I'm having problems with UltraDropDowns (used in grids) since my recent upgrade from 8.1 to 8.2. I'll try to outline these issues:1) UltraDropDown (used on a grid) fields do not auto complete. When I type an "A" into the UltraDropDown, it does not suggest something starting with A to me.2) When I type in an existing value exactly (which is in the dropdown list), it does not recognise it. That is, in the grid.BeforeCellUpdate event, the dropDown.SelectedRow property is null.I have done a little searching of the forums into this, and have found some reference to an AutoCompleteMode that was added (although I'm not sure if this was added in 8.1 or 8.2). I cant find such a property for the UltrarDropDown, but I can for the UltraGrid columns. They appear to be set to "None" for every column. I have attempted to change this to "Default" for one column. After saving it, and re-opening the form, it is back to "None". It seems to be resetting itself back after I save it.
Whats going on here? Why is auto complete not working, why is it not accepting typed in values? What has changed?
I think the issue of the AutoCompleteMode being set to None is a known bug. It may already be fixed in the latest Hot Fix, so you should download it and try it out. If that does not help, you should Submit an incident to Infragistics Developer Support.
Thanks. I already have the latest hotfix, so I logged an incident with support.
The reply I got was less then encouraging:----SUPPORT REPLY START ----
Thank you for submitting your query with Infragistics. I would like to let you know that AutoCompleteMode does not work in reference to UltraDropDown control. Please go through the following online help article that explains "AutoCompleteMode Property":<http://help.infragistics.com/Help/NetAdvantage/NET/2008.2/CLR2.0/html/Infragistics2.Win.UltraWinGrid.v8.2~Infragistics.Win.UltraWinGrid.UltraGridColumn~AutoCompleteMode.html>
I would suggest you to use ultracombo control, please have a look upon the following online help article:<http://help.infragistics.com/Help/NetAdvantage/NET/2008.2/CLR2.0/html/Infragistics2.Win.UltraWinGrid.v8.2~Infragistics.Win.UltraWinGrid.UltraCombo~AutoCompleteMode.html>
Hope this helps you. Thank you for your patience in this matter.
Considering that when I started using Infragistics controls (v7.3) I was told by by an infragistics employee on these forums that I should be using UltraDropDowns on grids, not ultraCombo's, this is a very dissapointing answer.
Whats going on here? Is the support guy right? Or does he/she not know what they are talking about?
Mike,
I must interject as I am attempting to accomplish the same thing as the original poster. I am using an UltraDropDown, and want it to drop down automatically and suggest as I type in the grid cell. Currently I have not found a solution, The first link provided in fweeee's post from support (below), is for the AutoCompleteMode property of the UltraGridColumn:
<http://help.infragistics.com/Help/NetAdvantage/NET/2008.2/CLR2.0/html/Infragistics2.Win.UltraWinGrid.v8.2~Infragistics.Win.UltraWinGrid.UltraCombo~AutoCompleteMode.html>
The second to last paragraph states:
Setting the ValueList property can in certain circumstances interfere with the suggest mode functionality. If, for example, the property is set to reference an UltraDropDown control, suggest mode is disabled. Suggest mode support for multi-column lists is extended through the UltraCombo control; this can be enabled by assigning a reference to the UltraCombo control to the column's EditorControl property (which enables UltraCombo to serve an UltraGridComboEditor instance via its IProvidesEmbeddableEditor implementation), then setting the AutoCompleteMode property on either the column or the control.
So according to the documentation this does not work when using an UltraDropDown. I have attempted it with no success. Do you have any other suggestions in getting this to work correctly. Do we need to submit an incident with support to try to get development to add this functionality to UltraDropDown?
ThanksLonnie
Hi Lonnie,
lthibx said:So according to the documentation this does not work when using an UltraDropDown. I have attempted it with no success.
That is correct. This will not work with UltraDropDown.
lthibx said:Do you have any other suggestions in getting this to work correctly.
The solution is very simple and is explained quite clearly in the paragraph you posted here. Use an UltraCombo as the EditorControl instead of using an UltraDropDown as the ValueList for the column.

Submitting an incident will not do any good. This is not a bug. The reason it does not work with UltraDropDown is that part of the suggest functionality must be handled by the editor in the grid cell. So in order for this to function, you must use an EditorControl so that it can integrate the functionality between the editor in the cell and the dropdown list - as stated in the paragraph you posted here.
I have for the past day been trying without success to get the suggest functionality to work inside grid cells as suggested in the paragraph.
I am using databound UltraCombo, and I have assigned it to the EditorControl of the grid cell. AutoCompleteMode has been set to all possible values and both in the cell and in the UltraCombo itself. All I get, at best, is append functionality, not the desired suggest dito.
This behaviour with NetAdvantage for .NET 2009.1
Any suggestions?
Best regards,
Goran
Hi Goran,
I tested this out and it seems to work okay if I set the AutoCompleteMode on both the UltraCombo and the grid column to the same value. I'm attaching a sample here that works.
I'm not sure why you should have to set both. There may be some reason for that, but on the other hand it may be a bug. I am going to look into that aspect of it.
Looks like I was right, you should not have to set the AutoComplete mode on both the grid column and the combo. So that was a bug and it will be fixed in the next service release. But for now, setting the property on both works.
Hi,
One more thing. If i cannot use MultiLine and type ahead together then how do i wrap the cell text if it is greater than the width of cell. I do need the type ahead functionality and want to wrap my cell text without it getting truncated after it extends cell width.

I'm sorry, but there is no way that I know of to get these two features to work together properly. The TextBox control fires events differently when Multiline, and there's no way for the control to detect this. So these two features are not supported together.
I have certain items in the list which have there description in square brackets eg: DEL[New Delhi] in such a scenerio i have to display code 'DEL' in first line and '[New Delhi]' in the newLine
There is no way to do this and no known workaround. Why do you need CellMultiline set to true when all of your values are a single word, anyway?
the functionality i am looking for is:
Example:
Assume that my datasource contains the following names: Abc, Abcd, Bangalore, Bengule, Delhi, Dear.
In UltraGrid column i have set CellMultiLine to true.
But when i set CellMultiLine to false
Can you suggest some work around through which Correct Type Ahead and CellMultiLine set to true can be achieved.
