CXTPReportRecordItem question

Good day. Here is my question:
I have a Grid with different type of controls inside. Is it possible to change CheckBox items to RadioButtons??
I can't find ModifyStyle() method in CXTPReportRecordItem.
I try to do somthing like this

................
CXTPReportInplaceButtons * pInplBut = &pNewItem->GetEditOptions(NULL)->arrInplaceButtons;
pInplBut->GetAt(0)->ModifyStyle(BS_AUTOCHECKBOX , BS_AUTORADIOBUTTON);
...............
But seems to me there is no my checkbox item in this array.

And second question:
I add CXTPReportRecordItemText into my grid,  then I add some constants into it, add inplace combo button. All works fine. When I press to combo button and want to select some constant selection in drop list stay at it position. How to make this selection move for the mouse cursor on mouse moving?

Thank for help.
