Represents an item in a ListView control. ListViewSubItem objects specified for each item. The example also creates ColumnHeader objects to display the subitems in details view. Two ImageList objects are also created in the code example to provide images for the ListViewItem objects.
The example uses the following properties in creating the ListView control:. You need to add the code to a Form and call the method created in the example from the constructor or another method on the form. The ListView control is similar to a ListBox in that it displays a list of items.
The main difference is that the ListView control provides a number of different ways items can be viewed by the user. The ListViewItem class defines the appearance, behavior, and data associated with an item that is displayed in the ListView control. ListViewItem objects can be displayed in the ListView control in one of four different views.
Items can be displayed as large or small icons or as small icons in a vertical list. Items can also have subitems that contain information that is related to the parent item. The fourth view style, details view, allows you to display the item and its subitems in a grid with column headers that can be used to identify the information being displayed in a subitem. Most of the properties of the ListViewItem class provide ways to change the display of the item in the ListView control it is associated with.
Items can display check boxes in order to obtain item choices from the user in a way similar to a CheckedListBox control. You can use the Checked property to determine if an item is checked, or to select or clear the check box at run time. Items can display any number of subitems when the View property of the associated ListView control is set to Details and columns are defined in the ListView. ColumnHeaderCollection of the ListView control.
You can add subitems to an item by calling the Add method of the ListViewItem. ListViewSubItemCollection class. ListViewSubItemCollection class and its members. Some of the properties and methods of the ListViewItem class are item-specific versions of properties and methods in the ListView control.
For example, the EnsureVisible method is similar to the ListView version of the method, but the ListViewItem version affects only the current item. The BeginEdit method places the item's text into edit mode so the user can change the item's text when the LabelEdit property of the ListView control is set to true. Initializes a new instance of the ListViewItem class with default values.
Initializes a new instance of the ListViewItem class and assigns it to the specified group. Initializes a new instance of the ListViewItem class with the image index position of the item's icon and an array of ListViewItem.While talking with one of our customers, he wanted an additional feature in one of our programs to let him drop a number of files onto our application and then modify certain properties of the resulting documents in a list.
Showing these documents in a ListView can be done easily, but editing of single properties requires a little work since built-in ListView only allows plain editing of a ListViewItem 's text. Because I didn't find anything pre-built, I decided to write my own in-place editing for ListView s, so here it is In fact, in-place editing in a ListView isn't too much magic, but there are a few places where the plain.
First, you have to have a control to perform the actual editing of the SubItem. Which control you use is almost completely up to you. Since this control is used only when a SubItem has been clicked, it should be invisible in the beginning.
Then you have to find out which SubItem has been clicked.Android Studio : How to Create a Listview with SubItems
A little twist comes from column reordering. Standard ListView allows you to rearrange its columns while in report view AllowColumnReorder property. Unfortunately, there is no built-in way to find out the current order of your columns, so this is where Interop came in handy:. The next step is to move the editor control in place and to make it visible. Once the actual editing is being performed, the user must be able to accept or reject any changes he makes, so there are a few events that have to be caught while editing.
Usually, a click outside the editor control accepts any changes made, as does the Return key. Because the editor control actually is not part of the ListViewI also had to look for any action that might change the size or location of the editor control. This was done overriding WndProc :. Here, scrolling and resizing of the ListView are monitored as well as changes to the ListView 's column headers.
If one of these messages is received, the input focus is transferred back to the ListViewthus ending in-place editing. There are two ways to perform in-place editing with ListViewEx. First, you can use the new SubItemClicked event together with GetSubItemBounds to position your editor control by yourself, or you can use StartEditingwhich performs all required calculations and control positioning by itself.
So, usually you would start by adding a ListViewEx and at least one control used as a cell editor to your Form. Don't forget to make your cell editor control invisible! Then wire up an event handler for SubItemClicked and actually start editing:.
I've included a small sample application to show you how to use ListViewEx with several different cell editors. Feel free to use the control or the source to your heart's desire and have fun! Your comments gave me some hints on missing features, so meanwhile I've added an additional property DoubleClickActivation so that you can decide if the ListViewEx should enter editing mode when you click on a subitem or if a double click is required.

Font property — This property sets the font of the current item. By default, subitems inherit the style of the basic item. Text property — This property indicates the caption of the current item or subitem. To retrieve a specific subitem, use a statement such as the following:. To add a new subitem to the SubItems collection, use the Add method, passing the text of the subitem as an argument:.
The argument of the Add method can also be a ListViewItem object. Create a ListViewItem, populate it, and then add it to the Items collection as shown here:. If you want to add a subitem at a specific location, use the Insert method. The Insert method of the SubItems collection accepts two arguments: the index of the subitem before which the new subitem will be inserted, and a string or ListViewItem to be inserted:.
Like the ListViewItem objects, each subitem can have its own font, which is set with the Font property. The items of the ListView control can be accessed through the Items property, which is a collection. As such, it exposes the standard members of a collection, which are described in the following section. Its item has a SubItems collection that contains all the subitems of the corresponding item.
