I need to create a Windows Form with two DataGrids. On the right, there is a DataGrid which displays one selected table. Editing is disabled in this table. But selecting a row is possible. I use tow dropdowns to set up my select command for the database. On the left side I have placed a smaller DataGrid for editing items from the main table on the right.

A user should be able to click a row to select it. The content of the row should be displayed in the smaller DataGrid on the left. Like an Key-Value-Editor. The table has a column "Key" and a column "Value". The keys are the column titles of the DataGrid on the right. And the values are the content of the currently selected row. 

gridControlEdit.DataBindings.Clear();
BindingSource bindingSource = gridControlTable.DataSource as BindingSource;
gridControlEdit.DataBindings.Add("DataSource", bindingSource, "aktiv", true, DataSourceUpdateMode.Never);

I am not sure why but bindingSource gets null even if my DataSource of the gridControlTable was set.

The datatype DataSource is not the same type as BindingSource, so your "as" operator is returning null.
