Datagridview cellvalidating old value
This is not rocket science and I don't understand why, by default, that Cell Value Changed (especially when associated with a checkbox) does not automatically initiate code for that property. First, you'll note that I've changed the column indices. Second, you appear to have overlooked my point tted Value is the value BEFORE the click, and (b) with a two-state checkbox the value resulting from the click will be the REVERSE of that, your test should be If Member? Specifically, the visual state of the checkbox clicked does not change until AFTER the messagebox has appeared and been dealt with. If I, however, click the cell but not directly into the box, the box does not update until exit of the cell. 4) Because of my limited use of a checkbox within a grid I did not realize the False/True worked in the same fashion but, yes the 0/1 could be ambiguous.
Several weeks ago I had the same issue with a dropdown column. I imagine that there may be a hidden column so that yours were right for your grid but, just on the basis of your description, "Chair? That's why, in my original demo and the code below, I used Debug. So, indeed, when something is wrong, and the message box shows, the checkbox doesn't show its new state until the user has moved off the checkbox to click on the messagebox. Is it suppose to work like a Message Box or Msgbox? I didn't see any specific issues with use of Message Box.
Debug writes to the Immediate window, not anywhere within the app itself.
One possible solution would be to do as suggested above and capture each key pressed from the cells in the “Quant” column. Format("Old Value New Value ", str Old, Control Chars. Do not hesitate to contact me again if you have other questions.Value) Is DBNull) Then Dim Due Date As Date Dim Hire Date As Date Dim str Result As Integer Due Date = CDate(.
Below is the code how I am trying to validate those i enter duedate less than hiredate, the program displays the error , "Date entered is less than hired date!!
The main reason is if i enter invalid value it should stop and focus again on that cell” If I understand this correctly, the user is using the arrow keys to go to the next column after they have changed a value in the previous cell.
