Dynamic Watermark based on row data
cambrown28
<p>Hi</p><p> </p><p>Is it possible to add a watermark to a BIRT report if the value of the row "status" is "CAN" but not display the watermark if the value of "status" is anything else.</p><p> </p><p>I have tried this with Master Pages and background images but I cannot work out how to make this dynamic based on data from the report.</p><p> </p><p>I can create a dynamic image (which works) but the problem is where to put it.</p>

<p>What version of BIRT are you using?</p>

<p>Hi</p><p> </p><p>Sorry, should have mentioned that. It is BIRT 3.7.1</p><p> </p><p>I don't mind how this is done (if it can be), any possible solutions are greatly appreciated.</p><p> </p><p>Cam</p>

<p>I am sorry, I thought I could change the image using an expression. That does not seem to be the case. The only workaround that I can think of is to use a background image in the layout itself. If this is a fixed page number report one can put a grid around the content and add the background image to the cell of the grid.</p>

<p>Thanks for the reply. I am still not sure how to make this dynamic based on row data.</p><p> </p><p>I can put a grid around the content and add the background image to the cell of the grid (if I am assuming correctly, this is done via the Advanced properties of the cell) but how do I change that image based on row data?</p><p> </p><p>Cam

</p></div></blockquote><p>You add code to the onRender something like this:</p><div><pre class="_prettyXprint">if (this.getRowData().getColumnValue("STATUS") == "CAN") {this.getStyle().backgroundImage = "myimage.png";}else {this.getStyle().backgroundImage = "";}</pre><p>If you do not have access to the row data in the grid use a page or report variable. See attached example using Classic Models.</p></div><p> </p>
