Any Updates ????????

[Vasil]

Hello Vignesh,

There was and bug that we found inside the styles collections for each day of the calendar, that is serialized from server to client if you set styles on OnDayRender server side event.
You can update tomorrow to the Service Pack of Q2 2012 when it become available and see if the problem will be resolved.

Just so you know, this problem is still there.

Hi Osama,

Could you tell us your version of the controls and describe the exact problem. The bug mentioned earlier in this discussion is already fixed so if you have similar problem it is caused by something else.

I have upgraded to the latest version (2012 Q3), but the problem is still there.

When doing:

Private Sub RadCalendar1_DayRender(sender As Object, e As Telerik.Web.UI.Calendar.DayRenderEventArgs) Handles RadCalendar1.DayRender
      If e.Day.Date = Now.Date Then
          e.Cell.CssClass = "MyTestClass"
      End If
  End Sub

The css of the cell becomes 'MyTestClass' but, when the day is selected, the css class is 'rcSelected' when it should be 'rcSelected MyTestClass'. Also, when the mouse is over the day, the css is 'rcHover' when it should be 'rcHover MyTestClass'.

[Vasil]

Hello Osama,

Indeed it is not the same bug. The issue that you are having is currently a limitation in the RadCalendar. If
you add class for the Cell it will remain only for the Enabled state. And on hover it will apply the hover style.
You could try to implement your logic ClientSide on the Client OnDayRender. See the JavaScript in this demo that might help you to achieve it.

In future we are planing to implement mode in which all styles will be added instead of replaced.
In this way, during focus you will see 'rcSelected MyTestClass'. and during hover you will see 'rcHover MyTestClass'. If hover selected cell it will be even 'rcSelected rcHover MyTestClass'. Hopefully for the next major release we will have this implemented.

Kind regards,

The javascript solution doesn't work neither, another Telerik JS function (the one that replace the css class on 'onmouseout') overrides my own fuynction (your event must be triggered after mine).

If you decide the change this behaviour (like you said, add our css class rather than replacing it) that would be brilliant and solve quite a lot of issues. Honnestly, all the other telerik controls work like that so I don't see why the RadCalendar would be an exeption. 

Any idea of when the next release is going to happen? Shall I worry about it and work on a solution myself or is this new functionality really going to happen in the next release? PLEASE take in consideration that this is important for the relase or my product.
I can wait for the next release only if you can guarranty that is behaviour is going to happen.

Do you want me to open a support ticket? May be it will be looked at in higher priority?

Regards.

[Neil]

I'm just thinking, maybe I can override the 'onmouseout' event?

[Vasil]

Hello Osama,

The next release will be around mid of February. (The service pack of the current release will be sooner, it will not include the new functionality).

Overriding the onmouseover might work, but I could not guarantee. Currently we don't have any know tested workaround for the issue.

Kind regards,
