    You need to cancel the postback, let the spellcheck work and initiate the postback again when it finishes. Otherwise, the postback will dispose the spell because it works on the client.

    There are various ways to do this and perhaps this KB article will help you with one approach: http://www.telerik.com/support/kb/aspnet-ajax/spell/details/invoke-separate-spell-check-for-each-textbox-and-submit-the-form-on-success.

    Another suggestion is to use the client-side API and events of the control:

    For your convenience I prepared a small example here:

    <asp:TextBox ID="Textbox1" runat="server" Text="miztakes" />
    <telerik:RadSpell ID="RadSpell1" runat="server" ControlToCheck="Textbox1" ButtonType="None" OnClientCheckFinished="invokePostback" />
    <asp:Button ID="Button1" Text="check and submit" OnClientClick="invokeSpellCheck(this); return false;" OnClick="Button1_Click" runat="server" />
    <script type="text/javascript">
        function invokeSpellCheck(btn) {
            var spell = $find("<%=RadSpell1.ClientID %>");
            spell.__customButtonReference = btn;
        function invokePostback(sender, args) {
            if (sender.__customButtonReference) {
                __doPostBack(sender.__customButtonReference.getAttribute("name"), "");

    Hi Karthik,

    Please try to attach the OnClientDialogClosed event of RadSpell and try to call the OnClick event of RadButton from OnClientDialogClosed event as follows and also set the AutoPostBack property of RadButton as false.

    function finishCheck(sender, args) {
        button = $find("<%=rbtnSpellCheck.ClientID%>");
        __doPostBack(button.get_id(), "OnClick");
