Deleting everything in the cell still does not evaluate to a NULL Thanks Ah, you need the VALUE in the current cell... I guess the experts are laughing at me, but I'm not the least bit impressed with I've put in over 8 hours just trying to validate a stupid cell on a Data Grid View. :) :) Thanks for your help, I'll happily give you the points. Beim Betätigen des Close buttons (X) wird es einfach übersprungen.
If I ever bump into Bill Gates at a cocktail party, I'm going to ask him what the hell he was thinking when he created the dgv :) :) :) :) No worries, As for what was he thinking...
I would like to check for the validity of a date (such as a February date for leap year) in C#. What I want is to validate the date for any month, day and year; furthermore, the day is to be validated against a particular month and year (not just within 1 - 31). Wellens: You deleted my identical response because you said "Try Parse Exact" was already suggested. Today; Date Time new Date; bool result = Date Time. To Short Date String(), out new Date); // true means correct date bool result1 = Date Time.
