If you use jQuery for validation, then it will be a client only validation. You should have a server side validation as well. So use asp.net validator controls

XML

<html>
<head>
<meta charset="utf-8">
<title>Makes "field" always required. Nothing and blanks are invalid.</title>
<link rel="stylesheet" href="http://jquery.bassistance.de/validate/demo/site-demos.css">
</head>
<body>
<form id="myform">
<label for="field">Required: </label>
<input type="text" class="left" id="field" name="field">
<br/>
<input type="submit" value="Validate!">
</form>
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script src="http://jquery.bassistance.de/validate/jquery.validate.js"></script>
<script src="http://jquery.bassistance.de/validate/additional-methods.js"></script>
<script>
// just for the demos, avoids form submit
jQuery.validator.setDefaults({
debug: true,
success: "valid"
});
$( "#myform" ).validate({
rules: {
field: {
required: true
}
}
});
</script>
</body>
</html>

On Button's OnClientClick Event, call one JavaScript function.

ASP.NET

<asp:Button OnClientClick="return validate()" runat="server"></asp:Button>

Inside that function, check if TextBox contains data or not by JavaScript document.getElementById() or jQuery $ selector.

JavaScript

function validate()
{
    var yourTextbox = document.getElementById("textBoxId");
 
    if(yourTextbox.value == null || yourTextbox.value == "")
    {
        return false;
    }
    else
    {
        return true;
    }
}
