1) The Office 2007 skin is being applied to our application via the web.config, but the MultiColumn comboBox we are creating does not seem to inherit the look and feel that the rest of the controls get (We are using an item template). How do we fix that?
2) How do you apply a Selected Value column to the MultiColumn example? We are using the item template, and have specified the DataValueField and DataTextField names in the declaration, is that all there is to it?
I am guessing that we don't use the id which we want to use for the selected value in the item template, and it will bind but be invisible to the user?

Master/Detail Navigation in Separate Pages

Folks,

Here is the Scenario.

I have a Master Page (Main.Master) and 2 Content Pages(Default & Default1.aspx). Master Page page has Company Header Logo and Other controls that are common to both .aspx Pages.. When I add both .aspx pages in the Project, I indicated Main.Master is their Master Page.

I have Link Buttons controls in Both Pages for Navigation Purposes. For Default.aspx Link1 Button On Click Event, Resonse.redirect("Default1.aspx") and Vice Versa.

My question is there any sample site or example in Radcontrols for Asp.Net Ajax to accomplish the Task? That will be appreciated.. I looked at Live Demos/Menu/Examples/Functionality/Templates/DefaultVB.aspx, tried to implement in Master Page. But the problem is that If I click the content pages Navigation Buttons, I loose my Master Page header contents (TEMPLATES logo in this example). I do not want to loose the header content of my Master Page, I want to retain them as I navigate between content pages. In the Past, I did this type of Job via SiteMapDataSource but I would like to implement from Telerik Rad Menu if possible..I am using RadControls for ASP.NET AJAX Q2 2009. Also any Telerik Tutorial will be Helpful.

Thanks

Ghulam

Radwind size issue on postback from client side

Hi,

I am using master and content page in my application.
master page controls are radscriptmanager,radajaxmanger,
content page controls are radajaxproxymanager,radwindowmanager, radtabstrip and rad multipageview.

Windowmanager settings are
<telerik:RadWindowManager ID="rWindowManager" runat="server"

ClientCallBackFunction="CallBackData"

Left="" Skin="Vista" Top="" Behavior="Reload,Close" InitialBehavior="None" >

<telerik:RadWindow ID="rWindowUsersList" runat="server" Height="270px" Left="50px"

Modal="True" NavigateUrl="" ReloadOnShow="True" Title="Users List" Top="50px"

VisibleStatusbar="False" Width="280px"

OnClientClose

="DateWindowCancelClicked"

/>

</Windows>
</telerik:RadWindowManager>

When i open the radwindow on button click first time its work fine.
when i use javascript to do postback by using following method.

var ajaxManagerMaster = $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>");

ajaxManagerMaster.ajaxRequest();

But when second time i open the window it is not opening with the proper size which are specified in radwindow.
It is also not calling the OnClientClose function specified in radwindow manager.

Selected tab to Session without autopostback

Hello

I have a tabstrip on a page. On a few applications I need to do a complete postback to upload files or reload data.

I want to remember the tab they were on and reload that page.

I have the following code working in page load

    
                    If Not Page.IsPostBack Then  
        
                        Dim TheTab As String = "" 
        
                        TheTab = Session("Tab")  
        
                        If TheTab <> "" Then  
        
                            Try  
        
                                ' Set Tabstrip  
        
                                RadTabStrip1.FindTabByText(Session("Tab")).Selected = True 
        
                                'Set MultiPagePage  
        
                                RadMultiPage1.FindPageViewByID(RadTabStrip1.SelectedTab.PageViewID).Selected = True 
        
                                Session("Tab") = ""  
        
                            Catch  
        
                                ' OK if it fails  
        
                            End Try  
        
                        End If  
        
                    End If  
        
                    'Reset Tab Session  
        
                    Utilities.SetSession("Tab", RadTabStrip1.SelectedTab.Text)

However i have to set the tabstrip to autopostback to get this. The tabs perform WAY ! better clicking between them w/o it and there is absolutely no need to do a postback on just clicking between pages.

I am bad at Javascript - probably why i write in VB Is there an easy conversion of this method on the client side ?
Or an example i am not finding ?

RadGrid ExportSettings Custom Paging, Filtering Issue

Hi,

I have a RadGrid to which I am applying custom paging and filtering. Radgrid only fetches and displays data depending on the page size. For example, If I have a display 1million records and my pagesize is 10, then my view will fetch and displays only 10 records filling virtualItemCount as 1million.

Now, I want to export this data to CSV, PDF and Excel. Export settings is exporting only data(in this case 10records) as ouput to a file but I want to export 1million records in this case.

Is there anyway to give another set to the export settings to export to a file.

Thanks,
Mahesh

Unexpected behaviour using AutoPostBack

I want to have a calendar where a date selection causes a user to be redirected to an appropriate page. So, I set AutoPostBack="true" for the RadCalendar control and handle the SelectionChanged event on the server-side. Although, if user navigates from the page back to the calendar and hover the mouse over the previously selected date it appears selected.

How to replicate...

Markup:

    
            <html xmlns="http://www.w3.org/1999/xhtml"> 
        
            <head runat="server"> 
        
                <title>Untitled Page</title> 
        
                <meta http-equiv="expires" content="-1" /> 
        
                <meta http-equiv="Pragma" content="no-cache" /> 
        
            </head> 
        
            <body> 
        
                <form runat="server"> 
        
                <asp:ScriptManager runat="server" /> 
        
                <telerik:RadCalendar ID="RadCalendar1" runat="server" AutoPostBack="true" /> 
        
                </form> 
        
            </body> 
        
            </html>

Codebehind:

    
                Private Sub RadCalendar1_SelectionChanged(ByVal sender As Object, ByVal e As Telerik.Web.UI.Calendar.SelectedDatesEventArgs) Handles RadCalendar1.SelectionChanged 
        
                    Dim d As String = e.SelectedDates(0).Date.ToShortDateString() 
        
                    RadCalendar1.SelectedDates.Clear() 
        
                    Response.Redirect("WebForm1.aspx?date=" + d) 
        
                End Sub

When the user presses the browser back button I want the calendar to be "fresh" and not have the hidden selection.

Thanks.

Editor doesn't function after partial postback on Firefox

Hello,

I am using a RadEditor control which loads for the first time as a result of a partial postback.
When I'm using Firefox (3.5.1), the button causes the Editor to render with the text area locked for editing, and sometimes the text area is also much smaller then expected.

Here is the source code of an ASPX and ASCX file which reproduces the problem:

RadEditorAjax.aspx:

<%

@ Page Language="C#" AutoEventWireup="true" %>

<%

@ Register TagPrefix="uc" TagName="radAjax" Src="radAjax.ascx" %>

<%

@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
