Note : If any runtime error occurred by running our downloaded project meaning of that your browser version and Selenium API DLL version is not matching. To resolve this issue you need to download latest Selenium C# API DLLs from this link and paste downloaded DLLs into 'Bin' folder of downloaded project. Or you can remove references of existing DLLs references and add new DLLs references. You can learn this thing from this link.

Using selenium C# webdriver API we are able to insert text in website textbox element automatically in web browser. This article is very useful for automate website testing.

To enter text in textbox we need locator string of that particular textbox. To get locator string you need to your FireFox Element Locator Add-on.

Here is example for insert text in textbox automatically:
In this example first we open website 'www.google.com'. After that, we locate search textbox using locator add-on. Now in C# code we create object of FireFoxDriver Class.

We are using 'FindElement' method of 'FireFoxDriver' Class object, in this object we are finding element using 'XPath'. We are using 'OpenQA.Selenium.By.XPath' method. After finding element we are using 'SendKeys' method to insert text in textbox.

In 'SendKeys' method's parameter pass your desire text or string. This method exist in 'OpenQA.Selenium.IWebDriver.ISearchContext.FindElement' class.

Selenium C# Code :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Selenium;
using OpenQA;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

        OpenQA.Selenium.IWebDriver objFF = new OpenQA.Selenium.Firefox.FirefoxDriver();
        objFF.Navigate();
        objFF.Url = "http://www.google.com";
        objFF.FindElement(OpenQA.Selenium.By.XPath("//input[@id='gbqfq']")).SendKeys("ASP.NET");
                
    }
}

• driver.FindElement(By.XPath("//input[@id='gbqfq']"));
• driver.FindElement(By.XPath("//input[@name='q']"));
• driver.FindElement(By.XPath("//input[@role='combobox']"));
• driver.FindElement(By.XPath("//input[contains(@id,'gbqfq')]"));

Now to locate an element first you need to download and install FireFox Element Locator Add-on.

This would be useful in condition like you need to perform some operation on DataTable using LINQ and get back result into another 'DataTable'. Means, you can filter and projection on one DataTable and get result in another DataTable.

We can achieve this by using 'CopyToDataTable' method of LINQ query result variable.

Here is example for this.
In this example we are taking one DataTable which contains product information like ID, name, etc. Now we get only those products which ID is greater than one by LINQ operation on this table and get result in another table using 'CopyToDataTable' method of LINQ query result variable.

In this example we take one "Book.xml" file. In this file we have element like Title, Pages, ISBN and Auther. Now we are querying the "Book.xml" file to get only Title and ISBN of book and create another XML with data that contains only Title and ISBN element.

.Net Tips : Convert DataTable object to list of class object using LINQ with C#.Net and VB.Net example

You can fill List of object from DataTable using LINQ. There are many situations where you need to get data from DB into data table and after that from data table to proper class object. We can do this easily with LINQ.

Here is example for this.
In this example we take one DataTable object which contains two columns 'product_id' and 'product_name'. This DataTable has many rows. Now we want to convert DataTable object into list of class object. We have one Class 'clsProduct' which has two property 'product_id' and 'product_name'. Now we transform DataTable object data in to list of clsProduct class object using LINQ.

MVC Tips : Implement IValidatableObject Interface for custom validation in ASP.Net MVC 4

Click Here to Download ImplementIValidateObjectInterfaceInMVC.zip Example.

We can validate model itself by implementing IValidatableObject Interface. For validation you need to implement 'Validate' method of IValidatableObject Interface.

Here is some difference from the attribute validation version.

• In this for validation method is 'Validate' instead of 'IsValid' and also return type and parameter is different.
• The return type for Validate is an IEnumerable<ValidationResult>, because the logic inside this method is validating the entire model and might need to return more than a single validation error.
• No parameter is passed to Validate because you  can directly access model properties because this Validate method is inside model.

Here is example for this.

.Net Tips : Attach and Raise events on XML document object with C#.Net and VB.Net example

You can attach events like 'onChanging' and 'onChanged' events on XML document object. These events raise when you 'ADD' or 'REMOVE' XML element from XML Document object.

First 'onChanging' event raise after that 'onChanged' event raise. In this event we get 'XObjectChangeEventArgs' class object. This object give us property like 'ObjectChange'. In this property we can know that which method is performed.

When we call 'Add' method we get 'Add' value in 'ObjectChange' property and when we call 'Remove' method we get 'Remove' value in 'ObjectChange' property.

Here is example on this.

MVC Tips : Custom Annotation validation in ASP.Net MVC 4

Click Here to Download CustomAnnotationInMVC.zip Example.

You can write your own custom annotations in MVC 4.
Here we can do custom validation using custom annotations. Custom annotations validation derive from the ValidationAttribute base class. This base class available in 'System.ComponentModel.DataAnnotations' namespace. ValidationAttribute class is abstract class.

For custom validation you need to write your own class and inherit ValidationAttribute class. After that, you need to override IsValid Method. IsValid Method has two parameters 'Value' and 'ValidationContext'.

• Value : Which contains your data, which is going to validate.
• ValidationContext : This parameter is very important. This content information like model object instance, model type friendly display name and other information

In this method you write your own logic for validate data and return result. If value is validate at that time you need to return this 'ValidationResult.Success' else you return result like 'return new ValidationResult(your custom error message)'
