In my windowsForm application I use a PropertyGrid to edit the instances of my class: some of these properties are floating point with maximum and minimum item.
I wish modify them by a slider or something like it.
I've found this: http://www.visualhint.com/propertygrid but is not free..
do you have an idea to help me?
You can make use of TrackBar. Note that PropertyGrid by default does not allow you to add controls like these to it. So, you will need to do some work here. You will need to create a class that inherits from System.Drawing.Design.UITypeEditor. Next you will have to set the editor attribute for the property that has to display track bar as control. Note that unless you do custom paint, it will be shown as modal dialog or as dropdown editor.

i used PropertyGrid control to display properties on gridview.
i have taken an reference of this link http://www.c-sharpcorner.com/article/using-property-grid-in-c-sharp/
which is showing like this
But i need checkbox just before the property name shown in red mark on check/uncheck for any property i need to build expression.
I recommend reading this: How do I change boolean properties with one click in PropertyGrid.
It extends the PropertyGrid control and defines its checkbox controls using UITypeEditor.
As Reza mentioned, your choice of control does not appear optimal. You should probably create a form with TextBox, CheckBox, ComboBox etc. Or make use of DataGridView if your display is catering for multiple records at same time.
If you most definitely want to customize PropertyGrid, here is my another answer which might help you start with.

I inherited the CheckBox class to design a custom user control and I would like to specify the same icon image for my toolbox item like the default image that is shown for the Microsoft's WindowsForms CheckBox toolbox item.
To understand what I mean:
I think this would be possible using the ToolboxBitmap attribute, however I'm in the need to provide the assembly that contains the user control without additional files, so I can't use a local filepath to specify a custom image and the overload where lets you specify a Type/Assembly and what it seems a resource name I really don't know how I should use it.
Or maybe specifying the proper value in the ToolboxItem or the Designer attributes, however, I don't know how to do so.
If necessary, I know how to obtain the default checkbox image by downloading the Visual Studio Image Library but once I have the image and after adding it to the resources of my assembly I don't know what to do with it and with the ToolboxBitmap attribute.
This is the code I have done to get an idea, the commented lines are just things that I'm testing randomly to try solve this issue:
'<ToolboxBitmap()>
'<ToolboxItem("System.Drawing.Design.ToolboxItem, ???")>
'<Designer(GetType(CheckBox), GetType(IComponent))>
<DesignTimeVisible(True)>
<ToolboxItemFilter("System.Windows.Forms", ToolboxItemFilterType.Require)>
<PermissionSet(SecurityAction.Demand, Name:="FullTrust")>
Public Class ElektroCheckBox : Inherits CheckBox
End Class
PS: Please note that I have the same need to accomplish for other user controls that does not inherit from CheckBox class, so an extended help would be very gratefuly from my side if I can understand how to do the same I mean how I can specify for my toolbox item the default image of other controls like for example a Listview or a Listbox.
I need to know how to create a property in my user control like font property in textbox control.
That property should open a dialog box to place different values.
You can do this, but it requires lots of bits.
The walk through is here, but since link only answers are not always useful, here are the highlights.
Create a view control for the editor
Derive a custom editor class from the UITypeEditor
Override the GetEditStyle method to use your custom editor class
Override the EditValue method to wire up the custom editor to the property value
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.
Maybe its something stupid, but I'm having a problem with a subclass of a DataGridView Control in VS2005 C#. I know I can subclass from almost anything by doing
public class MyDataGridView : DataGridView
{}
no problem, and I put in some things / elements I want applicable globally. Now, I take this gridview and put into a custom user control that will contain other controls too. So I have something like created by the visual designer. I grab some buttons, label, and my derived "MyDataGridView" on it.
public partial class MyCompoundDGVPlus : UserControl
So, now, I can visually draw, move, change all sorts of settings as needed, no problem.
Now, I want this "MyCompoundDGVPlus" class as the basis for other classes, of which I will manipulate settings specific, but want all to have the same look / feel, and otherwise similar flow, hence the derivations.
I've even set the "modifiers" setting to public, so I SHOULD be able to modify any of the properties of the controls at any derived level. So, now, I create a new subclass of "MyFirstDetailedDGVPlus" derived from "MyCompoundDGVPlus". Ok visually, all the label, button, datagridview appear. However, now I want to specifically define the columns of the datagridview here in this class visually, but its locked. However, the LABEL on the form, I CAN get all the property settings....
What am I missing.
Maybe you should take a look at this post as it seems to do what you are looking for :
