devexpress gridcontrol lookupedit repository item disappears - devexpress

I have the following:
an unbound gridcolumn, UnboundType set to String
this column has a lookupedit repository item
for this repository item I set via code the displaymember and valuemember properties and the datasource
I set the Fieldname of this column too
the Fieldname, displaymember and valuemember are exact the same
But if I run the app and select an entry, then click away, the entry in this column disappears.
Yes, I have googled and found this issue too, but I think, I have set all the things right to get the right result, or not?
Can somebody point out, what can be the problem?

Binding column text property to another property with refresh (JavaFX)

Could somebody tell me how shold I approach binding the text property of a column header in a TableView to another property, that can be changed with a combobox selection?
I tried column.textProperty().bind(myProperty) , but the column header doesn't refresh the text when myProperty changes. It only happens after I click on the column header as if I wanted to sort the column. Is there any way to make it refresh automatically when changed ? Or does anybody have other suggestions how to approach this ?
Found out it was because I've accidentally put the method that changes the property into a block that runs in a separate thread.

Access 2010 : Allow combox box search, but lock for edit

I'm just reacquainting myself with Access after a long absence and am getting hung up on some relatively minor things !!
I have a form designed so users can select a ReportID from a combo box and the other fields in the form populates the information. That works great, however I don't want users to be able to update the fields, it's for reference only.
If I lock the form for editing then the combo box select doesn't work - is there a way that I can have a combo box control a form, but not allow editing or updating of any other returned fields ?
Set the fields Locked property to Yes.
You have to change two properties of Combo Box under Data tab Under properties. Following are the properties to be changed:
"Limit To List" the default value for "Limit To List" is "No" change this to "Yes"
"Allow Value List Edits" the default value for "Allow Value List Edits" is "Yes" change this to "No"
After doing this modifications on the default values the user will be allowed to modify the text in the Combo Box, but when the user is leaving the Combo Box the BeforeUpdate event will be fired and the user will get an exclamation message from MS Access.
See the below given pictures for more clarity. The first picture shows the default values, second picture shows changed values and the third picture shows the message if values are edited.

Kindly reply to this message if this solves your problem.

Make sure your combobox is unbound (not linked to a field by its ControlSource property)
position it in the form header (not the Detail section)
set the form's Filter property to the combobox using the expression builder (button with '...')
also set the form's FilterOn property to true

Flex: Combobox creating dropdown with less values

I have an object that inherits from combobox. This is done so I can use a custom framework for creation and value setting and uses a 'id' / 'description' set for the dataprovider. When I set the value, i set the 'id' and the custom object looks through the dataprovider to find the matching id to find the index. When setting the value, I don't know the 'dscription', that is what the row source is for.
My problem is in that I need to display 'old' values when I first set the value through code, but I don't want to allow the user to see the 'old' value in the dropdown and allow them to select it.
Now, I've been trying to chase down the best way to do this. I'm assuming I need to either interrupt the creation of the dropdown dataprovider and populate it with a smaller list(using my own 'hideFromDropdown' property) or find out if there is a way to add a property to my dataprovider that causes the item to not be rendered by the dropdown. Perhaps eich 'item' in the dropdown has a visible property?
I was able to trace down to the combobox.getDropdown method, which creates a new dropdown from the dropdownfacrory. Unfortunatly, this is private so I can't override it to pass a partial rowsource. Now, all the dropdownfacory seems to do is return a basic list. Unfortunately I keep getting lost tracking down to find the place in the list or listbase objects where the individual item in the dataprovider gets rendered(or not). I believe I have traced to listContent:ListBaseContentHolder in ListBase which contains the data, but am constantly getting lost in the ambiguities.
I am using Flex SDK 3.6A in Adobe Flex Builder 3(built on the Eclipse engine)
You can use filterfunction on the dataProvider like arrayList/arraycollection. Checkout the example here

Checkboxlist latest checked/unchecked item

I have a need to get the latest checked or unchecked item from a checkboxlist. Basically I need to detect any change in the list and perform some action on that.
I found the solution for latest checked item but couldn't find one for the latest unchecked item.
Is it possible to do that with the checkboxlist or I will have to go with another control?
I know this thread is old...but might as well throw an answer out there. One option is to create a datatable for the selected items in the CheckBoxList(CBL) on databind, scrub that table against the selected items in the CBL, and find the difference.

Displaying checked items in CheckedComboBox in DevExpress using C#.net

My current CheckedComboBox has a large list of items. I need to have selected list out of those items checked when the drop down is clicked. e.g CheckedComboBox will have P,Q,R and S as the itmes. But only P will have a tick in front of it.
Is there a property for this defined already?
Thanks
The CheckedComboBox control does not provide the CheckedItems (or SelectedItems) property .Use the editor's EditValue property to determine which Items are selected.
