IIS URL Rewrite Module & Ajax not working

I recently installed the Official IIS 7 URL Rewrite module (http://www.iis.net/expand/URLRewrite) and wrote a simple rule to rewrite a website from: http://www.site.com/news.aspx?Category=Sports to http://www.site.com/Sports/ The URL Rewrite works, if you goto the later url it works, however all of the Ajax driven controls (ie the RadMenu, RadRotator, RadTabStrip etc) do not work any more.

Is there a simple fix for this?

Thank you.

Require resources, advanced date, and output errors

Hello. I need help with three things:

I need to make it required that a user selects from two resource dropdowns before attempting to submit a new appointment.
I need to make it required that the date of the appointment is after today.
I need to output error messages if either of these two do not happen.

    
                    protected void RadScheduler1_AppointmentInsert(object sender, SchedulerCancelEventArgs e)  
        
                    {  
        
                        //if the event takes place before today, cancel, preferably with an error message  
        
                        //if the resources are left empty, cancel, preferably with an error message  
        
                        if (e.Appointment.Start <= DateTime.Now)  
        
                        {  
        
                            e.Cancel = true;  
        
                        }  
        
                    }  
        
                    protected void RadScheduler1_AppointmentUpdate(object sender, AppointmentUpdateEventArgs e)  
        
                    {  
        
                        //if the event takes place before today, cancel, preferably with an error message  
        
                        //if the resources are left empty, cancel, preferably with an error message  
        
                        if (e.ModifiedAppointment.Start <= DateTime.Now)  
        
                        {  
        
                            e.Cancel = true;  
        
                        }  
        
                    }

Using the above functions, I can prevent insertion/editing-in a prior date, but how do I get the scheduler to output an error message?

And how do I require resource selection from dropdown menus AND provide errors for those as well?

Thanks in advance.

[Solved] Multiple Items in RadComboBox

I've got a problem with filling RadComboBox. Every time, the user clicks on the scrollbar all items are added again.

My RadComboBox looks like (its within a table):

    
                                                                    <telerik:RadComboBox ID="radComboBoxPLZ" Runat="server" Width="50px" DropDownWidth="260px" MaxHeight="200px" 
        
                                                                        OnItemsRequested="radComboBoxPLZ_ItemsRequested" EnableLoadOnDemand="true" MarkFirstMatch="true"   
        
                                                                        CollapseDelay="100" TabIndex="1">  
        
                                                                        <HeaderTemplate> 
        
                                                                        <table style="width: 220px" cellspacing="0" cellpadding="0">  
        
                                                                            <tr> 
        
                                                                                <td style="width: 40px;">  
        
                                                                                    PLZ</td> 
        
                                                                                <td style="width: 120px;">  
        
                                                                                    Gemeinde</td> 
        
                                                                                <td style="width: 20px;">  
        
                                                                                    Kanton</td> 
        
                                                                            </tr> 
        
                                                                        </table> 
        
                                                                        </HeaderTemplate> 
        
                                                                        <ItemTemplate> 
        
                                                                            <table style="width: 220px" cellspacing="0" cellpadding="0">  
        
                                                                                <tr> 
        
                                                                                    <td style="width: 40px;">  
        
                                                                                        <%# DataBinder.Eval(Container, "Text")%> 
        
                                                                                    </td> 
        
                                                                                    <td style="width: 120px;">  
        
                                                                                        <%# DataBinder.Eval(Container, "Attributes['Gemeinde']")%> 
        
                                                                                    </td> 
        
                                                                                    <td style="width: 20px;">  
        
                                                                                        <%# DataBinder.Eval(Container, "Attributes['Kanton']")%> 
        
                                                                                    </td> 
        
                                                                                </tr> 
        
                                                                            </table> 
        
                                                                        </ItemTemplate> 
        
                                                                    </telerik:RadComboBox>

And my CS-Code looks like:

    
                protected void radComboBoxPLZ_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e)  
        
                {  
        
                    if (e.Text.Length < 1)  
        
                        return;  
        
                    string sqlSelectCommand = string.Format("Select p.PLZ, k.Gemeinde, k.Kanton from AAV_TEST_PLZ_ORTE_GEMEINDE p, AAV_TEST_GEMEINDE_KANTON k where p.KANT_GEM_ID = k.ID and p.PLZ LIKE '{0}%' ORDER BY p.PLZ", e.Text);  
        
                    DataTable dataTable = null;  
        
                    using (OleDbDataAdapter adp = new OleDbDataAdapter(sqlSelectCommand, AdresssucheParameter.ConnectionString))  
        
                    {  
        
                        dataTable = new DataTable();  
        
                        adp.Fill(dataTable);  
        
                    }  
        
                    foreach (DataRow dataRow in dataTable.Rows)  
        
                    {  
        
                        RadComboBoxItem item = new RadComboBoxItem();  
        
                        item.Text = (string)dataRow["PLZ"];  
        
                        item.Value = dataRow["PLZ"].ToString();  
        
                        //zusätzliche Spalten  
        
                        item.Attributes.Add("Gemeinde", dataRow["Gemeinde"].ToString());  
        
                        item.Attributes.Add("Kanton", dataRow["Kanton"].ToString());  
        
                        radComboBoxPLZ.Items.Add(item);  
        
                        item.DataBind();  
        
                    }  
        
                }

In den Page_Load-Event I do nothing, beceause I don't want to load all the items beacause it takes too long. And I can't use WebService, because I need to get the value from the ComboBox in an other ComboBox with:

string

plz = e.Context["FilterStringPLZ"].ToString();

I'm looking for an solutin since 2 days and can't find an answer. It's very frustrating because I'm testing with yout Trial Version - when it looks good, we would like to pay the software.
Thanks for your anser! Bye

Possible bug (Maximized Windows)?

I'm currently experiencing the following issue in my development environment that can also be reproduced on one of the demo pages.

Steps to reproduce:

Go to: http://demos.telerik.com/aspnet-ajax/window/examples/windowmanager/defaultcs.aspx
Click on the Maximize button of the window that doesn't have the focus (the bottom most window)
Click on the Maximized Window.

Observation:

The bottom most window is maximized; however, the top most window appears on top of the maximized window. When I click on the maximized window, the minimized window still appears.

Expected result:

The z-index of the bottom most window (the one that was maximized) should be greater than the top most window and it's opacity should be 1.0. When the maximized window obtains the focus, the minimized window should no longer be visible.

Version:

2009.2.701.35

Is this a bug? Is there a work-around or solution?
