问题 I'm using a modified version of the jQuery UI Autocomplete Combobox, as seen here: http://jqueryui.com/demos/autocomplete/#combobox For the sake of this question, let's say I have exactly that code ^^^ When opening the combobox, either by clicking the button or focusing on the comboboxs text input, there is a large delay before showing the list of items. This delay gets noticeably larger when the select list has more options. This delay doesn't just occur the first time either, it happens

问题 I am creating a ComboBox array dynamically and the DataSource for all the ComboBox is a single integer list that contains some integers. But when I change a value say X in any one combo box then all other combo values get reset to value X. 回答1: Since you are binding all combo boxes to the same data source - a single list - they are using a single BindingManagerBase. So when you choose an item from one of combo boxes, the current Position of the shared binding manager base changes and all

HTML combo box with option to type an entry

问题 I was under the impression you could type into a combo box besides selecting any values already in the list. However, I can't seem to find info on how to do this. Is there a property I need to add to it to allow typing of text? 回答1: Before datalist (see note below), you would supply an additional input element for people to type in their own option. <select name="example"> <option value="A">A</option> <option value="B">A</option> <option value="-">Other</option> </select> <input type="text"

问题 My project is in Visual Basic. I am trying to create a custom & savable "filter" for a DataGridView using several TextBoxes. Right now, any List(Of String) that is added to the Combo Box is displayed in the box as (Collection). I want my users to be able to select the one they created, so I would like the Lists to have a display name that can be selected in the Combo Box. Here is some of the code. Dim savedFilter As New List(Of String) savedFilter.Add(NameTextBox.Text) savedFilter.Add

Add strings to MFC ComboBox

问题 Trying to add strings to ComboBox: BOOL CMyAppDlg::OnInitDialog() { CComboBox *combo= (CComboBox *)GetDlgItem(IDC_COMBO_TT); combo->AddString("s1"); combo->AddString("s2"); // ... return TRUE; } Why ComboBox list is still empty? 回答1: Do you see the first string if you call combo->SetCurSel(0)? If so it means the combo box drop down size is zero. In the visual dialog editor click on the combo's down arrow then drag the bottom edge down to resize the drop down part. 来源: https://stackoverflow

WPF ComboBox bad blank value

问题 I have a WPF ComboBox that binds to a set of data. I do not have permissions to modify the control directly, nor can I change the data. I'm returned 1 item in my ComboBox, but there are actually 2 rows; the blank row and my expected value. Both appear to have an index value of 0. I don't want to see this blank row, just my expected data in the ComboBox auto-selected. I have looked through everyone's related posts in here, but none of the solutions have worked for my case.
