Prevent RepositoryItemSearchLookUpEdit when Popup is Open When CloseUpKey.Key is pressed - winforms

Question

I use a RepositoryItemSearchLookUpEdit. its CloseUpKey property is set to space
result.CloseUpKey = new DevExpress.Utils.KeyShortcut(System.Windows.Forms.Keys.Space);
I want to use this shortcut only for open popup and not for closing popup.
How can I achieve this?
UPDATE------------------------
First I create an RepositoryItemSearchLookUpEdit object
var result = new RepositoryItemSearchLookUpEdit();
result.CloseUpKey = new DevExpress.Utils.KeyShortcut(System.Windows.Forms.Keys.Space);
result.KeyDown += repositoryItemLookUpEdit_KeyDown;
result.CloseUp += repositoryItemLookUpEdit_CloseUp;
result.QueryCloseUp += repositoryItemLookUpEdit_QueryCloseUp;
private void repositoryItemLookUpEdit_QueryCloseUp(object sender, System.ComponentModel.CancelEventArgs e)
{
var edit = sender as SearchLookUpEdit;
KeyEventArgs k = new KeyEventArgs(edit.Properties.CloseUpKey.Key);
AttachKeyPressEvent(k);
if (k.KeyCode == edit.Properties.CloseUpKey.Key)
e.Cancel = true;
}
And pass it to a grid column:
grdListView.Columns["yyy"].ColumnEdit = result
How can I achieve that with these events, without creating a descendant SearchLookUpEdit

UPDATED:
The problem is that CloseUp event (where you could get the necessary info about the closeup key) occurs after the QueryCloseUp event (where you could precent the closing up event). Also the KeyPress, KeyDown and KeyUp events seem also NOT to occur when the QueryCloseUp occurs, as a result they couldn't be overridden. So I tried this, I created a custom KeyEventHandler and triggered him during QueryCloseUp event in order to get the necessary info of what key was pressed and cancel the event if the close key event was the one. Here is my codeTry it to see if it suits you
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
//Here you can add your grid control as you have created
DataTable dt = new DataTable();
dt.Columns.Add("ID"); //use your own names and types
gridControl1.DataSource = dt;
var result = new RepositoryItemSearchLookUpEdit();
result.CloseUpKey = new DevExpress.Utils.KeyShortcut(System.Windows.Forms.Keys.Space);
result.QueryCloseUp += new CancelEventHandler(repositoryItemLookUpEdit_QueryCloseUp);
((gridControl1.MainView as GridView).Columns["ID"] as GridColumn).ColumnEdit = result;
}
private static readonly object myQueryCloseUp = new object();
public event KeyEventHandler MyQueryCloseUp
{
add { Events.AddHandler(myQueryCloseUp, value); }
remove { Events.RemoveHandler(myQueryCloseUp, value); }
}
protected virtual void AttachKeyPressEvent(KeyEventArgs e)
{
KeyEventHandler handler = (KeyEventHandler)Events[myQueryCloseUp];
if (handler != null)
handler(this, e);
}
//Here you add your own Handler implementation
public void repositoryItemLookUpEdit_QueryCloseUp(object sender, CancelEventArgs e)
{
KeyEventArgs k = new KeyEventArgs((sender as SearchLookUpEdit).Properties.CloseUpKey.Key);
AttachKeyPressEvent(k);
if (k.KeyCode == (sender as SearchLookUpEdit).Properties.CloseUpKey.Key)
e.Cancel = true;
}
}
