Win Form: Is there way to get the results from Auto Complete (FileSystemDirectories)? I am trying to write my own custom drop-down list instead of using the the original Textbox Control AutoComplete drop down list. However, I want to use the Textbox Auto Complete Source: FileSystemDirectories to display to my own custom drop-down list. How can I do it?

I'm using Material Table at the moment and am having difficulty customizing the position of the selection text (presented when one or more rows are selected via the checkbox).
Looking at the documents, I can see that the toolbar is overridable (https://material-table.com/#/docs/features/component-overriding), however the examples show simpler changes e.g. how to change the background color. I wonder if it's possible to separate the selection text from the toolbar and render it in a different location, like the below picture demonstrates.
Does anyone know if this is possible?
In the end, I turned off the row selection text in the toolbar by using showTextRowsSelected: false
I then made a custom footer using the row data presented by the onSelectionChange handler.
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.
I want to create a ComboBox having Checkboxes as children using Codename one.
I am not using the UIBuilder
For reusability I created a Container having three Checkboxes in it:
OverviewCheckBoxContainer
- Checkbox1
- Checkbox2
- Checkbox3
and this works already.
As it takes too much space on the screen, I now tried to add the CheckBoxContainer into a Combobox, like this:
ComboBox
- OverviewCheckBoxCont
-...
but it does not work, the ComboBox contains a single entry only and it's not a checkbox, but a text:
OverviewCheckBoxCont[x=...
(cannot see further on the screen)
How can I solve this issue, so there is a dropdown menu containing the three Checkboxes, that toggle onClick?
ps:
In the main form I added the CheckBoxesComboBox instead of the CheckBoxesCont:
this.add(BorderLayout.CENTER, checkBoxesComboBox)
instead of
this.add(BorderLayout.CENTER, checkBoxesCont)
1.You can use simple combobox as shown below
ArrayList al = new ArrayList();
findComboBox().setModel(new DefaultListModel(al));
2.And to add checkbox in combobox , you have to customize the combobox
3.Instead of customizing combobox, You can use button which shows and hides OverviewCheckBoxContainer which contains list of checkboxs
See this for customizing the ComboBox with the generic list cell renderer: https://www.codenameone.com/manual/components.html#_combobox
The problem with using checkboxes in a combo is that you would assume they would all appear in the combo as a set and the combo wasn't designed to do that. I would instead just use a Button and show a dialog with a set of checkboxes then set the text of the Button to match the result. You can style the button to look like a ComboBox if that is your preference.
If I setup a lookup for a field when designing a table (i.e. through the Lookup Wizard) and I set "Allow Multiple Values" to "Yes", a multi-select combobox (i.e. with check-boxes) is displayed in the relevant field in the "Datasheet" view of the table. My question is the following: Is the text-box component of a multi-select combobox control actually of any use? While a single-select combobox lets you type a new value that is not in the list or facilitates the auto-complete feature when typing a value that is included in the list, but the multi-select combo box prevents you from typing anything in its textbox, and that behavior doesn't seem to change via the properties of the combobox control.
The reason I need this feature is because I want to type there something not in the list, in order to trigger the control's NotInList event, so that I can update the corresponding lookup table with the new value I typed.
Thanks
I have a ListView form that looks like this:
How do I make it so each cell is like an editable textbox so the user can edit the values by clicking on a cell? Like if they click on "Count" a text edit cursor should appear in-place and they should be able to type to change the value of the field (Not in a separate dialog box or text field)
The ListView is intended for flexible display of a list of items. Similar to windows explorer's ability to show icons, thumbnails, details and basic list, all from the same set of objects. If you really want to edit all of the elements in your data objects, you should probably read up on DataGridView and data-binding.
