After upgrading to version 2012.3.1205.40, the following code:

<telerik:RadSplitter ID="trsCWCMPrimary" runat="server" BorderWidth="0" BorderSize="0" BorderStyle="None" Height="520px" LiveResize="true" Orientation="Vertical" ResizeMode="Proportional" Width="100%">

<telerik:RadPane ID="trpCWCMPrimaryTree" runat="server" Collapsed="false" Width="20%">

<telerik:RadTreeView ID="trtvCWCMPrimary" runat="server" CssClass="sfecua_chkrdo_dataLeftSmall" Height="99%" Width="100%" OnNodeClick="trtvCWCMPrimary_NodeClick" OnNodeCollapse="trtvCWCMPrimary_NodeCollapse" OnNodeExpand="trtvCWCMPrimary_NodeExpand" onclientnodeclicking="OnClientNodeClicking">

</telerik:RadTreeView>

</telerik:RadPane>

<telerik:RadSplitBar ID="trsbPrimarySecondary" runat="server" CollapseMode="Forward"></telerik:RadSplitBar>

<telerik:RadPane ID="trpCWCMSecondaryTableDetails" runat="server">

</div>

</div>

</div>

</telerik:RadPane>

</telerik:RadSplitter>

</td>

</tr>

No longer reacts as expected.

Previously, the RadTreeView in the left RadPane would be cut off (scroll bars appear) as the RadSplitBar was moved left. The rendered controls (IFrames, etc) in the right RadPane would shrink as the RadSplitBar was moved right. The behaviour I want.

NOW, the RadTreeView nodes, text bleeds over the RadSplitBar when initially rendered and when the RadSplitBar is moved left. It's as though the right RadPane is sliding under the left RadPane. The RadTreeView is visible superimposed over the contents of the right RadPane.

I have to revert to version 2012.3.1016.40.

Hi Carmen,

We are not aware of such behavior of RadSplitter. Unfortunately, the provided information is not enough to determine the exact cause of the issue. Could you please provide more detailed information on the specific scenario?

Could you prepare and send a simple fully runnable project reproducing the problem so we can investigate it further? For you convenience I am attaching my test page - as an alternative could you modify it to a point, where the problem occurs and send it back?

Hi Vesi,

We're experiencing this same issue. I am able to reproduce the behavior by changing your sample to include a string in the TreeView control that will bleed over to the over pane (e.g. change one of the "a" entries to something like "a really long string that will bleed over the splitter bar...").

I have noticed that this issue is isolated to IE and appears to be related to the document mode (it appears to work in Quirks mode). I was able to get the behavior to appear by using the developer tools and setting the document mode to IE 7 Standards. Unfortunately for me, we still have users using older browsers and are experiencing this with some clients.

HTH,
Tom

Hello,

Thank you for narrowing us on reproducing the issue. After a further investigation it turn out that this is a browser behavior caused by a broken box-model in IE7. In order to workaround it you have to set a "position: relative" style to the RadPAne, which is holding the TreeView:

<telerik:RadSplitter ID="RadSplitter1" runat="server" Height="520px" Orientation="Vertical"

Width="100%">

<telerik:RadPane ID="RadPane1" runat="server" Width="20%" CssClass="PanePosition"

Scrolling="Both">

<telerik:RadTreeView ID="RadTreeView1" runat="server" Height="100%" Width="100%">

</telerik:RadTreeView>

</telerik:RadPane>

<telerik:RadSplitBar ID="RadSplitbar1" runat="server">

</telerik:RadSplitBar>

<telerik:RadPane ID="RadPane2" runat="server">

</telerik:RadPane>

</telerik:RadSplitter>

<style type="text/css">

.PanePosition

{

position: relative;

}

</style>

Hello Vesi,

What i want is the same behaviour as RadGrid has. So a page with splitter on it and in it a full sized RadTreeList thats has it's own scrolling, showing paging on the bottom. Also columns are filled out and the scrollbar is not painted correctly (standard iso skin).

see the image attached for an example what i'm getting.

Hi Erik,

In order to make the TreeList reside according to its parent RadPane size, its ScrollHeight property should be also configured. The limitation here is that this property supports only values in pixels, so I would suggest you to use the following approach to make the calculations:

Assign handlers to the Splitter's OnClientLoad and OnClientResized events:

<telerik:RadSplitter ID="RadSplitter_Module" BorderSize="0" BorderStyle="None" PanesBorderSize="0" OnClientLoad="ResizeTreeList" OnClientResized="ResizeTreeList" ...>
Calculate the current height of the RadPane_Main, excluding the header's and footer's height of the TreeList and set it as a value to the TreeList data container:

function ResizeTreeList(splitter, args) {

    var pane = $find("RadPane_Main");

    var height = pane.get_height();

    var trlData = $get("RadTreeList1" + "_rtlData");

    var trlHeaderHeight = $get("RadTreeList1" + "_rtlHeader").scrollHeight;

    var trlFooterHeight = $get("RadTreeList1" + "_rtlFooter").scrollHeight;

    trlData.style.height = (height - trlHeaderHeight - trlFooterHeight) + "px";

}

For convenience I am attaching the modified project, so you could inspect it on your side.

Thank you Veselina,

It is a mistery to me why this is not working out-of-the-box, integration radSplitter with radTreeList/radTreeView?
