Setting selectedDate property of RadCalendar

[Julian]

I have a RadGrid that is using in place editing. One of my columns contains a RadCalendar control. I am setting the selectedDate of the RadCalendar to the value of a property 'ValidDate'.  I'm also setting the value of a Lable to the property 'ValidDate' as a sort of test. Initially when the Grid is displayed the label does have the correct value. However, when the 'edit' is clicked, causing the selected row to go into edit mode, the 'ValidDate' values I assigned to the label within the GridRow is lost.

Can you tell me why the value is lost and possibly how to correctly keep the value so I can set the selectedDate of the RadCalendar?

Thanks,

Here is the aspx code:

Here is the C# code:

            try

                if (returns == null)
                {
                    // Create returns manager
                    returns = ReturnsFactory.CreateReturns();
                }

                // Set 'Year'
                validDate = new DateTime(Convert.ToInt32(holidayYear.SelectedValue), DateTime.Now.Month, DateTime.Now.Day);

                // Fetch Holidays
                Holidays holidays = (Holidays)Session[Constants.Session.PageData];

                // Get Holidays if they are not already in the session
                if (holidays == null)
                {
                    holidays = returns.GetHolidays(currentHolidayYear);
                    Session[Constants.Session.PageData] = holidays;
                }

                holidayRadGrid.DataSource = holidays.Values;
                holidayRadGrid.DataBind();

                // Set correct year to be used for the column HolidayDate's Header Text
                holidayRadGrid.MasterTableView.GetColumn("HolidayDate").HeaderText = holidayYear.SelectedValue;
                holidayRadGrid.Rebind();

Hi Julian,

I am not sure where exactly you are calling the BuildTable function. If you are using the NeedDataSource event try calling it there . Also remove the DataBind() method in the BuildTable function.

Thanks

Shinu, Thank you very much. That solved my problem.
