Translation only works partially with RadSchedulers

Dear Telerik Team,

I'm current using Q1 2011 SP with VS2008. When applying the example in the help file for the RadScheduler to translate the RadScheduler strings and in example:

RadSchedulerLocalizationProvider.CurrentProvider =

New CustomSchedulerLocalizationProvider

Everything appears translated in the local language except the days of the week in RadScheduler's header columns which are still in English:
Monday, Tuesday, Wednesday...
Is it possible to programmatically change the text of these header columns?

Best regards,
Alain

Default Backcolor for Button Fill Element

Hello,

I am using a lot of Rad buttons in my application. I change the back color of the buttons based on some conditions the following code:

.ButtonFillElement.BackColor = Color.LightGreen;
.ButtonFillElement.GradientStyle = Telerik.WinControls.GradientStyles.Solid;
.ForeColor = Color.Black;

My questions is how do i set these properties back to the default ones within code. I want the buttons to get the default theme of the application when the condition turns false.

Thanks,
Pawan

RadComboBox does not show focus ques

I have several RadComboBoxes (Q2 2010). I have AllowShowFocusQues set to True, TabStop set to true & DropDownStyle set to DropDownList.

When I tab onto the field there is no change in the appearance of the combo box. I know I have focus because I can use the arrow keys to move through the list. I would have thought may do something like the DropDownList or button with a dotted box just inside the control's border.

The list does include a blank item that is shown initially. However even if I select a different item from the list, tab off and then back to the combo box there is no indication that the combo has focus.

Thanks!

Memory Leaks

Hello,
We have a problem using the telerik controls on a form, a memory occupied problem, but never freed, the form uses the following controls:
• 3 DataTable.
• 1 DataSet.
One of the DataTable is populated with 10,000 records and the other 2 with 5 records, more records DataTable is populated as follows:

dtDataTable.Add("Ide", typeof(int));

dtDataTable.Columns.Add(

"Nom", typeof(string));

foreach (Objeto oObjeto in ArrayObjetos)

{

DataRow drRow = dtDataTable.NewRow();

drRow [

"Ide"] = oObjeto .Ide;

drRow [

"Nom"] = oObjeto.Name + " " + oObjeto.LastName;
dtDataTable.Rows.Add(drRow );

}

The 15 MB memory increases by this load but the release (close) is in use 8 MB of those 15.
The Close () the form we make the following:

if(dtDataTable != null)

dtDataTable.Clear();

dtDataTable=

null;

if(dtDataTable1 != null)

dtDataTable1.Clear();

dtDataTable1=

null;

if(dtDataTable2 != null)

dtDataTable2.Clear();

dtDataTable2=

null;

The question is, We are releasing resources correctly or the problem may be the way I'm filling?
Thank you very much.

is in use 8 MB of those 15.The Close () the form we make the following:if;if;if;

Border & backgroundcolor RadScrollablePanel

I'm using the RadScrollablePanel in a DocumentWindow to have themable scrollbars when the content doesn't fit. Afaik the scrollbars of the DocumentWindow aren't themeable (yet).

Is it possible to have the panel to be "invisible", that is: disable border and backgroundcolor equal to the background color of the DocumentWindow?
