dropdown selenium c# code example

Example 1: dropdown in selenium

it depends what kind of dropdown
There are 2 dropdowns 
1- HTML
2- SELECT

we determine what kind of dropdown it is
 -By tagName.We inspect.If it has <select> tag, it means it is <select> dropdown. 
 -If it is HTML, we can locate and click just as any other web element.
 
 I handle Select type of dropdown by using Select class from Selenium. 
    - Methods to select from dropdown:
        - selectByVisibleText
        - selectByValue
        - selectByIndex 
        
I verify which option is selected in a dropdown?
 - If we want to get the currently selected option, 
 we use getFirstSelectedOption() method.
        -> return type: currently selected option as a web element
        
       
--> .getOptions();
    -> This method will return all of the options in the <select> web element.
    -> return type: List<WebElement>

Example 2: dropdown in selenium

1-Select dropdowns:are created by using <select> tag in HTML
2-HTML dropdowns:these are the dropdowns that are created NOT USING <select>
These dropdowns are handled just like any other webElement. 
Select select = new Select(driver.findElement(LOCATOR));
1-selectByVisibleText(String arg); 
2-byIndex(int arg);
3-byValue:    
.getFirstSelectedOption() .getOptions(); 
.getAllSelectedOptions();.deSelectAll();
