While defining width of the columns of the root band in %, I can not find property that define width of the column that carry expansion signs... After columns of the band got re sized, the first column with expansion signs get too wide, hoe to narrow it down.
Thanks
Hello mcseidel,
there is no such property but you apply css that set its width:
<style type="text/css"> .expandColumn { width: 25%; } </style>
<ig:WebHierarchicalDataGrid ID="WebHierarchicalDataGrid1" runat="server" Height="350px" ExpansionColumnCss="expandColumn" Width="400px" > </ig:WebHierarchicalDataGrid>
