In a web application, if I select the control and change the Date value, then delete the date value (all from the property tool window) the rendered HTML (in the Source view) shows 'Value=""'. How can I get the control to remove the Value property in the
html source view when the value is empty (not DateTime.MinValue, which is what Nothing is converted to)?

What does that mean？Do you want to not show the property in the aspx codes of the control in HTML？
I would rather the Value property be removed with the Value is an empty string, since really, the Value is a Date property and not a String. DefaultValue usually takes care of this, but since it's a Date, doesn't work out so well from what I've tried. I would like it to go back to the following when the date is deleted:

What I mean is, when I first drag and drop the control on the page, I get something like this:
Then when I change the Value property in the property tool window to a date and press enter, I get this:
When I select the date in the property tool window and delete the date and press enter, I end up getting this:
