Hi Vera,
Which grid control are you testing? Read the
"Supported VCL and CLX Controls" article - can you find your control on the list of the supported ones? If you cannot, check whether the control is inherited from a control that is on the list. If it is, use the
Object Mapping feature to make TestComplete treat the control as a supported control.
In case this doesn't help, it would be more convenient if you posted here a simple application (not the one you are testing) containing the control. If you cannot do this, please tell us the value of the WndClass property of the control.
