I am having issues setting the event handler for the itemcreated and itemdatabound events. I get a compile error of 'trvAssignedTo_ItemCreated' is not a member of the project. But the onNeedDataSource works fine.

<body>

<form id="form1" runat="server">

<div>

<telerik:RadScriptManager ID="RadScriptManager1" Runat="server">

</telerik:RadScriptManager>

<telerik:RadTreeList ID="trvAssignedTo" runat="server" ParentDataKeyNames="ParentID" DataKeyNames="CampusID" OnItemCreated="trvAssignedTo_ItemCreated" OnItemDataBound="trvAssignedTo_ItemDataBound" onNeedDataSource="trvAssignedTo_NeedDataSource" AutoGenerateColumns="false" NoRecordsText="Not Subscribed to Groups">

<Columns>

<telerik:TreeListBoundColumn DataField="CampusName" UniqueName="Campus" HeaderText="Campus" />

<telerik:TreeListBoundColumn DataField="Department" UniqueName="Department" HeaderText="Department" />

<telerik:TreeListBoundColumn DataField="Description" UniqueName="Group" HeaderText="Group" />

</Columns>

</telerik:RadTreeList>

</div>

</form>

</body>

Private Sub trvAssignedTo_ItemCreated(sender As Object, e As TreeListItemCreatedEventArgs)

If TypeOf e.Item Is TreeListHeaderItem Then

If csSession.sessionCompanyType = "L" Then

Dim item As TreeListHeaderItem = TryCast(e.Item, TreeListHeaderItem)

item("Campus").Text = "League"

item("Department").Text = "Division"

item("Group").Text = "Team"

End If

End Sub

Private Sub trvAssignedTo_ItemDataBound(sender As Object, e As TreeListItemDataBoundEventArgs)

If TypeOf e.Item Is TreeListDataItem Then

Dim item As TreeListDataItem = TryCast(e.Item, TreeListDataItem)

If Not DataBinder.Eval(item.DataItem, "ParentID") Is System.DBNull.Value Then

item("Campus").Font.Italic = True

End If

End Sub

Protected Sub trvAssignedTo_NeedDataSource(ByVal source As Object, ByVal e As TreeListNeedDataSourceEventArgs)

Dim dt As DataTable = csSubscribers.getSubscriberGroups(2)

trvAssignedTo.DataSource = dt

End Sub

Hi Tina,

Attached to this message is a sample runnable project where the ItemCreated event fires without problems. Check it out and see what is the difference in your case.

I hope this helps.
