DateTimePicker and MinDate

[Jason Parrish]

I am encountering 2 issues with the DateTimePicker and MinDate.

1. I can not select the minimum date from the dropdown picker.  For example, if MinDate is 12/10/2010, I am not able to select that as the date, instead it closes the dropdown and enters nothing in the textbox.  When this occurs, I am unable to type in the textbox until I pick another date.  This does not happen if I click on a date earlier than the MinDate, e.g 12/8/2010.
2. If I tab into the textbox, I can type in a date earlier than the MinDate.  The value does not change, but the display does.  Not very consistent UX.

I am using the latest version.

Thank you!

Hi Jason,

For your first issue, I can replicate this with the following code and I'd say that this is a bug

Me.RadDateTimePicker1.Value = New DateTime(2010, 12, 10, 0, 0, 0)
Me.RadDateTimePicker1.MinDate = New DateTime(2010, 12, 7, 0, 0, 0)
Me.RadDateTimePicker1.MaxDate = New DateTime(2010, 12, 12, 0, 0, 0)

however, as a workaround, it doesn't happen if you do this (doesn't clear, just doesn't allow selection for the 7th)

Me.RadDateTimePicker1.Value = New DateTime(2010, 12, 10, 0, 0, 0)
Me.RadDateTimePicker1.MinDate = New DateTime(2010, 12, 7, 0, 0, 1)
Me.RadDateTimePicker1.MaxDate = New DateTime(2010, 12, 12, 0, 0, 0)

hope that helps
Richard

Thank you.  I took what you discovered for a workaround, and discovered that a better workaround would be to do this.

  Me.RadDateTimePicker1.Value = New DateTime(2010, 12, 10, 0, 0, 0)

        Me.RadDateTimePicker1.MinDate = New DateTime(2010, 12, 6, 23, 59, 59)

        Me.RadDateTimePicker1.MaxDate = New DateTime(2010, 12, 12, 0, 0, 0)

  Me.RadDateTimePicker1.Value = New DateTime(2010, 12, 10, 0, 0, 0)

        Me.RadDateTimePicker1.MinDate = New DateTime(2010, 12, 6, 23, 59, 59)

        Me.RadDateTimePicker1.MaxDate = New DateTime(2010, 12, 12, 0, 0, 0)

     Me.RadDateTimePicker1.Value = New DateTime(2010, 12, 10, 0, 0, 0)

        Me.RadDateTimePicker1.MinDate = New DateTime(2010, 12, 6, 23, 59, 59)

        Me.RadDateTimePicker1.MaxDate = New DateTime(2010, 12, 12, 0, 0, 0)

     Me.RadDateTimePicker1.Value = New DateTime(2010, 12, 10, 0, 0, 0)

        Me.RadDateTimePicker1.MinDate = New DateTime(2010, 12, 6, 23, 59, 59)

        Me.RadDateTimePicker1.MaxDate = New DateTime(2010, 12, 12, 0, 0, 0)

     Me.RadDateTimePicker1.Value = New DateTime(2010, 12, 10, 0, 0, 0)

        Me.RadDateTimePicker1.MinDate = New DateTime(2010, 12, 6, 23, 59, 59)

        Me.RadDateTimePicker1.MaxDate = New DateTime(2010, 12, 12, 0, 0, 0)

     Me.RadDateTimePicker1.Value = New DateTime(2010, 12, 10, 0, 0, 0)

        Me.RadDateTimePicker1.MinDate = New DateTime(2010, 12, 6, 23, 59, 59)

        Me.RadDateTimePicker1.MaxDate = New DateTime(2010, 12, 12, 0, 0, 0)

Me.RadDateTimePicker1.Value = New DateTime(2010, 12, 10, 0, 0, 0)
Me.RadDateTimePicker1.MinDate = New DateTime(2010, 12, 6, 23, 59, 59)
Me.RadDateTimePicker1.MaxDate = New DateTime(2010, 12, 12, 0, 0, 0)

This would allow you to select the 7th correctly as expected.

However, due to the allowing the text to be cleared (as mentioned in my other post), I have replaced the datetimepicker with the masked textbox for now.

I will continue to find a workaround to prevent the text from being cleared, perhaps preventing the DEL key from being pressed would be the first step.

Again, thank you.
