Tag Replacement

[Guest]

Hi

I am using List View control to add few records(listview items) . I want to associate some data to each of the list view item or record that I add. It is very easy to do in normal C# by using Tag method. But unluckily Tag method is not supported in Compact Framework. Is there any replacement for the Tag method or is there any work around to do so

Please help
Thanks a lot

Use a ListViewItem that has the "tag" you want as part of it's class. The
items can be any object.

Hi Chris

Can you please elaborate more on this? May be with an example. Also how can I retrieve any Tagged info after I get the item ListItem Click event

Thanks a ton Chris

This is untested, but should give you the idea:

class MyTagItem : ListViewItem
{
private string m_tag;

public MyTagItem(string item, string tag) : base(item)
{
m_tag = tag;
}

public string Tag
{
get { return m_tag; }
set { m_tag = value; }
}
}

listView1.Items.Add(new MyTagItem("Item Text 1", "Item Tag 1"));
listView1.Items.Add(new MyTagItem("Item Text 2", "Item Tag 2"));
listView1.Items.Add(new MyTagItem("Item Text 3", "Item Tag 3"));
listView1.Click += new EventHandler(listView1_Click);

private void listView1_Click(object sender, EventArgs e)
{
MessageBox.Show(((MyTagItem)listView1.SelectedItems[0]).Tag);
}


P.S. If it works, please let me know and I'll add it to the OpenNETCF Wiki.
