• .NET Development Populating A Combobox

  Well, what should be a simple task is turning out to be a nightmare. I have a simple combobox on my form. I have a simple database with a table in it and some data. All I want to do is populate this combobox, but nothing works. I setup a dataset, the bindingsource, and tableadapter, in preview data comes back, but when the project is run the combo box is always empty.

• .NET Development Master Templates / Themes in User Controls?

  I was surprised recently to discover that neither Master page templates or Themes can be applied to User Controls. Short of porting these to Custom Controls (where I should be able to apply themes, at least) or overriding the Control class does anyone know of any options for working around this My firm's production department often uses User Controls for quick reusable snippets across client web sites since they can easily be created by people with limited development knowlege. Currently we skin these using XML/XLS, CSS or a slough of design properties. This method works but there are various benefits to master pages (in particular) and th ...Show All

• Windows Forms Grid and BindingSource object change

  I was working thru an excellant example by Robert Green of Microsoft entitled Walkthrough: Smart Client Data in Visual Basic 2005.  This was for Visual Studio 2005 beta 1.  Using beta 2 there seems to be a significant change.  When I worked thru this example the DataConnector object has been replaced with a BindingSource object.  Why is this and how do I implement the one to many form using this new object   You are correct in that this has changed and we are working on updating the sample.  Rather than use the "Add related..." smart tag, you can now do this more naturally ...Show All
