Searching for text in a listview control

[bjwade62]

I have two listviews. lvwA and lvwB. I'd like to search lvwB for the existence of the same item in lvwA. I'm not sure how to go about it.

 

Any help? Thanks.

Initially I was going to say you could use the Contains method of the Items collection however upon a quick test that didn't seem to work. One way of doing it would be something like this...

		private void cmdSearch_Click(object sender, System.EventArgs e)
	{
		if(lvwA.SelectedItems.Count!=0)
		{
			string searchText = lvwA.SelectedItems[0].Text;
			bool found = FindItem(searchText);
		}
	}

	private bool FindItem(string searchText)
	{
		for(int i = 0; i < lvwB.Items.Count; i++)
		{
			if(lvwB.Items[i].Text == searchText)
			{
				return true;
			}
		}
		
		return false;
	}

Sorry. I should have been more specific. I'm using VB in VS2005.

Private Function FindItems(ByVal searchText As String) As Boolean
       For i As Single = 0 To i < lvwB.Items.Count
           If (lvwB.Items(i).Text = searchText) Then
               Return True
           End If
       Next
       Return False
   End Function

   Private Sub cmdSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
       If (lvwA.SelectedItems.Count <> 0) Then
           Dim searchText As String = lvwA.SelectedItems(0).Text
           Dim found As Boolean = FindItems(searchText)
       End If
   End Sub

Wow. Excellent. Thank you so much. Works great. Now I'll have to break it down to learn from what you did. Thanks again!
