    When using a RadCalendar and if a user clicks on the currently selected date, the SelectedDate value of the RadCalendear will change to the RangeMinDate.  I'm currently using version 2011.3.11.1219. Please let me know if I'm missing something or a common work around for this.

    Thanks,
    Chris

    Hi Chris,

    Thank you for contacting us.

    This is the default behavior of RadCalendar. When you click on a cell that is selected, it is being deselected, hence the SelectedDate equaling the RangeMinDate. However this cell remains focused and visually appears as it was selected. If you do not want to deselect a date, you can subscribe to the SelectionChanged event and handle it the following way:
    void radCalendar1_SelectionChanged(object sender, EventArgs e)
    {
        if (this.radCalendar1.SelectedDate <= this.radCalendar1.RangeMinDate)
        {
            this.radCalendar1.SelectedDate = this.radCalendar1.FocusedDate;
        }
    }

    I hope you find this useful. Do not hesitate to write back if you have any additional questions.

    All the best,
    Ivan Todorov

    Hi Ivan Todorov,

    But when i click back on RangeMinDate, an exception issued is that "Cannot evaluate expression because the current thread is in a stack overflow state."

    Please help me to solve my problem.

    Thanks,

    Manh

    Hi Mahn,

    This could happen only when you try to select the RangeMinDate. To overcome this, you should modify the code as shown below:
    private void radCalendar1_SelectionChanged(object sender, EventArgs e)
    {
        if (this.radCalendar1.SelectedDate <= this.radCalendar1.RangeMinDate &&
            this.radCalendar1.SelectedDate != this.radCalendar1.FocusedDate)
        {
            this.radCalendar1.SelectedDate = this.radCalendar1.FocusedDate;
        }
    }

    I hope this will help you. Should you have any further questions, do not hesitate to contact us.

    Kind regards,
    Ivan Todorov

    Hello Ivan,

    I had set my radcalenders min date and max date.but still it didnot reflect in the UI.

    below is my code:

     <telerik:RadCalendar runat="server" ID="dpDateOfBirth" OnSelectionChanged="dpDateOfBirth_SelectionChanged" MinDate="01/01/1900" RangeMinDate="01/01/1900" RangeMaxDate="12/31/2000" EnableMultiSelect="false" FastNavigationStep="12" AutoPostBack="true" TitleFormat="MMMM yyyy"  Visible="false">
     </telerik:RadCalendar>

    Hello,

    Your question seems to concern our ASP.NET AJAX controls, while this forum concerns the Telerik UI for WinForms controls. May I please ask you to post in the ASP.NET forum in order to get adequate response.
