I am designing a windows form in C# and there is a checkbox called "electronic delivery". Under it is a field for "email address". Now I would like to add the option that the email field is only visible if checkbox is checked.
If checkbox is not checked, I would like to have a different field there.
I know how to handle this on the code side, to make things visible/hidden, but how do I place the fields in the form? Should I place one on top of another? Then I won't be able to access the one below to change it's properties.
Or should I keep only one filed and change it's name inside the code?
You could place your controls in FlowLayoutPanel control. The FlowLayoutPanel control arranges its contents dynamically in a horizontal or vertical flow direction.
You could just place them one on top of the other as you suggested. You said you did not want to do this because it would make selecting the properties of the controls difficult.
You can select a control from the combobox drop down menu on the properties section of Visual Studio.
You should create two Different Panels and Add Objects based on the Requirement. After Put visible and Hide Code in the Check Box Checked Event.
Try Panels it Will Work.
You can Simple Move Panel Along with all you objects which make it super Easy.

I have created a form that shows data and the filter that has checkbox in it
combobox
I have used a Button and a Panel to do this and found that the panel is only shown in the parent's panel not float like the combobox
or panel can't do like this?
Regards
You want something that cannot be done with parented components (like panels)
I see some options:
(1) owner draw a combobox to include checkboxes, see Codeprojects https://www.codeproject.com/Articles/31105/A-ComboBox-with-a-CheckedListBox-as-a-Dropdown
or
(2) Create a small floating popup form without system menu and a single pixel border. Inside the form, you could place a CheckListBox docked Fill to allow for filter checkboxes for each item.. you may have a look at this topic Is there a simple way to implement a Checked Combobox in WinForms
(3) Both solutions have drawbacks. Actually it may be better to avoid it, find another way to specify your filter options, redesign your UI.
i used PropertyGrid control to display properties on gridview.
i have taken an reference of this link http://www.c-sharpcorner.com/article/using-property-grid-in-c-sharp/
which is showing like this
But i need checkbox just before the property name shown in red mark on check/uncheck for any property i need to build expression.
I recommend reading this: How do I change boolean properties with one click in PropertyGrid.
It extends the PropertyGrid control and defines its checkbox controls using UITypeEditor.
As Reza mentioned, your choice of control does not appear optimal. You should probably create a form with TextBox, CheckBox, ComboBox etc. Or make use of DataGridView if your display is catering for multiple records at same time.
If you most definitely want to customize PropertyGrid, here is my another answer which might help you start with.
Linked answer:
You can make use of TrackBar. Note that PropertyGrid by default does
not allow you to add controls like these to it. So, you will need to
do some work here. You will need to create a class that inherits from
System.Drawing.Design.UITypeEditor. Next you will have to set the
editor attribute for the property that has to display track bar as
control. Note that unless you do custom paint, it will be shown as
modal dialog or as dropdown editor.
I have a pretty simple winforms application. It contains a rich edit box, embedded browser, progress bar, a few buttons etc.
I have the anchors on the controls set to expand in all directions.
When expanding up and down, however, the controls will overlap one another. How do I prevent this from happening?
Thanks
Your best bet is to add a TableLayoutPanel to your form which contains the "layout grid" this should be docked to the form, then you can add your controls into the cells in the table (they can cover multiple rows and columns so you can get the layout you want).
You must set the property Autosize=true on every control, especially on the main form.
Note that some controls like TabControl have this property, but you can't see it with intellisense (Attribute Browseable=false).
I have created a Windows form using a Tab Control, but it has a header with it. I want to hide it. I am not able to do it using any properties of the Tab Control. Is there any property defined for hiding the tab header for the Tab Control without going through the code?
Use following code to hide the tabs or set these properties in design.
tabControl.Appearance = TabAppearance.FlatButtons;
tabControl.ItemSize = new Size(0, 1);
tabControl.SizeMode = TabSizeMode.Fixed;
You want the tab panels without the feature allowing a user to switch between them, so I suppose you want to create few separate sets of controls to be shown to the user one at a time. You can achieve this in several ways (you can choose one of them if you find it appropriate in your case):
Use several Panel controls instead of several tabs in the TabControl, however, it would be hard to work in the designer, because all the controls would be visible
Use different Forms instead of tabs to keep the layout parts separated. It can be ok, but you may not want to use multiple Forms, so it depends on a specific case.
and finally, the suggested solution:
Encapsulate each set of controls in a UserControl. This allows you to keep each layout separately, so you can easily design each of them without the other controls getting in the way ;). The the code handling each of the layouts would also be separated. Then just drag those controls in the Form and use set their visibilities appropriately to show the one you want.
If none of those suggestions work for you, let me know, so I can look for other possible solutions.
It's more easy as you think, you just drag the panel's window upper, so will be outside of the form.
Use DrawMode: OwnerDrawFixed will hide TabPage header text DrawMode : OwnerDrawFixed
Another way to achieve the same (or similar) is: You can remove tabs from TabControl.TabPages collection and then add the tab you want to show.
During the Form initialization I remove tabs (so into the designer I can easily manage them) and in some control event (as button click) I show the tab the user has to see.
Something like that:
// During form load:
ctrTab.TabPages.Clear();
// ......
// During button click or some other event:
if(rbSend.Checked)
ctrTab.TabPages.Add(pgSend);
else
ctrTab.TabPages.Add(pgReceive);
In this way the user can still see the header tab but just as title of controls group, he can't change/switch the current active tab.
I have a form with a bunch of panels, and some panels inside groupboxes. When using the TabOrder tool in Vs2005, the controls outside of containers are given integers (0), the controls inside panels are given decimals (72.0), and the controls within panels within groupboxes are given three-part values (73.73.0). Unfortunately the resulting tab order has nothing to do with the order I clicked my controls.
Does this tool simply not support nested containers? Am I doing something wrong? Perhaps holding Shift- or Ctrl- when I click (I've tried these with no success)?
Am I going to be forced to manually type in three-part tab orders for all my controls? That would be a bummer.
The tab order tool is not designed for you to enter values manually; it is designed for you to click on controls in the order that you'd like them to progress as the user tabs.
The numbers are not decimals; they represent the tab order of the control within its parent container. For example, if you have a Form with a Panel named panel1 and a Button inside of it named button1, then button1 would display a number like:
X.Y
X is the tab order of panel1
Y is the tab order of button1 within panel1.
I will acknowledge that the designer isn't as intuitive (or transparent) as it probably should be, but it does work.
I had the same problem with textboxes and buttons within group box in VS2010. TabOrder tool was just useless: Tab orders were broken no matter how I re-ordered the tab stops. In order to make the correct tab order I had to re-order of how controls are added to the group box in form designer initialization code:
this.groupBox2.Controls.Add(this.startTimeTextBox);
this.groupBox2.Controls.Add(this.endTimeTextBox);
this.groupBox2.Controls.Add(this.exitButton);
This way tab order would be startTimeTextBox -> endTimeTextBox -> exitButton and so on.
I think I figured out the way to do it in the designer: the trick is apparently that you have to click the panels/groupboxes as well in order to assign the different parts of the full ordering; in this way, it seems that a bredth-first clicking method needs to be used as opposed to clicking the child controls themselves.
Kinda sad, since it forces you to know the full structure of the whole form instead of just what the user sees.
I had this same problem and discovered this tool: http://archive.msdn.microsoft.com/cdstabindex
I had to change the manifest to make it work with VS2010 though. Also, I've modified the source code for myself to make the UI a little better, but even as it is, I would recommend having a look at this tool.
Remove Group-boxes from Controls and try again this works for me :)
