PostbackTrigger control in another usercontrol (LOD)

[Larkin]

I have a RadAsyncUpload control in one usercontrol, loaded dynamically (wizard-style using RadTabStrip and RadMultiPage). I don't want to trigger the FileUploaded event until the Save button is clicked in the last panel of the wizard. Is this scenario supported? There will be a button in each PageView that will share the same ID--not a problem given that they are in different naming containers, of course, but perhaps a problem for RadAsyncUpload? How does it resolve the Control IDs contained in the PostbackTriggers property?

Thanks in advance for your help,

Larkin

Hi Larkin,

If I understand correctly, you want to have the AsyncUpload control in one PageView, and a Button, which triggers the UploadPostback, in another PageView. That's not a problem and RadAsyncUpload works fine in this scenario. I've attached a sample page showing this functionality. 
If it doesn't work for you, or you use a different approach, please provide a sample page showing exactly what you want to implement.

Best wishes,

That answers my question--thanks!

I have a question similar for this, that the example does not address. The example address two controls in the same naming containers. Is it possible to reference a post back as a control in a different user control?

E.g. Control A has control repeating block for upload and data (control b). Below the repeating block is a button to upload all data (btnUploadAll).

Control B has the RadAsyncUpload and a set of metadata for the document. Is it possible to wire the postback trigger to the parents (btnUpLoadAll) button?

Hi Greg,

 
The PostBackTriggers property can be used if you know the exact  ID of the button the will be assigned to it and will work properly if RadAsyncUpload  is rendered on the page. 

Hope this will be helpful. If in your case this is somehow not working please elaborate a little bit so we could be more help.

All the best,
