Datagridview cellvalidating editingcontrol

If you decide later (once you have an idea of how to better design your code), to test after the fact, that's fine.The important thing right now is to separate the concerns. It's more or less the default design pattern for Win Forms.The problem I am having is how to refactor logic to an external class, that has references to the winform controls.

To make it more clear when I press Enter for the second time. A: If you want take input directly in datagridview, column of string type takes any input but Data Grid View default error dialog is shown when making invalid input i-e 123a for integer type column that asks to handle the Data Error event of datagridview . Data Grid View Cell Validating Event Args) Handles Data Grid View1. So you can use Cell Validating event of Data Grid View to validate integer type column as well as other. Cell Validating Dim cell As Data Grid View Cell = Data Grid View1. For more information about handling events, see NIB: Consuming Events.Data Grid View Cell Validating Event Handler Data Grid View Cell Validating Event Args Cell Validated Data Grid View Cell On Cell Validating Data Grid View Class System. I want to refactor this code that is currently in a partial Form Class and deals with edits made on certain cells in a datagridview (in this case called dgv Replenish).
