Question

I am an old time user of the Array of controls in VB back in the days. It is gone now, so I am looking for a replacement.

I have created an User Control in C# for Silverlight. This control exposes a bool property IsChecked.

<ImageButton Name"imgbutton1" IsChecked="True"/>
<ImageButton Name"imgbutton2" IsChecked="False"/>
<ImageButton Name"imgbutton3" IsChecked="False"/>

In a Child Window, I populate a series of these controls and use them as an equivalent of RadioButtons, i.e., when I click one, any other that has an IsChecked = true will be set to false, for which I thought of doing something like:

List<ImageButton> imgButtons= new List<ImageButton>();
imgButtons.Add(imgbutton1);
imgButtons.Add(imgbutton2);
imgButtons.Add(imgbutton3);

Then, to clear all of their IsChecked but the one I need (pointed by some ‘index’ variable), I would do something like:

foreach (ImageButton imgbutton in imgButtons) imgbutton.IsChecked = false;
imgbuttons[index].IsChecked = true;

The problem I have is that List<ImageButton> is not compiling. I am very flaky at collections and can’t figure out what I am missing. I can do for standard controls but doesn’t allow me to get a user control in there.

Thanks!

PS: I have thought of just customizing a RadioButton control but don’t have Blend and I am using this image control for other types of controls. However, if you think there is a better way to implement this, please let me know.

EDIT: Compiler says “The type or namespace name ‘ImageButton’ could not be found (are you missing a using directive or an assembly reference?)’

Answer 1

Ensure that you have a reference to your “ImageButton” control in your code (in the “using” part).

To do that automatically you can just rightclick on your “ImageButton” in your code and click “Resolve”, it will automatically add the Reference
