.NET Forum / Languages / C# / September 2007DateTimePicker and visibility to Min/Max Dates.
Greetings group, I have a situation where I'd like to visibly see disabled dates on a DateTimePicker. Frequently the Min and Max dates in the picker will be set only to days apart, and so I would like this to be reflected in a way other than it simply failing to select when they click. It seems like this would be doable with a MonthCalendar control, however the DateTimePicker itself doesn't seem to expose an internal MonthCalendar, nor does it provide any kind of hihglighting options. I'm open to any/all crazy suggestions. :) Chris. Hi, > Greetings group, > [quoted text clipped - 7 lines] > > I'm open to any/all crazy suggestions. :) IIRC you can control how each cell will looks like in the control. You could set the CssClass to a style that the text is not visible. So it will be "invisible" This must be for a WinForm, I don't see CssClass. > Hi, > [quoted text clipped - 13 lines] > could set the CssClass to a style that the text is not visible.

My bad, I though it was for a web app. But still the idea is valid, just to try to have the same color of the font/background in the needed cells. > My bad, I though it was for a web app. > > But still the idea is valid, just to try to have the same color of the > font/background in the needed cells. The trouble is visibility to those cells. Chris. Yes the Idea is valid in theory and thin air. I don't see how to control each individual day format. It is not available like on in the web control. > Hi, > [quoted text clipped - 4 lines] > But still the idea is valid, just to try to have the same color of the > font/background in the needed cells.

You will have to do it yourself. Before doing that I advise you to google aroudn for projects, this may be asked and answered before. For example a query of datetimepicker color in google returned this: http://www.codeproject.com/cs/miscctrl/extended_datetimepicker.asp Otherwise take a look at some commercial options like Infragistics. Infragistics implement a kind of CSS for windows controls that is super cool, You can change the look of your application on the fly and the controls are very configurable > You will have to do it yourself.

I was just wondering if there was some kind of simpler method that I had somehow missed. > Otherwise take a look at some commercial options like Infragistics. > Infragistics implement a kind of CSS for windows controls that is super > cool, You can change the look of your application on the fly and the > controls are very configurable Looks cool, I may have to see if management will go for it.

Are you saying MinDate and MaxDate properties will not do it for you? > Greetings group, > [quoted text clipped - 9 lines] > > Chris. > Are you saying MinDate and MaxDate properties will not do it for you? Nope, try it yourself. Just add a DateTimePicker and a MinDate and MaxDate, and for me, by default, it simply means the user can't click those dates once the MonthCalendar control has dropped down. Visibly there isn't a difference between a valid date in the current month and an invalid date in the current month. Chris. Okay so what you want to do with the invalid dates is to make them invisible. There must be a way to override the rendering, but I don't see how now. >> Are you saying MinDate and MaxDate properties will not do it for you? > [quoted text clipped - 5 lines] > > Chris. this might help or give you some direction http://www.codeproject.com/cs/miscctrl/extended_datetimepicker.asp >> Are you saying MinDate and MaxDate properties will not do it for you? > [quoted text clipped - 5 lines] > > Chris.
