Tab index with tabControl - c#

I have a tabControl control with multiple tabs. For each tab, I am adding tab index arranging the controls from top to bottom.
However, when I click tab during the program the order that the program moves from control to control isn't the order I specified.
Does this have something to do with the tabControl?
I am using the "tabIndex" property for each control.
Edit: Sorry I didn't know about this function, here is what it shows:

The red arrow is the flow the tab makes.

With TabOrder tool active, first click on each container controls (eg. the groupboxes) then, if the controls order inside the groupboxes, is not correct, click on each control in the order you desire them.
You will see the number change accordingly to your clicks. Sometimes happens to click in the wrong order, in this case close the TabOrder tool and reopen to restart again.

Unable to edit form using DevExpress

puu.sh/kiQ0k/aa28192731.png
Does anyone know how I can manipulate the objects in this form? I would really like to be able to edit some of the tabs. It's using DevExpress v14.1
To edit the tabs, just click the tab control and use the design time helper icon on the tab controls upper right corner. There, you can find a link called "Tab pages".
Alternatively you can just select the tab control by clicking and head over to the properties window (press F4) as you can do with every control. There, you find a property called TabPages.
If you want to edit the controls on the tabs, just do so by selecting them per mouse click and change the controls' properties on the properties window (press F4).
The issue was that DevExpress wasn't installed on my system and thus wouldn't let me modify the elements. Simply installing the right version fixed the issue.

select buttons orderly in userControl by press Tab key

I have a UserControl with some buttons in it (btnNew, btnCancel, btnEdit).
I used this UserControl in another project. When I press the tab key in this project, the selection button doesn't change regular!
For example, I want that if the user presses the Tab key, first the btnNew button is selected, then the btnEdit button, and finally the btnCancel button.
But in this project, when pressing the Tab key, the btnCancel button is selected first.
I want to manage the tab order of the buttons myself, and not use the default. How can I do this?
Thanks...
To set the order of how the buttons will be selected on tab press use the property
TabIndex
it defines the order the tabs will be selected. So set the tab index like the following
btnNew.TabIndex = 0;//selected first
btnCancel.TabIndex = 1;//the second
btnEdit.TabIndex = 2;//the last one
When the form designer is open go to View > Tab Order this will allow you to set the tab order in a very simple and easy way.

I don't have much knowledge on Windows Forms, As I know there will be a TabIndex property for each control.
You can set your order using that.
Menu View-> TabOrder
or
manually set TabIndex for each control.
To set the tab order of a control
On the View menu, click Tab Order. This activates the tab-order selection mode on the form. A number (representing the TabIndex
property) appears in the upper-left corner of each control.
Click the controls sequentially to establish the tab order you want.
When you have finished, click Tab Order on the View menu again to leave tab order mode.
Quoted from here.
You could also change the TabIndex property of each of the controls individually in the Properties pane. Or change it programatically like so btnNew.TabIndex = 0;.

Keep Label on top of TabControl .NET

I have a label that I need to stay on top of my TabControl as I switch from tab to tab. I have tried calling the Label's BrintToFront method in the SelectedIndexChanged Event of the Tab Control but this has no effect. I also simply tried right clicking my label in design view and selecting "Bring to Front" but again, this had no effect.
When I switch to my second tab it drops behind the TabControl however, when I go back to my first tab it is in front again.
I placed the label itself on the Form rather than on the TabControl.
I am working in C#. Any ideas would be greatly appreciated. Thanks.
You should make sure that your label is not located inside a specific tab. To verify this you need to look at the nesting inside the 'document outline' (ctl+alt+T)
If it is I recommend;
dragging it just outside the tab control (you can also use the document outline).
then 'bring it to the front'.
and then use the arrow keys, or location property, to move it back into position.

DataGridView cannot be Focused, but one of them can

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.

How to Set Up Winform Textbox Field Focus so a User Can Go Through Them by Clicking Tab Button?

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).
