ajax update of RadMultiPage from RadWindow

Hi,

I have a RadMultiPage which is controlled by a RadTabStrip. I also have a RadWindow, which sits outside of the RadMultiPage. I need updates within the RadWindow to be reflected in the contents of the RadMultiPage. How can I acheive this? Ideally the update would be to only a single PageView.

Thanks.

On demand load noding animation icon stays visible

I have on demand loading of nodes working. My app is using ASP.NET forms-based authentication. When the user's ASP.NET session times out (default is 20 minutes) and the user attempts to expand a node then the "loading" animated icon appears and nothing happens. If the user clicks on something else that actually posts back to the server then ASP.NET displays the login form and the user can resume using the app but the animation icon never disappears.

What can be done about this?

[Solved] EnableAutomaticLoadOnDemand but with initial value

I am using the EnableAutomaticLoadOnDemand with the combo box and it's great but I have 1 problem. I need to have a row already in the combo and still be able to trigger the loading of the combo.

Here is the scenario. I have a form that display a bunch of information for a given database record. I need to show the user the associated item in the combobox but I do not want to load all of the rows of that combo until they choose to see them. I am fine with just inserting 1 row into the combo and then triggering the loading of all the combo rows when the combo is clicked.

So basically how can I achieve this scenario of inserting 1 row into the combo so the user can see the data for that item and still trigger the loading of all rows when the combo is clicked.

In my tests I have inserted a row both on the server and on the client but in doing so prevents the triggering of the LoadOnDemand.

Issue While Loading RadChart Image

Hi,

I am using Rad Controls of version 2009.2.701.35. I need to load a series of Rad Charts dynamically. The no.of charts are also dynamic. While loading the charts am getting the following error, for few charts:

Error loading RadChart image.
You may also wish to check the ASP.NET Trace for further details.
Display stack trace?

A red X mark is displayed in place of those charts.
Am able to see other charts(Like, out of 10 charts am able to see 8 or 7 charts). This error message is not consistent for a particular chart always. For a same set of records one time am getting error on 5th and 9th charts, and if I load the same page again, am getting error in different chars,(like 2nd and 4th).

I read through many forums related to this issue. I tried various options but they are not working out for me.

I tried adding,
<add name="ChartHandler" path="ChartImage.axd" verb="*"
type="Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI" />
in my system.webServer section in web.config.

As per forum I also tried adding,
<add name="ChartImage_axd" path="ChartImage.axd" verb="*" type="Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI, Version=2009.2.701.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" preCondition="integratedMode" />

I tried setting the,
RadChart rChart = new RadChart();
rChart.HttpHandlerUrl = ResolveUrl("ChartImage.axd"); from my code behind.

Am testing this in my local development environment (Visual Studio 2008). Am getting the same error in development as well as deployed location.

If anyone have solution for this, Please help me out!!!
Thanks.

string OrdID = (string)Session["orderId"];

string NoteDesc = (WinEditForm.ContentContainer.FindControl("RadPageView2").FindControl("txtNoteDesc") as TextBox).Text;

[Solved] Colourizing certain skins

Why is it that colourizing some skins appears to have no effect?

If I go in to VSB and create a skin based on, say, Office2007, pick Grid and colourize (and save) using, as an example, #00ff33 as the base colour, the "Colourization Done" window pops up and going to fine tune shows my Green coloured skin.

If I do the same thing but base my new skin on the "Default" skin then fine tuning the Grid skin after colourizing it shows a skin that looks identical to the original. I've not been through all the controls but Grid, Menu, ToolBar and PanelBar all seem unchanged. Editor shows changes in the tool icons but not the skin itself.

[Solved] OnMouseOver ComboBox

How to make radcomboBox open dropdownlist on mouseover and close the list when mouse is out the combobox dropdownlist?
I did the following :

<script type="text/javascript">

function ToggleDropDown() {

var combo = $find("<%= RadComboBoxSearch.ClientID %>");

combo.showDropDown();

}

function closeDropDown() {

var combo = $find("<%= RadComboBoxSearch.ClientID %>");

combo.hideDropDown();

}

</script>

and in code behind

RadComboBoxSearch.Attributes.Add(

"onmouseover", "ToggleDropDown();")

RadComboBoxSearch.Attributes.Add(

"onmouseut", "CloseDropDown();")

but by doing that when mouse is over the combo the list opens but when i go with mouse over the list it closes without being able to select anything.I need to close the combolist when mouse is out the combolist and not out the combo itself

selectedvalue sometimes empty with automaticloadondemand

i have a combobox that is using automaticalloadondemand. sometimes the value of selectedvalue is present and sometimes it is absent - there does not seem to be a rhyme or reason to it - but when it is absent the text value has what is in the combobox but any of the "Selected" values such as selectedindex and selectedvalue act like nothing is selected. is this a bug? if or if it is not a bug how do I work around this? I have many comboboxes with this on a page and need to only load them if the user clicks in them but I want to reliably get the value.

I am using the latest 2010 version of telerik with the combobox within an updatepanel inside a user control which is loaded on a page that has a masterpage

<telerik:RadComboBox ID="MyRadComboBox" runat="server" Width="200px" Height="100px"

MarkFirstMatch="True" DataSourceID="MyObjectDataSource" EnableAutomaticLoadOnDemand="true"

EmptyMessage="Select Something If You Want To" DataTextField="name" DataValueField="id">

</telerik:RadComboBox>
