I''m using the currentcellvalidating event to perform some date and text validation. I''ve tested this scenario with having the event fire by clicking on another cell in the grid and validate only gets called once.In the case when the validation fails I display an error dialog box then set e. Forum_25Jan_40086I am using the Current Cell Validating method as you described above. Click in the cell so that there is a carrot in it 2. Click focus to another windows form not containing the grid that is validating. Also if I only have focus on the cell with the invalid data but no cursor in it then it too only fires validation once. Hi Mike, You can avoid this problem by overriding the forms Wnd Proc and handling the Form''s Activated/Deactived Events. Message m) Here is a sample Let me know if this does not help.Thx Mike Hi Mike, To validate the Current Cell, you need to handle the Current Cell Validating/ Validated/ Validate Failed Event Handler. Is there another work around you might be able to suggest?Here is the code snippet in the Current Cell Validating Event. I''ve mapped out the sequence of events for the three scenarios: Clicking on a different cell in the same grid: Current Cell Activated Current Cell Deactivating Current Cell Validated Row Leave Current Cell Control Lost Focus Current Cell Control Got Focus Current Cell Deactivate Failed Validate Failed Clicking on a control in the same C# Form: Current Cell Control Lost Focus Leave Validating Current Cell Validating Current Cell Validated Row Leave Validate Failed Enter Current Cell Control Got Focus Clicking on another visible form that doesn''t contain the grid: Current Cell Control Lost Focus Leave Validating Current Cell Validating Current Cell Validated Row Leave Validate Failed Enter Validating Current Cellvalidating Current Cell Validated Row Leave Current Cell Got Focus Validate Failed Enter Current Cell Control Lost Focus Current Cell Got Focus It''s clear there is a bug in how the grid behaves in the last scenario.i have written the code to validate the datagridview cell 2 , but whe i clicl cell 3 only the validation event is triggered for cell 2. how can i make the validation trigger so that the value of the current cell is seelcted. events are used to help stop the user from leaving a cell with a bad value.The Event Args usually has a Cancel property that if set to true will block the user from leaving the data entry field (cell, textbox, etc.).

WB data for lysates of He La cells treated with camptothecin (DNA topoisomerase inhibitor) and blotted for γH2A. ICC/IF image of He La cell stained for MAPRE1 (red, ab53358), tubulin (green) and nucleus (blue).
I recommend setting the Cancel property to true for invalid data as then the user focus will remain in cell 2. (inside your column test) hey thankxx but the thing is i have to click on another place in the datagrid view to trigger the event.
so if i select invalid date i have to click another place in the datagrid view for the error msg to to i avoid this and make the event trigger after the cell value is beign selected?????
