Column width reinitialized on collapse/expand

[Damien]

Hello,

I use a TreeList with autogenerated columns. I allow the column resize.

<telerik:RadTreeList runat="server" ID="RadTreeList1"
                                                        Skin="Telerik"
                                                        AutoGenerateColumns="true"
                                                        DataKeyNames="DataKey" ParentDataKeyNames="ParentDataKey"
                                                        AllowSorting="true"
                                                        ItemStyle-CssClass="RowStyle"
                                                        AlternatingItemStyle-CssClass="AlternatingRowStyle"
                                                        HeaderStyle-CssClass="HeaderStyle"
                                                        SelectedItemStyle-CssClass="SelectedRowStyle"
                                                        OnAutoGeneratedColumnCreated="RadTreeList1_OnColumnCreated"
                                                        Visible="false"
                                                        >
                                        <ClientSettings>
                                           <Scrolling AllowScroll="true" UseStaticHeaders="true" />
                                           <Resizing AllowColumnResize="true" ResizeMode="NoScroll" />
                                        </ClientSettings>

                                   </telerik:RadTreeList>

So the final user can resize the columns, but, if he expands or collapses a node, the column widths are reinitialized.
How could I keep the width modifications.
Thanks by advance.

Damien

Hi Damien,

After a thorough investigation, our developers came to the conclusion that this behavior is a bug. You could track the process in our Ideas & Feedback portal. Note that this behavior is observed only when AutoGenerateColumns property is set to true. As a work around you could manually implement your columns and disable auto generated columns.
Additionally I updated your account with Telerik points.
