Get the current DataRow in DataTable

[Soif2Sang]

Hi, i'm looking for a way to get the current DataRow when I click on it.
Here is what I tried :

class Main:
    def __init__(self,page:ft.Page):
        self.page = page
        self.page.window_height = 600
        self.page.window_width = 800
        self.page.horizontal_alignment = "center"
        self.rows = {}
        self.database = \
            ft.DataTable(
                data_row_color={ft.MaterialState.HOVERED: ft.colors.GREEN},
                sort_column_index=0,
                sort_ascending=True,
                columns=[
                    ft.DataColumn(ft.Text("ID")),
                ]
            )
        self.page.add(
            self.database
        )
        def updateTable(e):
            for i in range(4):
                print(i)
                self.rows[str(i)] = ft.DataRow \
                    (
                        on_select_changed=lambda e: print(f"row select : {i}"),
                        cells=[
                            ft.DataCell(ft.Text(str(i)))
                        ],
                    )
            self.database.rows = self.rows.values()
            page.update()
            print(self.rows)

        self.page.add(
            ft.FilledButton("Refresh DataTable", icon=ft.icons.REFRESH, on_click=updateTable),
        )

ft.app(target=Main)

But no matter which row I click on, here is the result :

row select : 3
row select : 3
row select : 3
row select : 3

Use the param e and you can access the row using e.control

on_select_changed=lambda e:  e.control # <-- do something with `e.control`

You can store data on the row or check the index of that row from the table

Thank you very much !

This method will be work if I append the rows in other UserControl? in a separate file?

[OtherwisePitt92]

how to check index of the row?

[ndonkoHenri]

I think you can do something like e.control.parent.rows.index(e.control)

for me , It took time to understand what data should I retrieve from e.control.
for those who are in the same situation

on_select_changed=lambda e: print(
                        f"row select : {e.control.cells[0].content.value}"
                    ),
