I have two-dimensional strings array...

SArr(32, 11) As String

and would like to create from that xnGrid with 11 columns and 32 rows.
There is no problem with 11 columns creation but how in a cycle to add all those rows?

For r = 1 To rows
gg.RowAppend(SArr(r)) 'doesn't work
Next

Hello,

What if I need to change the row color depending on the value of the column 3 (in example)?

Many thanks!

[ EDIT ]

ok! I found the method DG_RowProps. But, as I said, I need the BackgroundColor property.

Do you know when will it arrive?

Thanks again!

Hi Stefano,
it is possible, in the future, add a command to move the lines?

example:
gg.RowMove (CurrenteRow, NewRow)

Thanks

@David Cochrane

RowAppend requires an array() with one value for each
column of the grid

@BluSky76

I dont think so
Sorry

I belive the grid must only display data
So you should, in my opinion, exchange the
underlying data and then refresh the grid

Hello, I was wondering if it possible to get a a event on _CellRelease(Row As Int, Col As Int) So you can mark when you release the finger from the screen. Do you think that is possible?

Hi Stefano,

you can delete only the selected rows from the grid?

Thanks

Here it is the code:

B4X:

Private grid As xnGrid
Sub grid_CellClick ( Col As Int, Row As Int )
grid.RowDelete(Row)
End Sub

Thanks for the reply.

I do not want to delete a single line but with a command to delete all selected rows. If the grid contains 100 rows and 20 are selected I want to delete a command only the twenty selected.

example
grid.RowDeleteSelect

Thank you

Hi!
Using xnGrid,
Is there the possibility to select a single cell instead of the full row?

Thanks!

Use the "CellProps" event

B4X:

Sub gg_CellProps ( aCol As Int , aRow As Int , aValue As String , aProps As xnGridCellProps )
If aCol = 1 Then
   aProps.TextColor = Colors.Red
   aProps.BackGroundColor = Colors.Gray
End If

If aCol = 1 Then
   If aRow = 1 Then
      aProps.BackGroundColor = Colors.Green
   End If
End If
End Sub

I am new to this library. It looks very promising.
I created a test program and the CellProps event is giving a java error.
"java.lang.IllegalStateException: This method must only be called as part of a callback while a frame is in progress."

My phone is a new Note 8 - Android 7.1.1

What I am trying to accomplish is as follows,
When I long click a row or based on a db record, set that row to a color.
The original SetPropColor would have been perfect for my needs.

-----------------
I changed the program from GridCreate2(False) to GridCreate and the java error went away.
Now, I can get it to do what I want.
