如何格式化导出到Excel的DataGridView的背景？

Question

I want to format the background of my header cells in excel, which is populated trhough my Datagridview. I´ve tried it with

ws.Cells[1. 2].Style.Fill.PatternType = ExcelFillStyle.Solid;

ws.Cells[1, 2].Style.Fill.BackgroundColor.SetColor(Color.LightGray);

but i got a error message which says the name ExcelFillStyle.Solid does not exist in the current context. Any ideas?

Thank you

Firstly welcome to the SO community as a new contributor !

Doing some research I would recommend changing the header-color of the GridView using something like this:

_dataGridView.ColumnHeadersDefaultCellStyle.BackColor = Color.Blue;
_dataGridView.EnableHeadersVisualStyles = false;

This was found on SO here: SO - How to change the color of dataGridView header

However If you wanted to tackle this using a more custom approach where you can set specific cells (items) background colors, this can be done using using:

DataGridView1.CurrentCell = DataGridView1.Item("ColumnName", 5)

columnHeadingsRange.Interior.Color = XlRgbColor.rgbSkyBlue;

The use case for this is explained on SO here:

Using these two sources should help you achieve what you need as these both have been answered .
