我有服务器上的数据以smalldatetime
的形式出现,但是当我将这些数据返回给我的应用程序时,它以string
的形式返回给我。发生这种情况的原因有多种,不适用于此问题。
我想做的是,当此数据填充到DataGridView中时,我需要将其格式化为datetime
,且没有日期,时间格式为“ mm/dd/yyyy
”。我已经尝试了以下操作,但是数据仍然采用“ mm/dd/yyyy hh:mm
”格式:
this.DataGridView.Columns[7].DefaultCellStyle.Format = "d";
如何格式化此列数据?
最佳答案
使用Column.DefaultCellStyle.Format属性或将其设置为in designer
要么
dataGridView1.Columns[0].DefaultCellStyle.Format = "MM'/'dd'/'yyyy";
要么
您可以设置所需的格式:
dataGridViewCellStyle.Format = "MM/dd/yyyy";
this.date.DefaultCellStyle = dataGridViewCellStyle;
// date being a System.Windows.Forms.DataGridViewTextBoxColumn
你可以这样...
private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
// If the column is the Artist column, check the
// value.
if (this.dataGridView1.Columns[e.ColumnIndex].Name == "Artist")
{
if (e.Value != null)
{
// Check for the string "pink" in the cell.
string stringValue = (string)e.Value;
stringValue = stringValue.ToLower();
if ((stringValue.IndexOf("pink") > -1))
{
e.CellStyle.BackColor = Color.Pink;
}
}
}
else if (this.dataGridView1.Columns[e.ColumnIndex].Name == "Release Date")
{
ShortFormDateFormat(e);
}
}
//Even though the date internaly stores the year as YYYY, using formatting, the
//UI can have the format in YY.
private static void ShortFormDateFormat(DataGridViewCellFormattingEventArgs formatting)
{
if (formatting.Value != null)
{
try
{
System.Text.StringBuilder dateString = new System.Text.StringBuilder();
DateTime theDate = DateTime.Parse(formatting.Value.ToString());
dateString.Append(theDate.Month);
dateString.Append("/");
dateString.Append(theDate.Day);
dateString.Append("/");
dateString.Append(theDate.Year.ToString().Substring(2));
formatting.Value = dateString.ToString();
formatting.FormattingApplied = true;
}
catch (FormatException)
{
// Set to false in case there are other handlers interested trying to
// format this DataGridViewCellFormattingEventArgs instance.
formatting.FormattingApplied = false;
}
}
}
