HTMLInputControl mouseclick doesn't work

[Huang]

Hi,
I am using the mouseclick to click a button. However, the mouse cannot move to the top of the button. I also tried the Actions.click, mouse left click, mouse leftdoubleclick, none of them can work. But If I click the button manually, this button can work well and the dialog can be closed successfully. See my code and screenshot. Actually, this issue doesn't happen with mouse click for other buttons.

HtmlFindExpression htmlFindExpress = new HtmlFindExpression("id=popup_panel");
ActiveBrowser.WaitForElement(htmlFindExpress, 5000, false);
Find.ById<HtmlInputButton>("popup_ok").MouseClick();

Hello Huang,

Thank you for contacting us. 

Could you try out this slightly modified code:

HtmlDiv myDiv = ActiveBrowser.Find.ById<HtmlDiv>("id=popup_panel");
HtmlFindExpression htmlFindExpress = new HtmlFindExpression("id=popup_panel");
ActiveBrowser.WaitForElement(htmlFindExpress, 5000, false);
ActiveBrowser.RefreshDomTree();
myDiv.Find.ById<HtmlInputButton>("popup_ok").MouseClick();

Let me know if this helps.

Hi Boyan,

Thanks for your feedback. However, this code cannot resolve my issue. I got an Object reference not set to an instance of an object error when running MouseClick().

I am using the following code as workaround.
ActiveBrowser.Windows.SetFocus()
Find.ById<HTMLInputButton>("popup_ok").MouseClick();

But this workaround is not stable either. The MouseClick will fail sometimes (nearly 1/5 failed).

Hello Huang,

That means that the DOM tree is not fully loaded when you are trying to click on the element.

There are several options you can try.

1. Add a wait statement for the element you are clicking on.

2. Sleep the thread for 2 seconds for example: 

System.Threading.Thread.Sleep(2000);

If the issue persists please please provide us with a copy of your test and if it is possible grant us access to your application so we can reproduce the issue on our end and give you a solution. If it is not possible to grant us access to your application, please take a Fiddler trace and attach it to a support ticket in a zip file. You can capture a Fiddler trace using FiddlerCap.

Hope to hear from you soon.

Hope this helps.
