lastValue (Combo Box Last Saved Value) |
Specifies the value associated with the current display text for the combo box structured document tag. If this structured document tag is not mapped to XML using the dataBinding element (§17.5.2.6), then this attribute shall be ignored. If this structured document tag is mapped to XML, it shall be used to determine whether the current display text in the combo box structured document tag shall be retained when the document is opened, as follows:
[Example: Consider a combo box structured document tag defined as follows: <w:sdt> <w:sdtPr> <w:dataBinding … /> <w:comboBox w:lastValue="2"/> </w:sdtPr> <w:sdtContent> <w:r> <w:t>Hello world</w:t> </w:r> </w:sdtContent> </w:sdt> The current run content of the structured document tag reads Hello world. When this document is opened, if the current value of the associated custom XML data is 2, the matching lastValue attribute specifies that the contents of the combo box must continue to be the current display text of the combo boxeven though there is no listItem whose value is 2 (and normally, the content of the structured document tag would be set to 2. Essentially, this attribute specifies a listItem whose value is 2 and whose displayText is Hello world (the current structured document tag contents). end example] The possible values for this attribute are defined by the ST_String simple type (§22.9.2.13). |
