I am sorry to hear that you are experiencing this issue.
You can also use the following complete code sample that you can test against a public website:
Manager.Settings.UnexpectedDialogAction = UnexpectedDialogAction.DoNotHandle;
FileUploadDialog x = new FileUploadDialog(ActiveBrowser, @"C:\Test.txt", DialogButton.OPEN);
HtmlInputFile choose = Find.ById<
HtmlInputButton button = Find.ById<
You should be also able to automate radupload dialog file selection as data driven. If you are using the free Telerik Testing Framework and Visual Studio, you will need to follow their directions for creating a data driven test
. If you are using Test Studio you need first to Bind the test to an external data source
and then write the code in a coded step
// You can reference the column by index
string fileLocation = (string)Data;
// Or by name
string fileLocation2 = (string)Data["Files"];
If you need additional assistance please do not hesitate to contact us and give us more details about your testing scenario.
