Hi there --

I've built a little Javascript function to properly set the height of my Splitters when they're loaded on a TabPanel that keeps them hidden at the completion of the page's load event.  However, there's trouble in paradise: When I try to grab the new height variable with a call to pane.getContentElement().scrollHeight... I get zero as a result!

This definitely isn't right; there's a 600-pixel tall image in the pane.  What's going on?

Thanks,

Jesse

function ResetRadPaneHeight(splitterID, paneID) {
    var splitter = $find(splitterID);
    if (splitter) {
        splitter.repaint();
        var pane = splitter.getPaneById(paneID);
        var height = pane.getContentElement().scrollHeight;
        if (height != 0) { // if height is 0, something is amiss...
            splitter.set_height(height);
            pane.set_height(height);
        }
        else
        {
            alert('For some reason ' + paneID + '.getContentElement().scrollHeight = 0');
        }
    } else {
        // recursively try this function again in 1 second
        setTimeout('ResetRadPaneHeight(\'' + splitterID + '\', \'' + paneID + '\');', 1000);
    }
}

Hi Jesse,

I tried to reproduce the problem with the provided JavaScript function but to no avail. Could you please provide more detailed information regarding the specific scenario?
  • Which version of RadControls and .NET Framework are used in the application?
  • Under which browser and its version the problem occurs?
  • Could you please provide sample runnable project that reproduces the problem so we can investigate it further?

For your convenience I have attached my test project. Please modify it to a point where the problem occurs, open a support ticket and send it back - we will check it right away.

All the best,
