Hi Paurnima,
Thank you for your interest in Syncfusion products.
We analyzed your reported scenario at our end. The exception(Specified argument was out of range of the
valid values) may be occurred if RowIndex or column index does not
correctly checked for your scenario. So that we need some more details
regarding your customization in TableControlCellDoubleClick
event(in which case, another form should open). Please provide us your code
snippet(customization) in TableControlCellDoubleClick.
It would be more helpful us to provide better solution as soon as possible.
Please let me know if you have any concerns.
