如何更改datagridView标头颜色

Question

Now the datagridView Header Background color is showing in Gray. I want to change to differenct color.

I Changed the background color in ColumnHeaderDefaultCellStyle , but nothing changed.

How to do this.

Answer 1

Set the property EnableHeadersVisualStyles to False , then change the ColumnHeaderDefaultCellStyle background color to the color that you desire. You will be able to see the changes in the designer itself.

Answer 2

Also, if you are trying to set the color (back or fore)color or other properties of the individual column's header (not all at once) use

datagridview.Columns(e.ColumnIndex).HeaderCell.Style.BackColor = color.cyan
datagridview.Columns(e.ColumnIndex).HeaderCell.Style.(ForeColor or Font or Alignment etc) = whatever

where e.ColumnIndex was taken from the EventArgs of your Event, but you can alter accordingly.

Answer 3

In datagridView you can change the Header color by using DataGridViewCellStyle , see the following code

       ' Set the selection background color for all the cells.
    dataGridView1.DefaultCellStyle.SelectionBackColor = Color.White
    dataGridView1.DefaultCellStyle.SelectionForeColor = Color.Black

    ' Set RowHeadersDefaultCellStyle.SelectionBackColor so that its default
    ' value won't override DataGridView.DefaultCellStyle.SelectionBackColor.
    dataGridView1.RowHeadersDefaultCellStyle.SelectionBackColor = Color.Empty

    ' Set the background color for all rows and for alternating rows. 
    ' The value for alternating rows overrides the value for all rows. 
    dataGridView1.RowsDefaultCellStyle.BackColor = Color.LightGray
    dataGridView1.AlternatingRowsDefaultCellStyle.BackColor = Color.DarkGray

    ' Set the row and column header styles.
    dataGridView1.ColumnHeadersDefaultCellStyle.ForeColor = Color.White
    dataGridView1.ColumnHeadersDefaultCellStyle.BackColor = Color.Black
    dataGridView1.RowHeadersDefaultCellStyle.BackColor = Color.Black

EDIT:

Using the DataGridViewCellStyle, your header color will changes but a seperator for columns in the header section will not appear. So, heres a overrided event of OnPaint Event Handler have a look at this
