5" ForeColor="White" ToolTip="Print Cheque" />

While doing it I am getting an error "The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>)."Can you please help me

place the script before the end of body tag
reference [^]

Product.aspx?cid=[object%20HTMLInputElement]chdate=%20[object%20HTMLInputElement]%20&%20pname=%20[object%20HTMLInputElement],%20null,scrollbars=yes,top=10,left=10

The values is passed like this .ie I think the variables are not getting textbox values.

Karthik_Mahalingam 15-Nov-17 23:02pm

Oh My mistake, forget to add the value property
should be

function openWindow() {
            var pid = document.getElementById('<%=txt_voucher.ClientID %>').value;
            var chdate = document.getElementById('<%=txtbox_chqdate.ClientID %>').value;
            var pname = document.getElementById('<%=txtbox_chprovider.ClientID %>').value;
