Hi, An example is already available here: http://www.essentialobjects.com/Demo/Default.aspx?path=SlideMenuThe full source of the sample project is also on your local machine if you installed our controls. Thanks

Hi Saji,
Can you explain specifically how it does not work? We know the sample works. And if your code does not work, you need to tell us exactly how it is not working. Did you get an error message? Or things do not show up at where they suppose to? Just telling us "it does not work" is like going to see your doctor and just telling him "I am sick". There is no way they are going to be able to do anything with you in that case. So we generally do not response such questions unless you provide specific details.
Thanks

Hi,
Please try with a static CustomItem first. Once you get CustomItem working, you can switch to dynamic CustomItem and then also put a Label or something else in your CustomItem, that way you will know whether it's CustomItem not created correctly or TreeView not populated correctly. Also try to create CustomItem in Page_Init instead of Page_Load or any other event handler. Dynamically created controls generally should be created at early stage of the page.
Thanks

Yes thanks for your support, finally it got worked
The problem is: customitem is not generating dynamically. so i created static custom item controls as many as required, then created treeview dynamically and assigned to the custom control object dynamically.
then added the custom control to the slidemenu.
is there any solution to create the custom controls dynamically??
the code i am posting below: some one can use
' dynamic custom item creation not working
Dim tvObject As New EO.Web.TreeView
tvObject.ID = "MyTv_" & parentID
tvObject.TopGroup.Style.CssText = "background-image:url('00030417');background-repeat:repeat-y;border-bottom-color:#999999;border-bottom-style:solid;border-bottom-width:1px;border-left-color:#999999;border-left-style:solid;border-left-width:1px;border-right-color:#999999;border-right-style:solid;border-right-width:1px;border-top-color:#999999;border-top-style:solid;border-top-width:1px;color:black;cursor:hand;font-family:Tahoma;font-size:11px;padding-bottom:2px;padding-left:2px;padding-right:2px;padding-top:2px;"
Dim rootNode As New EO.Web.TreeNode
rootNode.Text = "Root"
Dim row As DataRow
For Each row In Ds.Tables("tblResult").Rows
Dim tvNode As New EO.Web.TreeNode
tvNode.DisabledStyle.CssText = "background-color:transparent;border-bottom-style:none;border-left-style:none;border-right-style:none;border-top-style:none;color:Gray;padding-bottom:1px;padding-left:1px;padding-right:1px;padding-top:1px;"
tvNode.NormalStyle.CssText = "padding-right: 1px; padding-left: 1px; padding-bottom: 1px; color: black; border-top-style: none; padding-top: 1px; border-right-style: none; border-left-style: none; background-color: transparent; border-bottom-style: none"
tvNode.SelectedStyle.CssText = "background-color:Silver;border-bottom-color:#999999;border-bottom-style:solid;border-bottom-width:1px;border-left-color:#999999;border-left-style:solid;border-left-width:1px;border-right-color:#999999;border-right-style:solid;border-right-width:1px;border-top-color:#999999;border-top-style:solid;border-top-width:1px;color:white;padding-bottom:0px;padding-left:0px;padding-right:0px;padding-top:0px;"
tvNode.Text = row.Item("menu_caption") & ""
tvNode.NavigateUrl = row.Item("menu_url") & ""
tvNode.ToolTip = row.Item("tooltip") & ""
tvNode.ImageUrl = row.Item("icon_url") & ""
If row.Item("target") & "" <> "" Then tvNode.TargetWindow = row.Item("target") & ""
RootNode.ChildNodes.Add(tvNode)
Next
tvObject.Nodes.Add(RootNode)
Ds.Clear()
Ds = Nothing
' Five custom items created statically
' CustomerItem1, CustomerItem2 ....CustomerItem5
' Parent Id starts with 100,200 ... 500
' find the statically created control
Dim customItem As EO.Web.CustomItem
customItem = CType(Me.FindControl("CustomItem" & Left(parentID.ToString, 1)), EO.Web.CustomItem)
customItem.Controls.Add(tvObject)
' add the tree menu to SubItem
Dim sItem1 As New EO.Web.MenuItem
sItem1.CustomItemID = customItem.ID
' Add the subitem to the main menu item
mItem.SubMenu.Items.Add(sItem1)
