Hi, You can try out this. It works fine. protected void Page_Load( object sender, EventArgs e) { lblDisplayDate.Text = System. DateTime .Now.ToString( "T" ); } protected void btnPostback_Click( object sender, EventArgs e) { System.Text. StringBuilder sb = new System.Text. StringBuilder (); sb.Append( @" " ); sb.Append( @"var lbl = document.getElementById('lblDisplayDate');" ); sb.Append( @"lbl.style.color='red';" ); sb.Append( @" " ); if (!ClientScript.IsStartupScriptRegistered( "JSScript" )) { ClientScript.RegisterStartupScript( this .GetType(), "JSScript" , sb.ToString()); } } While clicking the Postback button the date label color will be changed as Red. Let me know if you have doubt. Hope this helps you. !
