Let me try to explain my question. I have a menu like this: Menu1 Submenu1_1 Submenu1_2 Submenu1_3 Submenu1_4 Menu2 Submenu2_1 Submenu2_2 Submenu2_3 Menu3 Submenu3_1 I have my menu in a master page file using ASP.NET 2.0 . I want that if the user click on Subbemenu1_2 that submenu stays Expanded. Setting the Expanded option from the menu builder works fine but I can't do this by program. I tried this but it doesn't appear to work as expected
Code:
Protected Sub Menu1_ItemClick(ByVal sender As System.Object, ByVal e As EO.Web.NavigationItemEventArgs) Handles Menu1.ItemClick
If e.MenuItem.ItemID = "QSMision" Then
e.MenuItem.Expanded = True
Response.Redirect("QSMision.aspx")
ElseIf e.MenuItem.ItemID = "SERVCentrodeVentas" Then
e.MenuItem.Expanded = True
Response.Redirect("SERVCentrodeVentas.aspx")
End If
End Sub

Hi,
Take a lot of SaveStateCrossPages property. When you are redirecting to another page, everything is start over, even if use the same master page.
Thanks

Besides setting the SaveStateCrossPages to True is the approach I am using in my code shown above the right way to do what I want to achieve or should I better use the NavigateUrl Property ?

Yes. You should use NavigateUrl. SaveStateCrossPages works with NavigateUrl by default.

Is there any sample showing to do what I want ? I spend quite some time trying different options such as using KeepExpandedOnClick="True" for the menu; Expanded="True" for all submenues; using the ItemClick on the server side, etc. but couldn't figure out the right way.

Hi,
Are you using slide menu? Both Expanded and KeepExpandedOnClick are for menu, not slide menu. For slide menu you should rely on Selected an related property (for example, AutoSelectSource).
In any case, you should avoid "coding" it at all. Just let the slide menu to expand/collapse for you by itself. If you give top level item NavigateUrl (that is, you want clicking a top level item to both expand the pane and also navigate to another page), you will need to set AutoSelectSource to NavigateUrl. Please refer to help file for more details.
Thanks

I am not using the Slide Menu. I tried specifiying Expanded="true" for each menu; indeed it keeps the submenu expanded but the one which is expanded is the last one and not the one I clicked. See below I clicked on "Mision" but the expanded menu is the one under "Enlaces"  I then removed the "Expanded=true" in Enlaces and clicked once again in "Mision" and the expanded menu is under "Informaciones" which is now the last menu with that option

Hi,
That's another reason why you should avoid setting Expanded by code. When you set Expanded by code, whatever you've set is remembered. Since any time there can be only one expanded item, the last expanded item is the one that takes effect ---- that's the last expanded item in the menu, not the item that was last set as expanded.
In your case, you should set an intial Expanded item (through Menu Builder, for example), set NavigateUrl and let the menu to do the rest. There is absolutely no need for you to have RaisesServerEvent set to true and then do redirect and manually expand the clicked item.
Thanks
