Hi,

I've create a CallbackPanel and inside i've insert a DataGrid. The CallbackPanel have trigger on DataGrid events.
The Datagrid have a model column with (in edit mode) an HtmlInputFile for uploading image.
When i execute a postback PostedFile is ever a nothing.

I've try to set HtmlInputFile like runat server but nothing.
I've try to set HtmlInputFile like html and find in Form.Files but nothing.
I've try to cancell CallbackPanel and its work correctly.

Thanks

Hi Paroca,

Sorry about the delay. We are looking into it and will get back to you as soon as possible.

Thanks

Hi Samuele,

We looked into the issue. The root of the the problem is a CallbackPanel does NOT postbacks the files for you. It posts back all other form data but not the file. File is a very special input element and it's much more complicated to AJAX-enable it (We have a totally separate control that does just that).

If you are fine with full page reload with file submit (You can still use CallbackPanel for other partial page update, for example, displaying the file input element) You can use the following workaround:
1. Make sure you have enctype="multipart/form-data" on your form element;
2. Avoid letting the DataGrid to submit the change. You can use a regular HTML element to submit the change, for example, a TemplateColumn like this:



This should give you the file. However this does not give you the item index like a regular DataGrid event does. So you will need to have some mechanism to "remember" the last edited item index.

Thanks
