datagridview column header checkbox

Question

hi

    Can I show checkboxes to the column headers in datagridview for each column in my dgv

I Used http://www.codeproject.com/KB/grid/DataGridView_winforms.aspx for help but it replaces the header cells one by one .

Can I use any property of dgv which shows checkboxes for all column headers

Thanks

Answer 1

You cannot use checkboxes in the column headers of your datagridview only text it is not a kind of checked list box which is turned around.

In row/column cells you can use checkboxes in a same way as a checked listbox.

Hi bahushekh,

Thanks for your post!

Please kindly check the following sample code for reference.

Public Class DGVcolumnheader
  Inherits Form
  Public Sub New()
    InitializeComponent()
  End Sub
  Private col As DataGridViewCheckBoxColumn
  Private chkBox As CheckBox
  Private Sub DGVcolumnheader_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    col = New DataGridViewCheckBoxColumn()
    col.Name = "Checkbox"
    col.HeaderCell.Style.Alignment = DataGridViewContentAlignment.MiddleCenter
    Me.DataGridView1.Columns.Add(col)   
    chkBox = New CheckBox()
    Dim rect As Rectangle = Me.DataGridView1.GetCellDisplayRectangle(0, -1, True)
    chkBox.Size = New Size(18, 18)
    chkBox.Location = rect.Location
    AddHandler chkBox.CheckedChanged, AddressOf chkBox_CheckedChanged
    Me.DataGridView1.Controls.Add(chkBox)
  End Sub
  Private Sub chkBox_CheckedChanged(ByVal sender As Object, ByVal e As EventArgs)
    For i As Integer = 0 To Me.DataGridView1.RowCount - 1
      Me.DataGridView1(0, i).Value = Me.chkBox.Checked
    Next
    Me.DataGridView1.EndEdit()
  End Sub
End Class

Best Regards,
