I want to have a calendar where a date selection causes a user to be redirected to an appropriate page. So, I set AutoPostBack="true" for the RadCalendar control and handle the SelectionChanged event on the server-side. Although, if user navigates from the page back to the calendar and hover the mouse over the previously selected date it appears selected.
How to replicate...
Markup:
Codebehind:
When the user presses the browser back button I want the calendar to be "fresh" and not have the hidden selection.
Thanks.

| <telerik:RadCalendar ID="RadCalendar1" runat="server" AutoPostBack="true" /> |
| </form> |
| </body> |
| </html> |
Codebehind:
| Private Sub RadCalendar1_SelectionChanged(ByVal sender As Object, ByVal e As Telerik.Web.UI.Calendar.SelectedDatesEventArgs) Handles RadCalendar1.SelectionChanged |
| Dim d As String = e.SelectedDates(0).Date.ToShortDateString() |
| RadCalendar1.SelectedDates.Clear() |
| Response.Redirect("WebForm1.aspx?date=" + d) |
| End Sub |

Hi Jan,
Try attaching OnLoad client event to RadCalendar to deselect the dates when clicking the back button in browser. Give a try with this and see whether it helps.

JavaScript:

| function OnLoad(sender, args) |
| { |
| var dates = sender.get_selectedDates(); |
| if(sender.get_selectedDates().length != 0) |
| { |
| sender.unselectDates(dates); |
| } |
| } |

Hi Shinu,
The suggested idea you provided causes a SelectionChanged event to be raised (where the SelectedDates collection is empty) on the back button being pressed which is undesired. Is there a workaround to this?
Thanks.

Hello Jan,
You can just add a check to the SelectionChanged event handler to verify that the SelectedDates collection has any members like this:
