Textbox showing wider in Vista.
Hello all!
We have 2 TextBox controls in a group box in our WinForms application. In XP
everything displays correctly but in Vista the TextBox's right side is off
the right side of the groupbox so we cannot see the right edge of the
TextBoxes.
Also, we have a similar problem with Radio & Checkboxes in GroupBoxes. In XP
the GroupBoxes all display correctly but in Vista the GroupBoxes ...

Context Menu with Treeview Node
I have a treeview with some nodes having the contextmenu property set to
point to a context menu item within my application. There is just one menu
item in the context menu, "Delete". Everything is fine so far and it
displays and works as expected. However, once a treeview node is selected
and then I right click and select "Delete" from the context menu, there
doesn't seem to be any way ...

Standard Control Locations on a Windows Forms Form
I have a groupbox I am creating programmatically ... I add textbox controls
to the groupbox. There is a user-defined number of rows and columns for
these textboxes so the groupbox grows in height and width (as does the form)
depending on the total number of textboxes added to the groupbox. My
question is, when I create the GroupBox and TextBox controls, what location
should I place the...

OnResize()
Hi,
Two quick questions:
1) What's the best way to manually fire the OnResize() event of a
control? (for more info, a custom control that derives from
UserControl).
2) I'm overriding OnResize() in my derived class. I've read that I
need to execute base.OnResize() in my overriding implementation, so
that registered delegates receive the event. Beside the extra stuff
that I execute in my o...

Set focus to first column when adding row to DateGridView
This seems like it should be simple, but...
I have a DataGridView that is bound to a list of business objects. The
value of the first column changes the the available values in a combo box
contained in the row. Using cell validation, I can prevent the user from
leaving the first column until a valid value is entered.
What I can not figure out is how to set the current cell to the fir...

Datagridview - keeping last row visible
I have an application that watches a file and as the file grows, adds
rows to the end of a DataGridView. The idea is that the most recently
added row should be visible and the DGV scrolled to ensure that.
Unfortunately, the DGV doesn't have a property that accomplishes this
directly.
Instead, I walk backwards from the last row calculating the row's
height (using Graphics.MeasureString...

DataGridView.ScrollBars = None auto-scrolls when columns resized.
I am replicating Excel's splitter arrangement, which has led me to
implement my own scrollbars. Unfortunately DataGridView resets the
scrolling positions whenever a column is resized. I can reduce this to
a very simple example:
1. Drop a DataGridView on a form and add a bunch of columns.
2. Set ScrollBars = ScrollBars.None.
3. Programmatically scroll the grid to the right.
4. Resize ...

Composite User Control and Custom Designer with Container for WinF

Everything works fine, especially the Drag & Drop operation.
Just one question regarding the AutoScroll function. It appears to me that

Hi Group,
I was asked recently if I knew of a way in which a ContextMenuStripItem
selected by keyboard press could be forced to ScrollIntoView if it were
currently not in view. To be honest I hadn't really really looked at this
class and so wasn't aware of it's limitations. I had a look at it this
morning and found that it was surprisingly lacking. There is no SelectedItem
property an...

COM Calling DotNet
I am unclear about what all the requirements are to call a simple vb.net

I believe I have installed the dll in the GAC. It is in there and has a

named, as it shows up in the GAC.
How do I browse the objects of it? I ...

Always display "Dropdown" arrow in PropertyGrid
All,
We are trying to use a PropertyGrid to display a custom class to our
users. Things are working well; however, some of the users have a
complaint.
Some of the properties are Enumerations (ie, the user would pick an
item from a predefined list). When the user selects one of these
properties, they get a combobox and can select an item. Some of the
users (unfortunately, the "importa...

is in the constructor). After the height and width is set, is there a way to
