Hello,
In my project when i dynamically create a DataGridView I am adding a Handler to the CellParsing event wit the following line:
My code in the Sub Routine Datgr_End_Update is an update command that updates my database when a value in the DataGridView is changed by the user.
However when I edit a value in my DataGridView the code runs, and the MsgBox pops up but the database doesn't get updated.
The strange thing is that when i put the code behind a button the code works perfectly and the database is updated :confused:
Am I creating the Handler correctly? I think that i am as when the cell value has changed the code in the Sub Routine runs, but why doesn't my database get updated?
Thank you for your time!!!
