I think I found the problem. My "regional settings" is set to Turkish. And I think rad library converts recurrence types from lower case to upper case. When I select daily recurrence, it converts it from "daily" to "DAİLY" (where in English regional settings, it is supposed to be "DAILY"). Then I think this causes the problem.

Does anyone have any suggestions to solve this problem?

Hi Afsar,

Thank you for reporting the issue and finding the actual cause. We're a bit ashamed that we've fallen for the classic Turkish I problem. We'll fix this right away and the fix will be available in the next internal build.

As a token of our gratitude for your involvement, your Telerik points have been updated.

Hello Tsvetomir,

Thank you for your interest and the points you gave to me. But I had to continue my project and at last, I found my own solution. Those who have the same issue can refer to this.

A revision of Scheduler's FirstLook example : http://www.zumodrive.com/share/3UZeYzA4OT

A sample screen-shot is attached.

The followings are the steps to prevent this problem.

1. The page must have English culture.

At the top of the page the culture can be set as : <%@ Page Culture="en-US" UICulture="tr-TR"

Note that the UICulture property can be set to Turkish culture. But the Culture property has to be set to English culture.

2. At the Page_Init event the culture property of calenders, schedulers, etc. must be set to Turkish culture.

For example,

RadCalendar1.CultureInfo = getTRCulture();
RadCalendar2.CultureInfo = getTRCulture();
RadScheduler1.Culture = getTRCulture();

Where getTRCulture() is

private CultureInfo getTRCulture()
{
return CultureInfo.GetCultureInfo("tr-TR");
}

3. While coding, programmer can prefer to code according to Turkish culture instead of English culture. He might prefer to write DateTime.Parse("31.12.2009") instead of DateTime.Parse("12/31/2009"). To do that the culture setting must be changed to Turkish at the beginning of the code and it must be changed to English again at the end of the code.

For example,

try
{
setThreadCultreTR();
DateTime dtSelectedDate = DateTime.Parse("31.12.2009"); //instead of "12/31/2009"
RadScheduler1.SelectedDate = dtSelectedDate;
RadCalendar1.SelectedDate = dtSelectedDate;
}
catch (Exception ex)
{

}
finally
{
setThreadCultreEN();
}

Where setThreadCultreTR() and setThreadCultreEN() are

private void setThreadCultreTR()
{
Thread.CurrentThread.CurrentCulture = getTRCulture();
}
private void setThreadCultreEN()
{
Thread.CurrentThread.CurrentCulture = getENCulture();
}

And where getENCulture() is

private CultureInfo getENCulture()
{
return CultureInfo.GetCultureInfo("en-US");
}
