Hello!
Please, could anyone tell, is it possible to set multiple items to be
selected in list control in the code? For example when the web form is loaded
three items of 5 are selected in list control already? Now I manage to set
only one item to be selected during page load, but there is need to multiple
items could be selected for the user. I appreciate very much your help!
Thanks.

Yes, try this statement before you start selecting the items
'Set Selection mode as Multiple
[YourListBoxID].SelectionMode = ListSelectionMode.Multiple

------------------
<%@ PAGE language="VB" runat="server" %>
<SCRIPT language="vb" runat="server">
Sub Page_Load(Source as Object, E As EventArgs)
'Add Items To List
lbxList.Items.Add("Item 1")
lbxList.Items.Add("Item 2")
lbxList.Items.Add("Item 3")
lbxList.Items.Add("Item 4")
lbxList.Items.Add("Item 5")
lbxList.Items.Add("Item 6")
lbxList.Items.Add("Item 7")
lbxList.Items.Add("Item 8")
lbxList.Items.Add("Item 9")
lbxList.Items.Add("Item 10")
lbxList.Rows = 10
'Set Selection mode as Multiple
lbxList.SelectionMode = ListSelectionMode.Multiple
Dim litmItem as ListItem
' Select every third list item
Dim i As Integer = 0
For Each litmItem In lbxList.Items
If (i + 1) MOD 3 = 0 Then
litmItem.Selected = True
End If
i += 1
Next
End Sub
