C# datagridview 奇数列隔列变色！！

如题，我们都知道奇数行，隔列变色的句子是
dataGridView1.AlternatingRowsDefaultCellStyle.BackColor = Color.LightSteelBlue;
但是奇数列的设置则呢吗没有呢！！请高手指路！多谢

Answer 1

DataGridViewCellStyle style = new DataGridViewCellStyle(); //自定义一种单元格样式.
style.BackColor = Color.LightCyan; //其实就是换种颜色.
dataGridView1.RowHeadersVisible = false; //觉得显示在行头的那个方块不好看,去掉~
dataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect; //单击某个单元格,选中其所在的行,这样看数据蛮方便.
dataGridView1.ColumnHeadersHeightSizeMode = DataGridViewColumnHeadersHeightSizeMode.DisableResizing; //用户不能调整列标题栏的大小.
dataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCells; //列宽度样式,最长的数据能全部显示,这样就不会出现"....."了.
dataGridView1.AlternatingRowsDefaultCellStyle = style; //奇数行的样式设置为先前定义的样式,让相邻行有颜色反差.

Answer 2

cellformatting的时候,根据e.rowindex来隔行配色.
private void dataGridViewCustomer_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
DataGridView dgv = (sender as DataGridView);

if (e.RowIndex >= 0)
{
if (e.ColumnIndex == 3)
{

}
}
}

Answer 3

protected void dataGridView1_RowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow) {
for (int i = 0; i <= dataGridView1.Columns.Count - 1; i++) {
if (i % 2 == 0) {
e.Row.Cells(i).BackColor = Drawing.Color.LightSteelBlue;
}
}
}
}
这个是通过逐个改变奇数列单元格的颜色来实现.

没必要这么啰嗦吧。gridview里可以设置alternate模板，那个模板里可以调整背景色什么地，用不着编码。<alternatetemplate>...
