Selenium CSS selector throwing OpenQA.Selenium.InvalidSelectorException - what's wrong?

I am attempting to find a table cell using a CSS selector in Selenium. This is my selector:

//table[@id='prepaymentItemsDataGrid']//tr[@class='tablerowlight']/td[3]

The exception being thrown is:

Driver.FindElementByCssSelector("//table[@id='prepaymentItemsDataGrid']//tr[@class='tablerowlight']/td[3]") threw an exception of type 'OpenQA.Selenium.InvalidSelectorException'

What is wrong with my selector? How do I know what Selenium is complaining about?

I have tried simplifying it to:

//table[@id='prepaymentItemsDataGrid']

which has no effect.

Does Selenium have a different method of executing CSS selectors and how can I check that the selector is valid before trying to run it?

Though you have tried to use FindElementByCssSelector() but the values were of XPath. You can use either of the following Locator Strategies :

  • CssSelector :

    Driver.FindElementByCssSelector("table#prepaymentItemsDataGrid tr.tablerowlight > td:nth-of-type(3)");

  • XPath :

    Driver.FindElementXPath("//table[@id='prepaymentItemsDataGrid']//tr[@class='tablerowlight']/td[3]");
