Msdn datagridview cellvalidating invalidating postdata
Still, it doesn’t make much sense when we think about the way Check Box’s work, in that, they can only ever be On or Off, and that once you have made your selection, you’re probably pretty confident that you want to change the value.
Any solution is going to involve using an event that definitely will fire to stop the Data Grid View from thinking it’s in edit mode.
When this event is canceled in virtual mode, the Cell Value Pushed event will not be raised.
Handle the Cell Validated event to perform post-validation processing.
Data Grid View Cell Validating Event Handler Data Grid View Cell Validating Event Args Cell Validated Data Grid View Cell On Cell Validating Data Grid View Class System.
NET, but, not to fear, there are several easy work-arounds that will get the trick done.
When you click a Check Box in a Data Grid View Check Box Column, the check marker will update immediately, but Cell Value Changed event on the Data Grid View will not fire until the user happens to click elsewhere and the cell has lost focus. Well, the Data Grid View thinks it’s a little preemptive to go declaring that the cell value has changed while you are still selected on it.
The rest of the cell validations are perfectly working!
How am i supposed to edit the code so that it does not generate this error?
User select a row and edit the First Column, First Column Contains File Name. and Cell Parsing occures when you want Cell Parsing event is used to provide custom value conversion to the required type you have a button to update records in your form, if so you can write code on button click to update folder name by using directory class.
