Datagridview Bound To Bindingsource: Displaying Both Old Values And The New Values
Mar 23, 2011I bound datagridview to bindingsource. The bindingsource has its datasource a collection Called Rates which is a collection of Rate items. The rate object has a property called VALUE. I need the user to be able to edit different values for the collection; However, on the datagridview, i need to keep displaying on one column called OldValue the existing Rate value before the change while allowing the user to edit that value in a second column called NewValue.
In other terms, One colum OldValue will keep the existing values from the DB before being edited by the user, this column OldValue is readonly. Another column NewValue will display, the 1st time, the old value from the DB (similar to OldValue when we do the Fetch from the DB), but it`s editable column, so the user can modify each value in the column NewValue without overriding OldValue cells. For now, I bound both columns OldValue and NewValue to the same property VALUE of the Rate object,

Compare Values In Datagridview With Values In Database Before Inserting Into Database
Dec 15, 2010I am building VB.NET application that takes data from text files that are exported from a legacy DOS program. These are written to a datatable and displayed in a datagridview. Right now my code simply loops through the datagridview and inserts the data into the database (SQL Server). There is a requirement now that the client number must be checked before the insert to see if it exists in the database. If it does, then the value of one field (tax rate) is checked against the value of the field in the datagridview. If there is a difference, then the rate is to be updated in the database and the data that was in the database is to be written to a history table for audit purposes. If the client number is not there, then we are to do the insert (which is already written). I want to know what is the most elegant and efficient solution for this problem.
I need to compare what is in the database table with what is in the datagridview, update the history table for records that exist, and then insert new records.

How To Add Up Numeric Values In Datagridview
Jun 22, 2010I have a datagridview with 12 columns and 30 rows I want to use as a scoreboard for a game (no need to input or save data). Columns are for the players and rows for the scores of each turn played. Say player1 has a score of 10 I type it in in his column in row1, the 10 should show up in a label as his total. His next turn his score is 100, type it in row2 and the label should show 110 as total. Hope I am clear enough, is there anyone able to give an idea on how to do this (in code if possible)?

View 4 RepliesChecking Combobox Values In Datagridview?
Nov 4, 2008I want to check if two combobox values are equal. The comboboxes are in a datagridview.I found you need to use datagridview_EditingControlShowing to add a handler to the comobo boxes for selectedindexchanged. I can do this with this code.
Code:
Private Sub dgridRegisters_EditingControlShowing(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles dgridRegisters.EditingControlShowing
Dim combo As ComboBox = CType(e.Control, ComboBox)
[code]....
However, the message box comes up for every combobox in my datagrid when I change the index, not just the cmbPort2. I would like to have something like this...
If cmbPort1.selectedindex == cmbport2.selectedindex then
'do something
endif
..but it doesn't seem possible.

Datagridview In Dialog Reporting Old Values?
Oct 6, 2010I have a dialog that is displayed concurrently with the main form and it has a datagridview showing a list of x,y values. The user can actively change the DGV in the dialog, but if I reference the DGV from the main form, it will not capture the user changes, but report the original values that were in the cells. I'm sure there is some sort of refresh or update event I am missing, but I have tried all the VS suggested options for the DGV and the dialog that seem relevant with no luck.
