. Introduction This article describes how to implement ListView with image on subitems. It's very useful in programs that need to show the status of several items.
OAKListView control This class inherits from the ListView class. Using the code Make some change in your code. Add a traditional ListView control to your form and make the changes (in black) as below: /./ /// /// Summary description for Form1. /// public class Form1: System.Windows.Forms.Form // Change this line. Private System.Windows.Forms.ListView listView1; private System.Windows.Forms.ColumnHeader columnHeader1; private System.Windows.Forms.ColumnHeader columnHeader2; /// /// Summary description for Form1. /// public class Form1: System.Windows.Forms.Form // Like this line. Private OAKControls.OAKListView listView1; private System.Windows.Forms.ColumnHeader columnHeader1; private System.Windows.Forms.ColumnHeader columnHeader2; /./ /./ #region Windows Form Designer generated code /// /// Required method for Designer support - do not modify /// the contents of this method with the code editor.
ListView?: WPF with VIsual Studio 2010. You have to add subitems to your ListViewItem: ListViewItem item = new ListViewItem(); item.
/// private void InitializeComponent this.components = new System.ComponentModel.Container; System.Resources.ResourceManager resources = new System.Resources.ResourceManager( typeof(Form1)); // Change this line. This.listView1 = new System.Windows.Forms.ListView; #region Windows Form Designer generated code /// /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// private void InitializeComponent this.components = new System.ComponentModel.Container; System.Resources.ResourceManager resources = new System.Resources.ResourceManager( typeof(Form1)); // Like this line. This.listView1 = new OAKControls.OAKListView; /./ Changing image on subitem OAKListView.LVITEM lvi = new OAKListView.LVITEM; // Row of the item lvi.iItem = 5; // Column of the item lvi.iSubItem = 5; lvi.pszText = ' OAKListView-' + I.ToString; // Here you pass the mask of the item. In this case // the mask is the both, Image and the text lvi.mask = OAKListView.LVIFIMAGE OAKListView.LVIFTEXT; // Image index on imagelist lvi.iImage = 1; // Sending a message to make the changes OAKListView.SendMessage(listView1.Handle, OAKListView.LVMSETITEM, 0, ref lvi); Conclusion Most of the functionalities have been described here. I do not guarantee that this control works 100%. If you find mistakes, you can correct them.
This control is not a final release and you can send me mails with explanations if you find bugs or mistakes, and join the modifications if you did them. Jasonmf 6-Mar-11 21:23 6-Mar-11 21:23 declared numbers of 'LVSEX.' But used only 5. I tried to just pass 'LVSEXSUBITEMIMAGES ' to 'lParam': Message.Create(this.Handle, LVMGETEXTENDEDLISTVIEWSTYLE, IntPtr.Zero, (IntPtr)LVSEXSUBITEMIMAGES); It can run also.
If I just pass 'LVSEXSUBITEMIMAGES ' to Message's Create Method, the listview wehther will has any problem? What meaning each of these Constant? The values can be custom? Bs9999 30-Nov-06 5:15 30-Nov-06 5:15 I have the class added to my own but it doesn’t appear to be showing any icons for subitems.
I noticed that if I have the Visual Studio.Net 2003 designer attach an image list to the Oak List View then absolutely no icons are shown, not even within column 0. However if I remove this and manually insert the listview – imagelist association within the FormLoad then the column 0 icon appears however still no subitem icons appear. Im using.Net Framework 1.1 on VS Studio.Net 2003 C# Very odd. Was wondering if there was some subtle pattern I was missing.

. The Width and Height properties represent the width and the height of a ListView. The Name property represents the name of the control, which is a unique identifier of a control. The Margin property tells the location of a ListView on the parent control. The HorizontalAlignment and VerticalAlignment properties are used to set horizontal and vertical alignments. The following code snippet sets the name, height, and width of a ListView control. The code also sets horizontal alignment to left and vertical alignment to top.

The new ListView looks like Figure 4. Formatted ListView Displaying Images in a ListView We can put any controls inside a ListViewItem such as an image and text. To display an image side by side some text, I simply put an Image and TextBlock control within a StackPanel. The Image.Source property takes the name of the image you would like to display in the Image control and TextBlock.Text property takes a string that you would like to display in the TextBlock.
The following code snippet adds an image and text to a ListViewItem. I change the code of ListViewItems and add following CheckBoxes to the items. As you may see, I have set the name of the CheckBoxes using Name property.
If you need to access these CheckBoxes, you may access them in the code using their Name property. Now, the new ListView looks like Figure 6.
