While you are correct, prior to SQL 2008, SQL Server could only go back to 1753. Microsoft added DATETIME2 which goes back to 01/01/01. While 1980 is great as mindate for most people, anyone dealing with "people" as an entity would soon realize that birth dates need to go back further than 1980. Having 1980 as the default minimum date doesn't make a lot sense (it doesn't even match against the SMALLDATETIME).

My purpose for using the built in DateTime.MinDate is that I am too lazy to code my own minimum date throughout the system (primarily). I wouldn't expect to use dates before 1900, but I do need to go back that far. My second use is as an uninitiated date where I don't want to or can't use a NULL value (because I want to simplify access). This occurs in date time segments and again in uninitialized dates (e.g. initial effective date, last paid date) where I don't want to use a NULL.

So, a lot of it is me being lazy in that I don't want to have to worry about the minimum date, but I don't think that makes it any less of a bug. If you accept the DateTime.MinDate as a minimum date when the page is built, and it is used properly when the page is in the browser, the postback should not automatically change my MinDate.

I'm creating runtime a dateinput, but it doesnt accept dates before 1980, how can I configure this for having dates prior to 1980:

    
                        RadDatePicker inputdate = new RadDatePicker(); 
        
                        inputdate.DateInput.DateFormat = "dd/MM/yyyy"; 
        
                        inputdate.DateInput.EmptyMessage = "fecha"; 
        
                        inputdate.DateInput.MinDate = new DateTime(1930,1,1); 
        
                        e.EditControl = inputdate;

Hello,

You can set the MinDate property of RadDatePicker prior than 1980 to accept the required dates.

CS:

    
                RadDatePicker inputdate = new RadDatePicker(); 
        
                inputdate.DateInput.DateFormat = "dd/MM/yyyy"; 
        
                inputdate.DateInput.EmptyMessage = "fecha"; 
        
                inputdate.DateInput.MinDate = new DateTime(1930, 1, 1); 
        
                DateTime minDate = new DateTime(1900,1,1); // Set the MinDate as per your requirement - here it set as 1/1/1900

                inputdate.MinDate = minDate;

-Shinu.

I know it was said that this was fixed back in 2009 but I am experiencing the same issue. I have created a new web project just to test this and I found that setting the MinDate to "01/01/0001" causes the value and MinDate to get set to "01/01/2001". As I tested I found that the lowest MinDate that can be set and works is "01/01/0100". Anything below that does not work. Interestingly enough, setting any daye below 01/01/0100 sets yields different values depending on the year. The framework I am using uses the value "01/01/0001" to represent a null datetime.

Is it possible that this issue has resurfaced back into your latest code?

Thanks,
Kevin

Hi,

I am using the below code, but it wont set my min date.

Can you please let me know how do i fix it?

RadDatePicker radDatePicker = new RadDatePicker();
radDatePicker.ID = "radDatePicker_" + promotionID.ToString() + "_" + dr["S" + s.ForeignID + "_SecondaryRefID"] + "_" + todo.ToDoID.ToString();
radDatePicker.SharedCalendarID = "SharedCalendar";
radDatePicker.Width = new Unit(20);
radDatePicker.Skin = "Modern"; //made changes to Calendar.css file from the Default skin folder
radDatePicker.RadControlsDir = "~/RadControls/";
radDatePicker.DateInput.Style["display"] = "none";
radDatePicker.DateInput.DateFormat = "dd/MM/yyyy";
radDatePicker.FocusedDate = m_Date;
radDatePicker.SelectedDate = m_Date;
radDatePicker.Calendar.EnableMultiSelect = false;
radDatePicker.Calendar.UseColumnHeadersAsSelectors = false;
radDatePicker.ClientEvents.OnDateSelected = "RadDatePicker_DateSelected";
DateTime Mindate1 = new DateTime(1990, 1, 1); // Added by Viral for WWRS-30
radDatePicker.MinDate = Mindate1;

m_Cell.Controls.Add(radDatePicker);
