Questions on UI for ASP.NET AJAX Forum

Hello,

Our online version of RadEditor is 7.3.2 – RadEditor for ASP .NET

While attempting to migrate to the RadEditor for ASP .NET AJAX we’ve came across these problems:

1. We’re interested in having the editor strip HTML tags (except for BR tags) when the user pastes content into it. Since the stripping is problematic in FF, we’ve written some client code to bring the “paste plain text page” up when the user tries to paste. This is the code we have online:

function OnClientCommandExecuting(editor, commandName, oTool)

{

var browserName=navigator.appName;

if (commandName == "Paste" && browserName!="Microsoft Internet Explorer")

{

editor.Fire("PastePlainText");

return false;

}

We’ve changed it to fit the new version thus:

function OnClientCommandExecuting(editor, commandName, oTool)

{

var browserName=navigator.appName;

if (commandName._commandName == 'Paste' && browserName!="Microsoft Internet Explorer")

{

editor.fire("PastePlainText");

return false;

}

Which works, but the behavior is different! Instead of bringing up the “paste plain text page”, the editor first puts the clipboard’s content in the content-area of the editor, and only then brings the page up, thereby rendering our efforts useless.
Please advise as to what we can do to solve this problem ?

2. Another problem is, when the user clicks the “paste” button, the “Please use Ctrl+V to Paste” msgbox appears before the “paste plain text page” appears.
How do we suppress this in the new (AJAX) version ?

Problem with Version 1/2010 under Mono

Hi
I am using the Telerik controls under Mono and have a page with a grid. In the Q3/2009 version everything worked fine. With the Q1/2010 version I get a strange error.
Heres's the error message:

'GridDataTypeConverter' is unable to convert 'System.MonoType' to 'System.ComponentModel.Design.Serialization.InstanceDescriptor'.

Description: HTTP 500. Error processing request.

I use the Mono version 2.4.2.3. Are there any limitations for the new Telerikm version or do you have any suggestions what to do next?

Best regards.

ajaxRequestWithTarget within UserControl

I'm struggling to find the right way to do this.

I have a user control with a RadGrid and an Edit button in it. Clicking the Edit button retrieves the primary key for the selected row within the RadGrid and opens a RadWindow passing the primary key to the page opened in the window using a Query String.

Then I have a javascript routine that handles the Window close and does a Rebind on the RadGrid to refresh it with the latest values. I use the argument from the Window to get the primary key again and select the corresponding row in the RadGrid. This is done by calling

var

ajaxManager = $find("<%= this.Page.AjaxManager.ClientID %>");
ajaxManager.ajaxRequestWithTarget('<%= Button_EditEntry.UniqueID %>', oWnd.argument);

The trouble is, this works fine within a page, but within a UserControl I seem to be faced with a dilema:

To retrieve the argument passed in the Ajax Request, I have to implement a RaisePostBackEvent method in my code-behind. For a page, this is a simple matter of overriding the page's implementation of this. For a UserControl, I have to implement IPostBackEventHandler. According to the documentation, to ensure that my RaisePostBackEvent function gets called, I have to call ajaxRequestWithTarget using the UniqueID of the UserControl itself instead of the button, but if I do that, all the controls within the UserControl get updated during the Ajax Request instead of just those controls that Button_EditEntry should affect.

Within a UserControl, how can I initiate an Ajax call on the client side, retrieve the argument on the server side, and limit the controls that are updated to one or two instead of the entire UserControl?

RadTimePicker javascript error after postback

Hello,

I have 2 RadTimePickers on an custom AdvancedEditTemplate for the Scheduler.
If I first click on the TimeInputButton and after that I do a Postback from inside the AdvancedEditTemplate, I can't click again on the TimeInputButton.
After some debugging, we found out that the _onTimePopupImageClickHandler handler is called twice. The first call succeeds, but the second one fails in getCorrectScrollLeft() from Telerik.Web.CommonScripts because A.document.documentElement is null.

Could you please provide a workaround or some advice for this? Is this a known issue?

Best regards,
Cantemir

[Solved] ControlsToSkip="Fieldset" DecoratedControls="GridFormDetailsViews" in Q1 2010

This combo doesn't work in Q1 2010, the FormDecorator applies skin to Fieldset.

The situation I have is asp:detailsview and RadListView in the same RadWindow.
FormDecorator messes up RadListView so I had set it to skip Fieldset and that works for Q3 2009 but Q1 2010 messes up either RadComboBox that is in the asp:detailsview or the RadListView.

Any hints on overcoming this limitation would be appriciated.
Using asp:dropdownlists instead of RadComboBoxes would ruin concistent look of the application.

Yours
