onSubmit event doesn't invoke

[Oleg]

Hello. I've faced with the situation when onChange event doesn't invoke. I have next element:
<input id="txtName" type="text" style="width: 300px;" onchange="txtNameChanged();" id="txtName" maxlength="50" value="Test" name="txtName">

I put the value into this input element using TxtName.Text = "TestValue". Everything is OK. But after the value was inputted the method onchange="txtNameChanged(); should be invoked. It doesn't happens automatically.
I tried to use InvokeEvent(ScriptEventType.OnChange); after TxtName.Text = "TestValue";  but nothing happens. Method onChange still wasn't invoked. Also I tried ActiveBrowser.Actions.InvokeScript("txtNameChanged();"); but it generates me exceptions


Test method Creation threw exception:  ArtOfTest.WebAii.Exceptions.ExecuteCommandException: ExecuteCommand failed!
InError set by the client. Client Error:
System.InvalidOperationException: Javascript call [txtNameChanged();] failed! Please make the function exists and the call is using the correct prototype signature. Javascript error: TypeError: Object expected

Could you please help me with onChange event. How can I type the text into the input and invoke method txtNameChanged(); ????

Hi Oleg,
    my hunch is you need to lose the focus on the input element in order to Fire the onChange event. There are many ways to switch the focus inside a browser instance. The easiest way is probably to record a Tab click. Since you seem to be using the WebAii Framework and not WebUI Test Studio itself, here the code that will let you do that:

ActiveBrowser.Manager.Desktop.KeyBoard.KeyPress(ArtOfTest.WebAii.Win32.KeyBoard.KeysFromString("Tab"), 150, 1);

Try adding this line after TxtName.Text = "TestValue".

Let me know how it goes!

All the best,
