use server side validations for server side and use code for textbox.
server button's onClientClick="CheckEmptyText()"
function CheckEmptyText() {
if (document.getElementById('textbox1').value=="")
{
window.alert('please fill the textbox');
}
}

hi,
u can call the function at serverside control like as follows:
<asp:textbox id="txtname" onchange="return javascript:checkall(e);" />
u have to write the external or internal .js file:
CommonFunctions.js
function checkall()
{
if(document.getElementById("txtname").value=='')
{
alert('enter name.');
document.getElementById("txtname").focus();
return false;
}
blablablablablablablablablablablabla-----------
else
{
return true;
}
}
ok...

also u can add attribute to button on page load
e.g
button.attributes.add("OnClick","javascript:return functionname();")

Suppose we have a button.
first add attributes for the button in the page load,
btnSubmit.Attributes.Add("onmouseover", "ChangeColor(this);");
Then write the javascript method ChangeColor,
<script type="text/javascript">
function ChangeColor(pointer)
{
pointer.style.background="Silver";
}
</script>
like this we can add any javascript method to an event.if you want to add validation do like this and write javascript method accordingly.

Hi
There are two methods available to register a script in .NET environment. They are RegisterStartupScript and RegisterClientScriptBlock
------------
<HTML>
<HEAD>
<title>WebForm1</title>
<script language="javascript">
function pop_window()
{
var confirmWin = null;
confirmWin = window.open('PopUpWindow.aspx','anycontent',
'width=455,height=435,status');
}
</script>
</HEAD>
<body>
<form name="Form1" method="post" action="WebForm1.aspx"
id="Form1">
<input type="button" onClick="pop_window()" value="Open Window">
</form>
</body>
</HTML>
-------------
private void Button1_Click(object sender, System.EventArgs e)
{
string PopUpWindowPage = "PopUpWindow.aspx";
//Script for popup window
string Script = "";
Script += "\n<script language=JavaScript id='PopupWindow'>\n";
Script += "var confirmWin = null; \n";
Script += "confirmWin = window.open('"+PopUpWindowPage+"',
'anycontent',
'width=455,height=435,
status'); \n";
Script += "if((confirmWin != null) && (confirmWin.opener==null))
{ \n";
Script += " confirmWin.opener = self; \n";
Script += "}\n";
Script += "</script>";
//Script for displaying popup window information in main window
string ParentLoadScript = "";
ParentLoadScript += "\n<script language=JavaScript
id='ParentLoad'>\n";
ParentLoadScript += "function addOption(strValue){ \n";
ParentLoadScript += "var objForm = document.forms['Form1'];\n";
ParentLoadScript += "var objFormField =
objForm.elements['TextBox1'];\n";
//ParentLoadScript +="alert(objFormField);\n";
ParentLoadScript += " if (objFormField != null)
objFormField.value = (strValue); }\n";
ParentLoadScript += "</script>";
//Check whether they are already registered
if(!this.IsStartupScriptRegistered("PopupWindow"))
{
//Register the script
this.RegisterStartupScript("PopupWindow",Script);
}
//Check whether they are already registered
if(!this.IsStartupScriptRegistered("ParentLoad"))
{
//Register the script
this.RegisterStartupScript("ParentLoad",ParentLoadScript);
}
--------------------------
refer code.

1. Add the following lines inside the <head> tag
<script type="text/javascript" language="javascript">
function JSValidation()
{
var txtUser = document.getElementById('txtUserName');
var txtPass = document.getElementById('txtPassword');
var lblMiss = document.getElementById('lblMissing');
if(txtUser.value == "")
{
lblMiss.innerHTML = "Either UserName or Password or Both are not given";
return false;
}
else if(txtPass.value == "")
{
lblMiss.innerHTML = "Either UserName or Password or Both are not given";
return false;
}
else
{
lblMiss.innerHTML = "";
return true;
}
}
</script>
2. Add the following line inside the Page_Load function
this.btnSignIn.Attributes.Add("OnClick", "return JSValidation();");
I attach the full project for this functionality you can also check that one.
If you have any further confusion than do inform me.
