I have a grid with grouping and scrolling enabled.
On export to pdf the grid is not exported in a new page. instead it loads the data in the grid.
I have the export functionality working as desired on other pages in the app. It gives a prompt to save or open the export. But with the grid I am referring to it does not prompt, just loads the export data into the grid.

I am using the latest Telerik Controls. Pasted below is my grid code:


<telerik:RadGrid ID="RadGridCalendar" runat="server" GridLines="None" AllowPaging="true" PageSize="20"
                            AllowFilteringByColumn="true" Width="980px" ShowHeader="true" OnColumnCreated="RadGridCalendar_ColumnCreated"

Hello,

Please make sure that the control that initiates the export is NOT ajaxified.
Export from ajaxified grid

I hope this helps.

I removed the RadGrid from RAdAJAXManager but it still behaves the same.
I have other grids in the app that are used in a similar manner but the export works just fine on them.

Hello,

I examined the provided code but it doesn't indicate whether the exporting button is ajaxified or not.
I recommend that you perform a global search to find all AJAX controls (UpdatePanel, RadAjaxManager, RadAjaxPanel)

You can temporary disable AJAX (for testing purposes) if you set EnableAJAX="false" to RadAjaxPanel or RadAjaxManager (the manager, not the proxy).
<telerik:RadAjaxManager
   ID="RadAjaxManager1"
   runat="server"
   EnableAJAX="false">
...

If the problem still persists, please attach your project to a regular support ticket and I will debug it on my end.

Regards,
Daniel

Hi You can do this simply by applying event -  OnClientClick="aspnetForm.target ='_blank';" 

 <asp:Button ID="exportPDF" runat="server" target="blank" Text="Export PDF" OnClientClick="aspnetForm.target ='_blank';" CssClass="btn btn-info" />

Two notes on @prateek's comment.

1. Use your form's ID in the OnClientClick value (e.g., "form1.target='_blank';" if your form has the ID form1).

2. In my scenario I have two buttons: one export to PDF and one export to Excel. I set the OnClientClick value only to the PDF button. If I load the page and click "Export to PDF" and then "Export to Excel", both will open in a new browser tab. If I load the page and click on "Export to Excel" first, it does not open a new browser tab. Go figure.
