In general, it is better to use the Cell Parsing event whenever you need to convert/change the value in a cell.From within that event, you can indicate that the user's value is invalid by setting the Error Text value of the cell or row.Now, since so many books use the Cell Validating event, I wonder if there is not any gotcha (in display for example) with using the Cell Value Changed?I understand that the impact in performance should be irrelevant when using simple validation and conditional highlighting rules but I would as much prefer it not to run useless code everytime the user moves to another cell if it can be avoided.1) Add a conditional statement in the event handler code to only execute when required. Cell Validating -= new Data Grid View Cell Validating Event Args(dgv Sub Contractor_Cell Validating); it says that "Error 7 'System. hey what do ouy mena by the below private void data Grid View1_Cell Validating(object sender, Data Grid View Cell Validating Event Args e) if (adding Row) - is to call the button event for adding a new row is it every time the cell validating event triggers and a value is entered in the datagridview cell right??2) Detach the event hander before the unwanted event triggers and re-attach after. so when i click the add button the cell validating event triggers i have posted the cell validating event do you know how to solve this thanxxx code!!!
But there is no Error Text tooltip when the user moves the mouse over the Error Text icon.3.
We use Html View Define to arrange the columns in 2-row display. You can work around it by using the View Cell Formatting event: Hello Jack, Regarding: 1.
In this case, the row indicator and the columns will overlap with each other when the user scrolls the grid horizontally. I have updated your Telerik points for this bug report. Cell Validating event occurs only when a cell value is changed.
Something there is causing the cell validating event to fire. [Edit] The validating event is firing because focus is being moved from the DGV to the button.
I would like to manipulate a cell in my Data Grid View when it is validating so that if the user enters a value that is not valid for the database, but is easily converted to valid data, the program will change the value to an appropriate one.
