Asked On November 1, 2002 03:06 AM UTC

Does anyone have a way to allow for "null" date-times with a date picker control. My app has a lot of date fields that are not necessarily populated. I need a way for these to be displayed as invisible... I am sure the answer is staring me right in the face. Thank you,

I have developed a datetimepicker with the same properties as the one in visual studio, but it allows null values when there is no date selected. the way i developed this is access the databinding and update the value of the dataset or datatable or object to null. it works prefectly without a glitch, if you are interested send me an email, and i ll send ou the source code

This is the source code of the null datetimepicker, bind the control to the 'value' property, it will return a null to your binding when there is no valid date on the control.

Hi all, Its easy, u have a ShowCheckBox property for the datetime picker, set it to true at design time, so if the user wants to enter a null date he would uncheck the checkbox and vice-versa if he wants to enter a date. u would have to check in code if the DateTimePicker1.checked == true OR false, based on that u could proceed with ur application. > Does anyone have a way to allow for "null" date-times with a date picker control. > > My app has a lot of date fields that are not necessarily populated.
