How to increase size of drop-down area for GridControl cell?

[Alexander S]

I have a GridControl with cells which are using "ComboBox" style. I have a lot of items in my drop down list and drop down area is too short to show them all. So user has to scroll down to choose some items. Is there a way to increase height of the expanded area and show all items without scroll bar? 

Look an image to see what I mean -

Hi Alexander,

Thank you for using Syncfusion Products.

We have used the property DropDownRows in CurrentCellShowingDropDown event in order to change the size of the dropdown area.

By using the DropDownRows property we can set number of visible items for combo boxes in particular row.

Please refer to the below UG link,
