Tom, i make load data in form activated and it's working successfully. I make it before you reply. Thnx for you reply

Hi Don,

You have several options on reloading your data, you should choose the one that best suits your situation.

• If you want to reload the entire data source to just make sure you have the latest version, you can use the following techniques:
  • Provide a toolbar button for your end users to click and then call your Load Data method.
  • Call the Load Data method from the Form Activated event (this is what you are doing now)
  • You can write some custom logic that checks the back end and if you determine that there are significant changes, you can reload the data at that point.
• If you do use some kind of logic to determine if there are some changes, you can also fetch just the changed records and then update the actual data source that is bound to WinGrid. If you are using an IBindingList implementation (e.g., a generic BindingList of objects), any changes made to the data source itself will automatically reflect in the grid without having to reload the entire collection.

The choice is up to you based on what works best in your situation.

Yeah, i mean to refresh it when i click on form. I solve it with Form_Activated i call function to FillGrid. Thnx for reply Jason
