I have a user control that consists of some textboxes and checkboxes. Once the user is finished filling the first one, they should be able to add one more form by clicking an "add another record" link button.
How can I repeat this usercontrol as the user clicks?
I am supposed to use C# only.
So, we are talking of UserControl where your fields are located (I mean, that this is a one class inherited from UserControl or Control. )
There are a lot of ways to do it. But, I think, to be mode 'code concise' is to use FlowLayoutPanel
a) Create this panel. (through visual designer i.e.)
b) When user clicks, create your control
c) add your control to layout panel.
var myControl = new MyControlWithForm();
flowLayoutPanel1.Controls.Add(myControl);
One could use flowLayoutPanel1.Controls array to process all filled forms afterwards.

In windows form application, i created a usercontrol page. Here, I need to add a myowncontrol from tool box.
I just added myowncontrol in the tool box. by the way of browsing dll and placed it in tool box.
Here, when i drag and drop any one of default control, which can easily dragged and placed in the usercontrol page. But when i try to drag and drop myowncontrol into usercontrol page , its not working.
Can't able to drag and drop.
(i mean i can pick the control from the tool box but i can't able to place it where i want)
what is the problem in my area?
I'll admit that this does not directly answer your question, but I am wondering if you have tried to programmatically add the control to a Form? You would need to add a reference to the DLL that contains the UserControl and then do something similar to below in your source code.
var myCtrl = new MyControl(); //your UserControl class here
myCtrl.Location = new Point(25,25); //give it a location
this.Controls.Add(myCtrl); //add it
Also another thought... Are you sure that it's not really being added and it's just not visible? For a Form or UserControl in the Visual Studio Properties Window there is a drop-down at the top which contains all the controls that have been added.
I want to change my form 1 into form 2. I don't want it to open a new window but keep it in the same window and then be able to go back and forth when I press the Next key or back key. Is the only way to do this by Individually hiding each button and picture?
You might want to consider a different approach.
You can't change one type of form into a different type of form. The closest option would be to close or hide the first and show the second at the same location on the screen.
However, you could approach this differently. Instead of putting your buttons and logic into a form, you could place everything into two UserControl instances, and just change which user control is visible within a single form.
You can use panels, group boxes, TabControls, etc. to group common controls together. When you want to switch between different "screens", you can hide or show the group control by setting the visible property and calling BringToFront(), and it will hide/show all the controls on that group control.
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.
This is what i intend to do .
Form 1 is displayed , requesting some data .
Cliking the next button would display form 2 requesting some more data .
Back button will take it back to form 1 .
Finally at the last form on clicking a finish button , Id like to retrieve all the data and display it in one singe form . I would like to know what is the best design approach should I follow
Ie : Do i have all the controls in a single form and make them visible and invisible .. ?
or should i have multiple forms with global values to be accessed in the end?
I would recommend that you create user controls for each tab except maybe the last and encapsulate all the logic for that tab within the control. Add properties to the control to get the values entered on the form. Add all these user controls to a parent form which handles navigation.
I think you can achieve this by IUIs (Inductive User Interfaces)
Its just like as Dark Falcon has mentioned above.. you can create a parent form and add user controls which would inherit the navigation controls and tabs from the parent.
I have a .NET forms application using a tab control with several tabs. There are a few elements (a button and a few text boxes) that need to be displayed on every tab. Rather than create 5 seperate elements (including all the appropriate properties), is there a way to create "links" to one element?
For example, when an event occurs, I need a textbox to display the same information in each tab. As it stands, I need to create a new textbox for each tab, then explicitly write to each. It would be easiest to just write to one textbox, then consider the rest "links" which automatically update.
Those controls really ought to be somewhere else than on a TabPage. But you can get what you want by implementing the SelectedIndexChanged event and change the Parent of the control. This sample code keeps the text box on the selected tab:
private void tabControl1_SelectedIndexChanged(object sender, EventArgs e) {
textBox1.Parent = tabControl1.SelectedTab;
}
Sorry, there isn't any way to do this. controls on a form are childen of that form, they can't be simultaneously children of multiple forms. (a tab is basically a sub-form).
You could either create an array of references to all of the textboxes that you want to behave the same, and and write to all of them when you write to one of them. Or
keep the text in some location outside of the textbox, and update the textbox on the visible tab when ever the user changes tabs.
