Csharp datagridview cellvalidating

posted by | Leave a comment

I found a suitable code for it from the msdn library.Unfortunately the code only allows integers to be entered in the datagridview.I have a windows form application which contains a datgridview.I need to enforce cell validations on the datagridview cells so that it does not accept negative values.1) Add a conditional statement in the event handler code to only execute when required.2) Detach the event hander before the unwanted event triggers and re-attach after.

I began by using the Cell Validating event which has a really nice Cancel Edit() method that will return the cell to its previous value.Gets a value indicating whether the caller must call an invoke method when making method calls to the control because the caller is on a different thread than the one the control was created on.(Inherited from Control.)Adjusts the height of the column headers based on changes to the contents of the header in the specified column, optionally calculating the height with the expectation that the column and/or row header widths will subsequently be adjusted.Adjusts the width of the row headers based on changes to the contents of the header in the specified row and using the specified size mode, optionally calculating the width with the expectation that the row and/or column header widths will subsequently be adjusted.Since you have not added your new row yet it should validate OK." yeah i think it is because of the line you have said above how can i avoid this situation???thanxxxxxxxxxxx If you have attached an event handler to the Cell Validating event then it will always fire when focus leaves the cell.
