I'll check the grid create issue
PropSetHeight must be called after
creating the columns.

aviario · Jun 25, 2013

I get the same error when I have the grid loaded and change the height of a row

thanks

@magi6162
without db i could suggest to try this
minimal code and upper case field names

B4X:

grdS.Initialize("GS")
    Activity.LoadLayout("Storico")
    Activity.AddMenuItem("Barra di scorrimento","BarraOnOff")

    cursorS = Main.gecoDB.ExecQuery("select STORICO.IDSTORICO as IDSTORICO " & _
                                     "from STORICO " & _
                                     "Order By STORICO.RAGSOC ASC")

    bmpSortUp.Initialize ( File.DirAssets, "Sort-Ascending.ico" )
    bmpSortDown.Initialize ( File.DirAssets, "Sort-Descending.ico" )
    
    cc(0).Initialize2("IDSTORICO","IDSTORICO",0dip,Gravity.CENTER_HORIZONTAL + Gravity.CENTER_VERTICAL)
    grdS.ColAppend(cc(0))

    grdS.CursorAppend(cursorS)
    
    pnlGrd.AddView ( grdS , 0dip , 0dip , 100%x, 100%y)
    grdS.GridCreate

@aviario
I've tested the GridCreate2 method with both true and false param.
I've also tested the PropSetHeight calling it before and after
GridCreate2 but i've not been able to get the errors.
I can suggest to:
1) initialize the grid
2) initialize and add the grid columns
3) fill the grid
4) create the grid
You can then:
a) test if a row exists
b) set the height of the row
I'll be glad to have a look at your code if you post it or send by email.

This is an example

thanks

Great problem!

I've been able to reproduce it with the code you've posted.
I've also been able to create your grid pasting your code in
my xnGridTest example app.

I'll work on it.
Really strange indeed!

@aviario
replace

B4X:

cgrid.GridCreate2 (True)

with

B4X:

DoEvents
cgrid.GridCreate2 (True)

Thanks, now works ok

stefanobusetto · Jun 28, 2013

@magi6162
the DoEvents solution should work also for you

stefanobusetto · Jun 28, 2013

we'll work on grid lines too!
may you send a minimal projects
i can test

stefanobusetto · Jun 28, 2013

i know the problem
i'd like a full b4a project
to test on multiple devices and emulators

stefanobusetto · Jun 28, 2013

see image

stefanobusetto · Jun 28, 2013

touch the scrollbar at the right side of the grid
keep the finger on the display and move it
up or down

stefanobusetto · Jun 29, 2013

What do you mean? Some columns to the left always visibile when scrolling horizontally?

Try PixelFix = true
for the grid problem

stefanobusetto · Jul 2, 2013

i'll have a look
but i'm quite sure the current
implementation of the grid is quite
incompatible with the desired feature

stefanobusetto · Jul 9, 2013

Yes it is possible.
Can't tell if i'm adding the feature
or when. I'm working on multiline
rows now.

aviario · Jul 10, 2013

Hi, When I put two grid in a tabhost me sample the first but the second if I put cgrid1.GridCreate2 (False) shows me the head but not the data and if I put cgrid1GridCreate2 (True) shows nothing

thanks

stefanobusetto · Jul 10, 2013

I'm on holidays till sunday.
Then i'll have a look at the code.

aviario · Jul 12, 2013

Thanks, I checked it with version 2.5 works ok

Tag property on a row?

Do you think it's possible to get a "Tag" property on the rows just to store a data ID or something?
