C datagridview cellvalidating example validating technique in psychology
How can I stop that and have it triggered only after the user made some changes in the datagrid?
Added: It seems that changing from Cell Value Changed to Cell End Edit does the trick.
The Cell Validating event handler can clear the error text when the new cell value meets the validation criteria, but when the user reverts to the old cell value by pressing ESC, the Cell Validating event does not occur.
event, value calculates when I leave the next cell. Do not hesitate to contact me again if you have other questions. Row Index is coming back as a -1 on the a new first row. Question, how can I find what row I am working with. We will consider to improve this behavior in some of the feature releases.Hi, I'm using the cellvalidating event on a datagridview.
I can’t seem to get my Validate The Entry() function to return a 0 if the entry is either “” or NULL or string. I only need to validate certain columns in the datagrid, I don’t need to validate the EAN or the description for instance and yet the column index don’t seem to be logical?
In a lot of books and articles that I've read on this control, it seems to suggest that the appropriate event to handle for this is the Cell Validating one. However, this event triggers a bit too often for my tastes and I'm not sure it is required.
