Hi Ihab,

If you want to set the image urls for Expand mode and Collapse mode you can set the ButtonType property of the Column to ImageButton and also set the ExpandImageUrl and CollapseImageUrls respectively:
aspx:

    
            <telerik:GridExpandColumn ButtonType="ImageButton" ExpandImageUrl="../../Images/Image1.gif" 
        
             CollapseImageUrl="../../Images/Image2.gif"></telerik:GridExpandColumn>

If you want to set the grid rows expanded on page load then you can set the HierarchyDefaultExpanded property of the OwnerTableView object to true as shown below:

    
             <telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="Sqldatasource1">                
        
                            <MasterTableView HierarchyDefaultExpanded="true" DataSourceID="Sqldatasource1">

If this does not meet your requirement, feel free to get back with a bit more of explanation.
