I assume it has something to do with my inheritance. I have a usercontrol called AbstractPage (i...

I would like to increase the space between rows, but setting the DividerHeight in the RowTemplate has no effect. Does anyone know how to increase the space between rows when the AutoSizeRowsMode is a value other than "None"? Thanks! ...
I'm modifying a windows form to allow data to be loaded in the background while the UI remains responsive. The data takes noticeable time to both retrieve and bind. Ideally, I would do both in the background, but there is some ambiguity about what kind of UI updates I should be doing in the background (as in outside the main thread). ...
Whenever I want to modify a winform from another thread, I need to use ->Invoke(delegate, params) so that the modification occurs in the winform's own thread. For every function that needs to modify the gui, I need another delegate function. Is there some scheme which allows me to limit the number of delegate functions needed? I have...
I have a VB.NET (2005) application designed by my boss that uses a over 100 input and display controls (textboxes, comboxes, etc.), many with labels associated.

I am actually finding that chkContactType.Items is empty when I step through the code. I even added a Watch to chkContactType.Items.Count and it is never anything but 0. I am severly confused now as it obviously isn't as my Insert method works fine which uses these same boxes and inserts the Value Member for each item.... I have som...

I made a custom control that is basically a multiline TextBox that allows input, and some other controls on the side that report some information. Now, I wanted to allow the user of my control to change the font in the TextBox, and thought something along the lines of: "Well, the user shouldn't be able to change the font of other control...
I'm working on an application, and I have a screen that in my mind, looks a lot like the Wireless Network List in Windows Vista. For those who are unaware, its basically a listview, but in each row, instead of a line of text, there's a large 'panel' that contains all sorts of useful information. Does anyone know if that's an actual UI ...

One text box, a combo box, a list box and a couple of command buttons are anchored so that they resize with the form. The combo box is anchored to the left, top and right, the listbox is anchored on all four sides a...

The tables can be big and I use DataBinding to connect the tables to the DataGridView. When I close the form, I notice that the memory taken by the form is reclaimed timely. I use the normal way of ...
