Wouldn't a CustomListView work better here?

This came from one of the web view tutorials

B4X:

Sub WebView1_OverrideUrl (Url As String) As Boolean
    'parse the row and column numbers from the URL
    Dim values() As String
    values = Regex.Split("[.]", Url.SubString(7))
    Dim col, row As Int
    col = values(0)
    row = values(1)
    ToastMessageShow("User pressed on column: " & col & " and row: " & row, False)
    Return True 'Don't try to navigate to this URL
End Sub

Thank You..

, But I want to get the content of Id and Items. The above code will will give only index of particular Row and Column..Is it possible to get the content of selected row and column

You can change the url structure to include the content together with the index.

A simpler approach will be to call ExecuteMemoryTable to get the complete data and then you can take the column and row from the event and find the content from the table.
