2个功能，解决马上结贴
之前做ASP.NET
现开始接触WINFORM ，请问下面两项功能如何实现。


1第一列显示图片，按照数据库状态改变图片状态。
2右击出现菜单，点击后执行我设置的方法。

[解决办法]

C# code

用DataGridView控件  public System.Drawing.Image GetImage(string path)        {            System.IO.FileStream fs = new System.IO.FileStream(path, System.IO.FileMode.Open);            System.Drawing.Image result = System.Drawing.Image.FromStream(fs);            fs.Close();            return result;        }        private void demoGrid_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)        {          //这里写判断条件，根据条件显示不同图片            if (demoGrid.Columns[e.ColumnIndex].Name.Equals("Image"))            {                string path = System.Windows.Forms.Application.StartupPath + @"/1.gif";                e.Value = GetImage(path);            }        }//设置右键菜单     private void dgvList_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)        {            if (e.Button == MouseButtons.Right)            {                if (e.RowIndex >= 0)                {                    if (dgvList.Rows[e.RowIndex].Selected == false)                    {                        dgvList.ClearSelection();                        dgvList.Rows[e.RowIndex].Selected = true;                    }                    if (dgvList.SelectedRows.Count == 1 && e.ColumnIndex != -1)                    {                        dgvList.CurrentCell = dgvList.Rows[e.RowIndex].Cells[e.ColumnIndex];                    }                    dgvList.ContextMenuStrip = contextMenuStrip1;                }                else                {                    dgvList.ContextMenuStrip = null;                    return;                }            }        }//执行方法  private void tsmDelete_Click(object sender, EventArgs e)        {  }

右键菜单可以在 RowsAdded 事件里指定

C# code

private void dataGridView1_RowsAdded(object sender, DataGridViewRowsAddedEventArgs e)
{
for (int i = e.RowIndex; i < e.RowIndex + e.RowCount; i++)……
