RADGrid client binding download link

[Neo]

Hello Telerik Team,

I am having RADgrid in on of the module of my application. In there we have linkbutton by which i have to download document.

So before i implemented client binding it was working on server side by Item command event. but as i have implemented client side binding i m not getting command argument which are given on client side by javascript.

so below is the code running on server side,
 

MemoryStream stream = TheWay.GetDocument("*", Number, "*", "*") as MemoryStream;<br>
 Response.ContentType = contentType ?? "text/plain";<br>
                                Response.AddHeader("Content-Disposition", "attachment;filename=" + attachment.FileName);<br>
                                byte[] buffer = stream.ToArray();<br>
                                stream.Read(buffer, 0, Convert.ToInt32(stream.Length));<br>
                                Response.ClearContent();<br>
                                Response.BinaryWrite(buffer);                                <br>
                                Response.End();

Now, Can we do this thing in javascript or by web service? I m not sure abt this one.

Hi Neo,

In order to achieve your scenario, you should attach a client-side event method to the onclick event of the link button and in the event handler use RadAjaxManager's client-side ajaxRequest() method to make a trip to the server and execute the code needed. You can find more information on that at the following help topic:

Hope it helps.

Hello Tsvetoslav,

Thanks for the reply.

I can make web service call from javascript and execute the logic to get document from server 
but i m not sure how i can transfer that on client side in javascript and export that file.

Hello Neo,

I am not sure I have correctly understood your scenario. In case that you want to bind the grid to a given file and then export, you are hitting an unsupported scenario.

If, however, by exporting you mean just to be able to download the file when clicking upon the link, here are some guidelines on how to achieve this:
