And InitializeDataSource should load the root node data. And the columns are created in the code, not hardcoded in aspx page.</span></p> <p><span style="font-size: 13px">I think I have everything correct (too big to post here), but I just don't get the "plus" image to expand a node. How does WebGrid know if it needs to draw this plus image? What might be missing?</span></p> <p><span style="font-size: 13px">In any case such a sample would be great. I found the samples that use EnableLoadOnDemand (not supported in mentioned version) and the found samples mostly use data connectors in the aspx file, instead of creating the data in InitializeDataSource.</span></p> <p><span style="font-size: 13px">Thanks</span></p>
