public class RepeaterHeader
extends RepeaterComponent

This tag is used to render the header of a Repeater. This header may contain any markup or tags that can be rendered to a page. In the case of starting a table, ordered list, or unordered list, the HTML elements <table>, <ol>, and <ul> could respectively be rendered inside the body of this tag. There is no data item present at the time that the RepeaterHeader renders, so tags in the body can not reference the container databinding context to access a current item or index, though other databinding contexts are available.

The RepeaterHeader renders exactly once in a table during the Repeater tag's Repeater.HEADER rendering state.

Repeater, RepeaterItem, RepeaterFooter, Serialized Form

Example:

The following sample renders the data set as an HTML table. The table has two columns, "index" and "name", and each iteration over the data set is rendered a row of the table. The <netui-data:repeaterHeader> tag renders once, before the iteration has begun. It renders an opening HTML table tag and two header rows for the table.

    <netui-data:repeater dataSource="{pageFlow.myDataSet}">
        <netui-data:repeaterHeader>
            <table border="1">
                <tr>
                    <td><b>index</b></td>
                    <td><b>name</b></td>    
                </tr>
        </netui-data:repeaterHeader>
        <netui-data:repeaterItem>
            <tr>
                <td>
                    <netui:label value="{container.index}" />
                </td>
                <td>
                    <netui:label value="{container.item}" />
                </td>
            </tr>
        </netui-data:repeaterItem>
        <netui-data:repeaterFooter>
            </table>
        </netui-data:repeaterFooter>    
    </netui-data:repeater>

Beadoc.tagdescription:

This tag is used to render the header of a Repeater tag. This header may contain any any HTML markup that can be rendered to a page. In the case of starting a table, ordered list, or unordered list, the HTML elements <table>, <ol>, and <ul> could respectively be rendered inside the body of this tag.

There is no data item present at the time that the <netui-data:repeaterHeader> renders (because the iteration of the <netui-data:repeater> tag has not yet begun), so tags in the body can not reference the {container...} data binding context to access the current item in the data set, though other databinding contexts are available.
