How do I hide a row in a WPF grid?

- by elggarc

I have been hiding a row in a WPF grid by setting the Height property to 0. I was expecting something akin to a Visible property. Is there a more appropriate way to hide the row? Thanks, E

What techniques can I employ to create a series of UI Elements from a collection of objects using WP

I'm new to WPF and before I dive in solving a problem in completely the wrong way I was wondering if WPF is clever enough to handle something for me. Imagine I have a collection containing objects. Each object is of the same known type and has two parameters. Name (a string) and Picked (a boolean). The collection will be populated at run time. I would like to build up a UI element at run time that will represent this collection as a series of checkboxes. I want the Picked parameter of any given object in the collection updated if the user changes the selected state of the checkbox. To me, the answer is simple. I iterate accross the collection and create a new checkbox for each object, dynamically wiring up a ValueChanged event to capture when Picked should be changed. It has occured to me, however, that I may be able to harness some unknown feature of WPF to do this better (or "properly"). For example, could data binding be employed here? I would be very interested in anyone's thoughts. Thanks, E FootNote: The structure of the collection can be changed completely to better fit any chosen solution but ultimately I will always start from, and end with, some list of string and boolean pairs.

Is it possible to dynamically change the style/template of a control?

- by elggarc

I am creating a UserControl in Silverlight 4 which has a watermarked background. The watermark should change depending on the underlying 'type' the UserControl is representing. The watermark is created using a Path and I have extracted all the properties into a style. I was wondering if it would be possible to change the style of the Path at runtime based on some known value. I am using MVVM and Unity. Perhaps I could bind the style somehow? Or could I inject the style when the view is created? I may have to do this with control templates, hence the reference in the title. Thanks...
