Error icon in date selection (with minDate set)

[Joe]

I'm using two Calendar date/time pickers to set a date range that is used for a SQL DB lookup. I only want the user to be able to select a date that is no more then 30 days from the current date/time in both date pickers. The max date is always today's date/time.

I can get the calendar to only allow 30 days from today but it produces an error  if I choose the last available date (today - 1 month).

The code that I am using is as follows:

	Protected Sub RadDateTimePicker1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadDateTimePicker1.Load
	Dim dt As New DateTime()
	dt = RadDateTimePicker1.MinDate
	dt = Date.Now.AddMonths(-1)
	RadDateTimePicker1.MinDate = dt
	RadDateTimePicker1.MaxDate = Date.Now
	End Sub
	Protected Sub RadDateTimePicker2_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadDateTimePicker1.Load
	Dim dt As New DateTime()
	dt = RadDateTimePicker2.MinDate
	dt = Date.Now.AddMonths(-1)
	RadDateTimePicker2.MinDate = dt
	RadDateTimePicker2.MaxDate = Date.Now
	End Sub

 

Any suggestions on how to prevent the error icon (triangle) and only allow 30 days from the current date/time?

 

Thanks,

Joe

Hi Joe,

I am sending you a small runnable application which demonstrates described behavior.
Please give it a try and see if it works for you.

Thanks for the code example. I loaded (and ran it).

It contained two date pickers. I am guessing to demostrate different methods?

The code in your fist example:

	DateTime dt = new DateTime();
	dt = RadDateTimePicker1.MinDate;
	dt = System.DateTime.Now.AddMonths(-1);
	RadDateTimePicker1.MaxDate = System.DateTime.Now;

Doesn't appear to restrict the user from selecting any date.

The second date picker code:

	DateTime dt = new DateTime();
	dt = RadDateTimePicker2.MinDate;
	dt = (new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day + 1, 0, 0, 0)).AddDays(-30);
	RadDateTimePicker2.MinDate = dt;
	RadDateTimePicker2.MaxDate = System.DateTime.Now;

Does restrict the user to 30 days from today's date.

Was that what you were trying to demostrate?

Also, when I added the code in line 3, I am restricted to choosing a date 30 days from today but I still get the error (triangle icon in place of the date).

Thanks,
Joe

Hi Joe,

I am sending you a modified project, which handles the desired functionality.
Also note that two DatePickers restrict the user from selecting any date.
Give it a try and see how it goes or if I am leaving something out.

I hope this helps.

All the best,

Tat appears to have done the trick. I'll compare the two code samples you supplied to figure out the difference!

Thanks!
