combobox

问题 I'm coding an app in MSVS 2008, which has a ComboBox control which I initialize thru the code as below: static char* OptionString[4] = {"Opt1", "Opt2", "Opt3", "Opt4"}; BOOL CMyAppDlg::OnInitDialog() { CDialog::OnInitDialog(); // Set the icon for this dialog. The framework does this automatically // when the application's main window is not a dialog SetIcon(m_hIcon, TRUE); // Set big icon SetIcon(m_hIcon, FALSE); // Set small icon // TODO: Add extra initialization here m_Option.AddString

问题 I have a small problem that has been annoying me for some hours. In my WinForms (.NET 3.5) application I create some ComboBoxes (DropDownStyle = DropDown) in a TableLayoutPanel at runtime and fill it with strings. The ComboBoxes are configured to resize automatically (Anchor = Left | Right). The problem is that whenever the ComboBoxes are resized (i.e. the dialog is resized), the editbox portion of the ComboBox gets selected/highlighted entirely. In my opinion this creates a very confusing

问题 I've stumbled on an issue with Comboboxes in javafx2.2. This is the scenario: Users click on the 'editFile' button. Another pane becomes visible (with the setVisible method). This pane contains 6 comboboxes. Three of them have fixed items: cboReport, cboSales, cboSend. Three of them get their data from a db (ObservableList) and get populated when the pane becomes visible: cboFile, cboCustomer, cboVet The user selects a file number from the cboFile. The rest of the comboboxes are beeing set

问题 I have ComboBox control(WinForm project). When I bind DataSource to the ComboBox control combobox_selectedindexchanged event is fired. Any idea how to prevent selectedindexchanged event when DataSource is bound? 回答1: Remove the handler for the SelectedIndex_Changed event, bind your data, then add the handler back. Following is a simple example of how this might be done within a method: private void LoadYourComboBox() { this.comboBox1.SelectedIndexChanged -= new EventHandler(comboBox1

问题 My jQuery UI AutoComplete ComboBox doesn't have a scrollbar on the right side and gets very, unfortuantely, long as shown below. I'd like to restrain this list to a reasonable length - any thoughts on how that might be accomplished? Thanks! 回答1: You can set the height via CSS: .ui-autocomplete { max-height: 600px; overflow-y: auto; /* prevent horizontal scrollbar */ overflow-x: hidden; /* add padding to account for vertical scrollbar */ z-index:1000 !important; } 回答2: This is an old question,

问题 I have a workbook with several comboboxes (and listboxes) and a lot of vba written around them. I've used the same code in the Workbook_Open procedure to format them for weeks, without any major trouble. Last night I remoted-desktopped in to my work computer (for the 2nd time ever) to edit some other parts of the code (nothing that touched the box properties at all). At one point after a while, the formatting of all the boxes, list and combo, went crazy. The right side scroll bars on the list

问题 I have a ComboBox where a user can select what JobType they are working on. The ComboBox has a list of AllJobTypes. The problem stems from when a user adds a new JobType, I add the JobType to the AllJobTypes ObservableCollection, then sort it. When the sorting happens the ComboBox get's de-selected and not really sure why. The JobConfig.SelectedJobType.Name never changes in this process. Is there a way to sort an observable collection where it doesn't break the ComboBox? public class

问题 I have a DataGrid that two of its columns are ComboBoxes (one contains few but not this is the problem). I want, that when the user changes the first Combo's value, the ComboBox in the other column should bind to a property of its (this property is a collection). Say the First ComboBox is Category, I want that when the user changes its value, the other CB is populated with the values of (first combo's selected category).Vendors. How should I do it, I don't use MVVM, just simple WPF. I don't

问题 I'd trying to style my ComboBoxes to match the rest of the UI but I'm having problems with the IsMouseOver highlighting. It highlights with the color I specify for a second and then fades back to the default color, kind of a cool effect but not what I'm going for. Here is my style: <Style TargetType="ComboBox"> <Style.Triggers> <Trigger Property="ComboBox.IsMouseOver" Value="True"> <Setter Property = "Background" Value="Red"/> </Trigger> </Style.Triggers> </Style> What can I do to make the
