How to set style in for a column in DataGridView at design time

There's a question about changing cell background color in a DataGridView programatically

But is there any way to set the background color for a particular column using the WinForms Designer?

1. Right click the DataGridView and select Edit Columns

   

2. Select the DefaultCellStyle Property and click on the Style Wizard

   

3. In the CellStyle Builder window, you can set whatever properties you'd like, including BackColor

   

What this will do is set the property inside of the form.designer.cs file during InitializeComponent()

private void InitializeComponent()
{
    /// ...
    this.ShadedColumn.DefaultCellStyle.BackColor = Color.Silver;
    /// ...
}

^{* where this.ShadedColumn is the name of the DataGridViewTextBoxColumn control you added}

Any code in InitializeComponent will execute during the designer view, and technically you can update most styles directly here, but it's advised to use the GUI form builder to make any changes against this file
