I'm making a windows form application with tabs, and in my first tab I have a overview of the active tabs. Now when I add a new tab, the tabs are going in a sort of scroll bar and when the scrollbar is 'full', my first tab becomes 'out of sight'.
Is there an option to keep the first tab always visible? I've searched around the internet and couldn't find someone with the problem nor solution
I didn't see any property for it yet but you have two way:
1) Create a custom control yourself (long way)
2) Use Multiline property of tabControl and set it to TRUE (Short way)
// Allows more than one row of tabs.
this.tabControl1.Multiline = true;
Result:................................
When you set Multiline to TRUE, it keep all tabs always visible (include first Tab) ;)
Also you can set Appearance property to Bottom or FlatButtons to prevent tabs moving after click on them in different lines.
this.tabControl1.Appearance= TabAppearance.FlatButtons;
No there is not. You would need to design your own control to do this if that is what you want.

I have an application where I have several forms. Its a C# windows-form based application build in .NET 4.O. I have several forms where the user enters the data. There are grids where data is displayed and whole lots of controls on the form. Believe me! its a mess of so many controls. I have to setup the TabIndex for each control. I have literally disabled the TabStop property of certain controls I don't want to be tabed into it. However, still once I go through the order I want, I TAB it, and it works but once it reaches the last box then it takes 3-4 times more tabbing to get to the first field. I tried disabling the TabStop property for the controls I don't want. But I think there might be certain controls that I don't see but they might be included in the Tab property.
My question is that is there any way that I can set the TabStop property of all the controls on the winform to false and then set it to true for the controls I want to include only.
I also open to if there is any other way I can implement this?
If further explanation is needed, let me know!
I have attached a picture thats the order I want and then loop back but somehow its not working. Just in addition there is also two panels in the form and I have disabled their TabStop property to False.
Go to View menu and click Tab Order. This will activate the tab-order selection mode on the form. TabIndex value will be displayed as a number on each control.
Click on controls in order you need them to be tabbed. This will set appropriate values for TabIndex of controls.
After you finished, go to View menu and turn-off Tab Order.
Select controls you don't want to be tabbed and set TabStop = false.
One simple explanation is that you lost a control underneath another one that overlaps it. Or it is located beyond the edges of the Form. A good tool to find it back is View + Other Windows + Document Outline.
If that doesn't help then diagnose it by adding a Label and a Timer. Write the Tick event handler like this:
private void timer1_Tick(object sender, EventArgs e) {
if (this.ActiveControl != null) label1.Text = this.ActiveControl.Name;
}
You should try the following code:
foreach (Control ctrl in this.Controls)
ctrl.TabStop = false;
Also you can try to check the last tabindex. Then go to your form.designers.cs and find all controls with a greater tabindex and then remove them : add
ctrlTabStop = false;
I did not test any of this, so be careful : backup your *.designer.cs before.
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've come across the strangest bug pertaining to DataGridViews in Windows Forms.
I have a TabControl, that is supposed to contain a docked DataGridView in each tab page. I thought it would be convenient that the grid is focused upon changing the tab page, so that the user could simply hover the mouse over the grid and start scrolling when he changes the page. So, I just put a grids[tabs.SelectedIndex].Focus() in the event handler for changing the tab page.
However, something really strange happened. In my test application, I have three tab pages. If I try scrolling the grid right after starting the application, it doesn't work; I have to click in the grid first. I was expecting this. However, if I change the tab page, I can't scroll in any of the other grids until I click, except for the first one!
So, if I switch pages to the second page, then back to the first, I can automatically scroll that grid without clicking, but if I then switch to the third, I have to click for the grid to focus.
I had a look at the CanFocus properties of the grids, and it seems that only the first grid has it set to True. They are all created programmatically, and all in the same way. I don't see why they would be different.
Any ideas?
Inactive tab pages have their Visible property set to false. The documentation for CanFocus says:
In order for a control to receive
input focus, the control must have a
handle assigned to it, and the Visible
and Enabled properties must both be
set to true for both the control and
all its parent controls
Well, I solved it. Stupid programming error on my part, I had grids[tabs.TabIndex].Focus() instead of grids[tabs.SelectedIndex].Focus().
Oh well.
UI is created in VS 2008. I'm using C# .... I need to let the user move/focus between text fields from top to bottom by clicking tab button. How can i do it?
On the Layout toolbar (will normally show up if you're in Design View) click on the buttom on the most right (it's called tab order).
Now on every element on your designer will come up a little box with a number. Just click all your elements in the order you like and they will automatically be re-ordered.
If you like to do it manually, just take ho1 advice and change the property manually.
You just set up the TabIndex property properly, so that it's sequential from top to bottom. Then it'll work automatically and you won't need any code to move around the focus.
So in other words, set the top TextBox TabIndex to 1, the next one you set to 2 etc and then one at the bottom will have the highest number (of the textboxes, you probably want to have even higher indexes for any OK buttons and similar so that the user can jump to them after editing all the textboxes).

Is there a way to set the visibility of a single tab in a tabcontrol? I thought something simple like this should work, but does not seem to to anything.
tabControl1.TabPages[1].Visible = false;
tabControl1.Refresh();
There will be a main tab that always shows but I want to have other tabs that I can "turn on\off". I don't want to remove the tabs since I may need to show then again.

Times haven't changed since 2.0:
StackOverflow - How to hide TabPage from TabControl
You can remove the tabControl page
this.tControl1.TabPages.Remove(this.tControl1.TabPages["tabPageName"]);
It's obviously not part of the standard Windows Forms library, but the Infragistics UltraTabControl has (among other features) a Visible property for each tab page.
