A true IP address control for windows forms

Some days ago, I was asked by a visitor if it is possible to edit an IP address in Smart PropertyGrid with a specialized editor. The short answer was no. But then I realized that the FieldPackEditor would make a wonderful IP address editor. So I derived a new editor from the base class, created special IpAddrSegmentFieldPack and IpAddrSegmentField classes and voila! Like with other field pack editors, you can show updown buttons, handle a null value, have fixed-width fields or not, set the Text [...]

A new year begins for VisualHint

Yes, this is like a new year beginning here. I was in vacations in France during three weeks for a break from VisualHint, with family in Normandy by the sea not far from the american cemetery for those who know this place. This was very relaxing and the kids had a lot of fun with the beach activities (when one lives in Montreal at four years old, the sea is something new). Now that I'm back, this is time to take stock of the VisualHint's future. So how is it going here you will ask. Here is the [...]

More about null values in a DateTimePicker

Before releasing version 1.0 of Smart FieldPackEditor.Net I must ensure that the support for null values is really complete. So what does this feature really involves? First let’s remind in what contexts a DateTimePicker can operate: It can be a standalone control and completely encapsulate a DateTime value. You can manually bind one of your properties to the component’s Value property. You can embed the component in a container like the DataGridView. In this case, the component will be [...]

Right To Left languages support in Smart DateTimePicker acclaimed!

Even so Smart FieldPackEditor.Net is still in early beta, I received this week-end a message from a developer working at a big israelian company about the support for Hebrew. Here is an excerpt: I examined the control and let me tell you it is very professionally designed and implemented; way to go! Also the RTL and Hebrew are working great, a feat not easily performed by many professional companies. Supporting RTL is something new for me and when I designed the component I even hadn't the RTL [...]

PropertyGrid, SelectedObjects and the property cloning syndrome

Time permitting, I sometimes haunt the newsgroups and developer forums to help when the PropertyGrid is involved. Last week, a poster noticed a very subtle issue concerning .Net 1.1 and .Net 2.0 and I decided to know more about it. It appears that the MS PropertyGrid behaves differently in these two versions of .Net. Here is an excerpt of the original request for help: ... When there are multiple objects selected, and an object property value is changed in the grid, it is assigning the same [...]

Screencast 4: a FieldPackEditor is not just for dates and times

To conclude this series of videos, I'll show what can be done with the editor base class. Everything is inside to handle a set of packs and fields which can edit any predetermined data. And since a field is pretty abstract (after all, this is just a rectangle in which we can draw), I'm sure that some nice scenarios will appear after the product is released. Anyway, here is the show: If there is no last minute drama, the beta will be available next week. If you want to be informed, simply [...]

Screencast 3: Databinding and the DataGridView

In this third video, I show several features of the FieldPackEditor: how flexible it is to bind a DatTimePicker to a data source, how independant field packs in the same editor can be bound to different sources and how the editor can be used in the DataGridView as a perfectly well integrated inplace control. Keep in mind that this editor will also be compatible with Smart PropertyGrid.Net and integrated in place in its value column. [...]

Solving all the issues of the DateTimePicker inside the DataGridView

Some days ago I came across a blog showing the trials and tribulations of a developer trying to display and use the standard DateTimePicker in the DataGridView. This story is really typical of all the considerable efforts one have to make in order to get a semi-viable solution. So far I was not even considering touching the DataGridView. It was an unknown component to me and I was not aware of its extensibility to enable custom editors to be used in a cell. After readind this article I jumped [...]
