Hi Mike,
I have a performance problem when I add a Formula on 6 static columns and 10 dynamic columns. When I change a value in my grid it tooks 5 seconds to the grid to update the total of the actual column. So before I can change or enter a new value in another column I always have to wait 5 seconds which is to long. If a deactivate those Summary column then if a change a value in the grid it took less the 1 second. I send you my code that create the formula.I use a formula because in certain columns there are some value that I dont want to summarize. So in the formula I substract this value to obtain the result that i want. The total value per colum that I have to substract are in the DataTableTermePoGroupByYearAndMonth object which is a DataTable that I convert later on in a DataView to filter on a specific month
Is there something I do wrong that can explain why it is so long to update the value into the summary column?
Thanks in advance !

No I can not type a new value because I dont have the hand on the grid.
I am forced to wait 5 secondes
For exemple I type the value 10 in a column and I press the key Tab to pass to the next cells
Well it took 5 seconds before the cursor appears in the next cells . So until the cursor appears I can not type any new value in anay cells I have to wait. :)
If I deactivate the summary row then everything is normal and fast as it is suppose to when I change a value in a cells
Is there some Properties that I have to use with the CalcManager like Recalc()
When I change a value in the column A does all columns are recalculate or just the A column ?
Thanks in advance
yannh said:So before I can change or enter a new value in another column I always have to wait 5 seconds which is to long.
What exactly do you mean by this? Are you saying that the UI is unresponsive? The CalcManager works asynchronously by default. So unless you changed some properties on the CalcManager itself, it should not be locking up the UI.
Or do you just mean you don't want to type until you can see the calculated value?
