How to use Eval / Bind to create a mailto link?

[Nahom Tijnam]

Hi,

In my gridview or datalist control, I know how to use the Eval or Bind
method to bind a control property to a data as follows:
<asp:HyperLink ID="email" runat="server" NavigateUrl='<%# Eval("email",
"mailto:{0}") %>'>Email me</asp:HyperLink>
would give result as <a href="mailto:[email protected]">Email me</a>

But is it possible to get a mailto output as below?
<a href="mailto:[email protected]?subject=contact Us">Email me</a>

Here, the difference is that I am trying to bind 2 different data values to
the same property of the control, one for the response email address, and
another for the subject.
mailto:<email from db>?subject=<category from db>

Is this possible, and how could this be done?

Thanks in advance.

Hi Nahom,

Although GridView supports multi-parameters in its HyperLinkField, it's for
Hyperlink rather than for mailto link. You need use GridView_RowDataBound
event to build mailto link like follows:

if (e.Row.RowType == DataControlRowType.DataRow)
{
DataRowView drv = e.Row.DataItem as DataRowView;
HyperLink link = e.Row.Cells[link_field_index].Controls[0] as
HyperLink;
link.NavigateUrl = "mailto:" + drv["mail_address"].ToString() +
"?subject=" + drv["subject"].ToString();
}

Thanks for Elton's good suggestion.

Hi Elton,

For your scenario that we need advanced customization on the hyperlink
control's column, I'd suggest you consider using Template Column(field),
thus, we can either use the RowDataBound event to find the control and set
the property or fields we want (as Elton has demonstrated....) or define a
helper function in page class and use it in Data Bound template (aspx )
inline. e.g:

<asp:HyperLink ID="email" runat="server" NavigateUrl='<%# HelperFunc(
Container.DataItem) %>'>Email me</asp:HyperLink>


HelperFunc is a helper function defined in page class which accept the
databound item and return a string to represent the url string....

Hope also helps. Thanks,

Wondering if you can help me.

I am using mailto in a URL. Basically I want the URL to open outlook --
this is working fine. However I want the email created to include my outlook
signature, but when I use mailto I get a blank email even though I have
signatures turned on. Any ideas on how I can get the signature into the email.

Thanks

 

[Scott M.]

You can't.

 

[Scott M.]

Let me clarify...

The mailto: protocol of a link does not specify that Outlook should open.
It specifies that the browser should open *whatever* email program the
browser has its default set to. Even if Outlook is that program, you may
notice that when you click the link a new mail message is created by Outlook
itself does not open. Because of this order, the signature won't be added.

If you absolutely need this functionality, you should move away from the
client-side mailto: and change your code to server-side code that automates
Outlook.

client-side mailto: and change your code to server-side code that

But the user is on the client side, how can serve-side automation help?

 

[Scott M.]

The mail message does not have to originate at the client. Whoever said it
had to? The application could provide a web based form for the user to fill
out and when the user is done, that client-data can be used to populate a
server generated mail message.

From the way the OP was written, it seems that just one particular signature
is needed on the outbound message.

In other words, you suggest the user will store the signature on the server
and pay for this by not being able to use his Outlook.

No, I am not quite saying that. I am saying that it seems like the OP wants
a specific signature to be used in all cases by his app (in outher words not
a "user" signature, but an "application" signature). So, using server-side
code to retrieve this signature (yes, stored on the server) and generate and
send the email could accomplish this.

If I am wrong and the OP wants individual users to be able to automatically
get their (different) Outlook signatures attached to different messages,
then my original comments (that you can't even count on all users using
Outlook in the first place) apply.

In other words, you suggest the user will store the signature on the
server and pay for this by not being able to use his Outlook.

You say it yourself. The server code will be the one who will generate and
send email, not the client-side Outlook. So the user will not be able to use
his familiar Outlook, rather he will have to rely on what the server-side
program provides.
