aal rows in edit mode en grouping

[glenn]

hi,
When i put all rows in edit mode and i group on a column, the collpase button does'n work anymore.

I put all rows in edit mode as described in the manual:

protected void PreRenderEventHandler(object sender, EventArgs e)
        {
            foreach (GridItem item in MasterTableView.Items)
            {
                if (item is GridEditableItem)
                {
                    GridEditableItem editableItem = item as GridDataItem;
                    editableItem.Edit = true;
                }
            }
            Rebind();
         }
}

The collapse button works if i put the for loop and the rebind call in !IsPostback. But then if a postback happens, all my rows are not in edit mode anymore
Can someone help me?
Thx in advance

I solved this by grouping client side
