Hi, I loaded a custom DataTable into an UltraChart of type GanttChart. The data loads succesfully. Do you know if it possible to add support for mouse resize(drag) to the tasks that show up into the chart? I have not been able to figure out if this is supported by the Infragistics control. Thank you in advance for your answers. Dragos...
Hi, I'd love to know if there is such thing as a Gecko.NET ;) I mean, just like we can embed a WebView and that is an "instance" of IE7 inside any Windows Forms application (and tell it to "navigateto (fancy_url);", I'd love to use FireFox or WebKit. Anybody tried this? UPDATE: Please bear in mind that although it is possible to embed...
When creating scrollable user controls with .NET and WinForms I have repeatedly encountered situations where, for example, a vertical scrollbar pops up, overlapping the control's content, causing a horizontal scrollbar to also be needed. Ideally the content would shrink just a bit to make room for the vertical scrollbar. My current sol...
I have an extender (IExtenderProvider) which extends certain types of controls with additional properties. For one of these properties, I have written a UITypeEditor. So far, all works just fine. The extender also has a couple of properties itself, which I am trying to use as a sort of default for the UITypeEditor. What I want to do ...
In our project, SharpWired, we're trying to create a download component similar to the download windows in Firefox or Safari.

Is there an easy way to ensure that after a drag-and-drop fails to complete, the MouseUp event isn't eaten up and ignored by the framework? I have found a blog post describing one mechanism, but it involves a good deal of manual bookkeeping, including status flags, MouseMove events, manual "mouse leave" checking, etc. all of which I wou...

In a VB.NET WinForms project I get an exception "Cannot access a disposed object" when closing a form. It occurs very rarely and I cannot recreate it on demand. The stack trace looks like this: Cannot access a disposed object. Object name: 'dbiSchedule'. at System.Windows.Forms.Control.CreateHandle() at System.Windows.Forms.Control.get_...
I'm developing a WinForms application (.Net 3.5, no WPF) where I want to be able to display foreign key lookups in a databound DataGridView. An example of the sort of relationship is that I have a table of OrderLines. Orderlines have a foreign key relationship to Products and Products in turn have a foreign key relationship to Product...

[We have a Windows Forms database front-end application that, among other things, can be used as a CMS; clients create the structure, fill it, and then use a ASP.NET WebForms-based site to present the results to publicly on the Web. For added flexibility, they are sometimes forced to input actual HTML markup right into a text field, whic...
The "Open" button on the open file dialog used in certain windows applications includes a dropdown arrow with a list of additional options -- namely "Open with..". I haven't seen this in every windows application, so you may have to try a few to get it, but SQL Server Management Studio and Visual Studio 2005 will both show the button ...
A number of forms in my project inherit from a base form. It is easy to get at the Controls collection of the derived forms, but I have not found a simple way to access the Components collection, since VS marks this as private. I assume this could be done with reflection, but I'm not really sure how best to go about it, not having work...

I'm working on a visual studio 2005 vb.net windows forms project that's been around for several years. It's full of default textboxes, labels, dropdowns, datagrids, datetime pickers -- all the standard stuff. The end result is a very gray, old-looking project. What would be the best approach to making this project look fresh and snazz...

Is there a simple way to format numbers in a Winforms 1.1 datagrid? The Format property of the DataGridTextBoxColumn seems to be completely ignored. I know there is a solution that involves subclassing a Column control, and it's fairly simple, but was hoping there might be some trick to making the Format property just work. Thanks Mik...
