RadEditor adding a <br> tag automatically at the end of contents

Hello,

I am using rad editor on one of my page. I am adding RadEditor in a div which is sortable with jquery. Users can change the order of different divs on that page.

My problem is that when user moves some div up or down the editor adds a <br> in the contents. I have no idea why it is happening, can anyone help me to avoid this behavior!!

Thanks

RadToolBar combining vertical and horizontal layout

Hello,

I know that you can set the orientation of a RadToolBar to Horizantal cq Vertical.
But is it also possible to do that within one RadToolBar? I want to align a couple of RadToolBarButtons Vertical and other RadToolBarButtons to Horizontal.

So you get something like this (on 1 RadToolBar):

RadToolBarButton1 RadToolBarButton4 RadToolBarButton5
RadToolBarButton2
RadToolBarButton3

Does somebody knows a way to do this ?

Version of telerik dll that should be used in a 64 bit environment

Hi,

We have been using the telerik dll of version 2011.3.1115.35 in a 32 bit environment for developing SharePoint webparts for Sharepoint 2007 site. We are migrating from MOSS 2007 to SharePoint 2010. So would like know if the same version of telerik dll can be used in the new 64 bit environment, if not, what is the telerik version that would be compatible? We are using Visual Studio 2010 professional edition 64 bit for development.

Thanks,
Jyothi

Code for Custom validator.

protected void ServerValidate(object sender, ServerValidateEventArgs args)

{

CustomValidator custValidator = (CustomValidator)sender;

GridEditableItem eventargs = (GridEditableItem)custValidator.NamingContainer;

string Latitude = (eventargs.FindControl("txtLatitude") as TextBox).Text;

string Longitude = (eventargs.FindControl("txtLongitude") as TextBox).Text;

string UTMXCoordinate = (eventargs.FindControl("txtUTMXCoordinate") as TextBox).Text;

string UTMYCoordinate = (eventargs.FindControl("txtUTMYCoordinate") as TextBox).Text;

if ((string.IsNullOrEmpty(Latitude) || string.IsNullOrEmpty(Longitude)) && (string.IsNullOrEmpty(UTMXCoordinate) || string.IsNullOrEmpty(UTMYCoordinate)))

args.IsValid = false;

else if ((!string.IsNullOrEmpty(Latitude) && !string.IsNullOrEmpty(Longitude)) || (!string.IsNullOrEmpty(UTMXCoordinate) && !string.IsNullOrEmpty(UTMYCoordinate)))

args.IsValid = true;

else

args.IsValid = true;

Custom header and Custom item

Hi,

I am using the telerik asp.net ajax treelist to display data. For one of the column, I would like to display graphics display like rectangle, polygon or line for example showing progress of a task. For the same column, I would like to display a scale on its header column.

Is there a way to do this on client-side or server-side or both on the treelist? If yes, do you have an example for this? Thanks.

Best regards,
Melvis

Error when using TelerikRadAjax panel and TelerikRadAjaxLoadingPanel

We have an aspx page, that contains a RadGrid, TelerikRadAjax and TelerikRadAjaxLoadingPanel. We have paging for the Telerik Grid and when user clicks on paging, or does any postback on this page we show the TelerikRadAjaxLoadingPanel. This works fine in Mozilla and IE. But in Chrome, when we do a postback the TelerikRadAjaxLoadingPanel is not displayed and the page gets hanged and nothing works on this page.

Please let me know if anyone has faced such issue. I have attached the error thrown by Telerik in Chrome for reference.

Thanks in advance.

I'm using RadEditor and set the ImageManager dialog with EnableAsyncUpload = true but I can't set property TemporaryFolder of AsyncUpload like RadFileExplorer

RadEditor1.ImageManager.EnableAsyncUpload = true; // OK

RadEditor1.ImageManager.AsyncUpload.TemporaryFolder = "/Uploads"; // Does not exists

RadFileExplorer1.Configuration.EnableAsyncUpload = true; // OK

RadFileExplorer1.AsyncUpload.TemporaryFolder = "/Uploads"; // OK

Now how can I set the

RadUpload Control not working as expected

Hi,

The RadUpload is not working as expected.

I have placed the RadUpload control inside Ajax:Updatepanel in Usercontrol(.ascx), I am calling the usercontrol in my .aspx page.

Once the page get loaded, I have selected the files and tried to upload through button click event. But "radFileUpload.UploadedFiles.Count" is coming as 0. It supposed to return selected files count.

It was working fine if I placed the RadUpload control directly in to .Aspx page.(Without UpdatePanel)

So Please provide me a valuable solution.

Regards,
Saravanan M
