In SfComboBox, you can bind the SelectedValue property of the SfComboBox. When SfComboBox is used as a template for the SfDataGrid column, set the SelectedValue in a separate SfComboBox. You can also set the SelectedValue for each SfComboBox in the SfDataGrid in a loaded event. This can be achieved in the following code.
