Mar 22, 2011I may have missed the solution to this problem, but in my database I have 2 columns that cannot be null and a system.NoNullAllowedException message is displayed if they are mt. I want to change this message to simply indicate that the cell cannot be null, instead of the huge message with all of the information which is of no use to the user. I cannot seem to find where to change this message. When the exception is thrown I would like to see the message say something like "Empty cell not allowed".

Datagridview Default Error Dialog?
Jul 13, 2011I have a d.g.v. with two columns. One is set as date and the other is set as decimal. If there is a row and a number is typed in the decimal column, you can delete it and leave the cell empty. However, the program will not let me delete the contents of a date cell and leave it empty. It just gives me the default error dialog saying that I need to put the contents in proper date form and it doesn't let me leave it blank.
How can I make it so that it allows me to leave the cell blank?

I check each cell but all its values are number and I can sort all the columns before I edit one cell. But when I tried to change the value of only one cell and sort the columns, the errors will show. Its weird because I only removed 1 digit of the cell value and I cant sort at all.

Error Provider On A DatagridView Cell
Feb 11, 2011I created a DataGridView called grid_LivingBenefits.Each time a cell is going to be edited, the program will validate that cell.Now, I have two subroutines that take care of that validation.these are: ValidateDataType() and ValidatePrimaryKey()
at the DataGridView CellBeginEdit, the program checks for which cell the user is editing.at the DatagridView CellEndEdit, the program calls the subroutines for validation. If an input is invalid, I want the program to show an errorProvider on that cell.I used MessageBoxes first to check whether the validations are working and I got no problem there. but when I tried to use errorprovider instead of a messagebox, there's a blue zigzag line under the grid_LivingBenefits.CurrentCell
