我DataGridView只修改它的日期，但说到Printing preview它也给了我时间。我该如何删除它？而且我希望它自动调整每一列
样本输出：
这是我的代码
打印文件：

//For the first page to print set the cell width and header height
if (bFirstPage)
{

GridCol.InheritedStyle.Font, iTmpWidth).Height) + 2;
// Save width and height of headres
arrColumnLefts.Add(iLeftMargin);

开始打印：
try
{
strFormat = new StringFormat();
strFormat.Alignment = StringAlignment.Near;
strFormat.LineAlignment = StringAlignment.Center;
strFormat.Trimming = StringTrimming.EllipsisCharacter;
arrColumnLefts.Clear();
arrColumnWidths.Clear();
iCellHeight = 0;
iRow = 0;
bFirstPage = true;
bNewPage = true;
// Calculating Total Widths
iTotalWidth = 0;
foreach (DataGridViewColumn dgvGridCol in dataGridView1.Columns)
{
iTotalWidth += dgvGridCol.Width;
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
按钮打印：
private void button4_Click(object sender, EventArgs e)
{
//Open the print dialog
PrintDialog printDialog = new PrintDialog();
printDialog.Document = printDocument1;
printDialog.UseEXDialog = true;
//Get the document
if (DialogResult.OK == printDialog.ShowDialog())
{
printDocument1.DocumentName = "Test Page Print";
printDocument1.Print();
}
//Open the print preview dialog
PrintPreviewDialog objPPdialog = new PrintPreviewDialog();
objPPdialog.Document = printDocument1;
objPPdialog.ShowDialog();
}
