[Closed] DataGridView and ComboBoxes

Should be simple… user changes the dropdown box… press the button, it should print the value in the box. But you need to click to deactivate the dropdown list to make it work… Anyone got a trick to make this behave like it should do?

try(destroyDialog ro_Test)catch()

rollout ro_Test "Test" width:800
(
	dotNetControl gv_Test "System.Windows.Forms.DataGridView" width:790 height:300 offset:[-8,0]
	
	button btn_test "Test"
	
	on ro_Test open do
	(
		
		gv_Test.SelectionMode = gv_Test.SelectionMode.FullRowSelect
		gv_Test.AllowUserToAddRows = false
		
		dnNewColumn = dotNetObject "System.Windows.Forms.DataGridViewCheckBoxColumn"
		dnNewColumn.HeaderText = "Export"
		gv_Test.columns.add dnNewColumn
		
		dnNewColumn = dotNetObject "System.Windows.Forms.DataGridViewComboBoxColumn"
		dnNewColumn.HeaderText = "Category"
		dnNewColumn.items.AddRange (#("A","B","C"))
		gv_Test.columns.add dnNewColumn
			
		gv_Test.Rows.Add #(True, "A")
		gv_Test.Rows.Add #(True, "A")
	)
	
	on btn_test pressed do
	(
		messageBox ("row1:" + (gv_Test.rows.item[0].cells.item[1].value) as string)
		messageBox ("row2:" + (gv_Test.rows.item[1].cells.item[1].value) as string)
	)
)
createDialog ro_Test
