Question

I don't have codes to show because I created it from scratch and I don't know how to start it. Instead, I will show some image of my desired UI.

I have 2 Columns ("Types of Downtime","Description") in my DataGrid.

I added in Item Collection with ("Manpower", "Machine").

Here's my expected result.

If I click "Machine" the second column will populate "Motor" and "Computer"

else If I click "Manpower" it will populate "Dela Cruz" and "Dela Torre".

Hope you can help me on this. Thanks!

Maybe you can use a construction similar to the one in this example that captures the keyboard input and places a "fake" ComboBox:
