in a asp.net page, i have 1 drop down list and another is gridview.
In gridview, there is a link button which used for navigation to another page using QueryString.
Now Suppose i want to send DropDown value in postbackUrl of Linkbutton, how can we do that without codebehind.

Ex:

XML

<asp:DropDownList ID="ddlVl" runat="server"  
            </asp:DropDownList>

XML

<asp:GridView ID="gvdetails" runat="server" AutoGenerateColumns="false" DataKeyNames="" EmptyDataText="Data Not Present" HeaderStyle-BackColor="Green" HeaderStyle-Font-Bold="true" HeaderStyle-ForeColor="White"  ShowHeader="true" ShowHeaderWhenEmpty="true" Width="100%"  >
                               <RowStyle HorizontalAlign="Center" />
                               <AlternatingRowStyle HorizontalAlign="Center" />
                               <Columns>

XML

<asp:TemplateField HeaderText="Remain">
                                       <ItemTemplate>
                                           <asp:LinkButton ID="lnk" runat="server" OnClientClick="window.document.forms[0].target='_blank';" PostBackUrl='<%# "~/abc.aspx?ddlvalue="  %></asp:LinkButton>

                                       </ItemTemplate>
                                   </asp:TemplateField>

I want to send ddlVl value to abc page via PostbackURl.

SQL

onclientclick call a script function to get dropdown selected value and use
window.location = '/pagename.aspx?value=' + ddlvalue;

thx for reply, one question.

can we directly attach the drop down value to url without any script like:
PostBackUrl='<%# "~/abc.aspx?ddlvalue="+ddlV1.selectedvalue.text %>.
i tried this but it is not working.

i am asking this because in case if there might be more than one link button and in some link button you want to send dropdown value and in some case you don't want to,
if i go via script then i need to put if else condition.

So if there is a direct way then i can directly handle that thing in postbackurl.

how can you attach the value to url without getting dropdown selected value?

OnClientClick="return Navigate()"

<script type="text/javascript">
function Navigate() {
var ddlVal= document.getElementById('dropdownID').value;
window.location = '/pagename.aspx?value=' + ddlVal;
}
</script>
