To enable disable all the buttons of html form needs to write lots of code in JavaScript. In JavaScript first we need to find all input elements which having input type submit and store it in array. After storing elements in array needs to loop that array and disable or enable element one by one. Instead of writing lots of code we can use JQuery one line code as follows $('input[type=submit']).attr('disabled',true); The above JQuery code will disable all input elements which having type submit. Happy coding...............

In Jquery, you need to write one line code to get value of dropdownlist. You can use following code to get value of selected option Var selectvalue=$('#urid').val(); You can use following code to get text of selected option Var selecttext=$('#urid').text(); you are done......   Happy coding...........

I have learnt last week Linq to sql and i amazed by its features.I would like to share my knowledge with you.To insert,update and delete you need to write lesser amount of code hence it saves development time. Following is the step you need to follow in order to insert,update and delete data of database using Linq to sql in Asp.Net. Open Visual Studio 2008, Click File >Website and choose ASP.Net Website. Choose the language of your choice and name your website according to your need. In solution explorer, right the project and select “Add New Item”. Select “LINQ to SQL classes” as shown in below figure. I have named it as DataClasses1. This will add an EmployeeInfo.dbml file inside “App_Code” folder.    In Visual Studio,   DataClasses1.dbml will have 2 panes. The left pane is for deigning the data objects and the right pane can be used for creating methods that operates on the data objects.The Visual Studio toolbar will contain a new toolbar for designing LINQ to SQL obje

Linq to sql is a microsofts powerful tool to develop critical application faster.In Linq to sql the query result is in Generic list of generic  ienumerable type.  If you want result set in DataTable you need to convert this generic list result into datatable. To convert LINQ to SQL results into a DataTable use following Code DataClassesDataContext dc=new DataClassesDataContext(); var results = dc.products.ToList(); DataTable dt = new DataTable(); List<product> lst = results; PropertyInfo[] props= typeof(product).GetProperties(); foreach (var prop in props) { dt.Columns.Add(prop.Name); } foreach (var item in lst) { var rowa = new object[props.Length]; for (int i = 0; i < props.Length; i++) { rowa[i] = props[i].GetValue(item, null); } dt.Rows.Add(rowa); } Gr

Use following JavaScript function to add comma in numeric input in textbox function Comma(Num) { Num += ''; Num = Num.replace(/,/g, ''); x = Num.split('.'); x1 = x[0]; x2 = x.length > 1 ? '.' + x[1] : ''; var rgx = /(\d)((\d)(\d{2}?)+)$/; while (rgx.test(x1)) x1 = x1.replace(rgx, '$1' + ',' + '$2'); return x1 + x2; } Use following event of input textbox to call above function onkeyup = "javascript:this.value=Comma(this.value);"

Problem: We put  autopostback controls like textbox, DropDownList controls inside in update panel to reducing the flickering of the Page.but when user uses tab for entering the details  the focus of the control losts. Web site users who prefer to use keyboard need to use mouse to activate appropriate input box or press TAB multiple times. Solution: Step 1: Save following in js file give any name to it (like MyUpdatePanelFocus.js ) var lastFocusedControlId = ""; function focusHandler(e) { document.activeElement = e.originalTarget; } function appInit() { if (typeof (window.addEventListener) !== "undefined") { window.addEventListener("focus", focusHandler, true); } Sys.WebForms.PageRequestManager.getInstance().add_pageLoading(pageLoadingHandler); Sys.WebForms.PageRequestManager.getInstance().add_pageLoaded(pageLoadedHandler); } function pageLoadingHandler(sender, args) { lastFocusedControlId = typeof (document.acti
