Mail merge images not being displayed

Hello,
I've created a mail merge application as per he example on your website.

The Word document is loaded in, and the docprovider is set. I then insert images fine using insert>picture and they show up in the document. Everything appears fine form within the program.

When I send the emails however, the pictures don't show up. From within Outlook I get an error that reads:

"the linked image cannot be displayed. The file may have been moved, renamed, or deleted. Verify that the link points to the correct file and location."

I've attached a screenshot of exactly how I'm inserting the image into the document. Below is the code I use when I send the emails. Also noteworthy, I had to change the formatprovider from docx to rtf before sending the emails. If I use the docxformatprovider, the text in the email shows up with a bunch of symbols, improperly formatted.

Here's DocOpened event I use when opening and loading the word doc:

try

{

OpenFileDialog fDialog = (OpenFileDialog)sender;

switch (System.IO.Path.GetExtension(fDialog.FileName))

{

case ".docx":

docProvider = new DocxFormatProvider();

break;

case ".rtf":

docProvider = new RtfFormatProvider();

break;

case ".txt":

docProvider = new TxtFormatProvider();

break;

case ".html":

docProvider = new HtmlFormatProvider();

break;

default:

break;

}

using (FileStream fStream = new FileStream(fDialog.FileName, FileMode.OpenOrCreate, FileAccess.ReadWrite))

{

rDoc = docProvider.Import(fStream);

}

rDoc.LayoutMode = DocumentLayoutMode.Paged;

emailForm1.Document = rDoc;

}

...and then when sending the emails I use this.

protected void SubmitEmail(object sender, RoutedEventArgs e)

{

    MailMessage message = new MailMessage();

    byte[] emailBytes = null;

    string bodyText = string.Empty;



    SmtpClient mailServer = new SmtpClient("mail.pentegra.com");

    mailServer.UseDefaultCredentials = true;



    this.emailForm1.Document.MailMergeDataSource.ItemsSource = mergeFields;

    //here's where I change the formatprovider from docx to rtf. if I use docx, the email text comes out as a bunch of   symbols

    docProvider = new RtfFormatProvider();

    //this is just a datatable with a list of emails that gets iterated through to send the emails.

    for (int i = 0; i < _dtMerge.Rows.Count; i++)

    {

        message = new MailMessage();

        foreach (string s in lstAttachments)

        {

            message.Attachments.Add(new Attachment(s));

        }

        message.From = _fromAddress;

        emailForm1.Document.MailMergeDataSource.MoveToIndex(i);

        emailBytes = docProvider.Export(emailForm1.Document.MailMergeCurrentRecord());

        //I convert the byte array into the email body test here.

        StringBuilder sb = new StringBuilder();

        using (StreamReader sReader = new StreamReader(mStream))

         {

                    while (!(sReader.EndOfStream))

                    {

                        sb.Append(sReader.ReadLine() + Environment.NewLine);

                    }

          }

         bodyText = sb.ToString();

        message.AlternateViews.Add(AlternateView.CreateAlternateViewFromString(bodyText, null, "text/html"));



        message.To.Clear();

        message.To.Add(new MailAddress("x@xx.com"));

       mailServer.Send(message);



}

Everything shows up fine in the emails except the image.

Directional navigation & selection

It appears the default behavior when selecting a time is by mouse click only. Can I select via enter key?
I have the following requirement:

- the time picker control shall enable selection of time by pressing Enter key

Before I start intercepting key press events etc., I just want to make sure there are not setter properties I could be unaware of which would enable this behavior.

Thanks in advance.

ScatterSplineSeries

We are looking to change our charting products and I chose to use the ChartView over the older RadChart for the speed and the better customization options, but I am finding some things missing. The big thing is I need a chart with linear X & Y axis, smoothing (spline type is typically what I would use), and ability for marked zones. I have read several other posts concerning some of these and saying they would be available in the upcoming release (Q2 2012), but I am unable to find these.

Am I missing something or are these features not yet implemented?

Also, I watched the webinar over Q2 2012 Xaml controls and saw a mention of new RadChartView features, but I heard nothing about them. Is there any updated documentation with whats new in RadChartView for Q2 2012.

Thanks for your help and continue the good work,
Ryan

Binding RadDocumentPanes to a collection

We are trying to bind a collection of items to a set of RadDocumentPanes through the ItemsSource & SelectedItem properties on the RadPaneGroup control. Unfortunately we were unable to create viable documents in this manner, and had to create a custom converter to return our items wrapped as RadDocumentPanes. Is this a limitation of the Rad control or is there a better way to do this?

Removing Windows Form Controls?

In the attached file it shows the original Windows control bar (that has the minimize, maximize, close) still remains on the RadRibbonView. Also, there is a forward and back navigation bar, I'm not sure why; so, how can I remove these and place the buttons on the ApplicationName bar? Source Code:

<telerik:RadRibbonView x:Class="Magnetek.Network.Client.MainWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

xmlns:ribbon="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.RibbonView"

MinHeight="100" MinWidth="200"

x:Name="RadRibbonWindow">

</telerik:RadRibbonView>

Also, with Windows Ribbon control I can start my window in a certain position using:

WindowStartupLocation="CenterScreen"

Is there a way to set the startup location and start the application maximized?

[Solved] Delay when using EntityFrameworkDataSource

Hello!

In our WPF project, we have a UserControl with a RadGridView to display persons. We decided to use the EntityFrameworkDataSource because it is easy to implement and offers a lot of advantages.

We implement the Entity Data Source and everything is working except one thing. When we click on the Menu to call the UserControl, a delay is occuring. the UserControl takes 5~10 seconds to appear, and when it appear the RadGridView is already loaded with the data.

If i remove the lines of the DataSource, the UserControl loads fast with 2 seconds. The Gridview only has 20 itens, i'm afraid that when the data begins to grow this delay became worse, it will impact a lot for the client.

Can you help me solving this? It is hard to explain with words, if you not understand the problem let me know and i try to make a video.

Thanks!
