private void FrmLog_Load(object sender, EventArgs e)
{
dataGridView1.DataSource = SQLiteHelper.GetTable("select * from log");
dataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
dataGridView1.AutoGenerateColumns = false;
dataGridView1.ReadOnly = true;
dataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.Fill;
dataGridView1.AllowUserToAddRows = false;
}
在dataGridView1的RowPostPaint事件中，添加下如下代码。
private void dataGridView1_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
{
SolidBrush b = new SolidBrush(this.dataGridView1.RowHeadersDefaultCellStyle.ForeColor);
e.Graphics.DrawString((e.RowIndex + 1).ToString(System.Globalization.CultureInfo.CurrentUICulture), this.dataGridView1.DefaultCellStyle.Font, b, e.RowBounds.Location.X + 20, e.RowBounds.Location.Y + 4);
}
获取选中行的值
private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
if (e.RowIndex > -1)
{
int rowindex = e.RowIndex;
txtLogId.Text = dataGridView1.Rows[rowindex].Cells[0].Value.ToString(); //获得当前行的第1列的值
}
}
