1)dataGridView隔行变色
RowsDefaultCellStyle :获取或设置应用于 DataGridView 的行单元格的默认样式。
AlternatingRowsDefaultCellStyle 属性:获取或设置应用于 DataGridView 的奇数行的默认单元格样式。- dataGridView1.RowsDefaultCellStyle.BackColor = Color.Aqua;
- dataGridView1.AlternatingRowsDefaultCellStyle.BackColor = Color.Beige;
2)dataGridView表头加checkbox全选的方法- public class AddCheckBoxToDataGridView
- {
- public static System.Windows.Forms.DataGridView dgv;
- public static void AddFullSelect()
- {
- if (dgv.Rows.Count < 1)
- {
- return;
- }
- System.Windows.Forms.CheckBox ckBox = new System.Windows.Forms.CheckBox();
- System.Drawing.Rectangle rect = dgv.GetCellDisplayRectangle(0, -1, true);
- ckBox.Size = new System.Drawing.Size(dgv.Columns[1].Width - 12, 12); //大小
- Point point = new Point(rect.X + 10, rect.Y + 3);
- ckBox.Location = point;//位置
- ckBox.CheckedChanged += new EventHandler(ckBox_CheckedChanged);
- dgv.Controls.Add(ckBox);
- }
- static void ckBox_CheckedChanged(object sender, EventArgs e)
- {
- for (int i = 0; i < dgv.Rows.Count; i++)
- {
- dgv.Rows[i].Cells[0].Value = ((System.Windows.Forms.CheckBox)sender).Checked;
- }
- dgv.EndEdit();
- }
- }
3)鼠标拖动窗口大小时,设定窗口最小尺寸private void GetSendBankMsg_ResizeEnd(object sender, EventArgs e) { if (this.Width <= 500) this.Width = 500; if (this.Height <= 335) this.Height = 335; }
4)删除DataGridView没有数据时的默认空白行
dataGridView1.AllowUserToAddRows = false;
5)让DataGridView的所有列正好占据着整个DataGridView的宽度
把AutoSizeColumnsMode设置为FIll就行了
