GridView的CheckBox列选择及多参数传递三步搞定

<asp:TemplateField HeaderStyle-CssClass="check" ItemStyle-CssClass="check">
<HeaderTemplate>
<input type="checkbox" onclick="selectAll(this)" />
全选
</HeaderTemplate>
<ItemTemplate>
<input name="chkIDCardNum" type="checkbox"
value="<%# Eval("PID") %>$<%# Eval("IdentityCard")%>$<%# Eval("PName")%>"
<%# "1" == Eval("IsCouldDelete").ToString()?"disabled=disabled":""%> />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField Visible="true" HeaderText="删除">
<ItemTemplate>
<asp:LinkButton id="lbtnDelete" CommandName="lbtnDelete" runat="server" Text="删除档案"
CommandArgument=<%# Eval("PID") +"$"+ Eval("IdentityCard")%>
OnClientClick="return confirm(确认删除？);"
Visible=<%# Eval("Termination").ToString()=="1" ? false : true %> />
</ItemTemplate>
</asp:TemplateField>

function selectAll(myself) {
var oState = myself.checked;
var checkboxes = document.getElementsByName("chkIDCardNum"); //获取input组
for (var i = 0; i < checkboxes.length; i++) {
if (checkboxes[i].disabled) {
} else {
checkboxes[i].checked = oState; //选择值
}
}
}

var selectedIds = Request.Params["chkIDCardNum"].Split(,);
if (selectedIds.Length == 0)
return;
//int[] msgIds = Array.ConvertAll<string, int>(selectedIds, s => int.Parse(s));
int[] ids = selectedIds.Select(t => int.Parse(t.Split($)[0])).ToArray();
string[] cards = selectedIds.Select(t => t.Split($)[1]).ToArray();
