In winrt windows phone app when you have more than 5 items in a combobox, it opens up on a full screen. And on top its written 'Choose an item'.
I want to remove this heading from all my combo boxes.
you can set PickerFlyoutBase.Title property of combobox to either with space or text of your choice. So it would be like:
PickerFlyoutBase.Title= " "
or
PickerFlyoutBase.Title="Some text"

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.
There are nice solutions to the problem with combobox and prompt in WPF, but in my case I have mixed items -- image and text. So for example this solution (copied from https://stackoverflow.com/a/11671997/210342):
<ComboBox Name="MyComboBox"
IsEditable="True"
IsReadOnly="True"
Text="-- Select Team --" />
works fine as for prompt, but it has side effect, that when I select an item, the item in turn is not displayed correctly as selected -- it is presented in list OK, but after selection all combobox shows is System.Windows.Controls.ComboBoxItem.
So how to have a prompt (I don't insist of fixing this approach) and properly displayed mixed items?
I solved this in ugly way. I added a grid, put this combobox in the grid with ZIndex=0. I added extra button to the grid with ZIndex=1. This way I get an overlay. Any time users clicks on the button (combo is initially hidden) I open combobox programatically. When users selects anything from dropdown list of the combobox I hide the prompt button.
In windows form, I have 5-7 combobox on one 3 tab pages of tab control.
This tab control reside in a group box.
There are other two groupboxes containg other text box and listview controls.
Problem is, When defualt load the form control then focus set on combobox and unable to unselect.
Tried by changing property- causevalidation to false but no output.
Please guide.
Add a line on Page Load to set focus on the control you want to focus.
For Ex:
txtName.Focus();
EDIT
Use this
ActiveControl = yourcontrolNameToWhichYouWantToSetFocus;
You can set the TabIndex of the controls, the lowest index will be the first focused. (TabStop should be true)
I you want to set focus to another combobox you should call Select() method.
I am using devexpress gridcontrol in my desktop application. But I am facing a problem with tooltip.I used the repositoryHyperlinkbutton and it has 3 buttons in it named view, edit, insert
Now I want to display a tooltip for that three Buttons. I already set the property for it.When I use single form the Tooltip work fine. but when I used that form with MdiParent at that time the Tooltip is not display.
This Problem is solved in above the devexpress 11.5 controls.
I done it.
The cells in a GridView contains no controls - they are only painted. When you click a cell, its in-place editor is created (or - in this case - the 3 image buttons). No controls = no tooltips!
is it possible to change a combo box to text box using vba?
As an addition to the suggestion about hiding the text box I have seen people use a text box to cover all but the dropdown arrow of the combo box (text box set to be on top of course) and then updated the text box on the after update event of the combo box
I forget why they did it that way in the end but it worked and IMHO is better than hiding the combo box as you might have issues with it still having focus
As far as I know there are two methods. If the form is in design mode then running;
Application.RunCommand acCmdChangeToTextBox
while the combobox is in focus will make it turn into a textbox.
However you cannot do this at runtime. Say you want to show a textbox after selecting a value from the combobox, on the Change event of the combobox you just hide it and show a textbox that was previously hidden. Use the visible property of the combobox and the textbox for this.
