Combobox keyup vb.net example1/8/2023 Private Sub ComboBox1_KeyDown(ByVal sender As Object, ByVal e As ) Handles ComboBox1.KeyDownīasically this second solution doesn't have any advantages in itself, but may be useful.Īs I (quickly) tested these, the combobox behaved "normally" (ComboBoxStyle.DropDown). ' Enter-key passes through and will be suppressed in KeyDown event handler Save the text user typed, open url or whatever After PreviewKeyDown event the KeyDown event is raised and you'll suppress Enter-key there Private Sub ComboBox1_PreviewKeyDown(ByVal sender As Object, ByVal e As ) Handles ComboBox1.PreviewKeyDown Second solution is to trap Enter-key in the PreviewKeyDown event handler, do your stuff there and let the Enter-key pass through. ' Do your stuff here (open url or whatever)ĭo your stuff in the event handler itself before suppressing Enter-key. A simple solution Private Sub ComboBox1_KeyDown(ByVal sender As Object, ByVal e As ) Handles ComboBox1.KeyDown IMHO you have two ways to act for the Enter-key. So you can't "disable" Enter-key functionality (user selects from the list and presses Enter-key). It could be that I'm trying to accomplish this the wrong way altogether. Being done with a Class is not a requirement, but was part of a possible solution I thought would be worth working with. Perhaps there is something to that, and I need to modify the Class ClasscboBox.vb? You asked about what code the ComboBox belongs to, which is the main WinForm. They had this sound from the start and obviously need some additional code in order to catch and stop it from happening. I did not think simply removing those lines would make this ding sound vanish as there are two other comboboxes in the project in the main WinForm (Form1) that exhibit the same problem (windows error ding sound) and do not have the solution attached to them. (This and a TreeView are my only two stumbling blocks for this project.) The additional selected item line had since been removed, but is unimportant at this time anyway as I am mainly concerned with the annoying ding sound. ![]() to pass to it though I added a new sub for it.ĭropping those lines did not make the ding go away. Is it possible I need to call this from the SelectedIndexChanged event? This is brought up when pressing the Enter key from the designer. ObjcboBox.KeyDown(objcboBox, New KeyEventArgs(Keys.Enter))Į.Handled = True ' <- This keypress has been handled, no more processing for that ![]() If e.Ke圜ode = Keys.Enter Then ' Enter could be trapped in KeyDown eventĮnd Class Private Sub ComboBox1_KeyDown(ByVal sender As Object, ByVal e As ) Handles ComboBox1.KeyDown Public Shadows Sub KeyDown(ByVal sender As Object, ByVal e As KeyEventArgs) Is this some sort of MS torture tactic? I mean, it shouldn't even be there, or at least should have a property setting for it LOL! Here is the current code again, with first the class and then the routine. Had me goin there, looks good, but still dings :( I'd really appreciate any help on this as I am sure this would be useful to others as well. I have three comboboxes so I though this would best suit my needs in the interests of writting decent code and not populating each call with repeating code. I am a little ahead of my classes (no pun intended) so I am likely missing something about what I am doing wrong. However, it says that KeyPressEventArgs is a Type and cannot be used as an Expression. Looks good, but I am having a problem calling it from the main project. Protected Overrides Sub OnKeyPress(ByVal e As KeyPressEventArgs) ![]() I created a new seperate Class within my Project. There is an annoying DING! when hitting the Enter key in a ComboBox in VB.Net so I sought solutions. I didn't think this would be a problem, but it appears that others also search for this solution.
