When I click it I get the generic collectioneditor. Of course the Add put fails because my collection is strongly typed. I need an example of how to create a collectioneditor that will create my collection's objects.

.net - Setting ReadOnly Property In PropertyGrid Sets All Properties Readonly?
Jun 12, 2012I am using a PropertyGrid control to edit my class properties and I am trying to set certain properties read-only depending on other property settings.This is the code of my class:
Imports System.ComponentModel
Imports System.Reflection
Public Class PropertyClass[code].....
This is the code I am using to edit the values:
Dim c As New PropertyClass
PropertyGrid1.SelectedObject = c
The problem is that when I set SomeProperty to True, nothing happens and when I then set it to False again it sets all properties Read-Only.

VS 2008 Items Collection Cannot Be Modified When The DataSource Property Is Set
Feb 13, 2010I have two tables "Person" and "Alias" in a one to many relationship. I have a DGV for "Person" and want to use a combobox for the Aliases. I also have a textbox and a button for the user to type the alias name and click the button to add the alias name to the combobox and update the dataset. I keep getting the "Items collection cannot be modified when the DataSource property is set." Error. But if i use a DGV instead of a combobox for aliases, I have no errors and everything works fine. If I remove the datasource property for the combobox it will not get populated with the data already entered, so how, or can I, set it up where the combobox gets populated when the form loads and able to add items to the combobox????

Sep 18, 2010When I try to use the following line of code:

details I am connecting to an Access database and using .net 3.5 and writing the code in VB.

Nov 19, 2009I need to create a user control which can be used in my all projects. I have created a user control with a TextBox Control and a ListBox Control. My goal is that as soon as any character is pressed in the textbox, Listbox's item which starts from that character should be selected. I have done all the coding needed for the functionality but my problem is that when I add this usercontrol to my form, I should be able to change the DataSource, displaymember and valuemember properties at designtime. But I cannot see these properties when I add the control on the form.

Datagridview Bound To A Datatable Setting Its Datasource Property To The Datatable
May 20, 2011I have a datagridview bound to a datatable setting its datasource property to the datatable. I would like to have a child form that contains a list of columns associated with the datatable that contains a checkbox that will allow the user to hide and show the columns ( I do not know the best control to use here) (I assume this is the easy part as All i need to do is loop through each of the datatable's columns to get the column name)

Dynamically Add PropertyGrid To Form?
Mar 15, 2012I 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 Scroll Not Working?

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 load an instance of this class with simply ...

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>
