How to: Share Bound Data Across Forms Using the BindingSource Component
You can easily share data across forms using the xref:System.Windows.Forms.BindingSource component. For example, you may want to display one read-only form that summarizes the data-source data and another editable form that contains detailed information about the currently selected item in the data source. This example demonstrates this scenario.
Example
The following code example demonstrates how to share a xref:System.Windows.Forms.BindingSource and its bound data across forms. In this example, the shared xref:System.Windows.Forms.BindingSource is passed to the constructor of the child form. The child form allows the user to edit the data for the currently selected item in the main form.
Note
The xref:System.Windows.Forms.BindingSource.BindingComplete event for the xref:System.Windows.Forms.BindingSource component is handled in the example to ensure that the two forms remain synchronized. For more information about why this is done, see How to: Ensure Multiple Controls Bound to the Same Data Source Remain Synchronized.
