View 5 RepliesDatagrid New Row Cell Validation - Validate Empty Text And Indicate Error On Cell?
Jun 1, 2010The problem is that if you never enter anything into a cell for a new row then that cell is never validated. This is a problem because I have columns that should not be null. I am doing the check in the row level validation and storing the information about which cells are empty that should not be empty. The row level validation works fine and the row level validation error indicator goes on,(red exclamation mark at the beginning of the row) but I also need a visual indicator on the individual cells that are in error.
I am thinking that setting the HasError property for the cells that are in error should cause them to display n error style (the default red border). Is there a way to this this either from XAML (perferably) or from code?Alternatively I could cause those cells to re-validate when the row editing is finished. Does anyone know how to do this?
Prevent Moving To An New Cell In Datagrid If The Current Cell Is Empty
Aug 2, 2011I have a datagrid that will be accepting data from an external measuring device via the serial port. The grid is also open to editing records as well. Part of the process of making this grid user friendly is to intercept the "enter" key and move to the next cell until there is a value in the cell. This is only for some cells, other cells can be blank. I have worked out how to intercept the "enter" key from another post on this forum. Here is the code:

Disable Excel Format Cells?
Jul 13, 2011I has some vb.net code to export some data into Excel format. I had set one of the column to date format. But I want to avoid user from changing the format because they can easily right click the Excel cells, and choose Format Cells. How can I disable this option in Excel via vb.net code so that user will always follow my format?
worksheet.Cells(intCnt, 19).NumberFormat = "dd/MM/yyyy;@"
worksheet.Cells(intCnt, 19).Style.Locked = True
I use the above code to locked it but seems to be not working.

How To Compare Cells From Datagrid
Feb 26, 2009I'm trying to write an alarm clock application. When the program runs, a clock is displayed along with an 'Alarms' button. If the user presses the 'Alarms' button a new form opens with a datagrid with 2 colums, 'Time' + 'Message'. What I want to do is have the user enter a time and a message. The tick event should check the times entered in the datagrid, and when it reaches a time entered, the appropiate message is displayed.The problem I am having is how do I extract data from the cells of the datagrid. I want to compare it with the current time but am unsure how to do it. I've attached my sample code so far which just declares a time on the main form and shows message when time is reached.[code]
