it is a bug!!!
since you delete all rows then insert new ones
you can call GridCreate(...) to repaint
i'll fix the bug as soon as possible
thanks for the bug report

a tip
if you go advanced
you can use the "#" button
to have the b4a code formatted

No problem, glad I can be of help.
I also had the same problem with the .Clear method.

added SetPropTextColor ( Row , Color )
to set to text color of specific lines

Improvement

Hi Steffano,

Really good grid library, excellent stuff. Could I make a suggestion for a slight improvement, i don't know if this is possibly. The grid has a tendancy to want to scroll horizontal when attempting to scroll vertical. To achieve a vertical scroll it seems the user has to be very precise with vertical on screen touch. To improve this somewhat, could some code be introduced to analyze the the horizontal deviation on touch start and touch end and say if it's less than x number of pixels, assume the user wanted to vertically scroll?

Again, thanks for your efforts with this library, it's much appreciated.

your suggestion deserves a try

AppendRow

Hallo I still have a question to the following syntax:

Dim Tr As TextReader
Dim kZeile As String
Dim aSpalten(col) As String col is a known index

Tr.Initialize(File.OpenInput(File.DirAssets, "demo.txt"))
kZeile = Tr.ReadLine
Do While kZeile <> Null
Dim fZeile() As String
If kZeile.Length > 0 Then
fZeile=Regex.Split(";", kZeile)
For i = 0 To col - 1
aSpalten(i) = fZeile(i)
Next
' Tabelle.AppendRow(Array As String(aSpalten)) line doesn´t work
Tabelle.AppendRow(Array As String(fZeile(0), fZeile(1), fZeile(2)....) this line work
End If
kZeile = Tr.ReadLine
Loop
Tr.Close

with Tabelle.AppendRow(Array As String(aSpalten)) the grid is empty
with Tabelle.AppendRow(Array As String(fZeile(0), fZeile(1),..etc. it´s ok

so what is wrong ?

kind regards Volker
