This is simple way to implement the numeric validation on textbox or input control using jquery. Firstly you need to use jquery selector for binding the keydown event to input control. Once you bind it it will only allow numeric keys and reject the alphabetical keys. Following is the code snippet of the numeric validation using Jquery. $(document).ready(function () { $("#MobileNo").keydown(function (e) { // Allow: backspace, delete, tab, escape, enter and . if ($.inArray(e.keyCode, [46, 8, 9, 27, 13, 110, 190]) !== -1 || // Allow: Ctrl+A (e.keyCode == 65 && e.ctrlKey === true) || // Allow: home, end, left, right, down, up (e.keyCode >= 35 && e.keyCode <= 40)) { // let it happen, don't do anything return; } // Ensure that it is a number and stop the keypress if ((e.shiftKey || (e.keyCode < 48 || e.k

Callback is another fabulous way to communicate with server for light weight tasks. While working in ASP.NET, sometimes we need to call server side methods asynchronously without having a postback. Sometimes it is either a full page postback or partial page postback. To Implement callback in asp.net following interfaces to me implement in the asp.net page ICallback ICallbackEventHandler Let us first implement ICallbackEventHandler to call the server side method asynchronously step-by-step. The following are the definition of two methods which we need to implement. RaiseCallbackEvent method invoke through JavaScript function. public void RaiseCallbackEvent(string eventArgument) { //populate Customer object to return Customer customer = new Customer(); customer.Name = "Muhammad Adnan"; customer.Age = 24; //javascript serialization of Customer object System.Web.Script.Serialization.JavaScriptSerializer jss; jss = new System.Web.Script.Serializa

This is simple example of taking database backup from the sql script. In my example I have illustrated the simplest way to take the back up from the database. I have used the cursor for the same.    Following is the code of the Backup script. DECLARE @name VARCHAR(50) -- database name DECLARE @path VARCHAR(256) -- path for backup files DECLARE @fileName VARCHAR(256) -- filename for backup DECLARE @fileDate VARCHAR(20) -- used for file name SET @path = 'C:\Backup\' SELECT @fileDate = CONVERT(VARCHAR(20),GETDATE(),112) DECLARE db_cursor CURSOR FOR SELECT name FROM master.dbo.sysdatabases WHERE name NOT IN ('master','model','msdb','tempdb') OPEN db_cursor FETCH NEXT FROM db_cursor INTO @name WHILE @@FETCH_STATUS = 0 BEGIN SET @fileName = @path + @name + '_' + @fileDate + '.BAK' BACKUP DATABASE @name TO DISK = @fileName FETCH NEXT FROM db_cursor INTO @name END CLOSE db_cursor DEAL

I am going to demonstrate in this article about importing CSV file data into datatable and then bind that data to Asp.net gridview control. I have tried to make code simpler and less line of code. I am assuming that you have saved the csv file to server by using file-upload control. After that create function which returns string[] private IEnumerable<string[]> GetAllDataFromCSVFile(string FileName) { string str; using (StreamReader rd=new StreamReader(FileName)) { while ((str = rd.ReadLine()) != null) { yield return str.Split(','); } } } Create another function which returns final data-table with CSV File data private DataTable GetCSVData(string FileName) { var values = GetAllDataFromCSVFile(FileName); DataTable dt = new DataTable(); int j=0; foreach (var

In this Article, I am going to demonstrate to fill the dropdownlist with J query using JSON in asp.net mvc3 . To achieve this task we need to write the following JavaScript code in view ( .cshtml page). @{ ViewBag.Title = "Products"; } <script type="text/javascript"> jquery(document).ready(function () { jquery("ddlCategory").change(function () { var idModel = jquery("#ddlCategory").val(); jquery.getJSON("product/items/", { category: idModel }, function (carData) { var select =jquery("#ddlitems"); select.empty(); select.append($('<option/>', { value: 0, text: "" })); jquery.each(carData, function (index, itemData) {

To  redirect the page in new window there is no readymade methode in asp.net. To overcome this lack of readymade function, we need to do some custom coding and it will only achieve by using javascript Window.Open Methode. I have created the methode in c#.nnet to redirect the desired page in new window. Following is my methode defination.. public static void Redirect(string url, string target, string windowFeatures) { HttpContext context = HttpContext.Current; Page page = (Page)context.Handler; string script; if (!String.IsNullOrEmpty(windowFeatures)) { script = @"window.open(""{0}"", ""{1}"", ""{2}"");"; } else { script = @"window.open(""{0}"", ""{1}"");"; } script = String.Format(script, url

Convert rows into columns in sql server database? We're going to see how to do that using different query, and there is the "Pivot" function in SQL Server 2005.     Example: We are using two tables: Subject which is a lookup table that holds the subject names, and the StudentSubject which contains the student grades for the different subject. We are going to build the query having fixed columns: We can use the "case"  statement in the query to convert rows into columns. SELECT StudentId, SUM(Physics) AS Physics, SUM(Chemistry) As Chemistry, SUM(Math) AS Math, SUM(English) As English FROM (SELECT StudentId, (CASE SubjectId WHEN 24 THEN ISNULL(Grade, 0) END) AS Physics, (CASE SubjectId WHEN 25 THEN ISNULL(Grade, 0) END) AS Chemistry, (CASE SubjectId WHEN 26 THEN ISNULL(Grade, 0) END) As Math, (CASE SubjectId WHEN 28 THEN ISNULL(Grade, 0) END) AS English FROM Student_Subject) s GROUP BY StudentId Now, we can convert rows into columns

When user selects particular row of gridview then that row should be highlighted. but in asp.net you do not have mechanism to to this task automatically. For this purpose you need to write some custom code, which includes some JavaScript code. to highlight the row selected by user follow the step below For this you have to write this code in your code behind file in OnRowCreated event or your can also write this code in OnRowDataBound event of grid... protected void ctlGridView_OnRowCreated(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { e.Row.Attributes.Add("onclick", "onGridViewRowSelected('" + e.Row.RowIndex.ToString() + "')"); } } then add following script to your aspx page in script tag <script language="javascript" type="text/javascript"> var gridViewCtlId = '<%=ctlGridView.ClientID%>

Root your Gingerbread 2.3.4 android Mobile Phone with following steps. before you start you have to download some files from here and follow the steps below  Put the phone in Debug Mode: Go to Settings > Applications > Development and check USB debugging box. Extract the files from the zip below, connect the phone via USB, and copy them to the phone via ADB like this: Code: adb push Superuser.apk /sdcard/Superuser.apk adb push su /sdcard/su adb push busybox /sdcard/busybox adb push exploit.bin /data/local/tmp/exploit.bin   Now we enter the phone's internal shell, also using ADB: Code: adb shell Then we take advantage of the "fake" root exploit: Code: cd /data/local/tmp chmod 0755 exploit.bin ./exploit.bin Now after that last command you should be back to your normal console, not the phone one, so we need to connect to it again, and doing so we should now see that we have root permissions since the "#" symbol is displayed

Hi all, here i am going to demostrate about the proxy settings in android phone. As there is no UI for proxy settings for android web browser. But the android web browser will read the proxy settings in its settings database. Here is the instructions to enable the proxy in the android web browser. to do this setting you must download SDK package from android you need to check USB Debugging option in phones setting and follow the step given below > adb shell # sqlite3 /data/data/com.google.android.providers.settings/databases/settings.db sqlite> INSERT INTO system VALUES(99,’http_proxy’, ‘proxy:port’); sqlite>.exit You can talk to settings.db for more information. sqlite> SELECT * FROM system; sqlite> .tables sqlite> .databases sqlite> .schema table_name sqlite> more SQL expression to talk to the tables Don’t forget the ‘;’ at the end of the SQL expression.
