阅读更多关于 PropertyGrid PaintValue issue: How to remove (and paint outside) the standard rectangle?

问题 This might be a straightforward question, even though I haven't found an easy solution to it: I've implemented my custom UITypeEditor with the sole purpose of adding a PaintValue to bools. For the sake of the discussion, let's assume that PaintValue will either paint a checked or unchecked radiobutton. Question 1: Now, here's the problem: It seems like PaintValue automatically inserts a 20x13px rectangle after all paint code has completed. Naturally, a radiobutton inside a black rectangle is

But how do I disable editing of the selected item directly, readonly option prevents it from getting edited. Let's say I'm changing a Property Country from another form which displays a list of countries in a listbox. When I select 'Algeria' and press OK, 'Algeria' is displayed across Country, but I can directly edit Algeria to any other value,

问题 I've created a custom UITypeEditor. Can I possibly insert an attribute that also attaches a TypeConverter to my property from inside the UITypeEditor class? I've tried the following, but nothing happens, no matter how I twist and turn it: Attribute[] newAttributes = new Attribute[1]; newAttributes[0] = new TypeConverterAttribute(typeof(BooleanConverter)); Now, the above needs to have the following attached to it somehow: TypeDescriptor.AddAttributes(context.Instance.PROPERTYNAME,

How can I override behavior of DockStyle Editor in PropertyGrid

阅读更多关于 How can I override behavior of DockStyle Editor in PropertyGrid

问题 We have a custom panel which inherits Panel and has an Orientation property implemented similarly to the SplitContainer Orientation property. For our custom panel, DockStyle.Fill is never valid and depending on the Orientation property value, DockStyle needs to be Left or Right for Vertical or Top or Bottom for Horizontal. The DockStyleEditor class is sealed so we can't subclass it for our own custom UITypeEditor. Is there a way to override certain behaviors using a TypeDescriptor or some

In case I make no sense here a mock of the form: . My problem: To fill the listbox I need access to the

How do you hook an editor for TFS 2010 WF BuildProcessTemplate arguments for built-in types that have a converter?

I've followed the Team Foundation Server 2010 book 's custom editor for a dictionary<string,string> and can't get it to go. I have another custom editor in the same assembly, and consumed by the same build template that works. This SO hints at it being a TypeConverter issue, but I don't think any part of a custom build assembly is just run when it is loaded. I'm getting the default generic Collection Editor instead of mine.
