IntroductionEdit

A grid has rows and columns. They have width and height. You can fill a grid with text, numbers or even a picture.

Example 1Edit

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 ToolboxEdit

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 valuesEdit

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.
