Introduction
[edit | edit source]A grid has rows and columns. They have width and height. You can fill a grid with text, numbers or even a picture.
Example 1
[edit | edit source]You need a new form to get the program going. On this form you place a gridview , which you can find in your toolbox. There should be a picture x.png in your directory. Otherwise it wont be shown. There wont be an error message, when it is not found.
STATIC PUBLIC SUB Main()
hForm AS Fmain
hForm = NEW Fmain
hForm.show
END
PUBLIC SUB _new()
GridView1.Columns.Count = 4
GridView1.Rows.Count = 3
GridView1.Columns.Width = 52
GridView1.Rows[1].Height = 52
GridView1[0,0].Text = "0,0"
GridView1[0,0].Alignment = 4
GridView1[1,1].Text = "1,1"
GridView1[0,1].Text = "0,1"
GridView1[1,0].Picture = Picture["x.png"]
END
Create a Grid without the Toolbox
[edit | edit source]The grid ist creatable. How it is done shows the little example.
g AS Gridview
PUBLIC SUB _New()
g = NEW Gridview(ME) AS "Gridview1"
g.show
g.Columns.Count = 4
g.Rows.Count = 3
g.Columns.Width = 52
g.Rows[1].Height = 52
END
You just need a empty form to get the program going.

Fill the grid with some values
[edit | edit source]You have a list of values and you want to have them in a grid. The example shows you a solution. Still not very nice and with some German words in it.
You need the following controls:
- 1 Textarea
- 1 Gridview
- 2 Commandbuttons
The code
PUBLIC SUB Button1_Click()
textarea1.Text = "114"
textarea1.Text = textarea1.Text & Chr(10) & "135"
textarea1.Text = textarea1.Text & Chr(10) & "104"
textarea1.Text = textarea1.Text & Chr(10) & "118"
textarea1.Text = textarea1.Text & Chr(10) & "125"
textarea1.Text = textarea1.Text & Chr(10) & "121"
textarea1.Text = textarea1.Text & Chr(10) & "122"
textarea1.Text = textarea1.Text & Chr(10) & "96"
textarea1.Text = textarea1.Text & Chr(10) & "118"
textarea1.Text = textarea1.Text & Chr(10) & "120"
textarea1.Text = textarea1.Text & Chr(10) & "112"
textarea1.Text = textarea1.Text & Chr(10) & "127"
textarea1.Text = textarea1.Text & Chr(10) & "122"
textarea1.Text = textarea1.Text & Chr(10) & "128"
textarea1.Text = textarea1.Text & Chr(10) & "120"
END
PUBLIC SUB _new()
GridView1.Columns.Count = 2
GridView1.Rows.Count = 15
GridView1.Columns.Width = 72
END
PUBLIC SUB Button2_Click()
DIM text AS String
DIM Liste AS String[]
DIM Einzelwert AS String
DIM x AS Integer
x = 0
text = textarea1.Text
Liste = Split(text,Chr(10))
FOR EACH Einzelwert IN Liste
GridView1[x,1].Text = Einzelwert
GridView1[x,0].Text = x
x = x + 1
NEXT
PRINT liste.Length
END
When you push button1, then the textarea is filled with values. When you push button2, they will be placed in the grid.
You can improve this program if you want. It looks a little newbee like.
