How to give a space bar command after sending values by sendKeys?

I want to send space bar after entering values in the textbox
driver.FindElement(By.Id(“texbar”)).SendKeys(“06514”);
after populating the field, enter space bar.
I tried .SendKeys("06514 ");
it do creates a space after value but not giving me the result that i get after pressing space bar from key board.

I am also facing the same issue . Please suggest.
