Hi Christian,
1. I was able to see the mentioned problem here, I will discuss it with our tools team and let you know if this is a bug.
2. To determine the current grid in the UpdateUI event, you can have a flag, set it to true in the CurrentCellShowedDropDown event of the main grid and set the flag back to false in the CurrentCellCloseDropDown event. Refer to the code below.
bool flag = false;
// CurrentCellShowedDropDown event of main grid
flag = true;
// CurrentCellCloseDropDown event of main grid
flag = false;
private void OnUpdateUI(object sender, EventArgs e)
{
if(flag)
Console.WriteLine("In DropDown Grid");
else
Console.WriteLine("In Parent Grid");
}
Thanks,

Hi Christian,
Sorry for the delay in getting back to you. You can workaround this problem by adding this event handler and activating the form when the popup occured.
this.popupMenu1.ParentBarItem.Popup += new EventHandler(ParentBarItem_Popup);
private void ParentBarItem_Popup(object sender, EventArgs e)
{
this.Activate();
}
Here is a sample

Hi Rajagopal,
thank you for your sample. It works fine in an SDI-application but not for a MDI-child. Please see the attached sample.

Hi Christian,
Thanks for your update.
Use this code snippet to activate the grid when the popup occured in a popup control.
private void ParentBarItem_Popup(object sender, EventArgs e)
{
this.gridControl1.Focus();
}
Let me know if this helps.
Best Regards,

Hi Haneef,
thank you for your reply, but this sample doesn''t work. When I focus the grid the dropdown grid closes on popup. When I focus the dropdown grid the popup menu does not close. Do you have another idea?

Hi Haneef,
your sample works fine to me, too. In my application I still have this strange behaviour. The popup works fine when the dropdown grid is in edit mode. The grid runs in virtual mode. When I call Focus() the grid queries row height and col width. Perhaps this is the cause!?! I will analyse this behaviour in my application...
Do you have any other ideas?
Regards,
Christian

Hi Christian,
You can handle the CurrentCellActivating event in the DropDownGridCellRenderer.Grid control and set the Focus to the parent grid and child grid. Please find the code snippet below.
//File #[DropDownGridCell.cs]
public class DropDownGridCellRenderer: GridDropDownGridCellRenderer
{
protected override Control CreateInnerControl(out GridControlBase grid)
{
grid = this.grid;
grid.CurrentCellActivating += new GridCurrentCellActivatingEventHandler(grid_CurrentCellActivating);
grid.Dock = DockStyle.Fill;
grid.CausesValidation = false;
return grid;
}
void grid_CurrentCellActivating(object sender, GridCurrentCellActivatingEventArgs e)
{
this.PopupControlContainer.FocusParent();
grid.Focus();
}
}
Let me know if this helps.
Best Regards,
Haneef

Hi Haneef,
thank you for your sample. It works fine except one little problem. The grid in the popup container does not cover the whole area of the conainer. When you click into a grid cell after the popup is shown, the popup is closed correctly. When you click into the area at the bottom of the grid in the popup container, the menu is still not closed.
Best Regards,
Christian

Hi Christian,
I am not able to see this problem happening here, the popup menu gets closed properly when you click into the area at the bottom of the grid in the popup container. Attached is a sample that works fine, please check this. Can you please provide us some relevant screen shots showing the problem.

Hi Rajagopal, hi Haneef
thank you for your sample. Now I found the solution:
* Your last sample works fine because you added this.gridControl1.Focus() to ParentBarItem_Popup(). I didn''t include this because of a strange behaviour in my application (see 7/31/2006 3:26:16 AM )
* The solution of Haneef using the CurrentCellActivating event does not work. The event is only fired when you are in the grid. This is the cause for my last problem (8/3/2006 4:11:13 AM )
* The solution is not using the grid.CurrentCellActivating event but the grid.Click event. It is fired in and out of the grid and focuses the grid.
Thank you very much for your help!!! It would be nice if you fix this behaviour in the next release of the library.
Best Regards,
Christian
