Hi Yeroon,
This is not a problem with our control, but expected behavior. When the DockZone is empty and the user is about to place a dock inside the zone is "highlighted" instead of showing the dock's placeholder. The placeholder is shown when there is more than one dock in the zone.
If you want to show the placeholder in the case when the zone is empty use the following workaround:
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
<head id="Head1" runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<script type="text/javascript">
///Show the placeholder even if the DockZone is empty
Telerik.Web.UI.RadDockZone.prototype._showPlaceholder = function(dock, location)
{
this._repositionPlaceholder(dock.get_element(), location);
var dockBounds = dock._getBounds();
var placeholderMargin = dock._getMarginBox(this._placeholder);
var placeholderBorder = dock._getBorderBox(this._placeholder);
var horizontal = this.get_isHorizontal();
var placeholderStyle = this._placeholder.style;
placeholderStyle.height = dockBounds.height - (placeholderMargin.vertical + placeholderBorder.vertical) + "px";
placeholderStyle.width = this.get_fitDocks() && !horizontal ? "100%" : dockBounds.width - (placeholderMargin.horizontal + placeholderBorder.horizontal) + "px";
placeholderStyle.display = "block";
return;
}
</script>
