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

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.

Answer 1

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

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()
