How to know when the report preview is rendered completely?

Post by titanotam » Tue Oct 03, 2017 10:38 am

Hi,

I'm working on the report preview panel, my report has a lot of charts and data.
When I click the Preview button, it take too long for the report to render completely.
And when it rendered, I will capture the report image for making its thumbnail.
But I could not find any method that fires after the report is render completely.

Someone please help me.
Thanks :)

Hello,

You can check the StiEndRenderEvent event.

Thank you.

In this event, I use the html2canvas library to capture the image of report and save it as report thumbnail. So I need to make sure that the report is rendered completely
Thanks

Hello.

But the report is stored not in HTML format.
It's better to use an event of the Viewer.
Please, look at this sample.

Thank you.

The html2canvas library can take the html DOM by jquery, then capture the image, in my case this is:

Code: Select all

html2canvas($('div.stiJsViewerPageShadow'), { <--- This is the DIV that hold the rendered report
  onrendered: function(canvas) {
    //convert canvas to image then save as report thumbnail
  }
});

Hello.

Did you solve your issue?
Can you create a thumbnail?

Thank you.

Still not yet :(
I only create a full thumbnail after setting timeout for about 5000 ms. It’s not a good idea. :)

Can you please show me how to use the StiEndRenderEvent event?

Hello.

Unfortunately, there is no such event and the StiEndRenderEvent will not help you.
Maybe it will be better to export the report to HTML and then you can do with this HTML all that you need.

Thank you.
