Hi

Try putting this code in OnAction()

if (wdContext.currentTestElement().getValue() == null){
		wdComponentAPI.getMessageManager().reportException("Invalid File  ",true);
}

Hi

Create an value attribute say Ctx_va_FilePath of type 'binary' in the context of the view.

Set the filepath property of the fileupload ui element to this value.

On pressing of upload button, simply check if the filepath is null or not

using the code

if (wdContext.currentContextElement().getCtx_va_FilePath() != null)

{

//code

}

If filepath is not null, carry on with the execution and if filepath is null , advise the user to select a file first.

Hi,

let assume that Data is context attribute of type binary, and it is bind to a data propety of the fileupload ui element then use the following code

if(wdContext.currentContextElement().getData()==null){

// write ur code here

}

hi,

Check whether file resource is null if it is null then display the message of no file

IPrivateFileUploadView.IContextElement element =
      wdContext.currentContextElement();

    //	if a file in the FileUpload field exists
if (element.getFileResource() != null) 
{
.......
}
else
{
    message of no file
}

Hi

Well can you give a print of the exception.

And also check if you have bound the property filename to a context attribute of type string.
