Hi

No doubt that the code is correct but how do you set a cell back color, because I am having trouble doing this.

With the same code that you wrote:

B4X:
If aCol = 1 Then
  If aRow = 1 Then
  aProps.BackGroundColor = Colors.Green
  End if
End if
Maybe you haven't changed the word "gg" with the name of your xnGrid

Hi this is the code I am using 'TimeGrid' is the name of my grid

B4X:
Dim props As xnGridCellProps

        TimeGrid_CellProps(2 , 1, "0", props)

    End If
End Sub

Sub TimeGrid_CellProps (aCol As Int , aRow As Int , aValue As String , aProps As xnGridCellProps )
    If aCol = 2 Then
           If aRow = 1 Then
             aProps.BackGroundColor = Colors.Red
           End If
    End If
End Sub

Try this please.

B4X:
Sub <....>_CellProps ( aCol As Int , aRow As Int , aValue As String , aProps As xnGridCellProps )
If aCol = 1 Then
   aProps.BackGroundColor = Colors.Gray
End If

If aCol = 1 Then
   If aRow = 1 Then
      aProps.BackGroundColor = Colors.Green
   End If
End If
End Sub
The prevoius code sets the background color of the column 1 to Gray
and the background color of the column 1 of the row 2 to green

Hi Stefano

I got it to work (sort of) as I did not expect the <...>_CellProps to trigger when I clicked on the grid, is that correct?.

I suppose I was looking for something like nameofgrid.cell(row,col).backcolor = colors.red, does that seem like it is something possible to do?

Regards

David

Hi again,

Is it possible to make a row visible but "disabled", so it does not respond to clicks or longclicks and looks slightly different?

There is no such built in feature.
But if you can create a list of disabled rows indexes and use
the On_CellProps event to custom color the row/cell.
And of course use the same list in the On_Click events
to take no action.

Yes several times.
Should i have some requests i'll do it.
Sorting can be easely achieved using the events
already present in the grid.

Thank you for the great grid. I can't seem to determine how to "hide" a row. Is this possible? If not can you make it possible? ;)
