Hi @tobros,

The problem is the Columns' IDs.

ID="Day"

ID="VouchNo"

etc.

The columns of each inner grid renders with those IDs, but they must be unique. If you don't use those IDs, it might be best just to remove them.

I understand ! But I need those IDs. I want to dynamic display hidden columns using a script . please ask me how to do ???

Please use a Column's ItemID.

For example:

<ext:Column ItemID="Column1" runat="server" Text="Test 1" DataIndex="test1" />

var column = App.GridPanel1.getView().getHeaderCt().items.get("Column1");
