我相信我的所有代码都是正确的,但我无法让它工作。GridView 有 allowSorting = true。所以理论上,当我点击列标题时,gridview 中的 xml 应该按该列排序。XML 显示在 GridView 中,但根本不排序。我难住了。
DST_Test.Xml
<?xml version="1.0" encoding="utf-8" ?>
<root>
<data name="Test1.Text" xml:space="preserve">
<value>Please Pick Bare Pump</value>
<comment>Tab - Pump Configuration</comment>
</data>
<data name="Test2.Text" xml:space="preserve">
<value>Complete</value>
<comment>A07</comment>
</data>
<data name="Test3.Text" xml:space="preserve">
<value>Confirmed</value>
<comment>A01</comment>
</data>
</root>
DataSrcTransform.xslt
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

<xsl:output method="xml" indent="yes"/>
<!--<xsl:template match="@* | node()">

</xsl:copy>
</xsl:template>-->
<xsl:template match="root">
<root>
<xsl:apply-templates select="data">
<xsl:sort select="$sortby"/>
</xsl:apply-templates>
</root>
</xsl:template>
<xsl:template match="data">
<data>
<xsl:attribute name="ctrlname">
<xsl:value-of select="@name"/>
</xsl:attribute>
<xsl:attribute name="value">
<xsl:value-of select="value" />
</xsl:attribute>
<xsl:attribute name="comment">
<xsl:value-of select="comment" />
</xsl:attribute>
</data>
</xsl:template>
</xsl:stylesheet>
