Checking and unchecking of a checkbox using Selenium WebDriver - selenium

Question

Checking and unchecking of a checkbox using Selenium WebDriver.
I am using the page object pattern, so my code appears this way.
SelectCheckBox("Check"); OR SelectCheckBox("Uncheck");
[FindsBy(How = How.Id, Using = "payment_sameasdeliveryaddress")]
public IWebElement checkbox_Address = null;
public void SetCheckBox(string value)
{
//Console.Write("checkbox state: " + checkbox_Address.Selected);
if (value.ToLower().Equals("uncheck") && checkbox_Address.Selected)
{
checkbox_Address.Click();
}
else if (value.ToLower().Equals("check") && !checkbox_Address.Selected)
{
checkbox_Address.Click();
}

Answer 1

It has been years since I wrote any .NET, so the below may not even compile! But hopefully you get the idea.
// The individual elements should be declared private
private IWebElement payment_sameasdeliveryaddress;
// If you name it same as the source element
// ID, PageFactory will find it for you
// flag = true, means you want it checked
public void SelectCheckBox(Boolean check)
{
if (!check && payment_sameasdeliveryaddress.Selected) {
payment_sameasdeliveryaddress.Click();
}
else if (check && !payment_sameasdeliveryaddress.Selected) {
payment_sameasdeliveryaddress.Click();
}

Answer 2

The simplest way of checking a checkbox is checked or not by using the isSelected() method with an element. For example:
if(getCheckBox().isSelected()){
getCheckBox.click();
}
public WebElement getCheckBox(){
return driver.findElement(termsCheck);
}

Answer 3

This would also work:
// flag = true, means you want it checked
public void SelectCheckBox(Boolean check)
{
if (check ^ payment_sameasdeliveryaddress.Selected) {
payment_sameasdeliveryaddress.Click();
}
}

Sharing the snippet that's just implemented in the current project using Selenium WebDriver 3.9.1 and TestNG 6.14.
// Returns boolean value based on whether check-box is selected or not
Boolean chkBx1Sel = driver.findElement(By.xpath(elementXpath)).isSelected();
Case 1: Check a check-box
if(dataValofChkBx != null && dataValofChkBx.equalsIgnoreCase("Y"))
{
if(chkBx1Sel.toString() == "false") //i.e., checkbox is not already checked
{
driver.findElement(By.xpath(POP2GUIConstants.ggsnFwlfUpdChkBx)).click();
}
}
Case 2: Uncheck a check-box
if(dataValofChkBx != null && dataValofChkBx.equalsIgnoreCase("N"))
{
if(chkBx1Sel.toString() == "true") // I.e., checkbox is already checked
{
driver.findElement(By.xpath(POP2GUIConstants.ggsnFwlfUpdChkBx)).click();
}
}
