Does RadWindow have behaviors of ModalPopupExtender

Hi,

I have a requirement that I need to implement a modal popup if a hyperlink is clicked on a page. When the modal popup is selected, the user is given a message asking if they wish to leave the site and there are two buttons on the site (cancel and ok). If ok is clicked, a new window is opened and the user is navigated to the target url in the new window.

If the cancel button is clicked, the popup closes and the user remains on the page.

There is styling involved as well since when the window opens the page behind it appears to be disabled. With the ModalPopupExtender, this is done using the BackgroundCssClass which is something like

.modal-background

{

width:100%;

min-height:100%;

position:fixed;

top:0;

left:0;

z-index:100000;

background-color:#333333;

opacity:0.55;

-moz-opacity:0.55;

filter:alpha(opacity=55);

}

Does the RadWindow implement the same kind of functionality and if not, are there any RadControls that do?

Thanks,

Window

Recurring Appointment and GetAppointments failure

Hey Everybody,

I'm binding my RadScheduler to a custom data provider via a WCF service. When I use GetAppointments to return a non-recurring appointment, everything is fine. However, as soon as I try to return a recurring appointment, I get "The server method 'Get Appointments' failed". If I put a break-point in the WCF GetAppointments method, I notice that it is being called repeatedly without throwing any exceptions, but then fails and returns NO exception information to the client. Anybody have any idea what might be happening? Seems like there's some type of infinite loop happening, but I have no idea why. Any help would be greatly appreciated!

Thanks,
Landon

RadWindow scrolling ignoring scroll

Hi, I have a page with several controls including a RadGrid. In it, I have a LinkButton that opens a RadWindow popup using the radopen() command. It works perfectly, the only problem is that the grid is on the bottom of the page and when I press the button to inside on of the grid's rows the RadWindow opens at the top of the page and my grid looses focus since the page is automatically scrolled to the top. I included two screenshots to illustrate my problem: Screenshot 1 shows the grid at the bottom of the page; Screenshot 2 shows the page after the window is opened. Here you can clearly see the problem. I have researched your forums and codebase to no avail. Remember that it is not a RadGrid's popup I am opening... it is a completely independent one triggered by a LinkButton inside the Grid. Here is my RadWindowManager definition I have in the page:

<telerik:RadWindowManager ID="MasterWindowManager" runat="server" Modal="True" Skin="Black"

AutoSize="True" Width="450" Height="300" ShowContentDuringLoad="False"

Style="z-index:7001" Behaviors="Resize, Close, Maximize, Move, Reload"

DestroyOnClose="False" EnableShadow="True" KeepInScreenBounds="True" ReloadOnShow="true" VisibleStatusbar="False">

<Windows>

<telerik:RadWindow ID="DefaultPopup" runat="server" DestroyOnClose="false"/>

</Windows>

</telerik:RadWindowManager>

Thanks for any help,
Manuel

Hi,
I have already seen the error folowing path: http://www.telerik.com/community/forums/aspnet-ajax/menu/296630-multi-column-menu.aspx.
Now i use the Telerik with version: 2010.1.421.20. Can you send Service pack to fix this error?

Also, i want to fix other error: space of "Root RadMenuItem1" element to "|" element is small. My coding is below:

        padding: 0;
        text-align: center;
        width: 1000px;
    }




</style>
<script type="text/javascript">

    function OnClientItemOpeningHandler(sender, args) {

        var item = args.get_item();
        // runtime positining of the submenu
        setTimeout(function() {
            var offset = item.get_element().clientWidth - item.get_childListElement().clientWidth;
            $telerik.$(".rmSlide").css("left", offset/2);
        }, 0);

Calling a JS function on Ajax call

I used a Radpanel embedded with RadMultiPage. I used a javascript to perform some computation, values needs to be computed when data is retrieved from the database. This causes a postback on the "panel" and the values computed by the javascript is cleared. I need to call the javascript when the postback occur. I placed a call on the page load event. This didnt work, what can I do?

Thanks in advanced

RadBinaryImage - The provided binary data may not be valid image or may contains unknown header

Hi All:

I have loaded my db column declared as follows:
[Thumbnail] [varbinary](max) NULL

I have loaded the column as follow:

Dim _pdfStream As FileStream = Nothing

Dim _fileName As String = "C:\Src\Proj\trunk\Data\2010-05-May-Cover.pdf"

If My.Computer.FileSystem.FileExists(_fileName) Then

_pdfStream = New FileStream(_fileName, FileMode.Open, FileAccess.Read)

Dim _length As Integer = CInt(_pdfStream.Length)

Dim _contents(_length) As Byte

_pdfStream.Read(_contents, 0, _length)

_pdfStream.Close()

' ... insert _contents into db

End If

I reference as follows:

<asp:FormView

id="mImageFormView" runat="server"

DataSourceID="mImageDataSource">

<ItemTemplate>

<telerik:RadBinaryImage ID="rbiThumbnail" runat="server" Width="180px" Height="220px"

DataValue='<%# Eval("Thumbnail") %>' AlternateText='No image'

/>

</ItemTemplate>

</asp:FormView>

I am getting the following:
The provided binary data may not be valid image or may contains unknown header

Anything wrong?
How do I verify that the image data is stored correctly?

When using radUpload in this page, it doesn't matter which one is clicked; file is always uploaded.

Is there any way to select which element does the uploading?
