RadAsyncUpload call with buttons in RadGrid

[Raulis]

I have a RadAsyncUpload somewhere on a page and a RadGrid in the same page.The RadGrid has a column for every row that is a LinkButton which executes a grid ItemCommand. The ItemCommand fetches the ID associated to the row and stores it in a session variable. I want the item command to also then bring up the RadAsyncUpload window so the user could select files.

 

The way I tried to achieve this so far is by calling a javascript function which finds the RadAsyncUpload control and performs a button click. This does not happen after postback, however. 

 

It is crucial to me that each file I upload is associated with a row ID. Is there a way I can achieve this scenario or am I limited by the RadAsyncUpload controls functionality?

Furthermore, the RadGrid does not have an Insert/Edit mode and I will not be implementing these. So the demos on the Telerik website do not work for my scenario.

Hello Raulis,

The AsyncUpload allows you to select a file and upload it. It does not have built-in functionality related to associating a file with something. If your scenario does not involve using the Grid's InsertCommand/UpdateCommand events as shown in this demo, you could consider implementing a Custom Handler. You can review the following demo, which demonstrates how a custom handler can be used to save an image in a database along with additional information, which in the example is the hard-coded UserID, but in your case could be the ID you keep in the session.
