[Solved] Multiple selection...

I have 'program' radlistbox that I am populating dynamically. I also add a RadListBoxItem '[ ALL ]' to this listbox which is used to select all the items.

I populate the other radlistbox depending on the selection in the 'program' radlistbox.

The issue is: I selected '[ ALL ]' from 'program' listbox. This selected all the items in the listbox and populated the other listbox accordingly. But now when i select just one item from the 'program' listbox nothing happens, the 'SelectedIndexChanged' does not fire.
Please help???

-- Code to insert the RadListBoxItem

Me

.rlbProgram.Items.Insert(0, New RadListBoxItem("[ ALL ]", 0))

-- Code that I use to loop through the listbox to select them all when '[ ALL ]' is clicked.

Select

Case Me.rlbProgram.SelectedIndex

Case 0

For i As Integer = 1 To Me.rlbProgram.Items.Count - 1

Me.rlbProgram.Items(i).Selected = True

sPrograms.AppendFormat(

"<Program id='{0}'/>{1}", Me.rlbProgram.Items(i).Value, vbCrLf)

AutoGenerateHierarchy is gone!

I just upgraded to the new Q2 2010 tools and the RadGrid's AutoGenerateHierarchy is gone! Now all of my DataRelations that I set up in the datasets do not have any impact on the RadGrid and I only see the top level. Has the functionality been removed or just moved to a different method? How can I get this to work in the Q2 tools?

AutomaticLoadOnDemand Issue

I've noticed that with you set EnableAutomaticLoadOnDemand="true" and Filter="StartsWith", when you select one of the items and then start scrolling it starts filtering out all the other items and the message box shows incorrect counts and allows you to continue scrolling until you reach the count it mentions.

It's kind of hard to explain, but you can see it being done on your demo page:

http://demos.telerik.com/aspnet-ajax/combobox/examples/loadondemand/automaticloadondemand/defaultcs.aspx

If you open the drop-down, select one of the options and then open up the drop-down you'll see the issue I'm referring to. It starts clearing out the other items, but still allows you to scroll.

I have to assume this is a bug with the AutomaticLoadOnDemand feature.

MarkFirst bug on Chrome 5?

Hi, I have the following code:

<%

rcb.DataSource = new[]

{

new { ID = 1, Value = "Sony" },

new { ID = 2, Value = "Samsung" },

};

this.Page.DataBind();

%>

<telerik:RadComboBox ID="rcb" runat="server" MarkFirstMatch="true" AllowCustomText="true" DataTextField="Value" DataValueField="ID" />

When I input character "S" to the RadComboBox, it select "Sony" and append "ony" to textbox. After that, if I input "a" he should select "Samsung". It works on IE or FF, but not on Chrome 5. On Chrome after I input "a" he insert it between "S" and "ony", so I have "Saony".

Dropdown Auto Scroll Issue

I've run into an issue where if a combobox contains enough info to generate a scrollbar, when list is dropped down if the user quickly moves their cursor over the dropdown, the list is somehow auto-scrolled instead of being left at the top of the list. Any ideas on why this may occur and how I might go about fixing it?

[Solved] XML

Hi there

I have recently started developing with the Rad Controls and have a question.....

We are experimenting with the RadMenu and have set it up to load the menu structure using the LoadContentFile method.

This is working very well and we are able to generate menus based on the current users profile/membership.

The issue is we can see no way to set the navigateURL property in the XML - How do we achieve this?

I am aware that it can be done in code but is there anyway this property can be set in the XML?

Ideally we want to manage the menu structure using numerous XML definitions as we need to customise the menu for each seperate client and would rather do this with simple updates to XML rather than editing code each time.

Any help greatly appreciated

LoadingPanel is only displayed the first time

All of my RadAjaxLoadingPanels are having the problem that they only are displayed the first time an event is fired. The second time I do a partial update on my page, they aren't visible, but the update itself works fine. Added my code below.

<telerik:RadScriptManager ID="sm" runat="server">
    </telerik:RadScriptManager>

    <telerik:RadAjaxManager ID="ram" runat="server">
    <AjaxSettings>
    <telerik:AjaxSetting AjaxControlID="ecoWrapper">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="ecoWrapper" LoadingPanelID="RadAjaxLoadingPanel1" />
                </UpdatedControls>
            </telerik:AjaxSetting>
    </AjaxSettings>
    </telerik:RadAjaxManager>

    <telerik:RadAjaxLoadingPanel runat="server" Skin="Simple" ID="RadAjaxLoadingPanel1" BackgroundPosition="Top" >
    </telerik:RadAjaxLoadingPanel>

<asp:Panel runat="server" ID="ecoWrapper">
...
</asp:Panel>

What could be the issue here? My page is within a masterpage if that matters.

Find Child Nodes by Text

I have been using your example to retain open TreeNodes after URL navigation (http://www.telerik.com/help/aspnet/treeview/tree_retain_nodes_after_urlnavigation.html).

This works fine, but just for nodes on the first level, not child nodes.
What do I have to do to search through ALL nodes and their children?

Thanks in advance for your help

Best regards

Thomas
