datagridview中的日历列c＃ [英] calendar column c# in datagridview

问题描述

基本上，我想在编辑Datagridview中的某些列时显示日历。

Basically I want to show a calendar when I edit some columns in my Datagridview.

按照如何：Windows窗体DataGridView单元中的主机控件来自MSDN，我可以在构建时添加所需的列。

Following How to: Host Controls in Windows Forms DataGridView Cells from MSDN I can add wanted kind of column at building.

但就我而言，我必须使用Excel阅读器提供的数据源，其标题必须与日期类型列相关。

But in my case, I have to use a datasource provided by an Excel reader which give headings have to be connected to date type columns.

private DataGridView AddCalendars(DataGridView dtgv)
{
  dtgv.DataSource = controller.getEmptyDataTable();     // DataTable provided by excel reader
  var l = dtgv.Columns.Count;
  string[] dateColumns = {"date_received", "date_of_birth"};
  for (var i = 0; i < l; ++i)
  {
    if ( dateColumns.Any( dtgv.Columns[i].HeaderText.Contains )
    {
      dtgv.Columns[i] = new CalendarColumn();      // this line does not work cause by readonly
    }
  }
  return dtgv;
}

如何将日历列控件应用于选定的列？

How can I apply Calendar Column control to selected columns ?

或者，如何我通过以不同的方式构建Datagridview获得相同的结果吗？

Or, how can I obtain same result by building Datagridview different way ?

}

private void AddCalendars(DataGridView dtgv)
{
  dateColumnsIndexes = new List<int>();
  dtgv.DataSource = controller.getEmptyDataTable();     // DataTable provided by excel reader
  var l = dtgv.Columns.Count;
  string[] dateColumns = {"date_received", "date_of_birth"};
  for (var i = 0; i < l; ++i)
  {
    if ( dateColumns.Any( dtgv.Columns[i].HeaderText.Contains )
    {
