The following code example creates a ListView control with three ListViewItem objects specified and three ListViewItem.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. These ImageList objects are added to the LargeImageList and SmallImageList properties. The example uses the following properties in creating the ListView control:
Using the ListViewItem.ListViewSubItemCollection, you can add subitems, remove subitems, and obtain a count of subitems. For more information on the tasks that can be performed with the subitems in the collection, see the ListViewItem.ListViewSubItemCollection class reference topics.
C Listview Subitems
The first subitem in the ListViewItem.ListViewSubItemCollection is always the item that owns the subitems. When performing operations on subitems in the collection, be sure to reference index position 1 instead of 0 to make changes to the first subitem.
The Windows Forms ListView control can display additional text, or subitems, for each item in the Details view. The first column displays the item text, for example an employee number. The second, third, and subsequent columns display the first, second, and subsequent associated subitems.
Add any columns needed. Because the first column will display the item's Text property, you need one more column than there are subitems. For more information on adding columns, see How to: Add Columns to the Windows Forms ListView Control.

This example explains an easy way to edit ListView subitems. A double click on the ListView.SubItem will visualize a TextBoxoverlaying the SubItem with same size. The entered signs will be written to the SubItem after TextBox_LostFocus event was raised(by clicking on the ListView control or hit RETURN key).
If you do not want to have a uniform background color, foreground color, and font used for all items and subitems in your ListView control, you can set this property to false. When this property is set to true, any changes made to the subitem's ListViewItem.ListViewSubItem.Font, ListViewItem.ListViewSubItem.ForeColor, and ListViewItem.ListViewSubItem.BackColor properties are ignored, and the values of the item are used instead. You can use this property if you need to specify a different text color, background color, or font to be used for a subitem to highlight the item when subitems are displayed in the ListView control.
I have legacy 'C' code that I'm trying to port to win32++, just keep running into roadblocks at every turn.The latest is trying to find an easy way to control colors for every aspect of a listview. Searched the web,but all the solutions too complicated or don't work. I just can't have the text color or background in a singlecolor which is the default. Any help would be appreciated.
Trying to click on a listview row, highlight it and go off and do other processing.The NM_CLICK and NM_DBLCLK below return the row that I want to Highlight only if youclick in column 0, any other column returns a -1. I know I have a problem with theSendMessage function, appreciate all the help.
The method sets num_rows equal to the number of items in the ListView control's Items collection. It then loops through that collection to see which item has the most sub-items.Note that an item's SubItems collection includes the item, too. For example, suppose the ListView control named lvw has a first item that includes the values Apple, Banana, and Cherry. Then lvw.Items[0].Text is Apple and lvw.Items[0].SubItems contains all three values Apple, Banana, and Cherry.When it loops through the SubItems collection, the program keeps track of the SubItems collection that has the most items. that gives the number of columns we need in the array.Having found the number of rows and columns it needs, the program allocates the results array. It then loops through the items again, this time copying the ListView data into the array. When it is done, the method returns the result.Using the extension method is easy. The following code shows how the main program uses the method when you click the Get Data button.// Get the ListView's contents.private void btnGetData_Click(object sender, EventArgs e) // Get the contents. string[,] listview_data = lvwBooks.GetListViewData(); // Display the contents. StringBuilder sb = new StringBuilder(); int num_rows = listview_data.GetUpperBound(0) + 1; int num_cols = listview_data.GetUpperBound(1) + 1; for (int r = 0; r
The SelectedItem is simply the current selected item in the listview. Be aware that more than one item can be selected if multi-selections are allowed. A listview has ListItems (Each individual 'line'). The ListItem.Text is the first column. This is what is referred to when you use .SelectedItem.Text. Each ListItem has SubItems corresponding to the number of column and these are numbered 1, 2, 3.... Every listitem has the same number of subitems. I should have said I don't use Listviews with VBA as some users here have a full install and some don't, so I only use the basic intrinsic controls in VBA. You can refer to controls on another user form by specifying the userform name ibefore the textbox control name...UserForm99.TextBox99.text = userform87.listview56.selecteditem.text
Although I may not have worked it out in the best coding fashion. I still got my code to work. I have a listview with 8 columns (0 - 8) and I needed any rows that has "True" as text in column 8 to turn red.
I have another row color problem. The below code searches the listview and finds the row with a blue select high light. What I'm trying to do is make the row it finds green in color. I tried a lot of code to get this to work, but no go. It's much the same as lvi.UseItemStyleForSubItems = False and lvi.SubItems(1).ForeColor = Color.Red" but isn't working for me.
Once COSMOS is launched in your browser, click the plus button on the top left corner. Once you click the plus, you will see a dropdown menu which contains: Import Data, Import RSS Feed and Start Twitter Collection subitems. To import pre-existing data on COSMOS:
Within our Helloworlds model we need to include our image information within the SQL query. However, because this image information is JSON-encoded it's not going to be possible to order by any of the subitems via a SQL ORDER BY clause, so we'll not provide functionality to sort by the equivalent image column in the display, and so there's no need to add any fields to the filter-fields array. 2ff7e9595c
