Hi,
Please help answer my question if Batch Updating and Manual CRUD works for WHDG?
If it works, can you explain how does the various Postback events run? (Eg. From Pageload to RowAdding..etc for every rows updated?)
Take Adding a new row for example; And on every RowAdding event, are we able to databind only at the end of the LAST raised RowAdding event? Or must we databind on EVERY RowAdding event?
Please help me urgently!
Thank you,
Chinho

Hello Chinho,
Please do not hesitate to contact me if you have any further questions regarding this scenario.
Thank you for your questions !
WebHierarchicalDatagrid does support Manual CRUD with batch updating. The manual CRUD events (adding/deleting/updating) are fired sequentially at the control event handling stage, i.e after Page_Load. For instance, if there are multiple new row additions, the RowAdding event would be fired once for each one, starting with the row that was added first on the client. Rebinding the grid on each row addition therefore should not be necessary, as what is really being edited is the datasource itself. The grid may therefore be bound on the last row to be added, but for convenience it may be more approapriate to call DataBind at the PreRender stage when all CRUD operations are already done.
I am attaching a small sample illustrating this in a DataSet. Hope this helps. Please do not hesitate to contact me with any questions.
