DatagridView column size

Hello, I want to resize some columns on form load programmatically. Here's my code:

Code:

---

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

    Dim resetBtn = New Button With {.Text = "S", .Width = 20}
    dtp.Name = "dtp"
    dtp.Width = 80

    'TODO: This line of code loads data into the 'MakbuzDataSet.makbuzT' table. You can move, or remove it, as needed.
    Me.MakbuzTTableAdapter.Fill(Me.MakbuzDataSet.makbuzT)

    MakbuzTDataGridView.Dock = DockStyle.Bottom

    Me.SavePending = True

    AddHandler dtp.ValueChanged, AddressOf DateTimePicker1_ValueChanged
    FillByTest08ToolStrip.Items.Add(New ToolStripControlHost(dtp))

    FillByTest08ToolStrip.Items.Add(New ToolStripControlHost(resetBtn))

    Button1.Visible = False
    FillByTest08ToolStrip.Margin = New Padding(150, 150, 150, 150)
    FillByTest08ToolStrip.Dock = DockStyle.Top
    MakbuzTDataGridView.Dock = DockStyle.Fill
    MakbuzTDataGridView.ColumnHeadersHeightSizeMode = DataGridViewColumnHeadersHeightSizeMode.DisableResizing
    MakbuzTDataGridView.ColumnHeadersHeight = 75
    MakbuzTDataGridView.EnableHeadersVisualStyles = True

    AddHandler resetBtn.Click, AddressOf onresetBtnClick

    MakbuzTDataGridView.CurrentCell = MakbuzTDataGridView(0, 0)
    MakbuzTDataGridView.TabIndex = 0

    MakbuzVars = Utils.Load(Of Info)("ayarlar.xml")
    MakbuzTDataGridView.Columns(1).Width = 150

End Sub

I'm using Visual Studio 2012. How can I resize a column?

Code:

---

DataGridView1.Columns(columnIndex).Width = 100

---

seems you've already found how???:

Code:

---

MakbuzTDataGridView.Columns(1).Width = 150

---

Thanks for the reply. Yes, I tried it, it doesn't work.

in the first line of Form1_Load, put Stop.
then run the code, when it stops, step through the code (F11)

are there any unexpected problems?

no, there isn't any problems

But I'm getting a warning:

Uploaded with ImageShack.us

at this line: Me.MakbuzTTableAdapter.Fill(Me.MakbuzDataSet.makbuzT)

just click yes on the dialog.

after:

Code:

---

MakbuzTDataGridView.Columns(1).Width = 150

---

put:

Code:

---

MsgBox(MakbuzTDataGridView.Columns(1).Width)

---

it shows 150 :(

the DataGridViewColumn has 2 properties that would affect this... Resizable + AutoSizeMode

I tried:

Code:

---

MakbuzTDataGridView.Columns(1).Resizable = False
MakbuzTDataGridView.Columns(1).AutoSizeMode = DataGridViewAutoSizeColumnMode.None

MakbuzTDataGridView.Columns(1).Width = 150

---

Same thing

I can't recreate your problem, so there's nothing more I can think of to suggest...

ok, thanks anyway

are you sure that the column you're expecting to be at index 1 is in fact index 1?
if you have any hidden columns or reordered columns, you could be looking at the wrong column

:) just a stupid mistake. thanks a lot.

last guess - I think you'll probably find you need to adjust the column width after setting your datasource
