Unfortunately Hierarchical has not been supported in WebGrid Client Binding. Regarding the drag / drop, you could use the WebDragDropExtender control to use drag drop feature in WebGrid as demonstrated in the attached sample. The attached sample does not use client binding, however it should be similar iin client binding scenario.

We have an article in the WebGrid documentation titled "Client Binding Consideration and Best Practices" which you can read to have some insight about client binding approach.

Hi Glenn,

   Thanks again for your reply.

   - I tried the drag/drop client side binding and it didn't work for me.

   - Any future plans to support hierarchy tables on client side binding?

   - Is it possbile to use ISLINQDataSource with hierarchy tables?

Thanks,

Maged

I couldn't open the page containing this article: "Client Binding Consideration and Best Practices", it says it’s down due to maintenance; can’t you attach it on a word document pls?

Do you mind elaborating why the drag drop will not work on your project?

Currently, hierarchy table with client binding support is planned for the next major version of WebGrid. You could aslo bind hieararchical data using numerous data source, however in some data source you will need to define the object relation in outbound mode as discussed in this thread.

Our online documentation is currently offline, you need to open the provided WebGrid documentation with the WebUI Studio installation to lookup the article.

I am very sorry regarding the client binding and dragg drop misinformation. Based on the issue I handled on this thread, I have recieved a confirmation that in the latest version client binding WebGrid has not supported WebGragDropExtender yet. The support is planned in the next WebGrid major version.

IS the hierarchical client side binding is still not supported for WebGird version 10?

Sorry for the delay in sending this.

WebGrid is focused on complete support for client binding in flat Grid mode, to ensure high reliability with existing APIs and feature and best performance in various scenarios. The following features are not supported in version 7, although the architecture has been properly designed to support implementation for those features in the next version:

• Hierarchical Grid (Child Tables)
• Self Referencing

Hope this helps.
