Ajaxified Export to CSV button (Using The response obj causes error in ajaxpanel)

I have an export to csv button that worked untill I Ajaxified all controls on this page with an ajaxpanel.

I get a javascript error as follows:
[Exception... "'Sys.WebForms.PageRequestManagerParserErrorException: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near '"Source","Source Cre'.'

My code resembles the one below:

Thanx for the help.

<asp:LinkButton ID="ExportLinkButton" runat="server" CssClass="export linkText menu left" Text="Export CSV"
OnClick="export_Clicked" ToolTip="Export to csv" ></asp:LinkButton>

protected void export_Clicked(object sender, EventArgs e)
        {
                   string fname= "path/FileName.csv";
                   string path = MapPath(fname);
                    string name = Path.GetFileName(path);
                    string ext = Path.GetExtension(path);
                    string type = "text/csv";
                    Response.ContentType = type;
                    Response.AppendHeader("content-disposition", "attachment; filename=" + name);
                    Response.WriteFile(path);
                    Response.End();

RadAjaxManagerProxy refreshes the whole page when a dropdownlist is added

Hi, I have a strange behavior when I'm using the Dropdownlist using RadAjaxManagerProxy. The whole page refreshes instead of just the desired controls.Please see the following snippet of code and suggest what am I doing wrong.

<telerik:RadScriptManager ID="ScriptManager1" runat="server" EnableTheming="True">

</telerik:RadScriptManager>

<telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">

<telerik:AjaxSetting AjaxControlID="list1">

<telerik:AjaxUpdatedControl ControlID="Label1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

<asp:Panel ID="Panel1" runat="server">

<asp:DropDownList ID="list1" runat="server" AutoPostBack="true" OnSelectedIndexChanged="list1_SelectedIndexChanged">

<asp:ListItem Text="ENG" Value="0"></asp:ListItem>

<asp:ListItem Text="AUS" Value="1"></asp:ListItem>

<asp:ListItem Text="SA" Value="2"></asp:ListItem>

</asp:DropDownList>

<asp:Label ID="Label1" runat="server" Text="CurrentDate"></asp:Label>

</asp:Panel>

On the Code behind:

public partial class _Default : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

if (Page.IsPostBack)

{

GetLatestDate();

}

public void GetLatestDate()

{

Label1.Text =

DateTime.Now.ToString();

}

protected void list1_SelectedIndexChanged(object sender, EventArgs e)

{

GetLatestDate();

}
}

Telerik.WebControls.GridInsertionObject error with property is an user class

I found some information here http://www.telerik.com/community/forums/aspnet-ajax/grid/telerik-webcontrols-gridinsertionobject-error.aspx and here http://www.telerik.com/help/aspnet/grid/grderrormessages.html but they cannot help because my property is a class, not a primitive type.

My error message: 'Telerik.Web.UI.GridInsertionObject' does not contain a property with the name 'Address'.

Is there anyway to bind a data class in insert mode?

File Upload filter images(gif,jpeg,png,...)

Hi

In my application using radgrid i m uploading or editing documents with Fileupload

control.

Mean while i have a combobox with items as "GENERAL,Accounts and sponsorlogo".

suppose if i select General or accounts ,am able to upload any time of contents.

but if i select sposorlogo. i should be able to upload only images (like GIF,JPEG,PNG,BITMAP,..)

this should be acheived in opendialog box itself .and i don't want to acheive this by code like

cases with extension in code behind.

(For quick understand if u try to convert RM to MP3 songs through RM to MP3 converter.

While uploading if filters and lists only files with extension .RM not any other extension.)
