How to return same page after getting login?

Sometime we need to create user(if new) or login(Authenticate) to view particular page.
and after user is logged in, we need to return him to the same page.

And if new account is created user should logged-in and then need to return him to the same page.

to achieve this we can user Request.UrlReferrer property and can redirect back to original URL.

On Page_Load event

     protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                ViewState["ReferrerUrl"] = Request.UrlReferrer.ToString();
            }
        }

Function to return to same page.

        private void ReturnBackExistingUser()
        {
            object referrer = ViewState["ReferrerUrl"];

            if (referrer != null)
            {
                Response.Redirect(referrer.ToString());
            }
            else
            {
                Response.Redirect("Default.aspx");
            }
        }


If we have created new user then Add one line in function to authenticate new user.

FormsAuthentication.SetAuthCookie(username, false);

where username is newly created aspnet user.

so function to authenticate new user and then  return him to the same page is:
 
      private void ReturnBackNewUser()
        {
            FormsAuthentication.SetAuthCookie(username, false);

            object referrer = ViewState["ReferrerUrl"];

            if (referrer != null)
            {
                Response.Redirect(referrer.ToString());
            }
            else
            {
                Response.Redirect("Default.aspx");
            }
        }

C#: Merging Excel cells with NPOI HSSFWorkbook

In this post we’ll see how to merge the two or more cell with each other while creating the excel sheet using NPOI.
Mentioned below is code to merge multiple cells, in this example we are merging first cell to fifth cell of first row (you can adjust row or cell range by passing particular parameters in CellRangeAddress).
//Created new Workbook var hwb = new NPOI.HSSF.UserModel.HSSFWorkbook(); //Create worksheet with name. var sheet = hwb.CreateSheet("new sheet"); //Create row and cell. var row = sheet.CreateRow(0); var cell = row.CreateCell(0); ; //Set text inside cell cell.SetCellValue("This is Merged cell"); cell.CellStyle.WrapText = true; //define cell range address // parameters: -> first row to last and first cell to last cell var cra = new NPOI.SS.Util.CellRangeAddress(0, 0, 0, 4); //Add merged region to sheet. sheet.AddMergedRegion(cra);
Hope this solution helps you J

Read and parse a CSV file into an array of rows and columns in C#

The following PopulateCsvIntoArraymethod used to read the CSV file into a two-dimensional array of strings.
I have included explanation of method lines, wherever needed. ///<summary> /// Populate the CSV file into an array, /// We assume that every line has the same number of fields and there may be blank lines. ///</summary> ///<returns></returns> privatestring[,] PopulateCsvIntoArray() { // Get path of CSV file. var path = Server.MapPath("~/Folder_Name/testfile.csv"); // Get the file's text using ReadAllText method. string fileData = System.IO.File.ReadAllText(path);
// Split CSV data into lines.     fileData = fileData.Replace('\n', '\r'); string[] lines = fileData.Split(newchar[] { '\r' }, StringSplitOptions.RemoveEmptyEntries);
// Get rows and columns counts. int totalRows = lines.Length;

Calculate Sum and average of two or more Textbox values using JQuery

We can calculate sum and average of values entered in textboxes with the help of small piece of jQuery code.
First of all let’s create a HTML form where we’ll ask user to enter marks in each subject, under body section add following HTML:
<tableclass="demo-table"> <trclass="label"> <tdcolspan="2">Please enter marks(0-99):</td> </tr> <tr> <td>English</td> <td> <inputtype="text"class="txtMarks"name="txtMarks"
