This method returns the Boolean value and checks whether the selected record contains children or not. Based on that indent column, the child level is calculated.
NET forums is how to deal with exceptions like The Grid View 'Grid View1' fired event Row Editing which wasn't handled.
We can implement it in this way without a performance impact because the data is not actually retrieved from the database until required, so we can build up a chain of queries up to that point and only the end result will be pulled from the database. When manually databinding the Grid View, this will always show ascending, so we need to handle this manually with the following logic: After that we save the new Sort Expression.
We’re sorting on the appropriate field based on the Sort Expression, and setting the direction based on Sort Direction by calling either the Order By or Order By Descending methods. As with paging, we also reset the Edit Index and Selected Index when sorting.
This method returns the Boolean value and checks whether the row is expanded or not when you click the Tree Grid Template Control.

Sql Data Source, Object Data Source, Linq Data Source, etc) specified in a Data Source ID, the Grid View can automate many functions because, through the data source control, the Grid View on its own can perform the following operations: When you manually bind data to a Grid View, the Grid View itself cannot perform these operations, so they must be implemented in your code.The Grid View does know the events that should be used to implement them, so the exceptions shown above are thrown when you try to perform one of these operations, but you have implemented the appropriate event handler.
