We have a large WinForms app, and there is a built-in bug reporting system that can be activated during testing via the F5 Key. I am capturing the F5 key with .Net's PreFilterMessage system. This works fine on the main forms, modal dialog boxes, etc. Unfortunately, the program also displays windows messageboxes when it needs to. When th...
In a Windows Form, I have a search box that fires an event to search a remote database and display some results. The query is pretty fast, usually just a fraction of a second, but in case the delay is noticeable there is a progress bar and label in the form's status bar. When the user clicks "Search" the status label should appear and th...

So is there some way to do this through...

Hello everybody people, One of the frustrations with the standard TreeView is that you can't show a partial selection to indicate that some of the children are selected.

The datagridview rowsremoved event gets called every time the data gets loaded. It also makes sense to a certain extent that every time the data loads, the existing rows are removed. so technically the event should get called.
