Hello,


One suggestion is saving the client object of RadUpload in a client global variable. You can perform this in client side event - OnClientLoad() of RadUpload, thus you will be able to access the control in any of the client custom functions.

And, have you tried the approach shown in documentation in order to check the file size on client side?

Checking File Size on the Client
This not active. I try this. Please give me a better example.
Can you say more about OnClientLoad()?
Thanks you for your reply,

Hello Long,

I was able to reproduce this issue in Chrome, actually the problem is that OnClientProgressUpdating event is not fired at all. We'll research this and will write you back. Thank you for your understanding.

Hi Long,

I'm sorry for the delayed reply. Actually this is a known limitation of RadProgressArea in the webkit browsers as described here .

Hello Amjad,

RadAsyncUpload can automatically validate files using the AllowedFilesExtensions properties and the MaxFileSize property. RadAsyncUpload provides client-side event called OnClientValidationFailed. It is fired when the selected file has invalid extension or its size is higher than the MaxFileSize property.

Check out the following demo for more on this.
Upload / Validation.

Thanks,
Shinu.

Hello Amjad,

Check out the following help document to achieve your scenario.

Hello Amjad,

You can't validate the file size without the use of the RadProgressManager/RadProgressArea because they are the controls that know the file size, the RadUpload cannot determine a file's size on the client.

 

I hope that explains why you need the RadProgessManager/RadProgressArea to find out an uploaded file's size.

Hello Amjad,

Cori is correct into the last post(21-Jun-2011). RadUpload is using a standard input type="file" control and it is not possible to chec the file size client-side due to browser limitation.
