After using C# a while, I recognized that the user controls of system windows forms don't provide a tooltiptext property like I am knowing it from Visual Basic 6.
I saw that the Form, TextBox, Label, ComboBox and PictureBox don't have such property.
Now I have the curious question:
How would I display a tooltip to the user on mousehover over a control like the above mentioned?
And Yes, I saw the "tooltip" control in the toolbox. It provides a baloon and I do not need a baloon.
It shows the tooltip for one item only once per user session and then never (known problem of the component) and why I would need an extra component, if this should be just a property of the corresponding control, for which I would like to provide a tooltip like TextBoxes, Labels etc.
And Yes, I saw the "Help Provider". I have usually never a help file assigned with my projects,
so I do not use the Help System. What I need is a simple Tooltiptext, not a "F1 component".
Now I am curious, how I would implement a Tooltiptext if the controls don't provide a option for it.
Can it be, that C# has no control tooltips? Even Delphi has! Or have I missed something somewhere?
The solution:
Delete all notifyicon controls from your project to ensure no unwanted info bubbles appearing
in the system tray.
Drag and Drop the Tooltip Component in Toolbox on your form, but ignore all the baloon properties and the baloon timeout properties and baloon timer properties, just Drag and Drop
the component without further action.
A weird new property field "tooltip on tooltip1" shows now up in all TextBoxes and Labels etc. on the form.
Just handle this field as it would be your Tooltip property and don't setup anything else in code
or on the designer. Build and compile. The tooltiptext will now show up as normal tooltip without
baloon functionality.
It sounds like you are using the ToolTip control incorrectly.
1- Drag it from the toolbox to your form.
At this point, each control on the form now gets a property "Tooltip" to set the appropriate text.
2- Set each control's new "ToolTip" property in the way you find most intuitive.

I am working on a project in which I am using a property grid to display the properties of the selected control.
The Property Grid is fixed to the left edge of the container and in the rest of the space I have the form I am designing.
On clicking a control on the form, the specific control’s property is getting selected.
In the above figure, I have selected the textbox and the textbox’s properties get shown on the propertygrid.
Here if you observe, by default, the Name property is highlighted as well.
Is there some way to unselect this property programmatically?
I have tried some suggestions online but none have helped. I am not able to find find a way to remove all selections from the PropertyGrid, but its behaviour seem to be different form a DataGrid...
Here is why I need this...
On selecting a control, if a property in the property grid is selected, then the property is getting modified.
For example, If i cut the control using Ctrl + X, the selected value in property grid is getting cut which in some cases is forcing user to set the property before modifying anything on the form.
I have tried selecting multiple controls, but in that case alse the selected property seems to be persistent
Since PropertyGrid uses DefaultProperty to select a property in its grid, as an option you can set DefaultProperty attribute at run-time for your object to a non-browsable property, for example:
this.propertyGrid1.SelectedObject = null;
TypeDescriptor.AddAttributes(someControl,
new Attribute[] { new DefaultPropertyAttribute("Site") });
this.propertyGrid1.SelectedObject = someControl;
Well, what you are trying are hacks. It is never a good idea to do such hacks particularly if you are not the only person that use the software.
In your case, the focus should be on the designer while you interact with it. So if the user press Ctrl+X, the designer should respond to the keyboard and it should not have any effect on the property grid (as only one control can have the focus at the same time).
Thus it is up to you to make sure that your designer is focusable, that it has the focus when initially displayed, that it get the focus when you press the TAB key. Pressing the TAB key again should put the focus on the property grid so that user can interact with the grid without using the keyboard.
If you have more than these 2 controls, then obviously TAB should also stop at any appropriate controls. Also, it can be a good idea to have some direct shortcuts like F4 to (show and) activate the properties pane.
If you are not able to make it works, then the best compromise would be to use another windows for the properties grid. By using a distinct Tool windows for the properties, it should not respond to the keyboard when the main windows has the focus.
Here are some links that might help you:
Panel not getting focus
Control.Focus Method() — See Remarks section.
In any case, you should not prevent Ctrl+X to works as expected when the property grid has the focus and a property is selected. Users don't like software that do not follows UI conventions.
As a software developer, you should as much as possible ensure that your application follows standard behaviors. I recommend you that you take one or 2 extra days developing your software properly instead of doing hacks.
Often, compromise to gain a few days will never be fix and will be a pain for many years. Better to do it right from the start. Unselecting an item in the property grid is not an acceptable workaround. Your manager should not allows you to do that.
In my wpf window I want to change part of it (make different controls visible) when combo box selection is changed. Exactly like TabControl works, just with combobox. I know I could just make some controls visible while hiding the others in the c# code behind but I want to find out if there are other -better solutions.
You can use two Grid or GroupBox (or other container type) controls and put appropriate set of controls in each of them. This way you can just visibility of panels to hide the whole set of controls instead of hiding each control directly.
It may sometimes be appropriate to create a user control for each set of controls. However, this can depend on a specific case.
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'm trying to force Minimize/Maximize/Close buttons' tooltips (in ribbonform) to get a look from a lookAndFeel. So far I created a ribbonform, then I placed defaultLookAndFeel component on it ahd I chose an OfficeBlue skin. My ribbon form changed however the tooltips for control buttons(minimize,maximize,close) look the same. I also tried to use DefaultToolTipControler however changing properties on appearance section didn't get any results.
Is there any way to change appearance of tooltips mentioned before?
You're probably trying to get rid of the Aero integration.
Set AllowFormGlass to false.
I'm working on a custom user control that essentially displays a name value pair (name is on a black background, value on a white). I have my control displaying correctly, even showing up in Designer and on my build page.
What I'd like to do from here is have the ability to right click on the user control and have a menu come up that has a "Copy Value" option, that when selected will copy the value in the "value" part of the user control to the clipboard. What is the best method of approach?
I'm not sure where to start since most of the documentation on user controls I've found deals with displaying the control, not necessarily interacting with it. Additionally, since I'm still learning C#, I might have left out an important part of my problem in this question, so please point that out if it's the case.
I'm using Visual Studio 2008 (if that matters).
Examine the ContextMenu control and the ContextMenu property of other controls. By assigning a ContextMenu control to the ContextMeny property of another control, you will have the right-click->popup menu wiring done for you. Then you only need to implement the click event of the different menu items in the context menu.
Then you can use the Clipboard.SetText (as suggested by BFree) to set the desired value to the clipboard.
Add a ContextMenu to the control. The, hook into the MouseClick (or MouseDown, whichever works better) event and if it's a Right-Click, then call show on the ContextMenu (there are a few overloads, try to mess with them see which works best for you). Then, in the click event of your context menu, just call Clipboard.SetText(...) to set the value to the clipboard.
