推荐答案

如果您正在寻找Checkbox列表所需的验证，请查看此代码，否则发布您的要求.

If you are looking required validation for Checkbox list then look into this code otherwise post your requirement.

//Bound list from Database
<asp:checkboxlist id="chlZones" runat="server" repeatcolumns="5" repeatdirection="Horizontal" />
//Create Custom validator that will work as required validator. Profile function
<asp:customvalidator id="cvalZones" runat="server" clientvalidationfunction="ValidateZones" errormessage="!!!" display="Dynamic" />
 
//Implement Client method
<script>
function ValidateZones(source, args) {
		var chlZones = document.getElementById('''');
		var chkLista = chlZones.getElementsByTagName("input");
		for (var i = 0; i < chkLista.length; i++) {
			if (chkLista[i].checked) {
				args.IsValid = true;
				return;
			}
		}
		args.IsValid = false;
	}
</script>
