listbox

问题 I don't know how to convert the type for name so that each element in it can be added to my ListBox. If someone could help that would be much appreciated. XDocument doc = XDocument.Load(workingDir + @"\Moduleslist.xml"); var names = doc.Root.Descendants("Module").Elements("Name").Select(b => b.Value); listBox1.Items.AddRange(names); I'm getting an error on AddRange(names) saying invalid arguments 回答1: names is IEnumerable<String> and listBox.Items.AddRange is expecting an object array and

问题 Question: I would like to create a listbox that would appear and disappear below label1 but it should not affect the position of label2, when label1 is clicked. How can this be done? Background: I have written a test code (see below) to show my problem. On 1st mouse click, listbox appears but pushes label2 downwards. On 2nd mouse click, listbox hides but label2 remains in new location and does not return to original position. I have tried using .grid_forget() but got the same behaviour.

问题 I have an ActiveX listbox on an Excel 2007 worksheet. I want to populate it directly, not by pointing its RowSource property to a range, because there is no range that has the desired values. The listbox's ColumnCount is set to 2. I set ColumnWidths to "20;20", and now it returns: 20 pt;20 pt So as far as I understand, two columns in the listbox should be available for writing, right? Populating the first column is no problem: activesheet.lstApplyCurves.List = array("Select All","Deselect All

问题 Hello I am having troubles with my application. I am trying to load a list into listbox1 and then refresh the same list in listbox2 (but with possibly different results) and then compare the two and display in textbox1 the differences between the two list boxes. I have gotten to a point where I am able to tell if there are differences but when it goes to post into the textbox it displays the entire listbox and not the differences. That's a little wordy. Sorry. Below is my code: TextBox1.Text

问题 Is there a way to add some buttons to the selected ListBoxItem by adding these buttons to a style which is being used for the selected item? I didn't yet find a suitable style FMX uses to display the selected item. My goal is to have some buttons on the selected item with context based functionality. While I can do this by reparenting a TButton created in code in the OnPaint event of the ListBox, this works for Android but not for Win32 as it is being overpainted by the selection. Other

问题 I am trying to check that an item doesn't already exist in a list box before I add the new item. if (TeamNameTextBox.Text != "") { if (TeamNameListBox.Items.FindByValue(TeamNameListBox.Text) == null) { TeamNameListBox.Items.Add(TeamNameTextBox.Text); TeamNameTextBox.Text = ""; int teamCountUpdate = TeamNameListBox.Items.Count; if (teamCountUpdate == 1) { TeamCount.Text = teamCountUpdate.ToString() + " Team"; } else { TeamCount.Text = teamCountUpdate.ToString() + " Teams"; } } else {
