Hi,

Date picker gets cut off horizontally in TimelineView when there are no appointments in the calendar.
Does anybody know a fix for this?

I have a RadToolTipManager set up with AutoTooltipify to change all of my tooltips to be RadToolTips.  These have no particular sizes because they are all the small img alts, etc.

Now I have the need to take a particular ToolTip and make the size 400x350 with scrolling but I am finding that the ToolTip is still falling under the RadToolTipManager. 

Any suggestions on a work around?

Hi Telrik Guys !

 I have deployed my application on to the SERVER.

 When I try to create an FOLDER withan application Iam getting the following exception :-

FileSystem's restriction: The directory '" + virtualTargetPath + "' cannot be created!";  

But , when I try to create a FOLDER within an application(within  LOCAL END), Iam able to CREATE a FOLDER.

Could you guys please suggest me whether there are some permissions issues for the folder or any other problem that exists on to the server.

Please help.

Hi.

The company I am working uses the RadNumericInput control with it's language set to Danish (Denmark). We need to allow the users to type in the group/thousands separator (i.e., comma - 1.750,75). However, the control only allows the input of the decimal symbol. Is there a way to let the users type in the group/thousands separator because it is part of the requirement of the application?

Thanks for your reply in advance.

Hi,

A. I bound a radGrid control to a custom collection called FactoryList(of Tkey).
B. The FactoryList control derived from BindingList (of Tkey) and implements ITypedList as follow:
    1. The GetItemProperties return a collection of ColumnPropertyDescriptor objects, each is derived from PropertyDescriptor class
    2. The ColumnPropertyDescriptor class exposes information based on DataColumn meta-data i.e. ColumnName, ColumnType, and also handle SetValue and Get Value methods.
 
C. A FactoryList instance contains objects that are derived from a base class called BaseEntity. The BaseEntity class implements

ICustomTypeDescriptor, where the GetItemProperties retruns a collection of ColumnPropertyDescriptor same as the FactoryList class does.
D. I use the NeedDataSource event to bind the FactoryList to the radGrid  

All works fine, till I sort the grid rows by clicking on one of the grid column headers. In that case I got the following error:

No property or field 'LST_NAME' exists in type 'Object'  

 -  'LST_NAME' is one the columns I was trying to sort

I have tabstrip/multipage. pageviews are filled from user controls. I need to input some data (like first/last name) on the first pageview and then show this value on other pageviews.
server-side assigning is absolutely not appropriate as I have page already rendered when I start my input with the first tab clicked.
So I decided to change variables with jQuery on client-side when the tab is clicked.
But My Jquery cannot find the classes (and variables) from the pageviews.

When I take a look at page source I see that there is only first pageview. I assume that others are rendered dynamically.

Can you please advice me the best technique how I can change the variables with the same names and same classes on all my pageviews?

I tried the option to render page "OnDemand", but it didn't help.

Hi, I am using a browser add-on called httpwatch which allows me to see network traffic while I upload a document, I notice when i am uploading I get a lot of HTTP 401 unauthorized errors which should not happen since I am an authenticated user, then imeadiately I get code 200 which indicates OK, I get this every few hundred bytes until the upload completes.  Can anyone explain what is happening here, I am executing some server side processing on the files in UploadedFiles collection so the Target property is not set.  The site does have windows authentication turned ON but again I am a authenticated user.  Is there any permissions needed to be applied because I am doing server-side processing.  I am using 2009 Q2 build 826.35.  Most of the 401 errors come from the RadUploadProgressHandler.ashx issuing GET requests.

Thanks Kerry

The parent Grid displays Committee Name for example student committee. When I click on the student committee it loads the rad grid inside the nested view template that displays me the names of the student associated to that committee.

If there aren't any students for that committee it should display the message from no records template.

My questions are:

When the I call the child rad grid from the nested view template it does not display message from the no record template.
Secondly if there is data it does not display data either on the child grid.
But when I click the add button on the child rad grid it fires the NeedDataSource Event on the Child grid and displays the no records template message or displays student data then!

Can you please tell me how do I handle this, since after I  click the committee name it should call the need data source event on child but it isn't doing that for some reason can you kindly let me know about it.

Thanks and Regards
