I have written a Type Converter for a TrackBar. I was wondering if there is any way to get the value being changed in the Dropdown so I can update the PropertyGrid item value dynamically instead of just at the end?
Here is the Type Converter code:
Code:Imports System.Windows.Forms.Design
Public Class Slider
Private editorService As IWindowsFormsEditorService
Private m_Value As Integer

I need to create kind of a menu in my application in wich I have to set different parameters before I populate a Datagridview with some values.So, the idea is to use a PropertyGris in which from which I can edit some parameters and after that I run a query (with parameters setted by PropertyGrid) tu populate my DGV.For example I create some properties like NAME OF A PROJECT, ID OF PROJECT, RESPONSABLE, etc and I put this properties in a propertyGrid and than the user can interact with the propertyGrid and set value for each parameter, bfore running the query for populating

i'm hoping to use a propertygrid in one of my programs.
1/ i'm having difficulty writing a (text) property that will open a multiline editor like the textbox text property in the vb properties window. how would i do that?
2/ i need a way to make either selected properties or preferably entire categories disabled or enabled at runtime.
3/ how can i turn off automatic sorting so my categories + the items they contain are displayed in the order they are in my class?

I want to add a new PropertyGrid control every time an item is added to a ListBox.I have a ListBox, with an "Add Item" button underneath (and also a "Remove Item" button). Every time an item is added to the list, I want to create a new PropertyGrid corresponding to each item. The relevent PropertyGrid should appear when an item is selected in the ListBox, and the user can edit the properties of that item.
The only way I can think of doing this is by creating a dynamic array which has length ListBox1.items.count, but I'm not sure it's possible to create an array of controls.

PropertyGrid is only scrollig correctly when I place it on a Windows Form, but does not work when it's docked in a SplitContainer Panel. Only the vertical scroll bar is needed for my application. The vertical scroll bar displays correcly and you can move it up and down okay, but the contents of the PropertyGrid (while correct) do not scroll up and down with it. I'm using Visual Studio 2005 Professional Version 8 with .NET Framework 2.0 and coding in Visual Basic. Has anyone found a way around this?

I would like to display a PropertyGrid on a form at runtime to simplify some testing that I am doing. I have it working except that the PropertyGrid does not pickup any extender provider properties (eg ToolTip). How do I make it aware of any extender providers also?

Using <System.ComponentModel.TypeConverter(GetType(System.ComponentModel.ExpandableObjectConverter))> _
on the declaration of a class (which is a property of another class) that consists of a number properties.
I load an instance of this class with simply ...
PropertyGrid1.SelectedObject = oColumn
Obviously I don't want to manually build the propertygrid in code, I know how to do that.
But here's the problem. Depending on the value of a property, certain other properties should not be visible, as though I'd used the <System.ComponentModel.Browsable(False)> _
attribute on the property declaration.Is there anyway to do this programmatically, without having to handle all the building of the property grid manually>

I'm trying to add a custom DropDown to the PropertyGrid for a control. I am adding the TrackBar control.It works fine, except, I would like to have the values updated in the PropertyGrid as I move the TrackBar. As it is now, it only updates the PropertyGrid when I finish and click off the TrackBar.I know the problem lies in the Type Editor. How can I get it to allow interim values to be processed. Is there some callback function I can use?

I am having a problem with objects that have other objects as properties on a property grid. Now when I display the object clsPropsFrame on the property grid, everything shows up as expected, except when I try to edit the x, y, or z of location which is of type clsPropsVec3, it ignores the change. What's strange is that when I type the vector in as a string (like "0, 16, 0"), it changes.
I have the following
'//////////////////Object Component///////////////////////////
<TypeConverter(GetType(ExpandableObjectConverter))> _
Public Class clsPropsVec3
Inherits ExpandableObjectConverter
Private refvec As TV_3DVECTOR
Public Sub New()
[Code] .....
I noticed that when I changed a component of clsPropsVec3, the property change in clsPropsFrame does not get executed. I tried making it fire of an event when a component is changed in clsPropsVec3, with the following additional
Public Property X() As Single
Get
Return refvec.x
End Get
Set(ByVal value As Single)
[Code] .....
But for some reason it ever fires off the ValueChanged event. So how can I make the sub properties of clsPropsVec3 work?

Within my PropertyGrid I have decorated a class with the following attributes:
Code:
[Category("Category 1"),
DisplayName("Part Number"),
SortOrderAttribute(1)]
Dim PN1 as String
[Code]...
The problem is that when PN2 is changed in the PropertyGrid, it causes a refresh of all cells. Since both properties have the same DisplayName, but different Categories, the focus is set to PN1 and not PN2 after PN2 is edited.

I've been following this article:and have everything working.Under the Support for Custom Types section, it introduces a collapsable type for the spell check options. The option are added together to produce a string that is displayed in the grid in the Spell Check Options row. Is it possible to get this string directly from the 'AppSettings' class or do I need to add another property and copy the code from the ConvertTo and ConvertFrom functions?

I have a list box on the form which functions as a copy/paste. When you copy something, it is automatically added to the list box as a "clipboard helper". Here is the problem,however: if the text is more than 1 line, the list box does not show all the text.It ends up looking messy.So getting back to my question, is it possible to make the list box item height for an item depending on the amount of lines that item contains?This is a one line sentence in the list box and should take up one line.This is a multi line sentence in the list box and should take up two lines for item height.
