Radgrid not updating after rebind
Rad Grid provides an API for inserting new data, updating existing data and deleting data from the specified data source.
That is why,if you have template columns for example, and you have to search for a control that is in the edit template, you should search the Edit Form Item instead of the edited item. Rad Gridsupports hierarchical database structure or building hierarchy through self-referencing source table (having ID-Parent ID relations in the same Data Table).
It alters the "traditional"editing style by displaying an edit form item (row), below the item currently being edited, instead displaying the in-place editors. Additional details can be found in these help resources: In Place editing Edit Forms editing Custom edit forms To better understand how Rad Grid deals with hierarchy, refer to the article: Understanding hierarchical grid structure.
Unlike the Data Grid/Grid Viewcontrol, Rad Grid supports the Edit Forms feature that is set by default.

When deleting an item, Rad Grid extracts the values from the cells of the Grid Item that is to be deleted.
