I have a listview with another 3rd party control inside of the edititem Template. This control reacts to ajax request and if certain requirements are not met with it then it in effect takes over the edit form and will not allow the page to exit edit mode. How do I cancel edit item in listview through javascript?

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.

DropDownList DDL = (DropDownList)PageView.FindControl("ddlNoteType");

I also tried another way but no luck

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

string NoteType = (WinEditForm.ContentContainer.FindControl("RadPageView2").FindControl("ddlNoteType") as DropDownList).Text;

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

Please let me know how to find the answer
