XamlParseException on template selector

Posted By:      Posted Date: October 19, 2010    Points: 0   Category :WPF

'Failed to create a 'Type' from the text 'vm:ProcessViewModel'.' Line number '4' and line position '19'.

Anyone know why this is happening?

If I click on ProcessViewModel and press F12 it opens the class.  Wonder why Visual Studio likes it but runtime doesn't.

InfoPath / ActiveX error when using person selector field in Word template off SharePoint document l

I have created an out-of-the-box document library on a SharePoint 2010 site.  I left Microsoft Word Document selected as the Document Template.  I then added a person or group column and a multiple lines of text column to the document library. I then went into Library Settings --> Advanced Settings and clicked on Edit Template, opening the template in Word.  I created my template and added the two new columns to the document.  I did this using the Quick Parts --> Document Property --> [column name] feature under the Insert tab in Word.  I then saved the template back to SharePoint. Upon opening the template or creating a new document from the template, I get the following dialog box: --------------------------- Microsoft Office InfoPath --------------------------- One or more ActiveX controls could not be displayed because either: 1) Your current security settings prohibit running ActiveX controls on this page, or 2) You have blocked a publisher of one of the controls. As a result, the page might not display correctly. --------------------------- OK   --------------------------- I've searched around (I believe fairly extensively) and have not run into anyone else with the same issue.  Some have mentioned a similar error when creating a custom document information panel in InfoPath, and suggested lowered ActiveX security setti

WPF ComboBox Key Index not working when using data template selector


Hi all,

I have a problem regarding WPF combobox when using data template selector.

Basically, WPF combobox has a standard behaviour which will take you directly to the item that starts from a character if you type that character using keyboard. I don't know the official name for this functionality and will temporarily call it "Key Indexing".

I now want to create a ComboBox which displays its item differently. I achieved this using DataTemplateSelector;

        <ComboBox SelectedItem="{Binding Selection}" x:Name="Input" ItemsSource="{Binding Parties}">
                <Editor:PartyTemplateSelector DefaultTemplate="{StaticResource Default}" NewTemplate="{StaticResource New}" OldTemplate="{StaticResource Old}"/>


And the PartyTemplateSelector is:

    public class PartyTemplateSelector : DataTemplateSelector

XML Wrapper Template: Transform XML Documents into Visual Basic Classes


The XML Wrapper template described in this article transforms XML documents into Visual Basic classes, hiding the more complex parts of using the Microsoft XML parser. Developers who have little knowledge of XML or the Microsoft XML parser can use classes created with the template, thus making it easier to use XML in their projects. This article describes the template, shows classes in a sample application based on the template, and explains how to customize those classes to support repeating child elements. Although this project is illustrated using Visual Basic 6.0, the technique can be extended for use with other versions of Visual Basic and with other languages.

RPC and C++: Build a Template Library for Distributed Objects Containing Multiple Interfaces


Building a C++ template library for developing distributed object-oriented applications using Remote Procedure Calls (RPC) allows the programmer to design RPC applications that are composed of components that implement multiple interfaces. This article demonstrates the use of techniques such as assembly-level thunks to build machine code on the fly, and C++ features such as templates, conversion operators, virtual destructors and virtual function tables. Along the way, familiar C++ interfaces and classes are transformed into a distributed application. The benefits of using distributed objects rather than raw remote procedures, which include writing fewer lines of code, is explained.

More Windows 2000 UI Goodies: Extending Explorer Views by Customizing Hypertext Template Files


The Web-style interface is the default Explorer folder view for the Desktop Update in Windows 2000. The Desktop Update uses HTML-based hypertext templates to create the Web view, and you can customize these templates to include your own views and commands. This article shows you how the Explorer Web view works and how to build your own custom templates for it. You'll see how to add a command prompt and task buttons to a new folder view using HTML, script, and ActiveX controls. The shell object model and thumbnail shell extensions are also examined, then used to build a simple icon viewer for Explorer.

jquery datepicker not popping up in Gridview Edit Template textbox


I have a gridview that I can't for the life of me get the datepicker calender to pop up for.  I've been using the datepicker for months very successfully for a variety of textboxes on the page and inside of formviews but this is the first time I've tried using with gridview.  I didn't expect any issues however can't seem to find anything to work.  I have searched the forums for 2 days and attempted any suggestions found within the solutions to no avail.  I've tried using the CSS to link the datepicker but everything stopped working when I changed the code and my page which uses a css style already got all distorted looking.  Please help!

Here is my gridview (only included a part b/c it is large and am only having problem with the datepicker for the date completed text box)

<asp:GridView ID="GridViewCompleted" runat="server" AllowPaging="True" AllowSorting="True"
        AutoGenerateColumns="False" BackColor="#CCCCCC" BorderColor="#999999" BorderStyle="Solid"
        BorderWidth="3px" CellPadding="4" DataKeyNames="job_id" DataSourceID="SourceJobProjectCompleted"

Accounts in Default Template


Hi,  I'm trying to learn in the VS 2010 Express. Using the default template for ASP.Net Website. It starts the web application with an accounts folder. I'm trying to extend the "registration" or "AddUser" utilities. What I'd like to do is modify the registration by adding additional elements (i.e., address, city, ST, zip, etc.). I know I can open the database and modify the Users table and also modify the stored procedure for CreateUser.

My question is:  I don't see any reference in the page code (here's a reprint of the register.aspx.vb) that calls the procedure, or even passes in the variables from the textbox entries from the page. I must be missing something. Can someone clue me how to drill into this template to find the elements like how it communicates with the database. There are a few JQuery files. I am not yet very familiar with JQuery. Is that where I need to look? Thanks for any advice...

Can you hide the "Form Template Conflict" message?


We have 100s of Infopath 2003 forms published on our Sharepoint site (MOSS 2007).  These forms are updated constantly.  The problem we have is that anytime we change the form's design (ex. change wording on the form), the user will get the "Form Template Conflict" message when they click on the form.  This is very confusing to them, and although we've asked them to click on "Replace form", they still get confused.

This message is very confusing to anyone, not just a user.  We would like to suppress this message so that every single time we update a form, they don't have to see this.  I'm not sure why it even saves a copy locally on their machines, anyway.  The fact is that in 100% of all cases, they will need to replace the form on their computer.  Renaming the forms every time we edit them is not an option - there are too many and links would all be broken. 

Can anyone tell us how to "hide" or "suppress" this error for our users?  Or design a form on the back-end that won't show this?  Could possibly changing security settings prevent this?  Any suggestions would be appreciated on how to prevent this message from popping every time we update a form.
