How to refer to ComboBox located in DataGridView?

Question

WPF

I have a DataGridView with one column of type ComboBox.
I have two lines, how can I change the text in the ComboBox in their ComboBox?

Answer 1

I didn’t understand anything, but just in case, advice, when the date is bound, an event is triggered, you process the cells in it and find the necessary controls and do everything you need.
By the way, why not make your own cage?

Answer 2

It was solved like this:
DataGridViewComboBoxCell cell = (DataGridViewComboBoxCell)Tips_memory_table.Rows[0].Cells[0];
cell.Items.Add("Select");
cell.Value = "Select";
