Why Is This JQuery Not Sliding Down/showing Hidden (slid Up) Elements?

I create rows with IDs of foapalrow3 and foapalrow4 in C#, making them temporarily invisible: foapalrow3 = new HtmlTableRow(); foapalrow3.ID = 'foapalrow3'; . . . foapalrow3.Visibl

Solution 1:

You could check for the display property using

$('[id$=foapalrow4]').is(":visible");
