David,

It works when I set hidden on the aspx. Doesn't otherwise, on any column, even a non template field.

head statement has runat server set appropriately.

<h

ead id="Head1" runat="server">
<title>WebCTS Client Summary</title>
<script type="text/javascript" src="includes\windows.js"></script>
</head>

            <ExpandButton AltText="Expand Row"></ExpandButton>
            <Behaviors>
                <ig:Sorting>
                    <ColumnSettings>
                        <ig:SortingColumnSetting ColumnKey="BoundColumn_4" />
                        <ig:SortingColumnSetting ColumnKey="BoundColumn_6" />
                        <ig:SortingColumnSetting ColumnKey="BoundColumn_7" />
                        <ig:SortingColumnSetting ColumnKey="BoundColumn_8" />
                    </ColumnSettings>
                </ig:Sorting>
            </Behaviors>
        </ig:WebHierarchicalDataGrid>

this worked for me;

WebHierarchicalDataGrid.GridView.Columns(0).Hidden = True

Hi,

I kind of forgot that this was the HierarchicalGrid.  If you set it on the WHDG itself, you are setting it on the band.  You would have to call WebHierarchicalDataGrid.RefreshBehaviors() to get it down.  Or you could set it yourself on WebHierarchicalDataGrid.GridView.Columns

NOPE! that didnt help. hiding column still not working.

heres my corrected script where the behaviors sections were combined

I just noticed that I have two behavior tags in the markup. Let me combine them. That surely cant be helping
