It is an UltraDropDown, which I am programatically assigning to the ValueList, like so:

ultraGrid.DisplayLayout.Bands[0].Columns["ColumnName"].ValueList = Brandmngt.CreateDropDown(jobItemGridValidationMngt.DropDownSelectedmngt, null, true, true);

The Brandmngt class is one that I use on numerous forms, where I need to generate this dropdown. It reads data from the database, formats the dropdown, add required events, etc.

Yes - only for the string columns, and only if they are currently null.

I dont understand the bit about translating DataValues into DisplayValues.

I have tried to reproduce the problem in a small sample project, but could not. It worked as you would expect there.

Another thing I have just found. I just tried pasting in an invalid value, and it displayed. When I left the field, it ran the code I wrote to handle this (in the grids BeforeCellUpdate event). But when I paste a value into it, the BeforeCellUpdate event is not triggered.

Its looking like some of my other code (in the grid management/validation side ofthings) is suppressing these events. I'm going to have to try delving through that. Its frustrating that this is happening - that the behaviour of the grid has changed so that it breaks old code.

--- EDIT ---

Nope. Cant find anything. Neither the AfterCellUpdate nor the CellChange events are firing.

Can you give me a hint at what I should be looking for? Is there some sort of cancel update or something that I could be calling somewhere that is causing this?

Hello,

I have created CAS-115946-M4P3W4 to track this issue and I've also submitted the issue to engineering for them to research.

Thanks.

Can you tell me what the likely result of this is? Will there be a patch?

Hi,

I can't say for certain until we've looked into it. But in my opinion, this looks like a bug and it will probably be fixed in an upcoming service release. If, for some reason, a fix is not feasible, then we would at least try to provide you with a reasonable workaround.

Hi Mike,

I have implemented Ultradropdown in my wingrid and it is working perfectly fine. The issue occurs when I copy an alphanumeric/numeric value and paste it into the ultradropdown box, it pops up the error message [Unable to convert from "System.String" to "System.DateTime"]. I tried to debug the code but I was unable to find from where this message is getting triggered.

Please note that it is not a date-time type text box and there is no error message when I paste an alphabetical value. Also, after this error message,  the value gets entered (pasted) as expected. It's just that I need to modify this message to some user friendly message like "copy/paste is not allowed for this field".

Kindly help me out.

Thanks,
Harshit
