Ok I have been redoing an app I created 4 years ago. I was wandering if there was a way to create a drop down menus using labels.
Currently I have a few buttons on a borderless form and the menustrip is just not looking right.
So I figured if I do a binding on a label I can achieve what I am looking for. I have a label that opens and hides my tab control.
Is there a way to extend that when on the mouse hover event it will produce a drop down menu?
Example
Customize (label)
Commands (tab)
User Input (tab)
Web Commands (tab)
Is it possible to do a drop down menu to list each tab in my tab control individually? My main label Customize opens and hides the tab control.
I really don't want to use menuStrips or buttons or anything because it just does not look right. I have two buttons one is a log out button and the other will be an update commands button once I get the tab Control situated.
If it can't be done then I will just leave it the way it is, and just click the tab I want. The picture below is my main form. I click customize and it brings up a tabControl. I am wanting the form to be border-less. I dont want a white strip going across the top of the form. I am trying to make the form smooth. So when i hover my mouse over customize it will display the tabs in the TabControl. Like a menu. See both pictures below.
Update : This is what i am trying to do, using a Label only. I do not want to use any of these:
toolStrips,
toolStripContainers,
menuStrips,
ContextMenuStrip,
buttons
comboBoxes.
I want to use solely a label. And only a label.
It was painful trying to figure out what you were asking help for, but as near as I can tell, this is probably what you were looking to do:
Size originalSize;
String originalText;
void CustomizeLabel_MouseEnter(object sender, EventArgs e) {
originalSize = CustomizeLabel.Size;
originalText = CustomizeLabel.Text;
StringBuilder sb = new StringBuilder();
sb.AppendLine(originalText);
foreach (TabPage tp in tabControl1.TabPages) {
sb.AppendLine(" " + tp.Text);
}
CustomizeLabel.Text = sb.ToString();
CustomizeLabel.Height = TextRenderer.MeasureText(CustomizeLabel.Text,
CustomizeLabel.Font).Height;
}
void CustomizeLabel_MouseLeave(object sender, EventArgs e) {
CustomizeLabel.Text = originalText;
CustomizeLabel.Size = originalSize;
}

How can I disable a tab inside a TabControl?
(26 answers)
Closed 7 years ago.
I have a tab control with couple of tabs on it, I want to disable one of the tabs while checking a radio button on the other tab page. I can disable the controls on it by using tab.Enabled = False; But I want to know how I am able to disable the whole page from even clicking on the tab. The way I did I can select the tab still, just the controls on it are disable.
There's no native way to disable just one tab and leave the rest working. You'll need to make your own TabControl and use the Selecting event to detect when someone is about to enter your tab and disable it.
Here's a really basic example that stops you from entering tabindex 1.
// Make your own control deriving from TabControl
class CustomTabControl : TabControl
{
// Subscribe to the Selecting event
public CustomTabControl()
{
Selecting += tabSelecting;
}
private void tabSelecting(object sender, TabControlCancelEventArgs e)
{
// You would put your own logic here to detect which tabs to disable
// For this example I'm disabling access to tab in index 1
if (e.TabPageIndex == 1)
{
e.Cancel = true;
}
}
}
If you want the tab to grey out you'll need to override the DrawItem even and paint the tab yourself. If I have the code for that I'll update my answer in a bit.
Edit: It seems the example for custom drawing is pretty long, but here is the tutorial I used to create my own tabs.
http://www.codeproject.com/Articles/91387/Painting-Your-Own-Tabs-Second-Edition
My scenario is the following:
I am working on a winforms application in C# that has a button inside the main page of a tabcontrol that will generate another tabpage each time that it is clicked. Each new tabpage will contain a layout defined by a user control.
My Questions are:
How can I allow the user to then close one of the tabs that were created dynamically at runtime?
How might I go about modifying the tabcontrol itself so that it has a small 'X' in each tab that the user may click on in order to close that particular tab? (Like Firefox has)
How can I expose the SelectedIndex property of the tabcontrol to the user control if I want to close the tab with a button inside the user control instead?
I found this code and was very helpful to me:
private void tabControl_MouseUp(object sender, MouseEventArgs e)
{
// check if the right mouse button was pressed
if(e.Button == MouseButtons.Right)
{
// iterate through all the tab pages
for(int i = 0; i < tabControl1.TabCount; i++)
{
// get their rectangle area and check if it contains the mouse cursor
Rectangle r = tabControl1.GetTabRect(i);
if (r.Contains(e.Location))
{
// show the context menu here
System.Diagnostics.Debug.WriteLine("TabPressed: " + i);
}
}
}
}
TabControl: How To Capture Mouse Right-Click On Tab
I created a derived tab control about one year ago. I am not going to post the source here, because it's about 700 lines long and coded quite messy. Maybe I will find some time to clean the code up and then release it here. For now I will briefly outline the way it is build.
Each tab page has a 'X' icon to the left of the title and the tab pages support reordering by drag and drop and moving them between multiple tab control.
I choose the easy way to get the icon on the tab pages. The tab control has the TabControl.ImageList property and a tab page has a TabPage.ImageIndex property. So I just added three icons to a image list - normal, hover, pressed - and process the mouse events.
With TabControl.GetTabRect() you can test if the mouse is over a specific tab pages and with some math you find if it is over the icon. Then you just need to change the icon depending on the mouse button state and eventually remove the tab page under the mouse if the button was pressed.
The main problem with this solution is, that calculating if the mouse is over the icon requires to know where the icon is painted relative to the tab page and this might change with a new windows version. And the icon is to the left of the title, but that does not look too bad.
I did the following:
on the create (add) TabPage stage, I added a toolStrip
ToolStrip ts = new ToolStrip();
ts.Dock = DockStyle.Top;
ts.RightToLeft = System.Windows.Forms.RightToLeft.Yes;
Then, create the X button and add it to toolstrip
ToolStripButton ToolStripButton = new ToolStripButton("X");
ts.Items.Add(ToolStripButton);
create an event on clicking the X button
ToolStripButton.Click += new EventHandler(ToolStripButton_Click);
add toolstrip to the tabpage
tabControl1.TabPages[curenttabpage].Controls.Add(ts);
now for the ToolStripButton_Click is as follows:
void ToolStripButton_Click(object sender, EventArgs e)
{
ToolStripButton t = (ToolStripButton)(sender);
ToolStrip ts = t.Owner;
TabPage tb = (TabPage)
(ts.Parent);tabControl1.TabPages.Remove(tb);
}
Maybe it is not as you want, but it will work well.
I created a setup that is similar.
Each control that is added to the tab page at runtime is derived from a special base control I created. This base control has a close button (along with some other features such as safe to close flag).
Close tab code I'm using on my base control:
TabPage tabpage = (TabPage)this.Parent;
TabControl tabControl = (TabControl)tabpage.Parent;
tabControl.TabPages.Remove(parent);
I know this is an old thread but I did find this link that will allow you to "hide" tabs in an array and then you can just re-load the tabs you want at run time. I added this more for a place I can easily find it again.
This code might help throgh closing the tab controls with middle mouse click :
private void tabControl1_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button != System.Windows.Forms.MouseButtons.Middle)
return;
for (int i = 0; i < MainTabControl.TabPages.Count; i++)
{
if (this.MainTabControl.GetTabRect(i).Contains(e.Location))
{
this.MainTabControl.TabPages.RemoveAt(i);
return;
}
}
}
It´s works!
TabPage tabpage = (TabPage)this.Parent;
TabControl tabControl = (TabControl)tabpage.Parent;
tabControl.TabPages.Remove(tabpage);

Change content in a windows form
(2 answers)
Closed 10 years ago.
I'm using visual studio 2010 and I have a winforms application.
When I start the application I show the user the 'MainMenu' which have:
1) New Game button
2) Options
each button click create a new form...
what I want to do when the user clicks on the options button is to change the MainWindow
content to be the Options window content.. and when he accepts the
changes on the options window -> return to the mainMenu view.. is it possible to do?
You could either use Panels and switch them round:
panelMain.Visible = false;
panelOptions.Visible = true;
Or you could have a numerous forms, and show and hide them:
frmOptions.Show();
frmMain.Hide();
Create multiple Panels and hide and show these on Button click.
Button_Click(object sender, EventArgs e)
{
PanelNewGame.Visible = true;
PanelOptions.Visible = false;
PanelMain.Visible = false;
}
Depending on the button you click handle them differently
One way you could do it is to use invisible labels and text fields for example, and when the user clicks the Options button then everything becomes clear.
I would advise that you take a look at the Tab Control class. This control allows you to switch between different blocks of content programmatically using the command
tabControl.SelectTab(i)
where i is the index of the tab.
Grabbed the images from a similar question in WPF. Basically I want the extra buttons to do different things, not create or delete tabs. Actions related to the current tab which are gonna be the same for all the tabs in a single TabControl.
When I try to place my buttons on that area, the visual studio designer throws my control away, back to their original position. It doesn't allow me to put anything there.
Can this be done?

For specifically that visual experience I'd just create a separate tab with header "+" and add some logic on switching to it - so it will perform some other action instead of switching. The same can be done with multiple tabs I guess.
UPDATE
Actual code for this:
private void TabControl1_Selecting(Object sender, TabControlCancelEventArgs e)
{
if (e.TabPage... /* Do check whether some of your special TabPages is being selected */)
{
e.Cancel = true;
// All other TabPage-specific actions here
...
}
}
So it looks like they are using a tab as a button here. I would imagine they have the tab controls index change event fire a new tab into the tab control and force focus to it.
In a C# GUI program how do you move a tab control to the front on the click of an object?
I have a picture box on the main tab, when the user clicks on the picture box, I want the second tab to be pulled forward.
Visual Studio 2005
Cheers.
Are you trying to select a different tab or bring a TabControl in front of a different control?
If the former, write tabControl.SelectedTab = someTabPage in the picture box's Click event.
If the latter, write tabControl.BringToFront().
You want to handle the Click event on the control (add a handler to Control.OnClick) containing the picture, and if you have tabControl and myTabPage is the tab page that you want to be selected after the click, you would use TabControl.SelectedPage:
tabControl.SelectedTab = myTabPage;
In particular, since you refer to the "second tab" then you probably want
tabControl.SelectedTab = tabControl.TabPages[1];
To select a different tab, set the SelectedTab index from your handler:
// select the second tab in the control
tabControl1.SelectedTab = tabControl1.TabPages[1];
