relative url in hyperlinkfield

Question

User996453919 posted

Hi

I am using a grid view inside a web user control. The gridview contains a hyperlinkfield.
I use this control in 3 separate directories within the application.

Directory structure 

appRoot
    Controls -> this folder contains web user control
    folder1
       UserView.aspx ->page uses control
       Process.aspx
    folder2
       Default.aspx ->page uses control
       Process.aspx
    folder3
       New.aspx -> page uses control
       Process.aspx
      

How do I get relative url(s) for the hyperlink fields?

 
If I try to built
Case 1:DataNavigateUrlFormatString="~/Process.aspx?commandid={0}", it takes the approot for relative url, So the url is http://approot/Process.aspx?commandid=5GO53DS3BB.
Case 2:DataNavigateUrlFormatString="Process.aspx?commandid={0}", it takes control folder for relative url, So the url is http://approot/Controls/Process.aspx?commandid=5GO53DS3BB

In any case, the url I require is
http://approot/folder1/Process.aspx?commandid=5GO53DS3BB, or http://approot/folder2/Process.aspx?commandid=5GO53DS3BB or http://approot/folder3/Process.aspx?commandid=5GO53DS3BB when invoked from the respective folder.

Could you state your issue another way? I don't understand your problem

You can use Request.Path, which returns the virtual path of the currently executing aspx (including page name). But you have to use them from code-behind as in: GridView1.DataNavigateUrlFormatString = Request.Path + "?commandID={0}";

 Try using ResolveUrl

Ok drocco, I will explain again.

I have a web user control (let us call it ProcessControl.ascx).  ProcessControl.ascx contains a gridview. The grid view has a databound hyperlink field which call Process.aspx.
The ProcessControl.ascx is used in 3 aspx pages(UserView.aspx,Default.aspx,New.aspx) within different folder.

Let us go to the directory stucture

appRoot
    Controls -> this folder contains web user control
       ProcessControl.ascx
    folder1
       UserView.aspx ->page uses control
       Process.aspx
    folder2
       Default.aspx ->page uses control
       Process.aspx
    folder3
       New.aspx -> page uses control
       Process.aspx
 

 When I use ProcessControl.ascx in UserView.aspx in "folder1", the hyperlink field should point to Process.aspx inside folder1.
 When I use ProcessControl.ascx in Default.aspx in "folder2", the hyperlink field should point to Process.aspx inside folder2.
 When I use ProcessControl.ascx in New.aspx in "folder3", the hyperlink field should point to Process.aspx inside folder3.

 In a single sentence the the hyperlink should take relative url of the aspx page which uses the control.

Hope I am clear.

I had a feeling that is what you meant but wasn't sure

For something like this I would use Server.MapPath

For example a link to your page you could = Server.MapPath("/folder1/Process.aspx") that will take you from the root, to "folder1" to that web page inside folder1

Do the same for the others

I am aware of server.mappath, but this grid view is in a control, which is reused across pages as I mentioned in my post. So I cant hard code folder names.

ResolveUrl looks like it can get the work done. I havnt checked is out in my code yet.

But I am looking for something which can be used declaratively. As these urls are in grid view. If not I have to change for each row data.

Anyway I can use ResolveUrl with asp:Hyperlinkflied tag?

I tried this:
<asp:HyperLinkField DataNavigateUrlFields="Id" NavigateUrl="<%ResolveClientUrl("~/Process.aspx")%>" HeaderText="Process"  DataNavigateUrlFormatString="?commandid={0}" DataTextField="CmdName" /> 

But gives error

VB.Net 

<asp:HyperLinkField DataNavigateUrlFields="Id"

NavigateUrl="<%#  Eval("Process", ResolveClientUrl("~/Process.aspx") & "?CmdName={0}")%>"

HeaderText="Process"  DataTextField="CmdName" /> 

C#:

<asp:HyperLinkField DataNavigateUrlFields="Id"

NavigateUrl="<%#  Eval("Process", ResolveClientUrl("~/Process.aspx") + "?CmdName={0}")%>"

HeaderText="Process"  DataTextField="CmdName" />

Sorry..the last post was made for templatefield with asp:Hyperlink.

You can use this:

 <asp:HyperLinkField DataNavigateUrlFields="FirstName"
                DataNavigateUrlFormatString="?id={0}" DataTextField="FirstName"
                NavigateUrl="<%# ResolveClientUrl("~/Default.aspx") %>" />

Just replace firstname with your column name and id with your query parameter name.

The reasaon NavigateUrl="<%# .. works and not "<%=.." is that they are parsed at different stages. <%= is not allowed in a server controls tag. <%# is if the control is for gridview or any other databound control.

Hi HeartattacK

ResolveClientUrl does not work. I tried to get it to work the other day but no success.

Have you used this in before successfully?

User-1179452826 posted

Why don't you just do this:

<asp:HyperLinkField DataNavigateUrlFields="FirstName"
                DataNavigateUrlFormatString="Process.aspx?cmdid={0}" DataTextField="FirstName"
                />

This will link to the Process.aspx int he same folder as the UserView.aspx page. Change firstname to your db column name.

 Server.MapPath will never works here, it will returns the physical path of the mapped file  !

Please remove the HyperLinkField , and instead use a HyperLink  with a TemplateField ( since you want to resolve the Process.aspx with respect to the page location , use the page.ResolveUrl instead of the User Control ResolveUrl )

 

<asp:TemplateField>
    <ItemTemplate>
        <asp:HyperLink NavigateUrl='<%#  Eval("Id", Page.ResolveUrl("Process.aspx") & "?CmdName={0}")%>'
            Text="Details" />
    </ItemTemplate>
</asp:TemplateField>
