I'm working with a .NET WinForms form. I'm adding a new Checkbox control to the layout, but I need its text and checkbox elements to align with existing controls. Is it possible to bump out my Checkbox's checkbox element from its text element? Or am I better off creating a separate Label control?
thanks
Try using the following settings for your CheckBox controls:
checkBox1.AutoSize = false;
checkBox1.CheckAlign = System.Drawing.ContentAlignment.MiddleRight;
checkBox1.TextAlign = System.Drawing.ContentAlignment.MiddleLeft;
You will have to set the location and the size of the control yourself now.
Just create a custom (composite) control by adding a checkbox and a label. set the spacing as per need.

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.
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!
I have a silverlight DataGrid, by default on page load the all the cells of the datagrid should be Readonly. I have 2 problem , can any one help me?
1.On Click on the RowHeader the current row should be editable
2. On click of the columnHearder current column of all row should be editable
This might not solve your entire problem but it should partially address it.
This is to make a column read-only in a datagrid
DataGrid.Columns[7].IsReadOnly = true;
Obviously the property can be changed from events but the data grid does not have row/column headers event handlers. Custom controls seem the way to go without introducing any new gui elements like buttons and changing the feel of the application.
I want to swap images on the button dynamically using mvvm light. When the page first loads,it should display the images as per the database values i.e. checked or unchecked. I have 2 columns for the images like ImageChecked and ImageUnchecked. By clicking on the button i.e checked or unchecked it should change accordingly.If it checked then unchecked n vice versa based on the database values.Images will load on button as Content.
Kindly Help?
Thanks
Are you trying to implement the functionality of checkbox using a button?
If so, you can take a look at the ToggleButton which has the IsChecked and Content properties so that you can change your content using a trigger based on the IsChecked property.
Else if you have the IsChecked property ready from the ViewModel then you can change the image of the button using the Image property using a DataTrigger.
Update
The hierarchy goes like this: ToggleButton->Image->BitmapImage. Set the urisource of the BitmapImage and set it as a source for an Image which in turn is set as a content of the ToggleButton. Do this in xaml. Check this link for creating an Image.
Now set the DataTrigger of the ToggleButton for IsChecked value True and change the BitmapImage's UriSource with the assistance of TargetName property.
