DataTable.Clear() throws System.ArgumentOutOfRangeException

[Guest]

Clearing a datatable of all data, I would think be a simple task. Does anyone have an idea why the DataTable.Clear() method could throw a System.ArgumentOutOfRangeException. Also, this problem doesn't seem to be consistent or 100% reproducable. Perhaps it depends on the data in the table. Any suggestions? Sorry the description is so vague, but there really is anymore info I can think to add.

Huh,

Is your datatable binded, are you implementing its events, calculated
columns, anything?

Yes, the table is bound to a grid. There is a calculation column but it
was added through the grid, not through the datatable. Example:

grid1.Band[0].Columns.Add("CalculatedColumn",typeof(decimal));

Hi David,

a) Try detaching datatable from grid before calling clear
b) try removing calculated column before clear
