Requirements
RadControls 2010.3.1317.35version
.NET version 3.5
Visual Studio version 2010
programming language C#
browser support	all browsers supported by RadControls

PROJECT DESCRIPTION
This project demonstrates how to handle ASP.NET Form Validation with the RadAjaxManager when fired from the onkeypress event from a textbox and perform an async postback if the validation succeeded.

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

<telerik:RadCodeBlock runat="server" ID="radCodeBlock">

<script type="text/javascript">

function CheckEnterKey(sender, args) {

var keyCode = args.get_keyCode();

if (keyCode == 13) {

Page_ClientValidate("Search");

if (Page_IsValid) {

var ajaxManager = $find("<%= RadAjaxManager1.ClientID %>");

ajaxManager.ajaxRequestWithTarget('<%= btnSearch.UniqueID %>', '');

}

</script>

</telerik:RadCodeBlock>

</head>

<body>

<form id="form1" runat="server">

<telerik:RadScriptManager runat="server" ID="radScriptMgr">

</telerik:RadScriptManager>

<telerik:RadInputManager ID="RadInputManager1" runat="server">

<telerik:RegExpTextBoxSetting BehaviorID="Setting3" EmptyMessage="Enter Zip Code" ClientEvents-OnKeyPress="CheckEnterKey"

ValidationExpression="\d{5}(-\d{4})?" ErrorMessage="Invalid Zip Code" Validation-IsRequired="true" Validation-ValidationGroup="Search">

<TargetControls>

<telerik:TargetInput ControlID="txtZipCode" />

</TargetControls>

</telerik:RegExpTextBoxSetting>

</telerik:RadInputManager>

<telerik:RadAjaxLoadingPanel Skin="Default" runat="server" ID="pnlLoadingPanel">

</telerik:RadAjaxLoadingPanel>

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="btnSearch">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="pnlSearch" LoadingPanelID="pnlLoadingPanel" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<div style="text-align: center; margin: 0 auto;">

<asp:TextBox ID="txtZipCode" ValidationGroup="Search" runat="server" MaxLength="5" Width="133px" Height="20px"></asp:TextBox>

<telerik:RadButton runat="server" ID="btnSearch" Text="Search" ValidationGroup="Search">

<Icon PrimaryIconCssClass="rbSearch" PrimaryIconLeft="4" PrimaryIconTop="4" />

</telerik:RadButton>

<br /><br />

<asp:Panel ID="pnlSearch" Height="100%" DefaultButton="btnSearch" Width="100%" runat="server">

<asp:Literal ID="litTimeOfSearch" runat="server"></asp:Literal><br /><br /><br /><br />

</asp:Panel>

</div>

</form>

</body>

</html

>



After this you can use some event handling to perform the necessary action postback.




protected void Page_Load(object sender, EventArgs e)
 {
 
     this.btnSearch.Click += new EventHandler(btnSearch_Click);
 
 }
 
 void btnSearch_Click(object sender, EventArgs e)
 {
     Thread.Sleep(2000);
     litTimeOfSearch.Text = string.Format("<b>Last Search Executed at</b>: {0} <br/> <b>Zip code </b> : {1}",  DateTime.Now.ToShortTimeString()
         ,txtZipCode.Text);
 }

Hello skobyjay,

Thank you for sharing your experience with the community.
However I added the provided code, and observed that it does not work in all browsers. That is why I converted the thread to a forum one.
Can you check it out and let me know if I missed something out?

Greetings,
