<p>Contains a trigger formula generated by Microsoft Office Visio that determines whether to move the begin point of a 1-D shape to maintain its connection to another shape.</p>
</p><h2>Syntax</h2><pre><code>
<BegTrigger>
[Unit]
[F]
[Err]>
</BegTrigger>
</code></pre><h2>Attributes</h2><p>
<b class="bterm">Unit</b>
</p><p>Optional string. Represents a unit of measure. The default is NUM. For details about NUM, see <a href="vixmlconUnitsOfMeasure.htm" id="HV83150825" lcid=" ">Units of measure</a>.</p><p>
<b class="bterm">F</b>
</p><p>Optional string. Represents the element's formula. This attribute can contain the string "<b class="bterm">someFormula</b>" if the formula exists locally, "No Formula" if the formula is locally deleted or blocked, or "Inh" if the formula is inherited.</p><p>If the attribute is not present, the element's formula is a simple constant, for example, <<b class="bterm">element</b>>5</<b class="bterm">element</b>>.
</p><p>
<b class="bterm">Err</b>
</p><p>Optional string. Indicates that the formula evaluates to an error. The value of <b class="bterm">Err</b> is the current value (an error message string); the value of the element is the last valid value.</p><h2>Element properties</h2><table><tr><th>Property</th><th>Value</th></tr>

</table><h2>Element information</h2><p><b class="bterm">Parent elements</b></p><p><a href="vixmlelemMisc.htm" id="HV01085541" lcid=""><b class="bterm">Misc</b></a></p><p><b class="bterm">Child elements</b></p><p>None</p><h2>Remarks</h2><p><p>When you glue a 1-D shape to another shape using dynamic glue, Visio generates a formula that refers to the <a href="vixmlelemEventXFMod.htm" id="HV01085417" lcid=" "><b class="bterm">EventXFMod</b></a> element of the other shape. When that shape is changed, Visio recalculates any formula that refers to its <b class="bterm">EventXFMod</b> element, including the formula in the <b class="bterm">BegTrigger</b> element. Other formulas for the 1-D shape refer to the <b class="bterm">BegTrigger</b> element and move the begin point of the 1-D shape or alter the shape as needed.</p>
<p>The <b class="bterm">BegTrigger</b> element is relevant only when contained in a <a href="vixmlelemShape.htm" id="HV01085631" lcid=" "><b class="bterm">Shape</b></a> or <a href="vixmlelemStyleSheet.htm" id="HV01085684" lcid=" "><b class="bterm">StyleSheet</b></a> element. It is ignored when contained in a <a href="vixmlelemDocumentSheet.htm" id="HV01085388" lcid=" "><b class="bterm">DocumentSheet</b></a> or <a href="vixmlelemPageSheet.htm" id="HV01085573" lcid=" "><b class="bterm">PageSheet</b></a> element.</p></p><h2>See also</h2><p><a target="_blank" href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vissdk11/html/DSS_Cells_A-C_1330.asp" id="HV82251330" lcid=" ">BegTrigger</a> cell (Glue Info section)</p><center><a href="XMLSchemaCopyright_HV01147162.htm">©2003-2004 Microsoft Corporation.
