[Solved] Foreign chars, strange behavior

Hello
In an aspx project, I have two (very similar) pages that use a number of Telerik controls.
In both pages foreign chars like ó, é (vowels with tilde) are directy types for example in labels, and some other places
However, in one of the pages these characters display ok, in the other page they display as square boxes.

I am not using resource files, and cannot find any significant differences in the encoding, neither in aspx or aspx.vb files. Both pages use the same master page.
I attach the screenshots (screenok, screenbad) and the respective code (codeok, codebad).

Of course if I use HTML encoding (ó instead of ó) they show ok in every case, but it is a real pain...
What am I missing?

TIA

ComboBox SelectedValue Incorrect

I have used Telerik products for years, including the combobox. But I am having a problem I cannot figure out.

I have a combo box that is populated from an arraylist at page load...

===============================================================================
Page load event code to load combo box:

nopCommTopic.Items.Clear()

RCBI =

New RadComboBoxItem()

RCBI.Text =

"Select a topic..." & ",0"

RCBI.Value = 0

RCBI.Selected =

True

nopCommTopic.Items.Add(RCBI)

For Each Nop_Topic_Data In Nop_Topic_Arry

RCBI =

New RadComboBoxItem()

RCBI.Text = Nop_Topic_Data.Name &

", " & Nop_Topic_Data.TopicID.ToString

RCBI.Value = Nop_Topic_Data.TopicID

nopCommTopic.Items.Add(RCBI)

===============================================================================

The page contains a button for execution after the user selects an item from the above combo box. After the button is clicked, the code retrieves the selected value from the combo box and then continues processing. The problem is that the selected value test (see code immediately below) always gets a 0 for the selectedvalue no matter which item in the combo box is selected. It also does not matter how many different entries in the combo box that you select before pressing the processing button.

The .aspx page code for the combo is shown further below. It's pretty simple.

===============================================================================
button click event code:

' Verify that the user did select a topic to translate and save it if they did

Dim iTopic As Integer = 0

If Me.nopCommTopic.SelectedValue = 0 Then

Me.PageErrors.Text = "You must select a topic to translate from the list!"

Exit Sub

End If

iTopic = nopCommTopic.SelectedValue
===============================================================================

===============================================================================
related code from .aspx page:

<

telerik:RadComboBox ID="nopCommTopic" Skin="NeoClassic" EnableEmbeddedSkins="false" runat="server"></telerik:RadComboBox>

<br />

<asp:Button ID="TranslateTopic" runat="server" Text="Translate Selected Topic" />

===============================================================================

Can you help me figure out what is wrong?

Thanks in advance! I feel so stupid, but I cannot figure this out. I must be missing something really basic!

Trying to Collapse the Level==0 Nodes

    
            Hello, i think i've tried just about every option i can find to Collapse the ChildNodes of the Level==0 parent i suspect that 

            is has something to do with the fact that i'm not actually using the " e " in e.Nodes.... to try and do the actual process

            but i'm trying to use the actual RadTreeView ID collection itself, but the reason i'm doing that is because i want to Collapse 

            all of the Level 0 AAAA node when i then select the Level 0 BBBB node for instance, so if i tried to use the " e " value

            i would be pointing to the BBBB node which i what i want to expand, but before i expand it, i want to Collapse the AAAA node 

            just for example. thanks for any ideas or suggestins!

Getting ID of Inserted Appointment

Hi All,
I have the scheduler setup to use an

Telerik.Web.UI.XmlSchedulerProvider

to look after its bookings/appointments. This works well in that the provider handles all the inserts/updates/deletes for me.
I do, however, have a need to send a notification email to the Admin when new appointments get inserted or updated. In this email I want to provide a link to the scheduler, passing the appointment ID in the QueryString so that the appointment in question can be highlighted. This all works great for updates, as the ID is available in the

RadScheduler1_AppointmentUpdate

Method in the e.Appointment.ID property.
The same cannot be said for

RadScheduler1_AppointmentInsert

as the ID is null - I suppose the insert of the xmlProvider has not happened yet.

So my question is, at what point/event can I obtain the ID of the newly created Appointment?

Thanks for any help.
Steele.

Plot Chart Point Color

Hi, i have a very simple plot chart. The query returns a date and a int value.

When the int value exceeds a predetermined amount i want the point color red
If it's not possible to have different colors depending on a value, is it possible to have a red grid line at a given value.

Thanks

            if (!IsPostBack)  
        
            {  
        
                LadeWerte();  
        
                ZeigeTreeView();  
        
            }  
        
            .....  
        
            private void LadeWerte()  
        
            {  
        
            liste.Add(new Liste("c:\\dateien\\nord\\stad_nord"));  
        
            liste.Add(new Liste("c:\\dateien\\stad_test"));  
        
            liste.Add(new Liste("c:\\dateien\\nord\\stad_sued"));  
        
            }

From this list, I create nodes. Here is my code:

    
            private void ZeigeTreeView()  
        
                {  
        
                    RadTreeNode rtn = new RadTreeNode("Layouts", "rootfolder");  
        
                    foreach (Liste list in liste)  
        
                    {  
        
                        Rekursiv(rtn, list.pfad);              
        
                    }  
        
                    RadTreeView1.Nodes.Add(rtn);  
        
                }  
        
                private void Rekursiv(RadTreeNode node, string newnode)  
        
                {  
        
                    if (newnode != "")  
        
                    {  
        
                        RadTreeNode rtn2 = new RadTreeNode();  
        
                        string substr = "";  
        
                        if (newnode.LastIndexOf("\\") > 0)  
        
                            substr = newnode.Substring(0, newnode.IndexOf("\\"));  
        
                        else 
        
                            substr = newnode;  
        
                        rtn2.Text = substr;  
        
                        rtn2.Value = "Folder";  
        
                        string nextnode = "";  
        
                        if (newnode.IndexOf("\\") > 0)  
        
                        {  
        
                            nextnode = newnode.Substring(newnode.IndexOf("\\") + 1);  
        
                            Rekursiv(rtn2, nextnode);  
        
                        }  
        
                        node.Nodes.Add(rtn2);  
        
                    }  
        
                }

I get the following structure:

+Layouts
    +c:
        +dateien
            +nord
                -stadt_nord
    +c:
        +dateien
            -stad_test
    +c:
        +dateien
            +nord
                -stad_sued

However, I want the following structure:

+Layouts
    +c:
        +dateien
        -stad_test
        +nord
            -stad_nord
            -stad_sued

Can you help me here? Nodes that should already exist are not created again. How can I do that.

Thanks
