My combobox reverts to unselected, some time later thanks to the currencyManager. The databinding for the SelectedValue does not fire its parse event, the setter for the current object's bound property never fires. There are several other properties bound to the same bindingSource for their value that work. The comboBox below it, which...

I am looking for a decent replacement for the standard windows YES/NO or YES/NO/CANCEL MessageBox. I have often seen these standard dialogs misused in ways such as: "To save in plain text answer YES, or to save in html answer NO". Obviously, the text should read "Save As: and the "buttons should be labeled "Text" and "HTML". It is not...
I am using a DataRepeater to show data from a business objects on the screen. I am using windows forms in C# to accomplish this. The datasource is not available at compile time so I want to bind the datasource at runtime. Here is the simplified scenario. I'm using this business class: public class Product { private double _price; ...
I have a TreeView with ItemHeight=16 and CheckBoxes=true. I want to show images that are 8x16 pixels in size on the nodes. But when I do this, the "Plus/Minus" and "CheckBoxes" change their size (get smaller). How can I fix this? I don't want to use a 16x16 image because I don't want to loose those 8 pixels with white space. Any sugges...
I've created quite a few user controls to encapsulate GUI functionality used in multiple places in my app. I've noticed I usually have a tendency to describe the function of the control and tack "Control" on the end of the name, but not always. I'd like to standardize the naming and wanted to know if there's a best practice for naming Us...
I have a BindingList<> of objects, set to the DataSource of a BindingSource. This is set to the DataSource of a DataGridView. I'm concerned with not causing any potential memory leaks, so wondering if there is a preferred way to unbind these connections when I am finished with the data. I'm thinking of: datagridview.DataSource = null;...
Does anyone know of a good component (C# WinForms) which would allow creating an options (settings) form, given a custom class with a bunch of properties? I am not looking for something shiny, but something merely better than a property grid. I can easily take care of the visual part, but I simply don't want to lose time doing reflection...

I have a control extending PropertyGrid which allows users to set the properties of some of my program objects. These objects have an event which is raised when one of their properties changes, and the PropertyGrid subscribes to this event so that it refreshes itself when a property is changed. My problem occurs when large numbers of obj...
The Windows Forms ComboBox control only offers partial find-as-you-type functionality - it only searches for the first letter. For example if you type "c" and "a", don't expect "California" to become selected - instead you'll land on a state starting with "a". Somehow, perhaps through Firefox, I got used to being able to find items by t...
Hello, I am writing an application that I am working on a skinning feature to it. What I want to do is allow a user to create an XML document that my code will parse through and set properties of the controls on a form. This is the easy part. Where I am stuck is giving the user a way to find out the control names/types with minimal ...
We are developing a rather large Windows Forms application. In several customers' computers it often crashes with OutOfMemory exception. After obtaining full memory dump of the application moments after the exception (clrdump invoked from UnhandledException handler) I analyzed it with ".NET Memory Profiler" and windbg. The Memory Profil...

My WinForms application has a TextBox that I'm using as a log file. I'm appending text without the form flickering using TextBox.AppendText(string);, however when I try to purge old text (as the control's .Text property reaches the .MaxLength limit), I get awful flicker. The code I'm using is as follows: public static void AddTextToCo...
