Adding controls to the TargetControls Collection on the Client

Is it possible to add controls to a RadToolTipManager's TargetControls collection using the client-side API?

I'm populating a RadComboBox on the client and want to create tooltips for each of the items.

Scheduler - External Edit in RadDock

Hi,
I am having problems with this or I am not sure if this is a problem or if it just works like this. Here is my problem everything works fine but when I edit a recurring appointment it creates a whole new appointment with the resource changes. So it now has two appointments one that is linked to the recurring master and one that is independent. is there a way to do this where it just edits the recurring not inserting a new one. Or should I say referecnces the master in the recurrencePartentID and does not show two appointment just one. My code is the exact same as the demo I also notice that it does this on the demo also. I hope there is a way to do it the way I need it to. Thanks for any help also sorry I am very new to this so please bear with me.

Client-Side Menu Item Remove

Hi,

I'm having a problem with removing menu items from the client side. Specifically, I run into an issue when I try to remove the last root menu item.

I have noticed that you have the same issue in your demo here: http://demos.telerik.com/aspnet-ajax/menu/examples/programming/addremovedisableitemsclientside/defaultcs.aspx

To reproduce the problem, select "Books", click "Delete selected Item", then, select "Music" and click "Delete selected Item". You will find that the Music menu item still exists in the menu, and when you move the cursor over the menu, it throws a javascript exception. Is there a known work-around for this issue?

Thanks,

Brad

Display help text per item

Is there a way to display different text as a user hovers over individual items for a rad combobox? I don't care if it's a tool tip or not, it's just simple text. Basically, I have a combo box of abbreviated items, and I'd like to display the full name as you hover over them to select one.

Error in IE 10 due to telerik dlls Version=2009.2.826.35

When I tried to render Telerik reports(based on Telerik:RadControls) on IE 10 (Windows 8), then I was facing following error:
" SCRIPT5022: NoModificationAllowedError"

After that I overrided function "Telerik.Web.UI.Overlay.prototype" by the following code::

     Telerik.Web.UI.Overlay.prototype = { initialize: function () {
            var _13f = document.createElement("div");
            _13f.innerHTML = "<iframe>Your browser does not support inline frames or is currently configured not to display inline frames.</iframe>";
            this._element = _13f.firstChild;
            this._element.src = "javascript:'';";
            this._targetElement.parentNode.insertBefore(this._element, this._targetElement);
            if (this._targetElement.style.zIndex > 0) {
                this._element.style.zIndex = this._targetElement.style.zIndex - 1;
            }
            this._element.style.position = "absolute";
            this._element.style.border = "0px";
            this._element.frameBorder = 0;
            this._element.style.filter = "progid:DXImageTransform.Microsoft.Alpha(style=0,opacity=0)";
            this._element.tabIndex = -1;
            this.updatePosition();
        }, dispose: function () {
            if (this._element.parentNode) {
                this._element.parentNode.removeChild(this._element);
            }
            this._targetElement = null;
            this._element = null;
        }, get_targetElement: function () {
            return this._targetElement;
        }, set_targetElement: function (_140) {
            this._targetElement = _140;
        }, updatePosition: function () {
            this._element.style.top = this._toUnit(this._targetElement.style.top);
            this._element.style.left = this._toUnit(this._targetElement.style.left);
            this._element.style.width = this._targetElement.offsetWidth + "px";
            this._element.style.height = this._targetElement.offsetHeight + "px";
        }, _toUnit: function (_141) {
            if (!_141) {
                return "0px";
            }
            return parseInt(_141) + "px";
        }
    };

Now, I am facing another error:
"SCRIPT5007: Unable to get property 'documentElement' of undefined or null reference"

I think all these errors are coming due to IE document Mode: standard is not handling these telerik dlls of above mentioned version
So, any suggestion or solution is welcomed

"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
