Hi Gokul,

The information that you provided is not enough for us to identify the reason for the problem that you experience. Could you please post the RadGrid's declaration, the ajax settings and the javascript functions. Once we have a better view over your exact setup we will do our best to help.

Additionally you could check out the following online examples:

All the best,

Hi,
    this is my RadGrid
   

<telerik:RadGrid ID="gridTest" AllowMultiRowSelection="true" AllowSorting="true"

AutoGenerateColumns="false" AllowPaging="true" runat="server" Skin="Outlook"

PageSize="5" AllowFilteringByColumn="true"

onneeddatasource="gridTest_NeedDataSource"

onpageindexchanged="gridTest_PageIndexChanged"

onprerender="gridTest_PreRender">

<PagerStyle Mode="NextPrev" />

<MasterTableView CommandItemDisplay="Top">

<Columns>

<telerik:GridImageColumn AllowFiltering="false" ImageUrl="images/user.png">

<ItemStyle Width="20px" Height="10px" HorizontalAlign="Center" />

</telerik:GridImageColumn>

<telerik:GridClientSelectColumn>

<HeaderStyle Width="20px" Height="10px" HorizontalAlign="Center" />

<ItemStyle Width="20px" Height="10px" HorizontalAlign="Center" />

</telerik:GridClientSelectColumn>

<telerik:GridBoundColumn HeaderText="Name" AllowFiltering="true" DataField="Name"

AutoPostBackOnFilter="true" CurrentFilterFunction="Contains" FilterImageUrl="../images/view.png"

UniqueName="Name">

<HeaderStyle Width="125px" Height="10px" HorizontalAlign="Center" />

<ItemStyle Width="125px" Height="10px" HorizontalAlign="Center" />

</telerik:GridBoundColumn>

</Columns>

<CommandItemSettings ShowExportToCsvButton="true" ShowAddNewRecordButton="false" />

</MasterTableView>

<ExportSettings ExportOnlyData="true" FileName="gridTest" IgnorePaging="true"

OpenInNewWindow="true">

</ExportSettings>

<ClientSettings>

<Selecting AllowRowSelect="true" />

<ClientEvents OnGridCreated="GridCreated" OnRowSelected="RowSelected" OnRowDeselected="RowDeselected" ></ClientEvents>

</ClientSettings>

<FooterStyle Height="30px" />

<AlternatingItemStyle BackColor="LightSteelBlue" />

<FilterItemStyle HorizontalAlign="Center" Height="10px" />

</telerik:RadGrid>

and this is my AjaxManager content in the page

<telerik:RadAjaxManager ID="RadAjaxManager2" runat="server">

<ClientEvents OnRequestStart="onRequestStart" />

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="gridTest">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="gridTest" LoadingPanelID="LoadPanel" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager ID="RadAjaxManager2" runat="server">

and this is my script OnRequestStart

function onRequestStart(sender, args)

{

if (args.get_eventTarget().indexOf("ExportToCsvButton") >= 0)

{

args.set_enableAjax(false);

}

}

Thanks in advance

Hi Radoslav,
            The difference between the example code and my code is, I am using some update panels in the page.
Actually I am trying to convert my web controls to Rad controls. this is my issue.  I am not using Rad script manger just a normal script manager  but it's not the problem I think . The web.config files had a lot of difference because my code is basically a Asp.net web application not a Telerik web application.
