Hi Andrew,
Greetings from Syncfusion support.
By default, When we pressing the ‘Tab’ key we are traversing from one cell to the next cell. So while pressing the "Tab" key, we focused only on Grid cells(it won't focus directly on the inside component of Grid cells). This is the default behavior of the Grid.
Could you please confirm the following information before proceeding your requirement.
- You have mentioned 3rd column as DropDownList. So, you have rendered DropDownList by using ‘ColumnTemplate’ feature or Enable ‘DropDownList’ edit in the Grid columns.
- Share the sample code example of your Grid rendering.
- Do you want to open the DropDownList popup when pressing ‘’tab” key from another cell.
Regards,
Manivel
