Problem with two controls sharing the same data source

Question

I am creating a winforms application, I have two comboboxes that have the same data source, the data source is DataTable. Now, when I select a value in one comboBox, the value of another comboBox also changes. Is there a way to change it without affecting others?

Answer 1

In this type of scenario, you can create two different sources of binding, bound to each of your lists. If you set a property DataSourcefor each of the binding data sources DataTable, then your combined fields will work independently, and the same data will be displayed.

:

// Initialization of the binding sources(assuming dataTable is a populated DataTable)
bindingSource.DataSource = dataTable;
bindingSource2.DataSource = dataTable;
