This is supposed to be a no brainer but I still can’t figure it out. In my sample app there’s a button and a textbox in a dockpanel. If the content of the textbox is smaller than the content of the textbox the window is as big as it needs to be to display the content of the button. That’s what I want. But if I put more text into the tex...

I have a two-level hierarchy displayed in a WPF TreeView, but I only want the child nodes to be selectable - basically the top level nodes are for categorisation but shouldn't be selectable by themselves. Can I achieve this? Thanks... ...

I'd trying to style my ComboBoxes to match the rest of the UI but I'm having problems with the IsMouseOver highlighting. It highlights with the color I specify for a second and then fades back to the default color, kind of a cool effect but not what I'm going for. Here is my style: <Style TargetType="ComboBox"> <Style.Triggers> ...

I am migrating some win forms panels to WPF. In WinForms, you can tab into to the combo box using the keyboard, select an item by typing the first character and then hit tab again and the combo to lose focus. In WPF the second tab will move the focus rectangle down the list, instead of moving onto the next control. Is there a way to g...
We are starting a new project and I'm trying to decide which of the Wpf-esque develop/deploy strategies we should go with. In our case we are looking at quite a complex business app that will be used by 100s (not 1000s) of people, So I'm leaning towards a click-once app. My boss likes the idea of a Silverlight app as it means easier depl...

I have a WPF control, that has a list of "Investors", and in the right column of the list, a "Delete" button. I could either waste some time making an image of an "x" in photoshop. Or, I could just use Wingdings font and set the content to "Õ" (which makes a cool looking delete button). Is this appropriate? My thinking is... while not ...

I'm writing a mapping app that uses a Canvas for positioning elements. For each element I have to programatically convert element's Lat/Long to the canvas' coordinate, then set the Canvas.Top and Canvas.Left properties.
