I use the UltraWebGrid control, which is bound to two tables. When deleting the main table, there is no problem, and even the child table will be deleted. However, when deleting the rows of the child table, an error is reported, saying "the index exceeds the array limit" And the tracking program can't follow anything, what is the reason, or what may be the reason?

That is, there is no such index value in the current array. Single-step debugging to see if an index that does not exist in the current array is called.

Catch the exception or make a simple range judgment

There was a mistake when taking the primary key value.It may be that the primary key was not put in the value when binding.
