Setting Navigation url to hyperlink dynamically

Question

Im trying to set navigation url to a hyperlink which is inside a gridview.

Im creating the table inside the gridview using a literal in backend c# code.

The code now look like inside GridviewRowDataBound(object sender, GridViewRowEventArgs e)

Literal.Text += "<asp:HyperLink ID='hlContact' runat='server' NavigateUrl='#'>Contact </asp:HyperLink>";

I want to set the navidation inside this code

If anyone have an idea it will be helpful

Thanks

This will just render the text "<asp:HyperLink..." on your page, not actually create a control and add it to viewstate. Bummer, but this approach will never work. — Michael Jasper

You should just create a HyperLink control, instead of trying to add one to a literal:

HyperLink lnk = new HyperLink();
lnk.Text = "Hello World!";
lnk.NavigateUrl = "~/somefolder/somepage.aspx";

e.Row.Cells[0].Controls.Add(lnk);

If your approach can work, you could try something like this:

Literal.Text += String.Format("<asp:HyperLink ID=\"hlContact\" runat=\"server\" NavigateUrl=\"{0}\">Contact</asp:HyperLink>", navigationUrl);

If you want to use a Literal control though, I would do something like this instead:

Literal.Text += String.Format("<a href=\"{0}\">Contact</a>", navigationUrl);

Perhaps I'm misunderstanding the question or context, but won't that simply render "<asp:Hyperlink..." to the response being sent back to the browser? At what point will the aspx page "re-process" the literal's text so that "<asp:Hyperlink..." is rendered as "<a href=..."?

@mikemanne: That was my thought as well, hence my first suggestion to add a HyperLink control to a parent container of some sort.

If you are just trying to simply databind a HyperLink field in a GridView with a bound field, you can use a TemplateField. Here is an example to do it up front and not the hassle of adding it in the code behind.

<asp:TemplateField HeaderText="Contact" SortExpression="LastName, FirstName">
    <ItemTemplate>
        <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# String.Format("~/Page.aspx?ID={0}", Eval("CustID").ToString()) %>'>Contact</asp:HyperLink>)
    </ItemTemplate>
</asp:TemplateField>

When we writing html content to the literal, it won't picking up the asp hyperlink correctly. But when I used the normal “a” tag, it taking the redirection path correctly.

literal.Text += "a ID='linkcontact' runat='server' href='" + "www.website./pagename.aspx?ID=" + id + "'>contact</a>";

Seems you went on a different direction! This is not about creating a menu with navigation. This is a link + some other information inside a grid-view column where data been appended to a literal. Seems you joined the site today. Appreciate your contribution. But have a look at the questions where there aren’t any accepted answers. If answer is accepted you will see a check mark on left to the answer!
