Datagridview cell validating cancel


18-Feb-2020 12:32

im not able to see the drop down menue of the combobox anymore (it was working fine before) the combobox is handelt by the event "Selected Index Changed" but this is not triggert anymore because i cant select anything. Greetings Holly The Cell Validating event has a specific role. but everytime the cellvalidating event is fired and i cant do anything else than typing in my dgv... so i click on the little button to bring up the content. then there occures an error or not (depending on my input...) and now i want to make use of my combobox.I recommend setting the Cancel property to true for invalid data as then the user focus will remain in cell 2. (inside your column test) events are used to help stop the user from leaving a cell with a bad value.I recommend setting the Cancel property to true for invalid data as then the user focus will remain in cell 2. (inside your column test) hey thankxx but the thing is i have to click on another place in the datagrid view to trigger the event.so if i select invalid date i have to click another place in the datagrid view for the error msg to to i avoid this and make the event trigger after the cell value is beign selected?????Every now and then cell values of Data Grid View have to be validated.

i and using the dgv Actions_Cell Validating event,but the thing is i want to validate the cell after the cell value has been selected.the code i have written does the validation when i click on another cell in the datagrid view.i have written the code to validate the datagridview cell 2 , but whe i clicl cell 3 only the validation event is triggered for cell 2. how can i make the validation trigger so that the value of the current cell is seelcted. events are used to help stop the user from leaving a cell with a bad value.The Event Args usually has a Cancel property that if set to true will block the user from leaving the data entry field (cell, textbox, etc.).

They are only triggered when the user tries to leave a field because only then can we be certain that the user has finished entering the value.In my initial test to achieve what the OP was asking for, I did notice however that I was not able to close the form when on a cell that was incorrect.
