Hi Singh, You can achieve your requirement to cancel closing the dropdown while pressing ESC key on the ComboBox cell can be achieved by handling the CurrentCellShowingDropDown, CurrentCellCloseDropDown and CurrentCellKeyDown events as shown below.  Code example :

this.gridControl1.CurrentCellKeyDown += GridControl1_CurrentCellKeyDown; 
this.gridControl1.CurrentCellShowingDropDown += GridControl1_CurrentCellShowingDropDown; 
this.gridControl1.CurrentCellCloseDropDown += GridControl1_CurrentCellCloseDropDown; 
 
private void GridControl1_CurrentCellCloseDropDown(object sender, Syncfusion.Windows.Forms.PopupClosedEventArgs e) 
{ 
    isDropDownOpened = false; 
} 
 
bool isDropDownOpened = false; 
private void GridControl1_CurrentCellShowingDropDown(object sender, GridCurrentCellShowingDropDownEventArgs e) 
{ 
    isDropDownOpened = true; 
     
} 
 
private void GridControl1_CurrentCellKeyDown(object sender, KeyEventArgs e) 
{ 
    var grid = (sender as GridControl); 
 
    if (grid.Model[grid.CurrentCell.RowIndex, grid.CurrentCell.ColIndex].CellType == GridCellTypeName.ComboBox) 
    { 
        e.Handled = isDropDownOpened; 
    }
