Hi,
We are using clientside databinding to populate our grids. To avoid "flickering" on load, the grid is bound to an empty datatable on serverside page load. However; when the grid gets databound&repainted on clientside, the rows don't get edit&delete buttons. There is just an empty whitespace where the buttons should be.

Hello Ronny,

RadGrid needs this empty rows that are created on server to populate them properly later when bound on client-side. There are certain columns that will be generated properly if there are no rows initially, but edit/delete will not. You can workaround this by handling client OnRowDataBound event and create the control manually for the cells.

However in order to avoid the flickering effect you can use another approach on ItemCreated server event if you hide all GridDataItems. For example:
protected void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)  
    {  
        if (e.Item is GridDataItem)  
        {  
            e.Item.Display = false;  
        }  
    }
