如何实现?
------解决方案--------------------------------------------------------
ItemDataBind(....)
{
if(e.Row.RowType=DataControlRowType.Header)
{
CheckBox checkbox=e.Row.FindControl( "checboxID ") as CheckBox;
checkbox.Attributes.Add( "onclick ", "checkAllBox(); ");
}
}
Aspx
<script language= "javascript ">
function checkAllBox()
{
var k=document.getElementsByName( "AllcheckBox ");
for(var i=0;i <k.length;i++)
{
k[i].checked=true;
}
}
</script>
注意模版项checkBox应该用客户端的.<input type= "checkbox " name= "AllcheckBox " vaule= " <%# Eval( "主键 ")%> ">
接收checkBox选种的值this.Request[ "AllcheckBox "]; 会得到pk1,pk2,的数组
