Thanks for the help! I ended up doing a test yesterday to see if maybe it was a problem with my cms, or some javascript on the page.  It wasn't any of those, but placing a new datagrid on the page and changing the datasource type seemed to fix it.  I'm not sure if that was what caused the issue.  The last version I used is almost the exact same as the one posted above.

 
     <ig:WebDataGrid ID="SoftwareGrid" runat="server" Width="440" DataKeyFields="ID"
                                                AutoGenerateColumns="false" ShowHeader="false" ShowFooter="false" OnRowSelectionChanged="SoftwareGrid_RowSelectionChanged">
                                                <Columns>
                                                    <ig:TemplateDataField Key="ID">
                                                        <ItemTemplate>
                                                            <table>
                                                                <tr>
                                                                    <td>
                                                                        <%# Eval("Product_Image")%>
                                                                    </td>
                                                                    <td>
                                                                        <%# Eval("Product_Name")%>
                                                                    </td>
                                                                </tr>
                                                            </table>
                                                        </ItemTemplate>
                                                    </ig:TemplateDataField>
                                                </Columns>
                                                <Behaviors>
                                                    <ig:Activation Enabled="true" />
                                                    <ig:Selection Enabled="true" RowSelectType="Single" CellClickAction="Row">
                                                        <AutoPostBackFlags RowSelectionChanged="true" />
                                                    </ig:Selection>
                                                    <ig:RowSelectors RowNumbering="false" Enabled="true">
                                                    </ig:RowSelectors>
                                                </Behaviors>
                                            </ig:WebDataGrid>

Hello mario101,

Here I have created a sample with this theme and I am attaching it here. You can download and review it. In my case it worked fine with normal behavior. Please review it and note if  I missed something.

Looking forward to hear from you.

Wow, embaressing for me.  Totally missed that part about selection in your code.  My apologies.  But the fact that you have Claymation could help.  It looks like a regular row selector have the correct class.  Now you'll need to click on a cell so that it is selected/active.  Then you'll need to examine the live html of the row selector.  Like with IE Dev toolbar of Firebug in Firefox.  It should have the classes I mentioned, just with ClayMation after the '_'.  But it may be that the look of this style does not have the arrows you're expecting.  If this is the case, you'll need to style it yourself.

How do I enable selection then? Isn't that what this line is for?

I'll check to see if I'm missing the css classes.

<

ig:Selection RowSelectType="Single" Enabled="true" CellClickAction="Row" />
<ig:RowSelectors RowNumbering="true" Enabled="true" ></ig:RowSelectors>

The resulting table seems to have an rowselect class attached to it:

<table cellspacing="0" cellpadding="0" border="0" style="table-layout: fixed; width: 100%;
                                        visibility: hidden" id="x:431846697.4:mkr:dataTbl.hdn">
                                        <tbody id="x:431846697.8:mkr:rows:nw:1" class="ig_ClaymationItem igg_ClaymationItem">
                                            <tr id="x:431846697.9:adr:0:tag:">
                                                <th class="ig_ClaymationHeader igg_ClaymationRowSelector ">
                                                    1
                                                </th>
                                                <td>
                                                    <img src="~/media/Waspbarcode/ProductImages/LargeImages/wasp_wasplabeler_lg.ashx?h=25"
                                                        alt="" width="25" height="25" />
                                                    Wasp Labeler
                                                </td>
                                            </tr>
