Android Question Get checked rows in B4Xtable

[Mostez]

based on Erel's example, i added checkbox to B4Xtable column and name it 'Select' now i want to iterate thru table rows to get checked-only rows. how to do this?

tblPhoneContacts.Clear
CheckColumn = tblPhoneContacts.AddColumn("Select", tblPhoneContacts.COLUMN_TYPE_TEXT)
CheckColumn.Width = 60dip
CheckColumn.Searchable = False
CheckColumn.Sortable = False

For i = 1 To CheckColumn.CellsLayouts.Size - 1 'add custom check box to table
    'Sleep(0)
    Dim pnl As B4XView = CheckColumn.CellsLayouts.Get(i)
    Dim ColCheckBox As CheckBox
    ColCheckBox.Initialize("")
    St.SetButtonTintList(ColCheckBox,Colors.Gray,SysDeclare.COLOR_DARK_NAVY)
    pnl.AddView(ColCheckBox, 5dip, 5dip, CheckColumn.Width - 10dip, tblPhoneContacts.RowHeight - 10dip)
Next

now i want to iterate thru table rows to get checked-only rows

Maybe something like this:

Sub btn_Click
    For i = 0 To B4XTable1.VisibleRowIds.Size - 1
        Dim RowId As Long = B4XTable1.VisibleRowIds.Get(i)
        Dim pnl As B4XView = CheckColumn.CellsLayouts.Get(i + 1) '+1 because first cell is a header
        Dim ColCheckBox As CheckBox    = pnl.GetView(1)
        If RowId > 0 Then
            Dim row As Map = B4XTable1.GetRow(RowId)
            If ColCheckBox.Checked Then
                Log($"Checked rowid ${RowId} "$)    
'                Log($"rowid ${RowId}   ${row.Get("Name")}"$)  'Name is header of another column to display  
            End If
        End If
    Next    
End Sub

thanks, it worked OK, this line is not used

Dim row As Map = B4XTable1.GetRow(RowId)

 

[Mahares]

Dim row As Map = B4XTable1.GetRow(RowId)

Hi @Mostez: If you uncomment the line I have commented in the code, the line will be used. If you have another column named Name for example, it will show you the content of each based on the rowid. You can use another col name if you want.

Another possible approach is to use B4XTableSelections and set the selection mode to MULTIPLE_LINES: https://www.b4x.com/android/forum/t...extended-selection-modes-for-b4xtable.114294/

i tried both methods, Erel's method is much simpler to implement, now I need to iterate thru table to get selected rows, how to do that?
thanks

To iterate thru the table to get selected rows, you need to use: XSelections.SelectedLines.Keys

For Each rowid As Long In XSelections.SelectedLines.Keys
   'your code here. If you have trouble, post your code. Someone may be able to help.

big thanks, it worked without problems, so far

For Each rowid As Long In TableStyle.SelectedLines.Keys
                Dim row As Map = tblPhoneContacts.GetRow(rowid)
                    Cont.CompanyName =     row.Get("CompanyName")
                    Cont.ContactName = row.Get("ContactName")
                   ...

            Next
