I wish to have a Panel with the controls on it at design time but I want to add this panel to a desired tabPage of my TabControl at run time.
I wrote something like this, did not work : the panel does not show up in the tab page.
please help me.
panel2.Parent = tabGuy.TabPages[0];
tabGuy.SuspendLayout();
tabGuy.TabPages[0].Controls.Add(panel2);
tabGuy.ResumeLayout();
panel2.Show();
You probably need to set the coordinates of the Panel as well, or (better) panel2.Dock = DockStyle.Fill;
And you don't have to set the .Parent or call the .Show()

I have a menustrip that I create using the forms designer. I then want to programmatically add a toolstrip toolbar UNDER the menustrip. The reason is that this toolbar is a set of tools that I add as a plugin to the main application. As such, when the plugin is loaded, I create the toolbar.
When I manually add the toolstrip to the form using the forms designer, the toolstrip is correctly positioned under the menustrip. However when I add it programmatically, it snaps to the topmost part of the form, above the menustrip. Here's the code I use to programmatically add the toolstrip:
stereoBar = new ToolStrip();
stereoBar.Anchor = (AnchorStyles)(AnchorStyles.Top | AnchorStyles.Left);
//y location is set to 22, the width of the menustrip
stereoBar.Location = new System.Drawing.Point(0, 22);
stereoBar.Dock = DockStyle.Top;
stereoBar.Name = "StereoToolbar";
stereoBar.Text = "Stereo Plugin Toolbar";
stereoBar.ShowItemToolTips = true;
stereoBar.GripMargin = new Padding(2);
Controls.Add(stereoBar);
Is there anything simple I am missing here?
Thanks in advance!
As described also in this answer, when docking controls in a form the order in which you add them to the form matters; i.e. when adding multiple controls that all dock to the top, the last control that gets added will be the topmost.
So, because you add your toolstrip programmatically and your menu strip via designer, the designer code gets executed first thus having the menu strip always at the bottom.
I think there are three ways out of the dilemma:
First approach
As Hans Passant pointed out, the easiest way to get things into the right order would be to simply call
stereoBar.BringToFront();
right after you added it to the forms' controls.
Second approach
To circumvent this you could also also add the menu strip programmatically and do this after you added the tool strip.
Third approach
Another way out may be to add another container to the form (Panel or groupbox for example) via designer that also docks to the top that simply just functions as a placeholder where you add your tool strip to (so you do not add to the form directly anymore)
Here is my form
If I click on "Add" on the first panel I want to create "Strategy1_2" just below the first and shift all others panels down.
If I click again I want to create Strategy1_3 (...)
I know how to create a button but not how to duplicate a entire panel.
Here is my code for a button is it far from this procedure ?
private void addstrat1_i_Click(object sender, EventArgs e)
{
panel3strat.Width += 200;
Button addstrat1_2 = new Button();
addstrat3_2.Size = new Size(210, 41);
addstrat1_2.Location = new Point(31,89);
addstrat1_2.Visible = true;
panel1strat.Controls.Add(addstrat3_2);
}
The best way would be that you create a UserControl for your strategy panel. You can then insert the UserControls to a FlowLayoutPanel. This will resolve your issue with placing controls exactly and to create a copy of some panels.
Be aware that you can run out of resources (e.g. windows handles) when adding to much controls on your form. This can be solved by only showing a certain amount of controls and shifting the data through this "fixed" controls while scrolling.
I recommend having two methods: CreatePanelBlock() that will issue a UserControl that you'll add to your container, and BindPanelWithData(...) that will setup the dependencies.
Remember, you may make your panel as a custom control.
I have a usercontrol that I'm adding as a control of a main form dynamically. The Mainform is basically empty, except it has a large status bar on bottom.
Problem is, when I set the Dockstyle.Fill option on my usercontrol, the size of the loaded usercontrol extends beyond the statusbar (It fills the entire main form as if the status bar wasn't there).
How do I prevent this behavior? This is an example of how I dynamically load my form
logicForm = new LogicForm();
this.Controls.Add(logicForm);
logicForm.Dock = DockStyle.Fill;
I think you need to set the DockStyle to None and use the Anchor property instead.
Set the anchor to Top,Bottom,Left,Right and size your control to fill all the space up to the status bar.
You should find when you run that the user control will then resize with the form.
I just found the solution
I need to bring the form to front in order to properly dock it if I already have some other controls on the main form:
logicForm.BringToFront();

I'm working on winfom application c#.
I have two forms called Welome and Details.
Details contains 7 grids in the Panel.
Scenario:
If I click on any of the item on welcome page it will take to the Details page with seven grids. If I drag the scroll bar down, and come back after moving back to welcome form, still the scroll bar stays at the same position.
Question:
I want to reset the scroll position to top each time the user visits the details form, so that I can always see first grid.
Set AutoScroll to true
panel1.AutoScroll = true;
And, then in Details form's load event, set the VerticalScroll
panel1.VerticalScroll.Value = 0;
If Angshuman Agarwal's answer doesn't work for you, the culprit is likely that after load some control in the form is receiving focus, which will scroll into view and override any changes to the scroll position.
You could set TabStop to false, but then your form wouldn't be tabbable :(
A clunky work-around, but still relatively simple fix, is manually fire focus on the first control in your form:
yourFirstControl1.Select();

Old post, but still relevant. The above only worked when I added a line:
displayPanel.AutoScroll = true;
displayPanel.AutoScrollPosition = new Point(displayPanel.AutoScrollPosition.X, 0);
displayPanel.VerticalScroll.Value = 0;
Then it worked great, without having to set any tab indexes.
What is mentioned above is fine but, you should add VerticalScroll.Value in Panel1_Paint
Private Sub Panel1_Paint(sender As Object, e As PaintEventArgs) Handles Panel1.Paint
Panel1.VerticalScroll.Value = 0
End Sub
Is their something like iframe in c#?
I want to build an application with one form that its content changes according to the actions I do, like messenger live. The part when I log in and log out its too different "windows" but it happens in the same form.
There is no iframe equivalent in winforms or wpf, but there are ways to deal with it.
For either winforms or wpf, what you want to do is have a Panel which you change the content of.
A panel is a container which holds/encapsulates other controls.
If you have two different views you want to toggle between, create two panels at the same position with the content you need. Then you will show one and hide the other. When the user executes some action which requires you to change the view, then simply hide the displaying panel, and unhide/show the other one.
Think of it as layers, where you will only show one at a time.
You can also dynamically load user controls into a panel, much like an iframe, but I find it easier to have the content in the form, and hide/show as needed.
Assuming WinForms, how about using UserControls? Place as many as you want in a single/multiple forms, and interact as you do in forms. See, UserControl class.
You can load a form into a Panel or tabPage from a TabControl:
Form f = new Form();
f.TopLevel = false;
panel1.Controls.Add(f);
f.Show();
f.Dock = DockStyle.Fill;
