"Loading" Text

Hi,

I am populating a radcombobox using the item requested server event. The data is fetched from the database instantly and its being populated. I want to display a "Loading" text explicitly and then only it should be populated. Any possible method?

Thanks,
Shahi.

RadListBox reordering event

I am trying to use the drag-and-drop reordering capabilities of the list box control. I see that there is an Index property in the EventArgs that seems to vary depending on where I drop the dragged list items. I don't, however, understand the value of this property. If I am moving items down in the list, Index seems to be the 0-based index of the item after which the dragged items have been dropped. If I am moving items up in the list, the Index property seems to be 1 more than that. Perhaps I am thinking of this incorrectly. Could you please explain the expected behavior? Thx.

how do I show the RadAjaxLoadingPanel when I perform a javascript __postback

Problem: how to show a RadAjaxLoadingPanel from an ascx after a javascript _doPostBack

First I explain my situation…

Main page containing an ascx. In the main page I must have ajaxManager and ajaxLoadingPanel

ASPX

<telerik:RadCodeBlock ID="RadCodeBlockMain" runat="server">

<script type="text/javascript">

var currentLoadingPanel = null;

var currentUpdatedControl = null;

function RequestStart(sender, args) {

currentLoadingPanel = $find("<%= RadAjaxLoadingPanel1.ClientID %>");

currentUpdatedControl = "<%= Panel1.ClientID %>";

//show the loading panel over the updated control

currentLoadingPanel.show(currentUpdatedControl);

}

function ResponseEnd() {

//hide the loading panel and clean up the global variables

if (currentLoadingPanel != null)

currentLoadingPanel.hide(currentUpdatedControl);

currentUpdatedControl = null;

currentLoadingPanel = null;

}

</script>

</telerik:RadCodeBlock>

<telerik:RadScriptManager ID="RadScriptManager1" runat="server" />

<telerik:RadAjaxManager ID="RadAjaxManagerMain" runat="server">

<ClientEvents OnRequestStart="RequestStart" OnResponseEnd="ResponseEnd" />

</telerik:RadAjaxManager>

<asp:Panel ID="Panel1" runat="server" HorizontalAlign="Center">

<uc:polContainer runat="server" ID="polContainer1" />

</asp:Panel>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" >

<div>

<asp:Image ID="Image1" runat="server" ImageUrl="/ajax_loader.gif" />

</div>

</telerik:RadAjaxLoadingPanel>

ASCX

Based on several conditions I fill a literal with Html code loaded on code behind which represents my results which consists in a set of items each one having a clickable part (*Y). The goal is – by clicking an item – reload the result page (ascx) with other items using ajax.

I did that calling in *Y a javascript that performas a __dopostback. That works fine.

The question is how do I show the RadAjaxLoadingPanel when I perform the postback? ?

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script type="text/javascript">

function myFunct(id) {

__doPostBack ('<%=UpdatePanel1.ClientID%>', id);

}

</script>

</telerik:RadCodeBlock>

<asp:UpdatePanel ID="UpdatePanel1" runat="server">

<ContentTemplate>

<asp:Literal ID="LiteralResult" runat="server" />

</ContentTemplate>

</asp:UpdatePanel>

.vb

…

LiteralResult.text+=”<a onclick=""myFunct('" & id & "')"" >" & here_text & "</a>"

…

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Page.IsPostBack Then

Dim passedTargetId As String = = Request.Params.Get("__EVENTTARGET")

Dim passedArgument As String = Request.Params.Get("__EVENTARGUMENT")

If passedTargetId = UpdatePanel1.ClientID Then

‘do something

End If

End Sub

Thank you for your attention

Hi Telerik,

I was wondering if there is any way to position the transferring buttons below the radlistbox. The radlistboxes are one below the other, but the button are placed on right hand side of the first radlistbox. I tried with CSS but I didnt get my required style.

Thanks for replying,
Damian.

Save client-side Cloned Dock with StorageProvider

Hi,

I'm using Js code to clone a dockzone and append it to a div:

dockZone = $find("<%=RadDockZone_Empty.ClientID %>").clone();

dockZoneElement = dockZone.get_element();

$telerik.$(dockZoneElement).css("display", "block");

$telerik.$(dockZoneElement).css("width", "100%");

$telerik.$(dockZoneElement).css("min-height", "155px");

document.getElementById("test").appendChild(dockZoneElement);

Then I want to save the layout using StorageProvider.

' save the raddocklayout

RadDockLayout1.StorageProvider.SaveStateToStorage(

"123456"

, SaveState)

Private Function SaveState() As String

Dim dockStates As List(Of DockState) = RadDockLayout1.GetRegisteredDocksState()

Dim serializer As New JavaScriptSerializer()

Dim converters As New List(Of JavaScriptConverter)()

converters.Add(New UnitConverter())

serializer.RegisterConverters(converters)

Dim stateString As String = [String].Empty

For Each state As DockState In dockStates

Dim ser As String = serializer.Serialize(state)

stateString = stateString + "|" + ser

Next

Return stateString

End Function

However the client-side created dockzones and the docks inside the dockzones are not saved.

I assume the client-side created dockzone cannot be handled by the code-behind's GetRegisteredDocksState ?

What is the correct method to save the client-side cloned dockzone to the database or to get the serializedState ?

Thanks.

RadTextBox MaxLength Miss counted

I am currently using Telerik RadControls for ASP.net Ajax Version 2012.3.1308.45,
When I set a MaxLength for RadTextBox to 255, everything works correctly except when Copy and Paste text or using mouse right click to paste text into the RadTextBox, it allow the line break '\n\r' to bypass the MaxLength count.
Somehow from runtime value, I check and compare the length is more than the MaxLength.
This senarios happens in all sorts of browser (FF, IE, Chrome) and even in the Demo site,
I don't understand if this is the correct behaviour or bugs based on the calculation logic.

I would need to include the count for line break '\n\r' as well else it will hit SQL length limit to cause insert or edit error.
What else can I do to cater this?

RadListBoxItemCollection error

I just uninstalled all my old telerik controls and installed the latest version of winforms 2013.1.321.0.

I working on a project that I haven't touched in a couple of years. When I opened out the c# project I get many errors.

RadListBoxItem was giving me an error so I changed it to RadListDataItem and the error went away. I haven't been able to view my forms because I have so many errors.

This is the error i'm stuck on now and if anyone can help it would be greatly appreciated.
This is my code previously

RadListBoxItemCollection itemsToMove = new RadListBoxItemCollection();

and I get this error:

Error 2 The type or namespace name 'RadListBoxItemCollection' could not be found (are you missing a using directive or an assembly reference?)

I changed the code to

RadListDataItemCollection itemsToMove = new RadListDataItemCollection();

and this is the error i'm getting.

Error 2 'Telerik.WinControls.UI.RadListDataItemCollection' does not contain a constructor that takes '0' arguments

Thank you
