Written by Charnjit Singh Dharival

The following error generates when scrolling to the right, within task planner, to see more detail. This error will not disappear when clicking OK and have to crash out of system:
​
​The following exception occurred in the DataGridView:
​
System.ArgumentException: DataGridViewComboBoxCell value is not valid.
​
To replace this default dialog please handle the DataError event.


The functionality has been enhanced in Orchestrate version 7.62. Please upgrade to this version or above. If you cannot upgrade yet, implement the following workaround on your current plan:

  1. Log into Orchestrate and open the plan

  2. Select tools

  3. then custom Lists

  4. then supply status (last saved)

  5. click edit and then click new row

  6. Enter 0 in sequence and NA in value and select a green colour in field for Fill Colour column

  7. Enter 1 in sequence and OK in value and select a green colour in field for Fill Colour column

  8. Enter 2 in sequence and problem in value and select a red colour in field for Fill Colour column

  9. Click Apply and then OK

  10. You will then be able to scroll horizontally right to the end of the task planner with no error generating.
