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:

View 2 RepliesDatagrid View Control Double Click On A Cell?
Jun 8, 2011I am creating an application for a college assignment called "Quote Manager" - the idea is a writer can save his / her favourite quotes, then go back to them and be able to print them.So I had this idea where all the quotes are loaded into a datagrid view on the main screen of the program and the user can double click on the quote he / she wants to load.
I don't want any code given I would also post what I have got so far but at the moment I am at work.What I want is to know how to manipultate the datagridview control so when a cell is double clicked a saved html page will load from a database.

View 7 RepliesDetect The Cell That's Right-clicked On In A Datagrid View When A Context Menu Is Being Used?
Aug 22, 2011I can do the context menu. When I'm NOT using a context menu, I can detect a right-click using the mouse click event.BUT how do I detect which cell that's beiing right-clicked on in a datagrid WHEN a context menu is being used (as the mouse-click doesn't seem to fire when a context menu is used - so I assume that the menu mechanism consumes the right-click message and doesn't pass it on so to speak).I have tried to manually call the context menu on a right-click, but then the context menu comes up at the wrong location.Rather than send a long listing of my multinedia program so far - here's something I tried as a separate proglet. I can send the long multimedia project listing if you like (so you can see why this it is important to resolve this little issue).

View 2 RepliesVS 2005 Current Cell Cannot Be Set To An Invisible Cell
Nov 16, 2009So I've got 2 unbound datagridviews, and am providing a push/pull interface where the user can move records from one to the other.
Grid A is read-only and the selectionmode is set to FullRowSelect. Grid B has a read-only DataGridViewTextBoxCell, an editable DataGridViewComboBoxCell, and an editable DataGridViewComboBoxCell.
Because the grids have different columns, but represent the same records, my notion was to create the datagridviews with the same column structure but hiding certain columns, and then just move the DataGridViewRows back and forth between the two, which seams to work.
The problem is that if I go into column 2 or 3 in grid B, I get "Current cell cannot be set to an invisible cell".
I can select cells in column A and I'm fine. It should be noted that on grid B the hidden columns are 4-7.
I know there's a problem when the CurrentCell attribute is set to a hidden cell, but I'm clicking visible cells. I inserted a breakpoint on the CellClick event of the DGV, and again for column 1 that works fine, but on columns 2 and 3 it looks like the error is occuring before the event even gets fired.
Is something in the background setting CurrentCell to one of the hidden cells before firing the event?
Datagrid 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?

Feb 12, 2010I have a form developed using the Dataform wizard (VS 2003). The Form shows Master-Detail data. The details are showen in a Datagrid. The form automatically loads the data in the Form_load event. Now I want to store the data from the datagrid to a datatable. I am using following code to get the details showen in the datagrid into a dataview. The objdsInvoice is the dataset that holds the Invoice And Invoice_Item data.
Dim DV As DataView
Dim tempDT As DataTable
tempDT = objdsInvoice.Tables("INVOICE_ITEM").Copy

Is there any better way to get the datagird values that are currently displayed into a datatable. The datagrid is bound to the details table in the Master-detail type dataset.
