Hi, I need to perform some operations on the databound event of my RadListView however the event args do not include a data item unlike other args of the databound event, which event can I use to access the data item on databound?

I saw the Transparent skin on the RadGrid Demo page and wanted to implement it in my project but it is not an option under the Skins list.

When I look in the Telerik Project Configuration Wizard it says that the current RadControls version is v.2011.2.915.40 and it is not included until the Default Skins or in the Skin packs.

How do I get it as an option?

Hello.  I am trying to set up the RadCalendar to have custom mouseover tooltips on certain special days.  I have seen the example at http://demos.telerik.com/aspnet-ajax/tooltip/examples/tooltipcalendar/defaultcs.aspx, but I would like to set up everything on PageLoad, rather than having the tooltips on demand.  I am unclear as to how all the various elements would fit together. 

Currently I am setting the special days as follows:


Thanks in advance!

Hi,

I am new to telerik,I have implemented a calender with RadDatePicker and wanted too disable future dates.
For that in the pageload of the page I wrote this code:-

if

 

(!Page.IsPostBack)

 

{

 

this.radDatePicker1.MaxDate = DateTime.Today;

 

}

I checked it was working fine,for further testing ,I changed the system date to various dates and found that it was fine.
But after two days when I again checked,this code seemed to have no effect as all future dates are enabled.

Can anyone please let me konw how can I achieve my task?

Thanks,
Tarang

I've been asked to make a web version of an old VFP Windows application. The requirements include having a daily timeline with the times being the X axis and days being the y axis.
I'm attaching a screenshot of the windows application. Can I approximate this with Rad Scheduler? I don't necessarily need the whole answer, but if someone could point me in the right direction for setting this (or letting me know if it can't be done). Thanks!

I've been struggling with this problem for over day. While I have figured out a workaround, I wonder if anyone can explain whether there is a better way to handle it.

I have a RadGrid that is bound to a DomainDataSource. The DomainDataSource is linked to a service (LinqToEntitiesDomainService<T>) and specifically to a function in the service that returns IQueryable<Computer>, where "Computer" is an entity in our application.

In testing, I found that when the service query returned one or more "Computers", RadGrid behaves fine. However, the query function was coded (in C#) to return null when no "Computers" matched certain criteria. In this case, RadGrid did not behave as I expected. The RadGrid control would either appear as a single horizontal borderline on my page (i.e., it apparently collapses to zero height). If I set a fixed height on the control, it would then appear as an empty box.  I *thought* RadGrid was supposed to display my NoRecordsTemplate when the dataset was empty OR null. 

My workaround (discovered by accident) was to change the service function so it returns a deliberately empty query. Lo and behold, now RadGrid displays my NoRecordsTemplate exactly as intended!

What's the deal with RadGrid and a null (not empty) dataset? Is this expected behavior? If so, how did I miss that in the documentation?

I am not particularly happy about fiddling with the service function logic. I wonder if there is another workaround I can make to handle a null dataset? For instance, can I handle one of the RadGrid events and substitute an empty collection of some sort?

Thanks for any insights.

Telerik, 

I've got a regex control attached to a text box validating  a list of email addresses. When the set of email addresses is invalid a water mark appears in the textbox with a message 'Invalid email' displaying in black font.  It should be red font, but it looks like the radInput_error_default event is not being triggered and associated with the css that displays red font.  The css that is being used is the '.RadInputMgr_Default' with a color = black.  Below is the code for a sample application that does work.  Note the ajax toolkit script manager is being used.  

Can you shed any insight into this problem?

Greetings

I'm part of a project that has up until now worked with the July release of RadControls.
I've always had issues with seeing the RadDesigner components in design view but since
I've always been part of the backend I've paid it no mind.

Now however, I installed the latest version of radcontrols (Sept SP2 release I believe)
and I need to see the components in design view to do some fixes. However, I now get
a version error due to the fact (I assume) its trying to load version "2011.2.712.40"
while I just installed version "2011.2.915.40".

Since we do like to use the latest version of the third party components we use its in the
projects best interest to migrate as soon as possible to the latest version (also for me to
do my job).

The project is TFS based as usual with normal check in policies.

How do you suggest we go about solving this issue?

Thank you for your time,

Anders

I get this error message:

 There was a problem extracting DataKeyValues from the DataSource. Please ensure that DataKeyNames are specified correctly and all fields specified exist in the DataSource.

If I do:
Select sr => it works
Select sr, s.SessionNo => it does not work

If I use Anonymous types, it doesn't work at all

Link Query:
                           Dim query = From sr In db.SessionReps
                            From s In db.Sessions Where s.ID = sr.RepID And sr.RepID = repID
                            From g In db.Groups Where g.ID = s.GroupID
                            From p In db.Programs Where p.ID = g.ProgramID
                            Select New With {.ProgramName = p.Name, .GroupName = g.Name, sr.Active, sr.Attended, sr.DropOutDate, sr.ConfirmDate, sr.SessionID, s.Name, s.SessionNo, s.StartDate, s.EndDate}

How do I change the max file size allowed by the image editor that is part of the RadEditor?
I tried setting ImageManager-MaxFileUploadSize attribute of the RadEditor itself.
I tried using the ImageManager inner node of the RadEditor:

<telerik:RadEditor ID="RadEditor1" Runat="server" Width="100px" Height="100px" 
EditModes="Design" EnableResize="False" EnableViewState="False" ImageManager-MaxUploadFileSize="1024000" 
ForeColor="Black" ContentAreaCssFile="~/Styles/RadEditor.css">
    <Tools>
     	...
    </Tools>
    <Content></Content>
    <MediaManager MaxUploadFileSize="10240000" />
    <ImageManager MaxUploadFileSize="10240000" />
</telerik:RadEditor>

Nothing I do seems to be working.  It always says max size is 200K.  Any ideas?
