In this article, I want to explain how to work with custom Upload Dialog Box, if standard methods available in the wrapper throw an error.

Here is an example of such Upload Dialog Box:

As we can see, it appears after we click a custom button “Import 3D Model”. It is a custom Upload Dialog Box, and the following standard methods will not work with it:

expenseClaims.FilesUploadDialog.Upload(@"C:\Users\Anna\Desktop\receipt.jpg");

expenseClaims.FilesUploadDialog.Close();

So, in this case, we need to create our own construction which will validate the file, locate the file input, prepare the file path, upload file and trigger the upload. 

This is my file path that I will use in my test operation later:

string filename = @"C:\Users\Anna\Desktop\piston car.obj";

And here is the operation I’ve created that uploads the above mentioned file and clicks Upload button:

So, it checks if the file exists using File.Exists. If not, a custom exception is thrown to prevent further execution. Then, it uses Selenium's FindElement(By.Id) to identify the file upload input element on the webpage. After that, it prepares the file path, sends the file path to the input element via SendKeys, waits for any background processes, and logs a screenshot for reporting or debugging, and simulates a button click to complete the file upload process with DynamicControl<Button>("Upload").Click().
