[Solved] GridViewDynamicHyperlinkColumn "mailto:{0}" opens new browser window

[Vassili King]

Hello,

I've been trying to replicate (in a way) the functionality demonstrated on Telerik's web site: http://demos.telerik.com/silverlight/#GridView/ColumnTypes.

They (Telerik) have a mailto link in the grid defined in the following way:

                <telerik:GridViewDynamicHyperlinkColumn DataMemberBinding="{Binding FirstName}" Header="Send e-mail to:" NavigateUrlFormatString="mailto:{0}.{1}@yourdomain.com?subject=Your subject&amp;body=Your text"
                                                         NavigateUrlMemberPaths="FirstName,LastName" TargetName="_blank">
                    <telerik:GridViewDynamicHyperlinkColumn.CellTemplate>
                        <DataTemplate>
                            <StackPanel Orientation="Horizontal">
                                <TextBlock Text="e-mail: " />
                                <TextBlock Text="{Binding FirstName}" />
                                <TextBlock Text="." />
                                <TextBlock Text="{Binding LastName}" />
                                <TextBlock Text="@yourdomain.com" />
                            </StackPanel>
                        </DataTemplate>
                    </telerik:GridViewDynamicHyperlinkColumn.CellTemplate>
                </telerik:GridViewDynamicHyperlinkColumn>

In the demo, once you click the hyperlink, the new email template is opened (if you have a default mail program installed such as Outlook).  When I'm doing the same thing in my grid, the email template also opens fine, BUT a new browser window pops up and stays there.  Telerik's version does not have the popup window (at least i didn't see it).  How do I prevent the window from poping up?

I've tried a couple of different ways, both have the popup...

#1:
                        <telerik:GridViewDynamicHyperlinkColumn DataMemberBinding="{Binding Email}" Header="Email" NavigateUrlFormatString="mailto:{0}"
                                                                NavigateUrlMemberPaths="Email" TargetName="_blank">
                            <telerik:GridViewDynamicHyperlinkColumn.CellTemplate>
                                <DataTemplate>
                                    <StackPanel Orientation="Horizontal">
                                        <TextBlock Text="e-mail: " />
                                        <TextBlock Text="{Binding Email}" />
                                    </StackPanel>
                                </DataTemplate>
                            </telerik:GridViewDynamicHyperlinkColumn.CellTemplate>
                        </telerik:GridViewDynamicHyperlinkColumn>

#2:
                        <telerik:GridViewDynamicHyperlinkColumn DataMemberBinding="{Binding Email}" Header="" NavigateUrlFormatString="mailto:{0}"
                                                                NavigateUrlMemberPaths="Email" TargetName="_blank">
                            <telerik:GridViewDynamicHyperlinkColumn.CellTemplate>
                                <DataTemplate>
                                    <Image Source="images/email_small.jpg" ToolTipService.ToolTip="Click to send and Email."/>
                                </DataTemplate>
                            </telerik:GridViewDynamicHyperlinkColumn.CellTemplate>
                        </telerik:GridViewDynamicHyperlinkColumn>


Thank you!

Hello,

 We do not have any code that opens popup windows. What is your email client and default browser? 

Greetings,

I'm with you on this one, Vlad.  Your demo does not open any popups.  However, once I use the (pretty much) same code in my project, clicking on the hyperlink does open a new browser window with mailto:[e-mail] in the address bar, and then the default mail client is launched.  Both (your example and my project) are ran in the same OS build:  Windows 7, IE 8, Outlook 2010.  I'm using Q2 of the Telerik Silverlight controls.  This is weird that two projects with basically the same code result in different behavior.  Yours is what I'm trying to achieve.

Thank you!

We are also experiencing this issue. It appears to be related to the Enable Protected Mode option in Internet Explorer security settings. This explains why the Telerik web site example works perfectly but running locally, or on an intranet site, brings up the extra window.  Any assistance would be appreciated.
