I have a ListBox which contain text and image. When the user click on an Item I want that it will expand to the side and will show some more information.
I have tried to do it with Expander control, but it's does'nt expand over the ListBox border.
Does anyone have any suggestions ?
This sounds like a classic master/detail type of user interface - the ListBox is the master, and you want some detail to show once the user selects an item.
If the tooltip suggestion from Notter is not suitable, then i would suggest that you have your expander control beside the ListBox, not inside of it. There are already a multitude of posts here on SO deailing with this (usually using the DataGrid as the master, but the concept is the same), check out this search and see if anything is helpful.
You can maybe use a Popup/tooltip control (forgot it's name)
other than that, i can't think of anything that will do what you're asking, but i'm pretty sure anything you'll do won't have anything to do with the ListBox itself, but with the DataTemplate

i want to immitate the behavior of multiselection of items (eg. in a list view) and their appearence in a PropertyGrid. So, obly the same properties are shown and values set in the grid are set on all multiselected properties.
I have created a listview with some datatemplates and have in another listview some data(with databinding). Now i want wo have a multiselection on the listview with the data and have the properties shown in the another listview like in a propertygrid.(explanation: The ProprtyGrid is still not available in WPF and if has not the flexibility of showing data the way i need it)
So, how do i need to prepare my data to be shown in the list propertygrid-multiselection-style? Is that even possible???
Greets,

I'm not sure if this question is still active, or what not. But I have found a solution that works for me - and I need somewhere to share it.
The first issue you are going to have solve is selecting the items, ie. multi-select. See my tip here that explains how to do that.
Next, I guess its basically binding to listview's selectedItem property and how you want to update your propertyGrid based on changes to the selectedItem prop.
Hope this helps.
I've got Expression Blend 4 installed on my machine. I just need to know what I'm doing.
My application will be running on a laptop equipped with a touch screen, in police cars where the user will probably be driving the car. Needless to say, the interface has to be easy to use. In this case, that means things like the drop down buttons on ComboBox controls and scroll bars need to be wider than normal so they're easy for the driver to use.
Can someone tell me what part I have to change for each of these controls in order to get the effect I want? I tried editing a copy of the template for one of the combobox controls in one of my user controls and playing with the ToggleButton control but that didn't do what I wanted it to do. There's so much mark-up in the template it's hard to tell what's doing what.
Thanks for any help you can give.
Tony
Edit:
I figured it out from the first answer to this previous StackOverflow post. I had to make a copy of the ComboBox's style, then make a copy of the ToggleButton's style.
Thanks anyway.
Tony
The solution was to edit the application in Expression blend. I clicked on one of the ComboBoxes and right clicked. From the context menu, I selected Edit Template | Edit a copy. In the dialog box that appears, I specified that the new template should be applied to all ComboBoxes in the application.
Within the ComboBox's style, there's a ToggleButton. I repeated the above steps with the Togglebutton. Finally, I changed the width to make it what I wanted. There's also a path in there for the arrow that you can play with if you like.

I am trying to work though the best approach to accomplish the following. Within a page I have it divided into two section. On the left a listbox and the right is empty. (Grid etc). What I would like to accomplish is when an item is selected from the listbox a different user control loads in the right panel. For example if I have three items (one, two three) selecting one would load a red user control, two would load a blue user control and three a green user control.
I was taking this approach since Content Template / Data template selectors are not available in SL. However if anyone has another suggestion I would be grateful for your thoughts.
I'm creating this with MVVM in mind and traditionally I have managed this within the code behind of the user control however I have seen mention of how this could be managed within the ViewModel as well.
Any suggestions or guidance on a best approach is always appreciated.
Cheers
You can bind both listbox selected item and user control visibility properties to the same property in the viewModel.
Then just use a valueConverter for each user control to switch on/off the visibility.
Please tell me if i should elaborate/add a code sample.
I'm trying to achive displaying the RowDetailsTemplate of a Silverlight DataGrid depending on a bool Property, bound to a CheckBox Control's IsChecked Property. Insinde of my RowDetailsTemplate there is a single custom UserControl, containing further Controls.
Since the DataGrid only allows a global setting (RowDetailsVisibilityMode) Some code-behind is needed. I've implemented a solution based on Rorys Reply (and using a behaviour-technique) which actually works.
Unfortunately, The DataGrid doesn't remember the individually shown or hidden Rows on sorting. The checkbox remains selected, but the Row collapses. Further, no event like "OnAfterSort" or something similar seems to exist, where i could "Refresh" the visibility settings in a loop.
Another idea was to bind the Visibility of my custom Details-UserControl to the CheckBox bound value. This actually works (when settings RowDetailsVisibilityMode to "Visible"), but I'm not able to get rid of this weird behaviour: When the CheckBox is checked, the Detail Template expands and the detail UserControl appears. Nice. When the CheckBox is unchecked again, the UserControl disappears (Visibility is set to Collapsed) but the Row doesn't collapse and the blank space remains (as it would be set to Hidden not Collapsed).
Do you have any ideas?
I hope it's ok I didn't post any code samples, the implementation is pretty easy and I believe that the problem doesn't actually lie in a coding mistake i made. You can setup a simple DataGrid quickly like in this perfect MSDN Example. Starting from here, it's easy to test both described behaviours!
Really big thanks in advance,

How can I define different ContextMenus for each column in the DataGrid (Microsoft's grid)? I found out that the grid provides a ContextMenu attribute, but i want different context menu items for the columns, not the same ContextMenu for the whole grid.
Edit: Thanks for your answer! I tried to listen to the ContextMenuOpeningEvent as you suggested which was a first success: the ContextMenu can be modified in the EventHandler. But it raises another (hopefully small) problem - I now have to identify the column the mouse cursor was over when the ContextMenuOpeningEvent was triggered. I'm going to research how to do (or work around) that later.
I haven't played with it at all, so this might be wrong, but you may be able to override the ContextMenuOpening event and create the appropriate menu on the fly.
add menu item to default context menu might give you a starting point.
Good luck.
