You can use a RequiredFieldValidator control for that.
<asp:RequiredFieldValidator id="rqField1"
ControlToValidate = "ID of input control to validate"
InitialValue = ""
ErrorMessage = "message to display in ValidationSummary control"
Text = "message to display in control"
runat="server" />
See
jQuery based solution
$(function(){
$("#txt1").bind("blur", function(){
var val = $.trim($(this).val());
if ( val === "" )
{
$("#spnError").show();
}
else
{
$("#spnError").hide();
}
});
});
<span id="spnError" style="display: none">Please enter valid input</span>
<input type="text" id="txt1" />
<input type="text" id="txt2" />
You can attach onblur event to first textbox in Page_Load
textbox1.Attributes.Add("onblur","validate()");
Implement validate method in your aspx file as
<script type="text/javascript">
function validate(){
//Do validation , show messages etc
}
</script>
You can also try something like
<html>
<head>
<script type="text/javascript">
function Test(txt, label)
{
if (txt.value == "")
label.innerHTML = "Wrong Value";
}
</script>
</head>
<body>
<input type="text" id="txt1" onblur="Test(this, lbl1);"/>
<label id="lbl1" for="txt1">SomeVal</label>
</body>
