Display bars in random colors:

IDictionary<string, int> list= new Dictionary<string, int>();
list.Add(“Val 1″, 90);
list.Add(“Val  2″, 89);
list.Add(“Val 3″, 50);
list.Add(“Val 5″, 87);

chrtBar2.Series["Categories"].XValueMember = “key”;
chrtBar2.Series["Categories"].YValueMembers = “value”;
chrtBar2.ChartAreas["MainChartArea"].AxisX.MajorGrid.Enabled = false;
chrtBar2.ChartAreas["MainChartArea"].AxisX.MajorTickMark.Enabled = true;
chrtBar2.ChartAreas["MainChartArea"].AxisX.MinorGrid.Enabled = false;
chrtBar2.ChartAreas["MainChartArea"].AxisX.MinorTickMark.Enabled = false;
chrtBar2.ChartAreas["MainChartArea"].AxisY.MajorGrid.Enabled = false;
chrtBar2.ChartAreas["MainChartArea"].AxisY.MajorTickMark.Enabled = true;
chrtBar2.ChartAreas["MainChartArea"].AxisY.MinorGrid.Enabled = false;
chrtBar2.ChartAreas["MainChartArea"].AxisY.MinorTickMark.Enabled = false;
chrtBar2.Series["Categories"]["PointWidth"] = “1.0″;
chrtBar2.Series["Categories"].BorderWidth = 1;
chrtBar2 .Series["Categories"].BorderColor = Color.White;
chrtBar2.DataSource = list;
chrtBar2.DataBind();

//Set random color
Random random = new Random();foreach (var item in chrtBar2.Series["Categories"].Points)

{
Color c = Color.FromArgb(random.Next(0, 255), random.Next(0, 255), random.Next(0, 255));
item.Color = c;
}

Each time will change the bar colors  when page will refreshed.

Set the active/current menu link based or Url in Jquery:

suppose we have menu like:

 <li><a href="~/url2/">URL 2</a>
 <li><a href="~/url3/">URL 3</a>
 </ul>

</div>
and user when clicked on URL 2 then item look as active :

$(function(){

    var url = window.location.pathname,
    urlRegExp = new RegExp(url.replace(/\/$/,'') + "$"); 

     $('#nav a').each(function(){
            if(urlRegExp.test(this.href.replace(/\/$/,''))){
                $(this).addClass('active');
            }
        });

                    System.Web, Version=4.0.0.0, Culture=neutral,
                    PublicKeyToken=b03f5f7f11d50a3a" />      
    </modules>
    <handlers>
      <add
            name="UrlRoutingHandler"
            preCondition="integratedMode"
            verb="*" path="UrlRouting.axd"
            type="System.Web.HttpForbiddenHandler, System.Web,  
              Version=2.0.0.0, Culture=neutral,

CheckboxList required field validation

Today I came across a situation where I need to validate CheckboxList as required field and found below solution:

//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>
