Hi,

I have a very simpler splitter with a left and right pane.
The left pane is a navigator (treeview) and is intended to be a fixed width, unless the user specifically resizes it.
If the user changes the width of their browser window in Windows (IE, Firefox or Chrome), the left pane remains a fixed size (as desired) and the right pane has its width pro grammatically changed (see Javascript below).
If the user does the same thing on a browser on the MAC (have tried Firefox, Chrome and Safari), the left pane will grow in width as the user drags the browser window to enlarge it.

Note: Ignore th

e name MiddlePane - it's really the right pane (there used to be three).

Also, dv is a DiagramView (from MindFusion).



Nowhere in my code do I explicitly set the width of the left pane - only the right (middle) one.



Any ideas on what might be causing this?



Thanks in advance.



Jim

var splitter = $find("<%=RadSplitter1.ClientID %>");

if (splitter != null)

{

var leftpane = splitter.getPaneById('<%= LeftPane.ClientID %>');

var midpane = splitter.getPaneById('<%= MiddlePane.ClientID %>');

var leftWidth = leftpane.get_width();

}

var dv = document.getElementById("<%= DiagramView1.ClientID %>");

var marginsPlusSpltibar = 35;

if (leftpane != null)

{

//alert("In Resize Main");

// The more standards compliant browsers (mozilla/netscape/opera/chrome/IE7) use window.innerWidth and window.innerHeight

if (typeof window.innerWidth != 'undefined')

{

//alert("One");

alert("leftWidth = " + leftWidth);

var txtBannerHeight = document.getElementById('<%=txtBannerHeight.ClientID%>');

var bannerHeight = 0;

if (txtBannerHeight != null)

bannerHeight = parseInt(txtBannerHeight.value);

var newHeight = window.innerHeight - 270 + bannerHeight;

midpane.set_height(newHeight);

leftpane.set_height(newHeight);

var newWidth = (window.innerWidth - leftWidth - marginsPlusSpltibar);

midpane.set_width(newWidth);

splitter.set_height(newHeight);

splitter.set_width(window.innerWidth);

if (dv != null)

{

dv.style.height = (newHeight - 24) + "px";

dv.style.width = (newWidth - 5) + "px";

}

Me again,

Another bit of information I omitted.
The Javascipt code I provided earlier (which is part of a function called Resize) is called under the following circumstances:

Sys.WebForms.PageRequestManager.getInstance().add_endRequest(Resize);
window.onresize = onload = Resize;
for the following events:
function splitterLoaded(sender, eventArgs)
            {
                Resize();
            }

            function leftPaneCollapsed(pane)
            {
                Resize();
            }

            function leftPaneExpanded(pane)
            {
                Resize();
            }

Hi Jim,

I tried to reproduce the descibed behavior but to no avail. If I understand the scenario correctly, you want to have a Two RadPanes Splitter - the left one to be fixed in size and the right one to take all the remaining width of the window. If this is the case, I will suggest you to use the approach from this help article in order to make the Splitter occupy the whole wanted space, leaving the control to calculate its sizes by its own.

Additionally, if you describe in more details what is the exact scenario and layout you want to achieve, we could suggest you what would be the best approach and to narrow you how to implement it. A sample fully runnable project demonstrating it would be also of a great help for providing you with most to the point answer.

All the best,
