Specifying a json or xml field as part of the table indeed triggers an error, but it's a backend 42804 error because npgsql sends values as text. However, it doesn't look like what you got, and moreover I can see no issue when inserting timestamps (with timezone or otherwise). Sorry that it took some time to write back - my internet connection was (is) down - I've got to work via mobile... Please look at my testcase and try to see if there's any real difference with your code. So - for the exception call stack - it only has external code - maybe I need to include the npgsql source for more information on this. Updating Row Status Errors(Row Updating Event Args row Updated Event, Data Row data Row) at System. But - when I have a row with some higher type, for e.g. I'm using Npgsql (188.8.131.52) via Nu Get with Target Framework 4.5 But I also tried the Npgsql download version for and with 2.0 - same issue. Update From Data Table(Data Table data Table, Data Table Mapping table Mapping) at System.
To cancel the update operation, set the collections, if necessary, before the values are passed to the data source.A common way to use these collections is to HTML-encode the values supplied by the user before they are stored in the data source. Exception: Thrown: "Die angegebene Umwandlung ist ungültig." (System. Invalid Cast Exception was thrown: "Die angegebene Umwandlung ist ungültig." Time: Thread: In the exception itself: When I use your example an exception on Date Time is thrown: An unhandled exception of type 'System. Additional information: Type of value has a mismatch with column type Couldn't store @digital-void, I'm using 2.2.0, which is the latest. Just to be absolutely sure, I created this failed repro commit on top of 2.2.0, with the timestamp_with_timezone column. Can you please try to run this specific unit test (not within your program) and confirm that on your setup produces an exception? If you need help compiling/running with NUnit let me know. "time with time zone" or xml either a Missing Operator- (xml = text) or an Invalid Cast-Exception occurs. Here the example code, To reproduce the issue - just setup a database with a table - first add only primitive data-type rows (int , uid, string, text ect.) test it - and you'll see - update just works fine.
Then add any extended data-type, like a time value, xml etc - and the update throws the exceptions @digital-void, please check the minimal testcase in my commit above. Update(Data Row data Rows, Data Table Mapping table Mapping) at System.
This enables you to provide an event-handling method that performs a custom routine, such as canceling the update operation, whenever this event occurs.
A Grid View Update Event Args object is passed to the event-handling method, which enables you to determine the index of the current row and to indicate that the update operation should be canceled.
event is raised when a row's Edit button is clicked, but before the Grid View control enters edit mode.
This enables you to provide an event-handling method that performs a custom routine, such as canceling the edit operation, whenever this event occurs.
