The type or namespace SelectElement could not be found in selenium c#

Question

driver.FindElement(By.Id(\"inputPassword\")).SendKeys(\"123\");
driver.FindElement(By.TagName(\"butto         


        

Answer 1

Selenium WebDriver C# code for selecting item from Drop Down:

IWebElement selectElement = driver.FindElement(By.Id("selectFilterbyUser"));
SelectElement oSelect = new SelectElement(selectElement);

There are 3 ways to select drop down item: byText, byIndex, byValue

1.byText()

oSelect.SelectByText("Alex");

2.byIndex()

SelectAnEducation.SelectByIndex(0);

3.byValue()

SelectAnEducation.SelectByValue("Alex");

Hope this helps,

Answer 2

First of all, You need to install the proper package from NuGet which is Selenium.Support

Correct using statements is as:

using OpenQA.Selenium.Support.UI;

Answer 3

You need to make sure to reference the NuGet Package Selenium.Support.

I was having the same issue and then realized that I was only referencing the Selenium.WebDriver NuGet Package. After adding the Selenium.Support NuGet package, and adding the proper using statements. My SelectElement code successfully compiled.

The proper using statements

using OpenQA.Selenium;
using OpenQA.Selenium.Support.UI;

Answer 4

I had the same issue due to using the pre-release version. v4.00 alpha. I installed the previous version v3.141.0 and the errors were resolved

Answer 5

Referring to a few previous posts it seems if you are using frameworks like nunittestadapter, NUnit.Framework, VS 2017 using the NuGet Manager sometimes there can be issues with the installation /configuration.

SelectElement Class

As per the documentation the SelectElement Class is pretty much available within OpenQA.Selenium.Support.UI Namespace which provides a convenience method for manipulating selections of options in an HTML select element.
