VB.NET: How to dynamically select a list view item?

Question

I need to dynamically select an item in a listview based on what was selected previously.

The items that have been selected in the past are retrieved from a database and added to an Arraylist. These items then need to be selected from a number of different listviews.

Doing this by index like so listRef1.Items(2).Checked = True is no problem but I need to do it by the item text, i.e. one of the strings in the array.

So far I have this:

For i As Integer = 0 To refsArr.Count - 1
   'find the correct category id
    Dim cmdRefCat As New SqlCommand("SELECT RefID from ReferencesListTable WHERE            RefName = '" & refsArr(i) & "'", conn)
    Dim refid As Integer = cmdRefCat.ExecuteScalar()
    If refid = 1 Then
        listRef1.Items(refsArr(i)).Checked = True
    ElseIf refid = 2 Then
        listRef2.Items(refsArr(i)).Selected = True
        listRef2.Select()
    ElseIf refid = 3 Then
        listRef3.Items.Item(refsArr(i)).Selected = True
        listRef2.Select()
    ElseIf refid = 4 Then
        listRef4.Items.Item(refsArr(i)).Selected = True
    End If
Next

Has anyone got any ideas on this? Thanks.

You'll need to loop through each item in the listview list:

For I as Integer = 0 to ListView.Items.Count - 1 Do
    If ListView.Items(i).Text = "Text" then
         ListView.Items(i).Selected = true
    End If
End For

You can try this ...

For i As Integer = 0 To refsArr.Count - 1
   'find the correct category id
    Dim cmdRefCat As New SqlCommand("SELECT RefID from ReferencesListTable WHERE            RefName = '" & refsArr(i) & "'", conn)
    Dim refid As Integer = cmdRefCat.ExecuteScalar()
    Select case refid
      case 1 
        CheckIt(refsArr(i),listRef1)
      case 2 
        CheckIt(refsArr(i),listRef2)
      case 3 
        CheckIt(refsArr(i),listRef3)
      case 4
        CheckIt(refsArr(i),listRef4)
    End Select
Next

And Sub CheckIt

Sub CheckIt(ByVal sRef as String, ByRef lvw as Listview)
    Dim x as Integer

    For x = 0 to lvw.Items.Count - 1 
        If lvw.Items(x).Text = sRef then
           lvw.Items(x).Selected = true
           exit for '-- if only 1 record   
        End If
    Next
End Sub

Iterating through both the list view and the array and comparing each did the trick, but this is a nice solution. Thanks! — redned, May 16 '13 at 21:10

The code to select an item dynamically from the listview control can be as follows for vb.net.

Let lvwomominiChair1 is the name of the listview control.
Set its fullrowselect property as true.

The code will select the text in the first column of the listview control.

Private Sub  lvwomominiChair1_Click(sender As Object,e As EventArgs) Handles lvwomominiChair1.Click   
    Dim lvwitem as ListViewItem
    lvwitem = lvwomominiChair1.SelectedItems.Item(0)
    MsgBox("Selected item is  " + lvwitem.Text)
End Sub

There may be situations where we need to get all items in a row of a ListView control.The following code may be used for the purpose.It is assumed that there are five columns of data in a raw and are of the text data type.This can be done with a For..Next loop as follows.Let 0,1,2,3 and 4 are the five column indices.

Private Sub  lvwomominiChair1_Click(sender As Object,e As EventArgs) Handles lvwomominiChair1.Click   
        Dim i As Int32
        Dim str As String
        str =""
        For i =0 To 4
        str = str + " " + lvwomominiChair1.SelectedItems(0).SubItems(i).Text
        Next
        MsgBox("Selected items  of the five columns of the row are " +  str)
End Sub

Or you can do this, works perfect for me:

ListView.Items(0).Selected = True

ListView.Select()
