在form里datagridview本身里面没有listbox,用代码怎么才能把listbox加到datagridview的columns中??

Answer 1

要实现什么功能啊，没有listbox为什么不用combobox?

Answer 2

2 datagridview_Click 
  中判断是否该显示Listbox 
是： 
if (dataGridView1.CurrentCell.ColumnIndex==0） 
{   Rectangle rect = dataGridView1.GetCellDisplayRectangle(dataGridView1.CurrentCell.ColumnIndex, dataGridView1.CurrentCell.RowIndex, false); 
Listbox.Left = rect.Left; 
Listbox.Top = rect.Top; 
Listbox.Width = rect.Width; 
Listbox.Height = rect.Height; 
Listbox.Visible = true; 
}

Answer 3

if (dataGridView1.CurrentCell.ColumnIndex==0）  
{    Rectangle rect = dataGridView1.GetCellDisplayRectangle
 这是什么意思了...一运行就报这个错误

Answer 4

  Rectangle rect = dataGridView1.GetCellDisplayRectangle(dataGridView1.CurrentCell.ColumnIndex, dataGridView1.CurrentCell.RowIndex, false);  
是一句话！

自已创建一个 DataGridViewColumn 和相应的DataGridViewListBoxCell
较麻烦．　listbox的没做过，　有一个用DateTimePicker的. 
public class CalendarColumn : DataGridViewColumn
    {
        public CalendarColumn()
            : base(new CalendarCell())
        {
        }
        public override DataGridViewCell CellTemplate

            get
            {
                return base.CellTemplate;
            }
            set

                if (value != null && !value.GetType().IsAssignableFrom(typeof(CalendarCell)))
                {
                    throw new InvalidCastException("Must   be   a   CalendarCell ");
                }

是一句话.我在FORM里画好了..就想在Columns里插入一个listbox,,可没有.
刚才你写的试过了..没有效果
谢谢

Answer 7

我添加的是combobox代码Form_Load中LoadcomboBoxPointType();
 cmbPointType.Visible = false;
 cmbPointType.SelectedIndexChanged+=new EventHandler(cmbPointType_SelectedIndexChanged);
this.dgvGCPs.Controls.Add(cmbPointType);public void LoadcomboBoxPointType()
{
   //透明色初始化设置
   cmbPointType.DrawMode = DrawMode.OwnerDrawFixed;
   cmbPointType.DropDownStyle = ComboBoxStyle.DropDownList;
    cmbPointType.DrawItem += new DrawItemEventHandler(cmbTransparence_DrawItem);
    mbPointType.ItemHeight = 18;
    cmbPointType.BeginUpdate();
    cmbPointType.Items.Clear();
     //循环遍历添加每一项
    cmbPointType.Items.Add("控制点");
    cmbPointType.Items.Add("检查点");
    cmbPointType.EndUpdate();
 }private void dataGridView_Click(object sender, EventArgs e)
{
if (dataGridView1.CurrentCell.ColumnIndex == (int)GeoRectificationTable.TableAttributeIndex.pointType && dataGridView1.CurrentCell.RowIndex < (myGeoRectificationTable.BasePointNumber > myGeoRectificationTable.WarpPointNumber ? myGeoRectificationTable.BasePointNumber : myGeoRectificationTable.WarpPointNumber))
                {
                    Rectangle rect = dataGridView1.GetCellDisplayRectangle(dataGridView1.CurrentCell.ColumnIndex, dataGridView1.CurrentCell.RowIndex, false);
                    string sexValue = dataGridView1.CurrentCell.Value.ToString();
                    cmbPointType.Left = rect.Left;
                    cmbPointType.Top = rect.Top;
                    cmbPointType.Width = rect.Width;
                    cmbPointType.Height = rect.Height;
                    cmbPointType.Visible = true;
                }
                else
                {
                    cmbPointType.Visible = false;
                }
}private void cmbTransparence_DrawItem(object sender, DrawItemEventArgs e)
        {
            ComboBox cmbTransparence = (ComboBox)(sender);
            if (e.Index < 0) return;            e.DrawBackground();            //得到绘制的矩形框
            Rectangle rect = new Rectangle(4, e.Bounds.Top + 2, e.Bounds.Height + 10, e.Bounds.Height - 4);            string colorName = cmbTransparence.Items[e.Index].ToString();
            Font pFont = new Font(FontFamily.GenericSansSerif, 10, FontStyle.Regular);            //在指定的矩形内绘制文本
            e.Graphics.DrawString(colorName, pFont, Brushes.Black, new Rectangle(e.Bounds.X, e.Bounds.Y, e.Bounds.Width, e.Bounds.Height));
            //在指定的边界范围内绘制聚集框
            e.DrawFocusRectangle();
        }
