Is there any way to add/remove additional rows option to **dropdown fields **?
same as the + button in list fields

I'm setting the control source of text fields to return the value of a function (multiple fields with different filtering conditions). The form has a combo box with a list of years: when the user selects a specific year, the on change event triggers a refresh of all the fields.
My problem is the fields don't show any values unless after combo box's On Change events. I have to click on the form/fields before the values start showing up.
I tried to do form refresh & field's requery but doesn't work.
The text field's Control Source is set to:
=SummaryReport("Projects","G","1",[Forms]![frmSUMMARY_REPORT]![cmbYEARS])
What I'm trying to do is when the user selects a year from a drop down, the fields values are updated & displayed by the On Change event - currently they seem to be updated but are not showing unless I click on the screen and that's when values start showing up in each field.
The method to update calculated fields is Me.Recalc (or myForm.Recalc):
https://learn.microsoft.com/en-us/office/vba/api/access.form.recalc
Try this instead of .Refresh.
Also I think the better event to use is After Update instead of On Change for a combo box.
In my form,i have a list of employees in a combo box and i need to map some employees to particular department.I need to change the combo-box to List box.Scenario is as follows,
1. List A contains all employees.
2. If i click 'Add' button the selected employees must move to list B
and list A must contain remaining employees
.
I searched for List box but i couldn't find in extjs4.
Is there any example or link for multiselect listbox in ext-js4?
Thanks
There is no built-in ListBox widget in ExtJs4. However, Ext.view.View may become an listbox after some manipulations.
Here is an example of such a tuned View. Demos may be found here, here and here (this one looks like just what you need).
You can create two such listboxes and the "add" button. Then assign handler to button which would remove selected item from the first listbox's store and add it to the second's store.
I use the following code to fill comboboxes in a datagridview column. The combobox column is created with the designer.
Code in Form1_Load:
Me.Sec_400TableAdapter.Fill(Me.Test1DataSet.Sec_400)
Me.DataGridView1.DataSource = Me.bindingSource1
GetData("select CulType, PrKey, diam from Sec_400 where RdNo = '33-3-33'")
When I run the code, all the comboboxes in the datagridview column properly display "Aluminized" or "Galvanized" items from the Sec_400 table. However when I click the down arrow to see the two options and pick the other choice, all the "Galvanized" and "Aluminized" items from the rows in the datatable are displayed. I just want one "Galvanized" and one "Aluminized" item to show as dropdown menu items.
I've tried entering Aluminized and Galvanized in the "edit columns" designer under "collection items", but after I key them in they are gone when I return to view them. There must be a way to make the dropdown items only two unique values. But How?
I am using telerik's rad combo boxes (dropdowns) on my aspx page. there are 3 rad combo boxes and they are cascading dropdowns. the items in the final dropdown is dependent on the selection of the 2nd dropdown.
Now, i had to insert a "select all" option in the final dropdown. this being a static value, i added it using "appenddatabounditems" property of the rad combo box, setting it to be true. I can now see the select all option, but the items in the dropdown list are repeated. I have used the distinct keyword in the query. Also, when i make another selection in the 2nd dropdown box, the values in the third dropdown are appended i.e they show "Select all" + items of the previously selected 2nd dropdown option + values of the currently selected dropdown selection.
Am i missing something in the query? or there is something wrong with the telerik controls? or the ajax manager?
PLease help.

Are you using the EnableLoadOnDemand="true" setting to perform the cascade? The combo box does not clear the old items out automatically. Two things you can do:
Delete the old items OR
Bind the entire list to the combo box and hide the invalid ones. This has worked for us when the list is relatively small.
HTH.
I am populating a listbox with a large list. The user then has the option of choosing multiple items from this list. I then want to perfrom a few actions on only the selected items.
I cant figure out how to only perform the actions on only the highlighted selections.
'I have tried all combinations of
For each Listbx.SelectedItems.ToString in ListBx.Items.ToString
For each Listbx.SelectedItem in Listbx.Items
'etc, etc
''Performing actions here but it is still doing it with all entries
Next
For Each selecteditem As [Object] In Listbx.SelectedItems
//Your code on each item
