In my form I have a Barmanager, in which I have a comboboxedit1. I want to know how to access to the selected item of the baredititem1 (combobox). In the normal combobox it is:
dim q =combobox1.selecteditem
but I can't do the same in a baredititem1 wgich is placed in a barmanager.
You can grab the current selected value using the barEditItem1.EditValue property, or while the editor is activated, you can access the current editor instance by BarManager.ActiveEditor property, which you should cast to ComboBoxEdit in your case. You can read about this more in the documentation, where they explain why you cannot access the concrete editor anytime you want.

I am trying to figure out how to add placeholder string value on every property inside a property grid that was not changed from the user.
So let's say you are trying to edit some object when you get prompted to do so you will get the following form.
If you changed the color property for example the result would be the following.
I tried to see if there is an attribute but it seems that there is not. DefaultValue is not suitable because the message is a string and the underlying property could be anything.
The question is if this is possible using combinations of Editors and TypeConverters.
Thanks.
I have a view that contains several ComboBox elements. For some reason old data remains from the previous time the view was opened and I would like to reset the combobox elements in the view every time it is opened. Is there a function that could that for me? I want it to be exactly how it is as if I rendered it the first time with the initial items. Would using setSelectedItem(vItem), setSelectedItemId(vItem), setSelectedKey(sKey), setShowSecondaryValues() help? If so, what do these keywords mean (selectedItem, selectedItemID, selectedKey, secondaryValues)?
Unfortunately you do not provide an example. Normally you bind your UI controls against a model, e.g. JSONModel. In this case the items of your ComboBox controls would be taken from the corresponding model. However, you can use method removeAllItems to achieve the desired behaviour.
UPDATE: Obviously the controls are bound and only the selection should be cleared.
Use setSelectedItem with value null to clear the selection. You could also use the binding to set the selected item automatically by using the selectedKey attribute, see example.
Have a question - I'm having an issue with passing .text to a combobox that has a style set to LIST. I'm not sure why the issue is. Basically have a combobox that's populated with a lot of data. To make matter simple, I've created an additional form where user has a whole screen from where they are able to choose an item. The new form has the SAME EXACT items that combobox has - so when I pass the text from the new form to Combobox 2.0 - I get an error 380 - text propery is not set correctly
are you using the .AddItem method to add your text items?
I have a VB6 application that has been running for quite sometime. Currently I'm trying to update one of the form that has a combobox 2.0. Because the combobox is populated with hundreds of items - I'm trying to update it so that users are able to click on a look up button next to it, where another window opens up with all the items from the combobox. User will be able to search by keyword and/or select an item and double click on it and have it appear in the combobox. The issue I'm having is with trying to pass no value or "" when CANCEL is clicked. I'm able to pass the value if I in the properties window my STYLE Is set to COMBO rather than list. However, the issue I come across is that with COMBO the value (text) in the combobox sometimes is not aligned properly. Is there a way to pass a "" value to a combobox 2.0 without changing the style to COMBO?
If they hit cancel set the ListIndex of your combo to -1 rather than setting the text property. This is the value for no item being selected.
Excel provides you with a checkbox control that you can use a property called "Cell Link" to define which cell the checked property for the particular checkbox is linked to.
When using VSTO, I'd like to do the same, but unfortunately I can't put in an Excel Checkbox control and have to use a Windows Forms checkbox control. This doesn't contain the same "Cell Link" property with which I could bind to a particular range.
Any idea how I could achieve the same thing in VSTO?
