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

Tree View Saving

Hi team,

I am using RadTreeView in my project.the hierarchy is as below.

In Master page on Left hand side i am having the treeview.on right hand side having contentpages displaying the information related to the seleted node.
In TreeNode from context menu will go and add the records dynamically.when want to add the newnode clicks add from the context menu then the node is added and related content page is displayed on right hand side will fill the details and click on save then the node gets saved in DB.
Maintaining the state of the treeview in session by using getXml(),and setXml() of the treeview.
As of now in our treeview there is drag and drop functionality the end user will drag and drop the nodes from one parent to another parent and so on......and when clicks on save then only need to update the relations in the DB.how can i maintain the changes done by the user by drag and droping until they clicks on save.what nodes has been changed what nodes to be updated in the database.

RadSpell on separate form

Hello.

I am curious if the RadSpell will work for our scenario. I have looked at the demos, but I didn't see anything to determine if it would.

Basically we have 3 html forms: a menu form, that houses buttons such as save, exit, clear controls. This is where I would like for the RadSpell button to be located. The second form is the html content form, which has all of the user controls. The third form has a frame which holds the other two pages. I'm wondering if it would be possible to spell check items on a completely different html page than where the RadSpell control is located, and if so, how hard would it be to set this up?

Thanks

Spell
