I forgot how autogenerated gridview HTML markup is rendered in the browser, but you can try escaping the first <tr> of the table. Your code would now look something like this:

JavaScript

$('input[id$=txtSearch]').keyup(function () {
	_this = this;

	$.each($("[id*=grd]").find("tr:not(:first)"), function () {
		if ($(this).text().toLowerCase().indexOf($(_this).val().toLowerCase()) == -1)
			$(this).hide();
		else
			$(this).show();
	});

});

The key there is to use the jQuery selector tr:not(:first) to prevent the first row to be hidden.

You can also try looking at QuickSearch plugin as demontrated in this article here: https://www.aspsnippets.com/Articles/Implement-Client-Side-search-in-GridView-using-jQuery-in-ASPNet.aspx[^]
