If you like my grid.
You can support the development.

Check columns ( how-to )

cc(2).Initialize2 ...
cc(2).RowIconTop  = 6dip 
cc(2).RowIconLeft = 6dip 
cc(2).setTypeCheck

the column will display a green tick if the value of the column is "1"
nothing otherwise

RowIconTop and RowIconLeft can be used to adjust
the position of the tick in the cell

@aviario

to setup a custom image for check columns
you can use an image column with a single value
cc(0).Initialize ...
cc(0).RowIconPut("1",bmp)
cc(0).SetTypeImage
anyway i'm adding the property for the image
and also the value

what do you mean for printing?

If you know of any library to print on printer

In the grid when the text of the column is larger than the width puts in two columns, there is the possibility to resize the height of that column automatically?

 

[stefanobusetto]

No. I've developed an application that needs to print and i've decided to create pdfs. I've a good lib for that.

There is no autosize planned sorry.

 

[aviario]

Hi,
If i use Cgrid.ScrollTop, grid goes to first line, but can i select by code the first line?

Thanks

 

[stefanobusetto]

Hi,
you can use SelectRow. I've exposed the method and posted version 2.05.
I've also added
- CheckIcon to set the icon
- CheckValue to set the "check" value
for the check columns

 

[aviario]

Hello,

Can i set a diferent Row Height in grid?.

Thanks

 

[stefanobusetto]

The RowHeight property allows to the the height of the rows.
I think you want to set instead the height of a given row.
Isn't it?

 

[aviario]

Yes. Thanks

 

[jrat]

Whether it is possible to make FastScroll for big grids?
Like ListView1.FastScrollEnabled

 

[stefanobusetto]

@jrat
great idea!
i'll add in the next release

 

[stefanobusetto]

@magi6162

Grid.Initialize("Grid")

Dim c(4) As xnGridCol
c(0).Initialize ( "Cod." , "cod" , 15%x )
c(1).Initialize ( "Des." , "des" , 60%x )
...

For i = 0 To c.Length - 1
    Grid.AppendCol ( c(i) )
Next

...

Dim ss As String
ss = "select cod , des , ... from ... " 

Grid.DeleteRows

Dim cc As Cursor
cc = Main.db.execquery ( ss & " limit 100 ")
Grid.CursorAppend ( cc )

 

[stefanobusetto]

Please try
...GridWidth=1
instead of
...GridWidth=1dip

 

[stefanobusetto]

i use the grid with several devices
smartphones an tablets and
i've no problems with the grid lines
it could be the emulator (android version, display size, resolution, ...)
if you can supply some details on the vm
may be i can arrange some testing

as for the sorting i'm sorry
i thought i've already answered
i'm doing some test
to decide if add it or not

 

[stefanobusetto]

@aviario
Now you can set the height of each row
with PropSetHeight ( Row , Height )

 

[stefanobusetto]

@magi6162
i've added fast scroll
set FastScroll = True to enable
it is disabled by default

 

[stefanobusetto]

Do you mean the grid or the grid lines?
What do you mean the grid is link to cursor?

 

[stefanobusetto]

@magi6162
your code looks ok.
here attached the test program i use to debug the grid.
can you try if it works and if you can see the grid please?
the app creates a local database and loads the grid with
the CursorAppend method.
ciao

 

[stefanobusetto]

don't worry pal
we'll get the hang of it
may you send a sample db
and the layout please?

 

[aviario]
