Legend Checkboxes Not Clickable

tangone · Post by **tangone** » Mon Jan 21, 2008 7:14 am

Hi,

I have been struggling to get the Legend checkboxes to work. I am able to show the checkboxes by doing

webchart1.chart.legend.checkboxes = true

but after it showed up on the web page, I am not able to uncheck to hide the series.
What did I do wrong?
Are there other settings that need to be done in order to get it to work?
Is it related to the rendering method of the chart?

Appreciate your help.

Hi tangone,

You should do something as the example I posted here.

Hi Narcís,

After following the post, the checkboxes still appear as not "clickable", meaning they appeared as "image" (checkbox with tick).
Nothing happened when click (definitely because cannot click on an "image").
What might still go wrong?

Thanks.

Hi Narcís,

I managed to find out what's wrong with the ClickLegend event not firing, it needs to have AutoPostBack set to True. But after it was set to True, I need to double click the checkbox to check/uncheck it because the WebChart1_ClickLegend event will fire twice!

Besides, I need to disable the AutoPostBack because if it was enable, when I click on the series to "drill down" (this is another feature of my tool), it will "drill down" twice.

Is there a way to solve these issues?

Thanks a lot.

Hi tangone,

Yes, this seems to be a bug (TF02012763) which I've added to our defect list to be fixed for future releases.
