Set binding value to page variable

BenRivet

Hi,<br />
<br />
I have a report that dynamically inserts report items that are fetch from a library.<br />
<br />
In the footer of the master page of the main report, I display the content of a page variable (called footnote).<br />
<br />
for each of my report items (they are all grids) that are in my library, inside the "onPageBreak" event, I have something like this :<br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>reportContext.setPageVariable( "footnote", "this is a footnote for item x" );</pre>
<br />
Up to now, everything I specified works.<br />
<br />
What I want to do is to assign my page variable to the result of a data binding column. (the binding is defined on the report item)<br />
<br />
I have tried assigning the page variable using the getRowData, but it doesn't seem to work.<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>reportContext.setPageVariable( "footnote", this.getRowData().getColumnValue( "indexName" ) );</pre>
<br />
I have attached a print screen to help visualize my description.<br />
<br />
<br />
How can I solve this ? Thank you !

Page variables are evaluated at render-time not at run-time. So getting the column indexName at render time in the code you posted will not work as you expect.<br />
<br />
You will need to either use a global variable and assign the indexName value to it. Then, you can use the global variable in the onPageBreak method.<br />
<br />
Or you can name a given element, and then reference its value in a page script from within the onPageBreak method.<br />
