Loadondemand and problem in obtaining selected value

Hello,

I am using loadondemand for a radcombobox control as follow:

<telerik:RadComboBox ID="DDL_district" Runat="server"

DataSourceID="DS_district" DataTextField="fullAddress



DataValueField

="recID" Width="100%" AppendDataBoundItems="True"

EnableAutomaticLoadOnDemand="True" Filter="Contains"

MinFilterLength="3" ShowMoreResultsBox="True"

EnableVirtualScrolling="True" ItemsPerRequest="10"

LoadingMessage="Loading...."

EmptyMessage="No such district in the database."

MaxHeight="250px">

<Items>

<telerik:RadComboBoxItem runat="server" Selected="True"

Text="some text"

Value="0" />

</Items>

</telerik:RadComboBox>

when I try to obtain the selected value in run-time I always get "0" value even if I select an item from database.
I use following code to get districtID value

Dim districtID As String = DDL_district.SelectedValue

Am I missing something?

Easy way to open and close radWindow

I did some search and looks like opening the radWindow is eash, just use "RadWindow1.VisibleOnPageLoad = True" on a button click will do the trick.

But closing the window is complicate. Why do I have to use javascript to close it? Is there an easier way to close it after postback?

Closing Menu in OnClientItemClicked, re-opens

Hello,

I'm currently prototyping a menu where I want a child menu item to make an Ajax call, alter the Image on the parent menu, and then close the parent menu. Here is my menu:

    
            <Telerik:RadMenu ID="Menu_gob" runat="server" Skin="Default" OnClientItemClicked="MenuItemClicked"> 
        
                <Items> 
        
                    <Telerik:RadMenuItem Value="AllTopics" Text="Top/All Topics" /> 
        
                    <Telerik:RadMenuItem Value="CurrentTopic" Text="Page Lifecycle" ImageUrl="~/CABS_Images/Icon_NotSubscribed.png"> 
        
                        <Items> 
        
                            <Telerik:RadMenuItem Value="CurrentTopicNewThread" Text="Start a New Thread" ImageUrl="~/CABS_Images/Icon_NewDocument.png" /> 
        
                            <Telerik:RadMenuItem Value="CurrentTopicSubscription" Text="Turn ON Notifications" ImageUrl="~/CABS_Images/Icon_Subscribed.png" /> 
        
                        </Items> 
        
                    </Telerik:RadMenuItem> 
        
                    <Telerik:RadMenuItem Value="CurrentThread" Text="NEW THREAD, 2, 3, 4..."  ImageUrl="~/CABS_Images/Icon_Subscribed.png"> 
        
                        <Items> 
        
                            <Telerik:RadMenuItem Value="CurrentThreadNewPost" Text="Post a Reply" ImageUrl="~/CABS_Images/Icon_NewDocument.png" /> 
        
                            <Telerik:RadMenuItem Value="CurrentThreadSubscription" Text="Turn OFF Notifications" ImageUrl="~/CABS_Images/Icon_NotSubscribed.png" /> 
        
                        </Items> 
        
                    </Telerik:RadMenuItem> 
        
                    <Telerik:RadMenuItem Value="NewPost" Text="Post a Reply" ImageUrl="~/CABS_Images/Icon_NewDocument.png" /> 
        
                    <Telerik:RadMenuItem Value="CannotPost" Text="This Thread is Read-Only" ImageUrl="~/CABS_Images/Icon_CannotPost.png" /> 
        
                </Items> 
        
            </Telerik:RadMenu>

I use the OnClientItemClicked event currently just to check the item being clicked, toggle the images, and close the menu. There's no Ajax involvement yet.

    
            <script language="javascript" type="text/javascript"> 
        
                var subbed_gbl = false; 
        
                function MenuItemClicked(sender, args) { 
        
                    var clickedMenuItem = args.get_item(); 
        
                    if (clickedMenuItem.get_value() == 'CurrentTopicSubscription') { 
        
                        var CurrentTopicMenuItem = $find("<%= Menu_gob.ClientID %>").findItemByValue('CurrentTopic'); 
        
                        subbed_gbl = !subbed_gbl; 
        
                        if (subbed_gbl) { 
        
                            clickedMenuItem.set_imageUrl('<%= Application("ApplicationPath") %>/CABS_Images/Icon_NotSubscribed.png'); 
        
                            clickedMenuItem.set_text('Turn Off Notifications'); 
        
                            CurrentTopicMenuItem.set_imageUrl('<%= Application("ApplicationPath") %>/CABS_Images/Icon_Subscribed.png'); 
        
                        } else { 
        
                            clickedMenuItem.set_imageUrl('<%= Application("ApplicationPath") %>/CABS_Images/Icon_Subscribed.png'); 
        
                            clickedMenuItem.set_text('Turn On Notifications'); 
        
                            CurrentTopicMenuItem.set_imageUrl('<%= Application("ApplicationPath") %>/CABS_Images/Icon_NotSubscribed.png'); 
        
                        } 
        
                        //  CurrentTopicMenuItem.blur(); 
        
                        //  CurrentTopicMenuItem.set_selected(false); 
        
                        //  CurrentTopicMenuItem.close(); 
        
                        sender.close(); 
        
                    } 
        
                } 
        
            </script>

This works, except that immediately after the menu closes, it opens again. As you can see, I've tried a few different things. I've closed it, blurred it, un-selected it, and in various different orders. I've done this by referencing both "sender" and "CurrentTopicMenuItem", which I programmatically set to the parent menu item. None of them do the trick. The menu always closes and then immediately opens again.

(Note that <%= Application("ApplicationPath") %> is just a way to reference the root of the web since it can vary from development to production.)

Can you help?

Progress Area resets when complete Issue

I'm using a Progress Area Control to monitor the progess of some code (actually just calling System.Threading.Thread.Sleep(4000)) for right now to simulate code doing stuff. Anyway, it runs fine until it finishes, at which point both the progress bar and the OperationText seem to "reset" back to the first thing I set it to.

For example.

I initially set the PrimaryPercent to 0 and the CurrentOperationText to: "Initialization started...". the last thing I do is set the PrimaryPercent to 100 and the CurrentOperationText to: "Initialization Complete...". It shows this on screen but then seems to reset the PrimaryPercent to 0 and the CurrentOperationText back to: "Initialization started..." before the page response is finished.

Any idea why? I'm setting the progressContext.OperationComplete = True before the final update. Here's my full code:

<asp:button runat="server" ID="btnInitialize" Text="Initialize" CssClass="button" />

<telerik:RadProgressManager ID="RadProgressManager1" runat="server" />

<telerik:RadProgressArea ID="rpaInit" Width="100%" ProgressIndicators="TotalProgressBar, CurrentFileName" runat="server" Skin="GCSD" EnableEmbeddedSkins="false">

<ProgressTemplate>

<ul class="ruProgress" runat="server">

<li class="ruProgressHeader" runat="server"><span id="ProgressAreaHeader" runat="server"></span></li>

<li class="ruFilePortion" runat="server"><div id="PrimaryProgressBarOuterDiv" class="ruBar" runat="server"><div id="PrimaryProgressBarInnerDiv" runat="server"></div></div></li>

<li class="ruCurrentFile width100Percent" runat="server"><span class="lblCurrentOperationTitle">Status:</span><asp:label runat="server" id="CurrentOperation" class="lblCurrentOperation" /></li>

</ul>

</ProgressTemplate>

<Localization Uploaded="Uploaded"></Localization>

</telerik:RadProgressArea>

Private Sub UpdateProgressMessage(ByVal progressContext As Telerik.Web.UI.RadProgressContext, ByVal strMessage As String, ByVal intPercentComplete As Integer)

Dim strScript As String

Dim writer As New StringWriter

progressContext.PrimaryPercent = intPercentComplete

progressContext.CurrentOperationText = String.Format("{0}", strMessage)

progressContext.Serialize(writer)

strScript = String.Format("{1};Sys.Application.add_load(function(){{$find(""{0}"").update(rawProgressData);}});", rpaInit.ClientID, writer.GetStringBuilder().ToString())

ClientScript.RegisterStartupScript(Me.[GetType](), "", strScript, True)

End Sub

Private Sub btnInitialize_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnInitialize.Click

Dim progressContext As RadProgressContext = RadProgressContext.Current

rpaInit.DisplayCancelButton = False

UpdateProgressMessage(progressContext, "Initialization started...", 0)

System.Threading.Thread.Sleep(2000) 'delay it a couple seconds

UpdateProgressMessage(progressContext, "Loading Stuff...", 25)

System.Threading.Thread.Sleep(4000)

UpdateProgressMessage(progressContext, "Loading More Stuff...", 50)

System.Threading.Thread.Sleep(5000)

UpdateProgressMessage(progressContext, "Loading Even More Stuff...", 75)

System.Threading.Thread.Sleep(5000)

progressContext.OperationComplete = True

UpdateProgressMessage(progressContext, "Initialization Complete", 100)

End Sub

Bind AsyncUpload on Load

Hello everybody,

First, I want to apologize for my poor english.
I'm trying to fill a asyncupload when the page loads.
The page in question is made to modify a Business Object and I want when the page load that the asyncupload is filled if a file has already been uploaded for this BO.
If it's not clear tell me in order to explain this better.

Over discussed problem: RadWindow page loads twice

Hello, yes, I know the problem is overdiscussed, but I tried all the workarounds proposed by you, still doesn't work for me..

I set ReloadOnShow = false, put the code do disable cash in PreRender handler :

Response.Cache.SetCacheability(

HttpCacheability.NoCache);
Response.Cache.SetNoServerCaching();
Response.Cache.SetNoStore();
Response.AppendHeader("Pragma", "no-cache");
Response.Expires = -1;
Response.CacheControl = "no-cache";

But the page still loads twice.

Retain selected items on sorting

I have a grid that I would like to "remember" selected items (checkbox) when the user sorts the grid. I found an article that shows how to do it client side (http://www.telerik.com/help/aspnet-ajax/grid-persist-selected-rows-client-sorting-paging-grouping-filtering.html) - as I want to avoid a postback every time they select an item. It works very nicely - as long as the selected item in on the current page they are viewing. If there are more than one page of records (ie showing 10 out of 200) - and the selected record is sorted to the end of the list and doesn't show, it forgets that it was checked. The on row created doesn't seem to fire as the row really isn't created. Is there a way around this?

Thank you in advance,
John
