Question

C# 怎么得到gridview控件中模版列中的多行CheckBox的索引

Answer 1

function checkall(c) {
var chk = document.getElementsByTagName("input");
var ids = "";
for (var i = 0; i < chk.length; i++) {
if (chk[i].type == "checkbox") {
chk[i].checked = c.checked;
}
}
}
上面是全选或全不选的代码
下面是gridview的 TemplateField
<asp:TemplateField ItemStyle-HorizontalAlign="Center">
<HeaderTemplate>
<input id="cboall" onclick="checkall(this)" type="checkbox" />
</HeaderTemplate>
<ItemTemplate>
<input type='checkbox' id='selid' name='selid' value='<%#Eval("ID")%>' runat="server" />
</ItemTemplate>
<HeaderStyle ForeColor="White" />
<ItemStyle HorizontalAlign="Center" />
</asp:TemplateField>
