Editor bug in IE when enable

I have a problem with Editor in IE.

The editor propery enable is set to "False". When I set it to "True" in codebehind, the first render of the Editor far exceeds the size set for this control (445 pixels). If I disable and enable again, the look is fine.

Here is the screenshot for the first loading and subsequent loading.

I'm using RadControls for ASP.NET AJAX Q2 2009 SP1

Have you any idea what can cause this bug?
Thank you in advance

LoadingPanel on TabStrip

Hi,

I have 3 tabs. The first 2 tabs take user input, and the final third tab displays a calcution according to the previous 2 tabs' data. I am using the OnTabClick event to check which tab the user has clicked, and if it happens to be the third then we process the users input and display the final calculation (this takes a bit of time since we are hitting the database). The tab strip is ajaxified and displays my LoadingPanel when the OnTabClick event is fired. It works great but the only issue is that the LoadingPanel also displays for the other tab clicks, where no data is needed to be calculated. Is there a way to only display the LoadingPanel for a specific TabClick instead of all tabs where some are not needed to perform calculations but others are?

My ajax manager proxy is setup as such (which causes all tabs to display the LoadingPanel):

<rad:RadAjaxManagerProxy runat="server">

<AjaxSettings>

<rad:AjaxSetting AjaxControlID="UniverseTab">

<UpdatedControls >

<rad:AjaxUpdatedControl ControlID="UniverseTab" />

<rad:AjaxUpdatedControl ControlID="RadMultiPage1" LoadingPanelID="LoadingPanel" />

</UpdatedControls>

</rad:AjaxSetting>

</AjaxSettings>

<AjaxSettings>

<rad:AjaxSetting AjaxControlID="RadMultiPage1">

<UpdatedControls>

<rad:AjaxUpdatedControl ControlID="RadMultiPage1" />

</UpdatedControls>

</rad:AjaxSetting>

</AjaxSettings>

</rad:RadAjaxManagerProxy>

Thanks,
Patrick

Image manager laod issue in IE

When I go to use the image tool for the first time, it takes quite some time to eventually load. Once it’s loaded, it seems to come back rather quickly the second time….but the initial delay is about 30 seconds….any idea what the problem might be? I found these two errors in my junk folder earlier, but I didn’t know if it was related to the delay I was experiencing.

My folder contains around 30 images.

Thanks in Advance

Site don't work after update telerik libraries 2010.2.929.35 -> 2010.3.1317.35

Hi!
I was working on asp.net application in VS2008 and asp.net ajax controls version 2010.2.929.35 and it was working fine.
A cuple of days ago I installed the lastest version of asp.net ajax controls (ver 2010.3.1317.35) and I upgrade my solution with this version, and after that the site begun to throw javascript exceptions: sys is undefined

The first exception is:
IExplorer error:

Línea: 67
Error: Error al cargar el marco de trabajo de cliente ASP.NET Ajax.

In Debug mode this is the exception:
<script type="text/javascript">
//<![CDATA[
if (typeof(Sys) === 'undefined') throw new Error('Error al cargar el marco de trabajo de cliente ASP.NET Ajax.');
//]]>

After that, all exception are: 'Sys' no está definido (sys is undefined).

If I go back to the previous version, It starts to work again.

Thanks in adavnce,
Alejandro

ScriptManager Problem

Hi,

I am using RadControls for ASP.NET AJAX Q3 2010.
I my application scenario i want to create Sliding Panel Bar & and inside Sliding Panel Bar there is drag drop control.

Drag drop control using <ajaxToolkit:ToolkitScriptManager></ajaxToolkit:ToolkitScriptManager>

but Sliding Panel required <telerik:RadScriptManager></telerik:RadScriptManager>

I am using it like this

<telerik:RadScriptManager ID="ScriptManager" runat="server">
        <Scripts>
            <asp:ScriptReference Name="PreviewScript.debug.js" Assembly="Microsoft.Web.Preview" />
            <asp:ScriptReference Name="PreviewDragDrop.debug.js" Assembly="Microsoft.Web.Preview" />
            <asp:ScriptReference Path="~/Scripts/ItemDragDrop.js" />
        </Scripts>
</telerik:RadScriptManager>

but my application given an error:
Microsoft JScript runtime error: AjaxControlToolkit requires ASP.NET Ajax 4.0 scripts. Ensure the correct version of the scripts are referenced. If you are using an ASP.NET ScriptManager, switch to the ToolkitScriptManager in AjaxControlToolkit.dll.

If I use <ajaxToolkit:ToolkitScriptManager></ajaxToolkit:ToolkitScriptManager> there is no error with drag drop. But Slider Panel required <telerik:RadScriptManager></telerik:RadScriptManager>.

How to overcome this issue.
Please help me asap.
Regds.

JavaScript Correction for GridAttachmentColumn Online Example

Hi,

I'm not sure where else to submit this so I figure I'd place it here.

There appears to be a minor omission in the JavaScript for the GridAttachmentColumn online example. Visit the example here.

Examine the conditionalPostback function:

function conditionalPostback(sender, eventArgs)

{

//The variable 'theRegexp' is never used

var theRegexp = new RegExp("\.UpdateButton$|\.PerformInsertButton$", "ig");

var eventArgument = eventArgs.get_eventArgument();

if (eventArgument.indexOf("Update") > -1 || eventArgument.indexOf("PerformInsert") > -1)

{

if (upload && upload.getFileInputs()[0].value != "")

{

eventArgs.set_enableAjax(false);

}

Draw your attention to the variable named theRegexp which appears to be a Regular Expression container. The variable is defined, but it is never used. I suspect that it was supposed to have been used in the If block that follows, like this:

if (eventArgs.get_eventTarget().match(theRegexp)){

//Disable AJAX functionality

}

...such that the final block actually reads like this:

function conditionalPostback(sender, eventArgs)

{

//This is the corrected version

var theRegexp = new RegExp("\.UpdateButton$|\.PerformInsertButton$", "ig");

var eventArgument = eventArgs.get_eventArgument(); //this variable may not be needed either

if (eventArgument.match(theRegexp)) //or eventArgs.get_eventTarget().match(theRegexp)

{

if (upload && upload.getFileInputs()[0].value != "")

{

eventArgs.set_enableAjax(false);

}

While the code that was there before would work too, it can prove to be a little confusing for people who aren't terribly familiar with JavaScript who would include that variable definition for no good reason.

Cheers,
John
