Hi All,
I have a data page which calls a webserver and fill this data page. Data page structure is like;

<pxResults REPEATINGTYPE="PageList">
	<rowdata REPEATINGINDEX="1">
		<TextEN>Text1</TextEN>
		<pxObjClass>"Class Path"</pxObjClass>
		<CategoryID>100</CategoryID>
		<Code>1</Code>
	</rowdata>
	<rowdata REPEATINGINDEX="2">
		<TextEN>Text2</TextEN>
		<pxObjClass>"Class Path"</pxObjClass>
		<CategoryID>100</CategoryID>
		<Code>2</Code>
	</rowdata>
	<rowdata REPEATINGINDEX="3">
		<TextEN>Text3</TextEN>
		<pxObjClass>"Class Path"</pxObjClass>
		<CategoryID>100</CategoryID>
		<Code>3</Code>
	</rowdata>
	<rowdata REPEATINGINDEX="4">
		<TextEN>Text4</TextEN>
		<pxObjClass>"Class Path"</pxObjClass>
		<CategoryID>101</CategoryID>
		<Code>4</Code>
	</rowdata>
	<rowdata REPEATINGINDEX="5">
		<TextEN>Text5</TextEN>
		<pxObjClass>"Class Path"</pxObjClass>
		<CategoryID>101</CategoryID>
		<Code>5</Code>
	</rowdata>
	<rowdata REPEATINGINDEX="6">
		<TextEN>Text6</TextEN>
		<pxObjClass>"Class Path"</pxObjClass>
		<CategoryID>101</CategoryID>
		<Code>6</Code>
	</rowdata>
</pxResults>

What I want is, pass to parameters in my dropdown which refers to CategoryID and filter this datapage for this categoryid.

Many Thanks,
Burak
