这个不需要再事件中实现啊,在javascript中很容易实现的
#3
是datagridview不是gridiview ,二者之间有区别的。。
#4
网上太多了。。。。。
#5
没有人回答吗?
#6
datagridview不是winform中的吗?怎么到asp.net区来问?
dgv1.EndEdit();
foreach (DataGridViewRow dgvr in dgv1.Rows)
{
dgvr.Cells["Check"].Value = checkState;
}
Check就是你的列名
dgv1.EndEdit();
foreach (DataGridViewRow dgvr in dgv1.Rows)
{
dgvr.Cells["Check"].Value = checkState;
}
Check就是你的列名

#region 选择CheckBox
DatagridViewCheckBoxHeaderCell cbhCell = new DatagridViewCheckBoxHeaderCell();
cbhCell.OnCheckBoxClicked += new CheckBoxClickedHandler(cbhCell_OnCheckBoxClicked);
DataGridViewCheckBoxColumn cbCheck = new DataGridViewCheckBoxColumn();
cbCheck.HeaderCell = cbhCell;
cbCheck.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter;
cbCheck.ReadOnly = false;
cbCheck.Name = "Check";
cbCheck.Width = 40;
cbCheck.HeaderCell.Value = string.Empty;
#endregion
private void cbhCell_OnCheckBoxClicked(bool checkState)
{
dgv1.EndEdit();
foreach (DataGridViewRow dgvr in dgv1.Rows)
{
dgvr.Cells["Check"].Value = checkState;
}
}
DatagridViewCheckBoxHeaderCell cbhCell = new DatagridViewCheckBoxHeaderCell();
cbhCell.OnCheckBoxClicked += new CheckBoxClickedHandler(cbhCell_OnCheckBoxClicked);
DataGridViewCheckBoxColumn cbCheck = new DataGridViewCheckBoxColumn();
cbCheck.HeaderCell = cbhCell;

cbhCell.OnCheckBoxClicked += new CheckBoxClickedHandler(cbhCell_OnCheckBoxClicked);
这一句是为列标题添加事件
