Peter,
The Bind() and Eval() functions take an optional format string that can be
used to format the data that is bound to a target property. In your case you
can format the NavigateUrl on a Hyperlink control to be something like
"mailto:ya**@xyz.com". Change your Bind(..) or Eval(..) call to
Bind("Email", "mailto:{0}"). The token {0} in the format string is replaced
the value of "Email" from your SqlDataSource.
Also, binding to SqlDataSource only works with server controls that support
Data Binding (Server controls that have a DataSourceID, such as the GridView,
FormView, DetailsView, DropDownList, CheckBoxList, BulletedList, etc.).
Here is an example of a GridView that has a bound mailto column using a
Hyperlink control.
Hope this helps,
Jason Vermillion
<asp:GridView ID="GridView1" runat="server" DataSourceID="SqlDataSource1"
AutoGenerateColumns="False">
<Columns>
<asp:TemplateField HeaderText="Binding Using a format string">
<ItemTemplate>
<asp:HyperLink ID="lnkEmail" runat="server" NavigateUrl='<%#
Eval("Email", "mailto:{0}") %>' Text='<%# Eval("Email", "Send an Email to
{0}") %>'></asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
Hi,
I want to create a mailto link from data coming from an SQLDataSource. How
do I have to change the following code to get it working? The mailto works,
outlook starts with a new message, but the email address has not been filled
in because I don’t know how to pass the email variable into the mailto
command.
<asp:HyperLink runat="server">
<A href="mailto:">
<asp:Label ID="EmailLabel" runat="server" Text='<%# Bind("Email")
%>'></asp:Label><br />
</asp:Hyperlink>
</A>
Thanks in advance,
Regards,
Peter
