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

}

}
