I got an application that the main form contains a System.Windows.Forms.ToolBar.
I want to add a new System.Windows.Forms.ToolBarButton with a little longer text from the rest. so on the designer window when I press Enter after I changed the text, I see part of it with 3 dots (...) and when I click OK, the toolbar itself gets very wide for some reason and the spaced between every item gets bigger.
I couldn't find a lot online about this control... maybe it's old but I can't change it.
I tried to access the buttons but when I drag, the whole toolar mooves.
What can I do ?
Thank you very much !!

I don't understand why when a new form opens, one of the buttons is highlighted in blue.
How can I fix that?In the picture you can see the problem, it's happens in every Form
Without code, I suspect that the highlighted button is the last one that you placed onto the designer and this will leave it as the default control in focus.
It's usually good practice to set focus, visibility, enable and tab order controls manually if you want them to be something specific.
I'm currently trying to create an image previewer in my program, which I'm doing by creating a UserControl. All seems to be working great, except that I now would like to move some of my buttons to the top of the UserControl.
I have done this by creating a ToolStrip and adding two buttons and a combobox. My problem is, that the new ToolStrip (toolStrip1 - see Document Outline pic.) won't show when I run my program. I have tried settings toolStrip1.visible = true and using the .BringToFront() method, but none of these options seems to work.
Can someone help me solve this irritating problem?
P.S. toolStrip2 is showing just fine in BottomToolStripPanel.

Picture 2: My Image Previewer Design. The top bar is toolStrip1 which I'm currently not able to see when I run my program.
I've quickly duplicated your layout, and it worked without a problem here.
Do you not by any chance set the "TopToolStripPanelVisible" property on the "toolStripContainer" to 'False' programatically?
this is my first thread on this great website for programming :)
I have a problem with my UC. I'm currently developing an extended version of DataGridView, which added some functionality like paging support.
Here is the picture of the UC inside a form, after I make it bigger than the initial size:
And finally, I change the form's language to Indonesian. And then the designer suddenly repaint my UC. The size of the container of my UC is OK, means the designer remembers that I resized my UC before. But unfortunately the controls inside the UC's container gets switched back to their initial size, leave some blank spaces inside. This behaviour only happen in design time. The UC is fine in runtime mode, its size works well.
How could this happen guys? Although it's fine in runtime, but it's ugly in design time.
Sorry for my English, greeting from Indonesian :)
Thanks.
===SOLUTION===
After play a bit, finally I've found the solution. Before I place the controls inside to the container, I must first add a Panel to the container, set it to transparent, and set its Dock property to Fill. Then followed by DataGridView and BindingNavigator to the rest. Build and it works like a charm!
It seems that the Panel resolves the problem :)
Cheers
Maybe it will help to change the order of the factors. First change the Form language to Indonesian. Then save your project and close it. Open it again and check if it still on Indonesian then place the DataGridView control on the form and re-size it.
I have a program that loads a tab that has roughly 332 text boxes it loads. When loading a new tab there is a 2-3 second delay before the tab can be displayed. I have tried to suspend and resume and even looked into threading but found out that a winform can only use one thread.
I was wondering if there was a way to create the text boxes in another thread and then add them into the main form or a way to better create 332 text boxes.
thanks for your help.
Depending on your layout, I'd strongly recommend replacing the textboxes with a DataGridView, or otherwise loading the textboxes on scroll with some kind of continous-control .
The main bottle neck is the creation of handles. In winforms, each control gets its own handle (even labels), and when used in large numbers such as this, can indeed give performance problems.
If a datagridview is not an option, can you give some more information on the layout (a screenshot perhaps?), so the community can have a go at alternatives. Creating the textboxes in another thread will create problems when you try to add them, but you could create them only when needed.
Simple: don't use 300 text boxes. You can only use one text box at a time. The rest of the data you can just draw, and when the user wants to edit it you create the edit control for it. This is exactly how a grid works, so I recommend using a grid or similar control.
I also had this problem, and it goes further to affect initialisation code for controls on tabs that has not get activated before.
My workaround is to block the program with a "loading..." splash and programatically click the tabs so that the controls get loaded/activated. Once this is done, the tabpage shoud not take as long to display again.
Although I agree with others in that you may want to look into reducing the number of controls in a single tab.
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).
