Hi,

I'm having an issue trying to form a complex layout scenario.
What I have is a master page with Top, Left and Center panels in a viewport

<ext:Viewport ID="Viewport1" runat="server" Layout="BorderLayout">
<Items>
<ext:Panel ID="pnlTop" runat="server" Region="North" Layout="HBoxLayout">
....
</ext:Panel>
<ext:Panel ID="pnlWest" runat="server" Width="161" Region="West" Layout="VBoxLayout" >
...
</ext:Panel>
<ext:Panel ID="pnlMain" runat="server" Region="Center" Padding="3">
<Content>
<asp:ContentPlaceHolder ID="ContentPlaceHolderMain" runat="server">
</asp:ContentPlaceHolder>
</Content>
</ext:Panel>

In My WebPage, using the MasterPage above I put inside the ContentPlaceHolderMain the items
<ext:Panel ID="dummy1" runat="server" Layout="FitLayout">
<Items>
<ext:Panel ID="dummy2" runat="server" Layout="BorderLayout">
<Items>
<ext:GridPanel ID="gridPanel1" runat="server" Title="Content Groups"
Region="West" Frame="true" Border="false" AutoExpandColumn="Name"
ForceFit="true" Width="500">
....
</ext:GridPanel>
<ext:Panel ID="ChannelsPnl" runat="server" Region="Center" Layout="FitLayout">
<Items>
<ext:GridPanel runat="server" Title="Channels" ID="gridPanel2" Region="Center"
Layout="FitLayout" SelectionMemory="Enabled" Frame="true" Border="false" AutoExpandColumn="Name"
ForceFit="true">
....

But it does not render correctly. Specifically the center panel of the master page show:
ctl00_pnlMain_Content - height is ~400px
And "dummy1" shows 4 px height with all is contents.

Why is that happening?

Thanks,
Dror
