C# 中的DataGridView控件如何设置成具有复选框功能？

runat="server" name="chids" />

Font-Underline="False" HorizontalAlign="Center" />

DataFormatString='{0:d}'>

--%>

ImageAlign="AbsMiddle">

//全选
function selectAll(SourceID, ControlID) {
var sourceBox = document.getElementById(SourceID)
var theBox = document.all(ControlID)

elm = theBox.getElementsByTagName('Input')
for (i = 0i < elm.lengthi++) {
if (elm[i].type == "checkbox") {
elm[i].checked = sourceBox.checked
}
}
}
//选择删除检测
function CheckNULL(ControlID) {
var isNULL = false
var theBox = document.all(ControlID)
elm = theBox.getElementsByTagName('Input')

for (var i = 0i < elm.lengthi++) {
var e = elm[i]
if (e.type == "checkbox" && e.checked == true && e.id != "chkAllInBox") {
isNULL = true
}
}
if (isNULL == false) {
alert('请选择删除项！')
return false
}
else {
return confirm('确定要删除信息？')
}
}
