如何从代码后面编辑 Gridview 列字体？

Question

I want to edit certain column font size

/*Line 47*/  GridView1.HeaderRow.Cells[0].Text = "";
/*Line 48*/  GridView1.Columns[0].ControlStyle.Font.Size= 40; // the bug is here
/*Line 49*/  GridView1.HeaderRow.Cells[1].Text = "Report Name";

Line 48 gives error:

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Answer 1

//First Use Header File

using System.Drawing;

// than

 BridView1.ControlStyle.Font.Size = 9;

Answer 2

Columns property references the columns in your grid-view setup, if you wanted to just access a targeted column in a specific row then:

GridView1.Rows[0].Cells[0].ControlStyle.Font.Size = 40;

Would be used, otherwise you may as well just set the ControlStyle in your column when you construct it (either in code or designer).
