Problems with ListViewItem.FindItemWithT
I have a Listview that because of other processing, I loose track of what was selected. I need to update that selection, so I tried FindItemWithText. It isn't working the way I would expect it to.
The first item in the listview is called BookNbr and has an alphanumeric value. I have verified the value I'm searching for, and it does indeed exist in the first column of the Listview.
Is there something I'm missing or misunderstanding?

ListViewItem lvi = dataBasePanel.FindItemWithText(tbBookNbr.Text); // find the item we were working on...

if you set the "HideSelection" Propertyoft the ListView to "false" the selection is not removed - even if the control looses focus.
I other words: the selection is saved.

here is the full code assuming a listView1 on a Form1 and two Buttons (button1 and button2)
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
AddItems(10);
}
private void AddItems(int counter)
{
for (int i = 0; i < counter; i++)
{
ListViewItem item = new ListViewItem(string.Concat("item", listView1.Items.Count.ToString()));
item.SubItems.Add("1234");
listView1.Items.Add(item);
}
}
private void button1_Click(object sender, EventArgs e)
{
AddItems(1);
}
private void button2_Click(object sender, EventArgs e)
{
if (listView1.SelectedItems.Count > 0)
{
MessageBox.Show(listView1.SelectedItems[0].Text);
}
}
}
