Validating datagridview Chat naked sex open
if i want only numbers in a particular cell in the datagrid how can i do it. ID, Name, Phone number I want to validate this phone number field.if user enter a some other values than a number i want to give a error message. I think that could be the problem and that I'm not telling it the correct column.Although I would like to understand this better than I do.The other type of input validation can be used to reject any unacceptable data, for example a zero value in a field that must be greater than or equal to one, or an inappropriate string. The example below uses the Column Changing event because the unacceptable value is disallowed for the "Product" column in particular.This is done in the dataset by writing an event handler for the Data Table. You might use the Row Changing event for checking that the value of an "End Date" column is later than the "Start Date" column in the same row. I do have a visual basic 2005 - wrox book and 2 programing in visual basic books by Bradley and Millspaugh which I refer to alot. ----------------------------------------------------But just a little info on my situation.
