I have tried the below code on datagrid View Cellvalidation event but its not working.

I want that whenever user presses anyother key than a number key(ex:1,2,3,4....)than immediately i should get a messagebox that only numbers allowed.

From inside the Form Designer, you should see a very small triangle at the upper right-hand corner of the Data Grid View control. For example, if the Units On Hand column can never be a negative number,you could write a validating rule that looks to see if the value is negative prior to committing the changes to that row.

Click on this triangle to select the data source that was created for you when you ran the Data Source Conversion Wizard. You can use the Error Provider class to display the problems detected during validation.

Let's say that you have a Microsoft Access database that you plan to use in your program. For example, all columns are aligned to the left and have have no formatting.
