Hi,
I need to add the query of the current page to the NavigateURL( which is used in one of the control in the same page). I have to do it on the front end(i.e).aspx page rather than the back end. I have explained a small example of What my requirement is..

Consider I have a Page called "Hello.aspx". This has id="1" as query string

In Hello.aspx
I have a control say HyperLink say helloHyperLink. I have to assign the same query that is in the current page to the NavigateUrl tag eg: NavigateUrl="something("Welcome.aspx")". here the welcome.aspx is called with the same parameters that the Hello.aspx have.

do you want to send a value from the hello page to welcome page?

Solution 1

Have a look at ASP.NETs Request object:

i.e.:

HTML

NavigateUrl='<%=Request.RawUrl%>'

... or to navigate to another page passing the querystring parameters

HTML

NavigateUrl='<%=string.concat("Welcome.aspx?", Request.QueryString)%>'

Hope this helps.

hi.
The solution is not working. It is forming the URL as below

"http://localhost:63994/%3C%=string.concat(%22Window.aspx?%22,Request.QueryString)%20%%3E"

eh, no ... the solution does NOT produce the URL: "http://localhost:63994/%3C%=string.concat(%22Window.aspx?%22,Request.QueryString)%20%%3E"

The script between Embedded Code Block (i.e. - the contents of <% %>) will run, rather than append the text to the NavigateUrl property.

If you don't know how script blocks work, have a read about them here: http://msdn.microsoft.com/en-us/library/ms178135%28v=vs.100%29.ASPX

We can use Javascript for that

Hyperlink to call the javascript can be given as below

<asp:HyperLink ID="hyperLnk" runat="server" Text="click here" NavigateUrl="javascript:openWinNavigateUrl()"></asp:HyperLink>

and the Javascript can be given as

C#

function openWinNavigateUrl() {
            // getting the query string
            var query = document.location.href;

           // Getting the index of required parameter. here I use parameter "id"
            var n = query.indexOf("id");

            //removing the parameter name
            var queryString = query.substring(n + 3, query.length);

            //here I use the querystring to open the new Window
             window.open("Window.aspx?id=" + queryString);
        }
