Datagridview cell validating
-Sometimes the answer to your question is the hack that works I changed the textboxes to variables on your code and ran it fine and it correctly changed dvg Test but that still didn't help me change the cell value.
Also this approach allows the user more flexibility.You'll be able to ask any tech support questions, or chat with the community and help others. I have tried the below code on datagrid View Cellvalidation event but its not working. You might want to handle this for a number of reasons: to enable a save button, to change the appearance of selected items, to display a pop-up window, or to check for consistency against other choices.It turns out that this is trickier than it might seem and doesn’t work great out of the box from . Once you start fighting your own code, it turns into a mess, you have to consolidate the logic and hope you didn't miss a way to bypass your checks.
You may have to move all the logic related to validating that data from the Validating, to the Cell Leave, and just assume that the data there is good.
In order to implement Immediate validation, the event Cell Validation must be handled Ex The validation to check if the cell is in edit mode is very important. For the Late Validation, there must be an event that is perform once the user finish entering data.
In the implementation of this event, we would have to go through all the rows that have any info on them and perform the validation required, setting the appropiate error messages in the cell.
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.
