DateTimePicker + DataBinding + Null-Value: THE solution?Hi,
I'm looking for a DateTimePicker that supports 100% databinding (and support null-values)... It's a shame that the normal control doesn't, but when searching on the internet, I didn't find any solution that works without problems. Does anybody know where I can find an inherited DateTimePicker that supports databinding and nulll-values? Any links, sample code etc would be really appreciated! It can be for VB.NET 2005, in case that would make the task easier... Thanks a loty in advance, Pieter Pieter,
You can take this sample, and than use instead of the textbox the datetimepicker. You have to change a little bit. The datetimepicker has to bind to the property "value", while in some places where now the values are returned as text should be returned as value. (Not to string by instance or and instead of "" nothing) http://www.vb-tips.com/default.aspx?ID=c4832a2a-2b95-4ded-93d9-4deb7fa4a0b8 I see that I use "datum" that is Dutch for date, maybe I will change that in future to make it less confusing for you. I hope this helps, Cor Show quoteHide quote "Pieter" <pietercou***@hotmail.com> schreef in bericht news:%23UR4oY3OGHA.740@TK2MSFTNGP12.phx.gbl... > Hi, > > I'm looking for a DateTimePicker that supports 100% databinding (and > support null-values)... > It's a shame that the normal control doesn't, but when searching on the > internet, I didn't find any solution that works without problems. > > Does anybody know where I can find an inherited DateTimePicker that > supports databinding and nulll-values?

So correct usage is
to say "the data *are* wrong" or "the data *are* in that file." But, nobody does that nowadays. "Data" is treated as singular noun. This was a pet-peeve of an overly intellectual boss of mine a few years ago. Show quoteHide quote "Jay B.

Instead it's mainly used equivalently to "date" in English. -- M S Herfried K. Wagner M V P <URL:http://dotnet.mvps.org/> V B <URL:http://classicvb.org/petition/> Jay,
Thanks, I did not know that and find it fine to know. In Dutch Datum is only used as a singulair for Date. The pluriform of that is official Data. Although most people use Datums now to make it not more confusing as it already is. Probably a nice shift in of the original meaning of the word. I assume in English because for what Herfried wrote about the German language. German is the second from the most important Germanic languages while Dutch is the thirth (before you misunderstand English is the first in that). And because I like this, did I find your comment fine to know. Maybe I go examine this deeper. Cor Show quoteHide quote "Jay B.

Belgium the people actually do know that they should use "data" as the plural of "datum" which means "date" in english :-P "Pieter" <pietercou***@hotmail.com> schrieb: Untested:> I'm looking for a DateTimePicker that supports 100% databinding (and > support null-values)... <URL:http://www.grazioli.ch/Blog/PermaLink.aspx?guid=c4a63d35-71f9-4b02-9de7-0c87e5b1c770> Nullable DateTimePicker <URL:http://www.codeproject.com/cs/miscctrl/Nullable_DateTimePicker.asp> (For a translation to VB.NET, take a look at the comments section of the page.) You may want to set the 'ShowCheckBox' property to 'True' and use the checkbox as a null value indicator (if 'Checked' is 'False', no date is selected). Notice that the 'ShowCheckBox' property is flawed and thus this is not the best way. -- M S Herfried K. Wagner M V P <URL:http://dotnet.mvps.org/> V B <URL:http://classicvb.org/petition/>
