How to select a dynamically created button in Windows form

Hello all,



in my .NET Win Forms application, there is a scenario where a dynamic number of buttons will be created on a form.

I need to perform a click on a certain button.

Have tried the following (see attached screenshot for name mapping):







//attempt to access the record with index 5 and to click the button contained there:

var record = Aliases.TestApp.frmMain.MdiClient.frmOverview.pnlContainer.pnl.WinFormsObject("Record")[5];

var button = record.WinFormsObject("btn")[0];

button.Click();







but this wouldn't work...



What would be the correct approach?



Many thanks for any hints...

    Hello all,



    found out how to access the first level object ("Record") via FindChild() method:





    var PropAray = new Array ("ClrClassName", "Index");

    var ValArray = new Array ("Record", 5)



    var _record = Aliases.TestApp.frmMain.MdiClient.frmOverview.FindChild(PropArray, ValArray);





    Variable record correctly holds the WinForm object "Record" (checked in Inspect window on debugging).

    But now I need to grab the button which is a child of that object and to perform click. So I was under impression that I could just further use the FindChild() method for instantiated and initialized local variable _record, but this does not seem to work (_record.FindMethod() seems not to be possible, also intellisense is not working after typing a dot after _record).



    Is it true, that FindChild() can not be used for local variable? What would be the correct approach to access that button which is child of "Record"?



    Many thanks...

    Well...



    it is indeed possible to use FindChild() method if correct values are set in the property/value arrays ;-).

    It was wrong index value for the button I was searching for - if correct index is set, then everything works fine and button will be found.
