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).

You could instead implement the INotify Property Changed interface (for notifications) and the IData Error Info interface (for validation). That is why we made it public -- so you can place it in your view model and do MVVM. Regards, Ross the Telerik team Hi, Follow up: In case you do not need to perform any editing, i.e. Rad Data Pager will also do server-side paging (Skip and Take).

You can try this as well comletely eliminating the need for our control.

How to efectively validate data entry inside a Data Grid View. Late Validation: This validation is performed after the user is done entering data.

The problem I am having is how to refactor logic to an external class, that has references to the winform controls.The very first thing you need to do is make sure that your form is not responsible for retrieving the Data Table. The Presenter should be responsible for providing it to the View.定义单元格验证要求:验证错误后焦点不离开。实现:单元格的验证可以使用dgv_details_Cell Validating事件。验证不通过时调用e. Form All following code is part of private string last Edited Cell Value; private void dgv Replenish_Cell Begin Edit(object sender, Data Grid View Cell Cancel Event Args e) private void dgv Replenish_Cell Validating(Object sender, Data Grid View Cell Validating Event Args e) private void dgv Replenish_Cell Clicked(object sender, Data Grid View Cell Event Args e) private void dgv Replenish_Cell Formatting(object sender, Data Grid View Cell Formatting Event Args e) private void dgv Replenish_Cell Value Changed(object sender, Data Grid View Cell Event Args e) The truth is, it's really very hard to refactor this code out of the code behind once it's been written like this.I would suggest that you start writing your tests first, for now at least.
