I am facing an issue of object identification with the dropdown element of DHTML grid. When I tried to recognize these different dropdown objects, QTP identifies only one object for all the dropdowns. Hence, selection of different data from different dropdowns list is an issue. To overcome this problem, i have used Descriptive Programming technique by creating different object descriptions which have all the other properties same but differ only in one property i.e. ‘X’ location of the element on the screen. Hence, i have created distinct object descriptions that would allow us to select values in different dropdowns. The code is given below. But still I am unable to identify distinct dropdown objects. ‘Object Description for Dropdown Cell Status Set objCellStatus = Description.Create objCellStatus("micclass").value = "WebList" objCellStatus("name").value = "select" objCellStatus("x").value = 219 ------ ‘X’ Axis value for cell status drop down ‘Object Description for Dropdown Sub Segment Set objSubSegment = Description.Create objSubSegment("micclass").value = "WebList" objSubSegment("name").value = "select" objSubSegment("x").value = "319" ------ ‘X’ Axis value for sub segment drop down Please help... This is specific to DTML grid(Drop down object)
