    <p>sorry if this question is overly simple, but I'm having a hard time figuring out how to create backgrounds to controls - in the hopes that it will improve app performance.</p> <p>I have 9 different controls. All of them have a background. The backgrounds are made up of either images, other controls or both. All of those backgrounds have another background.</p> <p>Think of this like Power Point with slides, slide layouts and slide masters - inherited in that order. I have 9 slides / controls.</p> <ul> <li>The first 3 controls have the same "control layout" (let's call it <strong>ControlLayout1</strong>). <strong>ControlLayout1</strong> gets some of it's elements from <strong>ControlMaster1</strong>.</li> <li>The second 3 controls also have the same control layout, but it is different from the first. Let's call it <strong>ControlLayout2</strong>. It also inherits from <strong>ControlMaster1</strong>.</li> <li>The final set of 3 controls are different again. We can call them <strong>ControlLayout3</strong>. But this time, they inherit from a different master - <strong>ControlMaster2</strong>.</li> </ul> <p>Right now in each control I'm writing out all the XAML each time separately. I'm thinking there must be a way to not write these in each of these each item. Ideally, what I would like to create is one set of XAML that can be reused.</p> <p>Here's some pseudo-XAML:</p> <pre><code>&lt;UserControl x:Name="Control1"&gt; &lt;MyBackground (ControlLayout1)/&gt; &lt;/UserControl&gt; &lt;UserControl x:Name="Control2"&gt; &lt;MyBackground (ControlLayout2)/&gt; &lt;/UserControl&gt; &lt;UserControl x:Name="Control3"&gt; &lt;MyBackground (ControlLayout3)/&gt; &lt;/UserControl&gt; </code></pre> <p>And then somewhere for <strong>ControlLayouts</strong> (I don't know, like Application.Resources or elsewhere)</p> <pre><code>&lt;Canvas x:Name="ControlLayout1"&gt; &lt;MyMasterBackground (ControlMaster1)/&gt; &lt;/Canvas&gt; &lt;Canvas x:Name="ControlLayout2"&gt; &lt;MyMasterBackground (ControlMaster1)/&gt; &lt;TextBox Text="The Control 2"&gt; &lt;/Canvas&gt; &lt;Canvas x:Name="ControlLayout3"&gt; &lt;MyMasterBackground (ControlMaster2)/&gt; &lt;TextBox Text="The Control 3"&gt; &lt;/Canvas&gt; </code></pre> <p>And then for the <strong>ControlMasters</strong></p> <pre><code>&lt;Canvas x:Name="ControlMaster1"&gt; &lt;Canvas.Background&gt; &lt;ImageBrush ImageSource="/Images/image1.jpg" /&gt; &lt;/Canvas.Background&gt; &lt;/Canvas&gt; &lt;Canvas x:Name="ControlMaster2"&gt; &lt;Canvas.Background&gt; &lt;ImageBrush ImageSource="/Images/image2.jpg" /&gt; &lt;/Canvas.Background&gt; &lt;TextBox Text="Control Master 1"&gt; &lt;/Canvas&gt; </code></pre> <p>Once defined, the ControlLayouts and ControlMasters never need to change - they are static.</p> <p>Beyond just having a smaller XAP if I can put these all in one location and reuse the XAML, I'm hoping performance will be improved in my app as the ControlLayouts automatically get BitmapCached or something like that.</p> <p>So first, is there a good strategy to implement the above (the ControlLayouts and Masters do not have any code-behind)? Secondly will performance be improved in loading of Control1, Control2, etc.? Finally, if they were pure usercontrols (i.e. they had some code behind), would that be better for performance?</p> <p>Thanks in advance!</p>

    1. COIf you want static things to be BitmapCached, you should just set it manually. Certain things are [auto-cached](http://msdn.microsoft.com/en-us/library/ff602285(v=vs.95).aspx), but in my experience setting it manually can make a BIG difference, particularly when you are moving UI elements around a lot and seeing jerky performance.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
