Request is not available in this context

Hello Telerik Team,

I m getting the HTTP Exception: Request is not available in this context.

at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData)

at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean

includeStagesAfterAsyncPoint)

Since, I can't send the whole code, I can explain on a high level where I am getting this issue:

I m trying to interact between two userControls inside a Radpageview. When sending the request from one control(RadtreeView) to Grid and rebinding it..I m getting this at the point where I bind this grid to a placeholder.
I see that the data is getting binded to the control properly but before rendering on to the page, I m coming across this error.
I m not using HttpContext.Current.Request anywhere in my code. It is rendered on to my IE with IIS7.0

Any help on this will greatly be appreciated.

All content uneditable by default using contenteditable

Hi,

Is it possible to make all content uneditable by default by, for example, specifying a div tag after the body tag, and then selectively enable editing of just the odd part of the HTML document? It would seem to make the most sense because most of the time you would want the user to edit just a small part of the web page and to have to specifiy what can and cannot be edited would be extremely tedious. I have experimented with numerous options at the beginning of the document but none seem to achieve the above.

I am wanting to give a client a basic CMS facility within the editor but to keep it relatively simple to implement.

Many thanks for any help you can offer.

Regards

Tim

XmlHttpPanel with RadAjaxPanel and Grid Demo Works Until Command Buttons are Added to the Grid

We are implementing a scenario very similar to the Telerik demo here:
http://demos.telerik.com/aspnet-ajax/xmlhttppanel/examples/gridinxmlhttppanel/defaultcs.aspx

It works fine until we add command buttons such as Edit and Delete to the grid. When paging or performing any action that needs to reload the grid, the Edit will not be inline, but rather show a form below the grid for editing.

The problem we are encountering is that the Edit and Delete buttons in the grid won't do anything. Eventhough the ItemCommand event is specified in the grid declaration.

Can anyone show an example or let us know what must be done to get this to work as expected (the Edit and Delete buttons firing the event handler, etc.)?

Thanks in advance!

[Solved] Spell Check Handler Server Error:403

Hi,
When trying to add a word to the custom dictionary, we are experiencing the following error :-

Spell Check Handler Server Error:403
403 FORBIDDEN

I've had this error before in the Lite version of the RAD editor and the simple solution was to change the permissions on the TDF folder to allow access to 'Everyone'. I've done that in this case and the error still occurs. Can you advise?

The folder path is :-

C:\Program Files\Common Files\Microsoft Shared\web server extensions\wpresources\RadEditorSharePoint\5.7.1.0__1f131a624888eeed\Resources\App_Data\RadSpell\TDF

Thanks,
Jason.

Disable node selection when using checkboxes?

Hello,
We are using checkboxes to indicate selection...

Is there a property/method to disable node selection? We'd like to disable the "selectability" of nodes.
...or is this done via CSS?

Also, is there a way to check the corresponding checkbox when the node is clicked?

Thanks,
Mark

rotator and loading part of an xml file to it

I have the following rotator that is linked to an xml file

<table><tr>

<td><img style="position:static;" id="rrButtonLeftg1" alt="" onmouseover="imgleftover('rrButtonLeftg1')" onmouseout="imgleftout('rrButtonLeftg1')" src="rotator/rotator_left_01.png" /></td>

<td>

<telerik:RadRotator ID="RadRotator1g" runat="server" Height="190px" Width="800px"

BackColor="#526b75" RotatorType="ButtonsOver" ItemHeight="100px" ItemWidth="160px"

DataSourceID="XmlDataSourceg1" Skin="" ScrollDuration="350"

FrameDuration="800">

<ItemTemplate>

<div class="itemTemplate">

<table style='margin: 1px 1px 1px 1px; background-color: transparent; padding: 0;

border: none; cursor: pointer; width: 100%; -moz-border-radius: 1px; -webkit-border-radius: 1px;'>

<tr>

<td style="width: 10%">

</td>

<td style="width: 80%">

<a href='<%# XPath("link") %>' style="width: 100%" >

<img align="center" border="0" height="130" hspace="0" src='<%# XPath("src") %>'

width="90" />

</a>

</td>

<td style="width: 10%">

</td>

</tr>

<tr>

<td style="width: 100%" colspan='3' align="center">

<a href='<%# XPath("link") %>' style='font-weight: bold; font-size: 8pt; color: #484849;'>

<%# XPath("title") %>

</a></font>

</td>

</tr>

</table>

</div>

</ItemTemplate>

<ControlButtons LeftButtonID="rrButtonLeftg1" RightButtonID="rrButtonRightg1" />

</telerik:RadRotator></td>

<td><img style="position:static;" id="rrButtonRightg1" onmouseover="imgrightover('rrButtonRightg1')" onmouseout="imgrightout('rrButtonRightg1')" alt="" src="rotator/rotator_righ_01.png" /></td>

</tr></table

The rotator shows an image and title below it
The XML file contains 12 entities. I want to do display 4 each time we click on the button next or previous.So on load i want to show only 4 images and corresponding titles without downloading all remaining others.And on next click i need to load into the rotator the next 4 entities but without doing any post back without reloading the whole page. How can i do that?

AsyncUpload and MaxFileInputsCount

Hi,

I'm using the AsyncUpload control to upload many files to the server (see the control definition at the end). The MultipleFileSelection is 'Automatic' and MaxFileInputsCount is 5. In the file selection dialog you can select as many files, but I will be limited to 5 (MaxFileInputsCount). Is there a possibillity to check this.

Detlef!

<telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server" InputSize="35"

MultipleFileSelection="Automatic"

onfileuploaded="RadAsyncUpload1_FileUploaded" OverwriteExistingFiles="True"

ReadOnlyFileInputs="True" Skin="Windows7" TargetFolder="~/Files"

AllowedFileExtensions=".csv,.zip"

AllowedMimeTypes="text/comma-separated-values,application/zip"

MaxFileInputsCount="5" MaxFileSize="1048576" Height="200px" >

</telerik:RadAsyncUpload>

hierarchial grid

I'm using the hierarchial RadGrid. I'm trying to 'tie' the nested grid to the parent grid without using a SqlDataSource as the source. (All of the demos use a SqlDataSource).
I usually do this on the 'selectedIndexChanged' event of the gridview, where i get the parent row's ID by the Selected Value. In this case, though, I don't see an event where I can retreive the DataKey value.
Is there an 'OnExpandedRow' event or 'OnNestedGridDataBound' or something similar?
