I have a great application with an initial form. This form has a menu strip with four "buttons" like this:
My Form with menu strip
This main form contains another form with more applications. What I want to do is when I open another form (application) I want to hide only the menu strip item called "Cambiar Empresa".
What I have thought is to make visibility false when I am in another form, but I cannot call this form because there is a problem of circular dependence.
How could I do this?
EDIt:
The second form is in the pink line and the main form is in the blue line:
Estructure
Thanks in advance!

I have a GMap.NET control on my main form, and then I have a second form that will show when the user clicks on a button. The problem is, that when the user leaves the second window and hovers over the GMap control from the main form, the main form comes to the front. This does not happen when i hover over the rest of the main window with the second window on the front. Also I have another form that will show while the program searches for some data, and this one will also disappear when the user hovers over the map.
I hope I explained it well enough, basically when I hover over the map the main window comes to the front. And it does only happen when there is another form of my project in front of it, not when there is any other window like firefox or something in the front.
So my question is: why does this happen and can I change this behavior? Is it a standard of the GMap.NET control? I am using the Version 1.7.0.0 control btw.
you must use
GMap1.DisableFocusOnMouseEnter = true;
i added this code to my program and problem solved.
It would help to see some code as to how you are showing the forms, but it sounds like you are doing something like secondwindow.Show() instead of secondwindow.ShowDialog(), and then an event from GMap for OnEnter is doing a Focus().
Then, when you have the "other form" in front of it, it's opened in a way that will restrict access to the parent form (ShowDialog(), etc).
I am doing my college project onclick event I do not want to open a new form but show the component in the same form by disabling the components of the previous option.
For instance, if I click on ADD button, it will open a new form with details to be added to save.
But, I want to show all those components of ADD form in the same form where click event occurs.
My design is something like, all options will be in left hand side and the result / form with component has to be displayed in the right hand side without opening a new form.
Use Panels.
The Panel Control is a container control to host a group of similar child controls. One of the major uses I have found for a Panel Control is when you need to show and hide a group of controls. Instead of show and hide individual controls, you can simply hide and show a single Panel and all child controls.

Use Panel Control
Add multiple panels one over the other, like a stack.
Either use:
panel1.Visible=false ; panel2.Visible=true on button click
panel1.Enabled=false ; panel2.Enabled=true on button click
according to your design

In Form1 I'm enabling IsMdiContainer and I added a MenuStrip. In Form1_Load I "new" Form2 and I'm assiging Form2.MdiParent to this which is Form1. I'm also maximizing Form2 and this operation works well.
In Form2 I have a treeView on the left side of the form and on the right side of the form I would like to display a number of different forms with various editing capabilities which will be dependent upon the node or level selected in the treeView.
I would like to create a number of different forms for editing data that would be displayed in Form2 depending on the selection from the treeView. I can't seem to add a form to the MdiChild and I've been seeing some posts where adding a form to a form may create some programming problems which I'm not sure about.
I really don't have any code to paste into this post because nothing seemed to work except for the Mdi Parent and Child relationship which was pretty simple.
Thanks in advance for any help.
There is a lot of information on this subject, but some documentation can be difficult to understand for some new developers. Follow these steps:
Open Visual Studio
Create a Windows Form Application
Click your Form
Go to Properties for that Form
Minimum Size : 1366 pixels by 768 pixels.
Launch Maximized
The important element is IsMdiContainer
Open your Toolbox.
Go to Menus
Drag FileMenu onto your Form
Build your Menu
Then go to Solution Explorer
Right-Click Add Item
Add another Form
I left mine as Form2 (In a real program, not a good name).
So within those fifteen steps, we have all that we need to accomplish our goal. So what we will do to finish our task is:
Go back to our First Form
Go to our FileMenu
Double Click on the menu button you wish to link.
It will load a code view, inside the area put this:
Form2 newFrm = new Form2();
newFrm.MdiParent = this;
newFrm.Show();
What this code is doing is three distinct things:
Line 1: It is actually calling our object, in this case a second form. It is actually building our object for us.
Line 2: Is actually linking our second form to our current form, this is physically turning our second form into a Child Form.
Line 3: This is actually physically showing our second form when the button is clicked.
That is all you need to physically show a Form.
In regards to your second question, I'm not entirely sure what your attempting to accomplish. It sounds like your trying to have a tree, then as a Node is selected the right hand side of the Form changes to specific context.
Now this isn't the nicest example, but do you mean something like this?
TreeNode node = treeView1.SelectedNode;
if (node.Text.Contains("XP"))
{
TextBox one = new TextBox();
Panel i = new Panel();
i.Dock = DockStyle.Right;
i.BackColor = Color.Black;
i.Controls.Add(one);
i.Show();
TreeFrm.ActiveForm.Controls.Add(i);
}
Not sure if that is what you are seeking. Obviously you'd want to implement a FlowLayoutPanel to make the positioning not a pain for you. Keep in mind an MDI Parent, with a Child Form acting as a MDI Parent will not work very well. As most things will default to MDI Parent Forms Docking / Positioning. This example is not pretty, but I'm not entirely sure of what your asking.
Are you trying to dock other forms or components on the same form?
lets say i have a main form which have a lot of functionallity.
this form have a tab control in which each tab contain some set of functionality.
what i want to do is when i click on each tab controls button i want to load a form into the client area of the tab control.
so instead of having a lot of controls in the main form , i will only have set of forms and each form will have its control.
i think this is will be better in term of managing the controls so i dont have like 150 control on the main form.
so basically i want to load a form on another form and not show the form in a seperate view.
if its not possible with forms then can i use another control that will group the controls and will be loaded on the main form?
thanks
Alternate 1 :
You can make each of the form as a User Control and then you can load the appropriate user control in a blank panel in your main form whenever required.
You should be able to find a way to communicate between your form and those user controls.
Alternate 2 :
You can show the appropriate Form using ShowModal() method, with the main form as parent, that way user can finish the work with the child form, before coming back to the main form.
Disadvantages here are user wont be able to interact with the main form as long as the child form is closed.
I would recommend looking into User Controls.
User Controls come with a designer, just like forms, and have a rich event model to tap into. Unlike forms, they are easy to embed into other controls and forms. As a matter of fact, user controls will show up in your toolbox to drag-and-drop onto another form.
It's at least worth taking a look at.
Following code adds one Form to a panel in another form.
Add this code in Form1
Form2 ff = new Form2();
ff.TopLevel = false;
ff.Dock = DockStyle.Fill;
ff.ControlBox = false;
ff.Text = "";
panel1.Controls.Add(ff);
ff.Show();
The flip side is your panel should be big enough to accomodate the form...
Thinking about this for an About dialog but I'm sure it's applicable in other places (say a find box)
Sorry if this is a dupe, but I couldn't find this or how to articulate the last part about it only being on top of the parent. How do you make a form that is always on top of the parent form, but is non-modal, but doesn't cover up other apps?
Try this to open your dialog:
FindDialog fd = new FindDialog();
fd.Show(this);
The key is to assign dialog's owner.
Not sure exactly what you mean; Form.ShowDialog is only modal with respect to the parent, not the application, unless the application is single threaded.
For example, I made an app to test this which was organized like the following:
mainform:
2 buttons, each of which begins a thread that creates a frmDialog1 and calls ShowDialog
frmDialog1:
single button which creates a frmDialog2 and calls ShowDialog on it.
frmDialog2:
does nothing (ie. blank)
when they were all running I could access/drag mainform. I could also do the same with frmDialog1 (both versions) only if I hadn't clicked the button that shows dialog 2.
