title: What impact does the Z Index number have in an RDLC file?
body: <p>I have been creating rdlc reports from scratch using C# to write xml files.  To make sure I do this properly I look at the XML behind other reports I created using the VS 2008 report designer feature.  When I look at the XML for the reports created using VS, I see the field called ZIndex which as a integer value associated with it.  What is the importance of this field?  Below you will see that the ZIndex value is 238.</p>
  
  <p>Example:</p>
  
  <pre><code>                   &lt;Textbox Name="FULL_NAME"&gt;
                        &lt;rd:DefaultName&gt;FULL_NAME&lt;/rd:DefaultName&gt;
                        &lt;Style&gt;
                          &lt;FontSize&gt;8pt&lt;/FontSize&gt;
                          &lt;PaddingLeft&gt;2pt&lt;/PaddingLeft&gt;
                          &lt;PaddingRight&gt;2pt&lt;/PaddingRight&gt;
                          &lt;PaddingTop&gt;2pt&lt;/PaddingTop&gt;
                          &lt;PaddingBottom&gt;2pt&lt;/PaddingBottom&gt;
                        &lt;/Style&gt;
                        &lt;ZIndex&gt;238&lt;/ZIndex&gt;
                        &lt;CanGrow&gt;true&lt;/CanGrow&gt;
                        &lt;Value&gt;=Fields!FULL_NAME.Value&lt;/Value&gt;
                      &lt;/Textbox&gt;
  </code></pre>
