Class Set as DataContext in XAML without Code Behind

In dealing with a problem at work and I am probably as guilty as anyone of relying on code behind to do basic functions without soley using XAML. Why? Because that’s the way I have always done it. But it’s a new day and time to learn new ways to do things. So here we go….

This example shows a class set as datacontext – the code behind file is completely empty.

Have a great week….

C# Application linked to SharePoint List Web Service

This weekend found myself knee deep in a crisis that my friend who had migrated from SharePoint 2003 to 2007 (there were reasons he couldn’t go to 2010). Simply put the migration from SharePoint 2003 to 2007 had broken his application (tracking program that submitted data to a 2003 SharePoint List) because in SharePoint 2007  you can’t do this while not on the actual server if you have “Web Page Security Validation” enabled. So for the code below you have to have SPWeb.AllowUnsafeUpdates = true; . Obviously not the ideal solution for my friend but we didn’t have time to screw around. Here is what I did….

            frmPicture = new TriggerTrackerPictureBox();
            frmPicture.localForm = this;
            frmPicture.Owner = this;
            frmPicture.Show();
            frmPicture.Width = 68;
            frmPicture.Height = 65;
            SetPositionOfPictureForm();
