winform下gridview中的checkbox列，实现点击列头的checkbox来完成全选和不全选

Question

在winform下，gridview的checkbox列要实现全选和不全选，可以在该列的列头加个checkbox来实现吗？

Answer 1

if (this.chkAllChecked.Checked)
            {
                for (int count = 0; count < this.dgvCommon.Rows.Count; count++)
                {
                    DataGridViewCheckBoxCell cbh = (DataGridViewCheckBoxCell)this.dgvCommon.Rows[count].Cells["chkClient"];
                    this.dgvCommon.Rows[count].Cells["chkClient"].Value = true;
                    this.dgvCommon.SelectAll();
                }
            }
            else
            {
                for (int count = 0; count < this.dgvCommon.Rows.Count; count++)
                {
                    DataGridViewCheckBoxCell cbh = (DataGridViewCheckBoxCell)this.dgvCommon.Rows[count].Cells["chkClient"];
                    this.dgvCommon.Rows[count].Cells["chkClient"].Value = false;
                    this.dgvCommon.ClearSelection();
                }
            }
以下是行的全选代码,只需红色部分就可以

Answer 2

        private void checkBoxAll_CheckedChanged(object sender, EventArgs e)
        {
            if (checkBoxAll.Checked)
            {
                foreach (DataGridViewRow myDgvr in dataGridView1.Rows)
                {
                    myDgvr.Cells["Xuan"].Value = 1;
                }
            }
            else
            {
                foreach (DataGridViewRow myDgvr in dataGridView1.Rows)
                {
                    myDgvr.Cells["Xuan"].Value = 0;
                }
            }
        }

Answer 3

错了:用下面这个.if (this.你要点击的checkbox.Checked)
            {
                for (int count = 0; count < this.datagridview1.Rows.Count; count++)
                {
                    DataGridViewCheckBoxCell cbh = (DataGridViewCheckBoxCell)this.dgvCommon.Rows[count].Cells["你的checkbox"];
                    this.datagridview1.Rows[count].Cells["你的checkbox"].Value = true;
                }
            }
            else
            {
                for (int count = 0; count < this.datagridview1.Rows.Count; count++)
                {
                    DataGridViewCheckBoxCell cbh = (DataGridViewCheckBoxCell)this.dgvCommon.Rows[count].Cells["你的checkbox"];
                    this.datagridview1.Rows[count].Cells["你的checkbox"].Value = false;
                }
            }

Answer 4

忘记说了，dataGridView1 中那个checkBox的TrueValue为1，FalseValue为0

Answer 5

我是想在checkbox的列头上也加个checkbox，就像网页上那样的效果，勾上列头的checkbox就全选，下面列中的，不够下面单元格的也都不选啊~
