I imagine that I will either have to post my entie code or open an incident for this but I will try this first. I have a grid that mimics the server-side select example found here:

http://www.telerik.com/DEMOS/ASPNET/Prometheus/Grid/Examples/Programming/SelectRowWithCheckBox/DefaultCS.aspx

However, I have some slight difference:

1. I have a needdatasource event to populate the grid from Oracle
2. I have an ItemDataBound event to change the background color of certain cells.
3. I have a DetailTable for a grid within the grid heirarchy. (the detailtable does not allow selection)

I am encountering an issue where the selection is hit-or-miss. Most of the time, I can select two items but, upon selecting the third, the first two become unselected. Also, If I select a row then expand it, the selection is removed.

Does this sound like I am missing something obvious? I am putting together a sample project just in case.

Thanks in advance.

I came across this same issue with me hiding a portion of the grid to use scrolling.

    
            <ClientSettings> 
        
             <Scrolling AllowScroll="true" UseStaticHeaders="true" ScrollHeight="88px" /> 
        
            </ClientSettings>

I used the GridTemplateColumn to do the serveer side selecting like in your online demo example.

When scrolling down and selecting more items the above rows are deselected, but the checkbox's are still checked atleast.

I did the following in the example to reselect the rows that were not visible from the scroll.

    
                protected void ToggleRowSelection(object sender, EventArgs e) 
        
                { 
        
                    ((sender as CheckBox).Parent.Parent as GridItem).Selected = (sender as CheckBox).Checked; 
        
                    //ReSelect rows that are checked. 
        
                    foreach (Telerik.Web.UI.GridDataItem dataItem in RadGrid1.MasterTableView.Items) 
        
                    { 
        
                        if ((dataItem.FindControl("CheckBox1") as CheckBox).Checked) 
        
                            dataItem.Selected = true; 
        
                    } 
        
                }
