That said, I prefer to use the Value Changed event (Cell Value Changed for DGV) to do my validation. If I need the user to have time to complete the entry, then I sometimes include a timer that is (re-)started on each Value Changed and executes the validation a short time later. Hi there, I have a question regarding datagridview in C#. Minimum Date Time; This is to ensure the limits are OK before the value is set and prevents an Argument Out Of Range error.I have done the validateion for the datagridview in the cellvalidating event. so there is never any chance of an invalid entry in the first place. Hi there, I have a question regarding datagridview, I add data to the datagridview in an interface and all the validation for the datagridview cell is in the datagridview cell validating event for the datagridview. If the row does not pass validation, set the Row Col Event Args. Canceling this event prevents the Row Validated event from occurring, and also prevents the user from leaving the invalid row.
There are two ways to manage unwanted execution of event handlers. Data Grid View Cell Validating Event Args' does not contain a constructor that takes '1' arguments" what is the solution for this???????Something there is causing the cell validating event to fire. [Edit] The validating event is firing because focus is being moved from the DGV to the button.Since you have not added your new row yet it should validate OK.If I need the user to have time to complete the entry, then I sometimes include a timer that is (re-)started on each Value Changed and executes the validation a short time later. Today;" is there any way for this in the datagridview cell fro the calender column thanxxxxxx However I found that if I set different limits for each row then an error sometimes occurs when moving to edit another row. Data Grid Cell validation Cell; private void data Grid View1_Cell Value Changed(object sender, Data Grid View Cell Event Args e) // validation timer set to (250 ms ish) private void timer1_Tick(object sender, Event Args e) I generally prefer to prevent the user from entering an invalid value by always using Combos, Up Down number thingies with max min set, etc. :) hey, i am validating the calender column in the datagridview can i make it so that the user can't select a date that has passed???
