I 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.
I have a program that gets some information from the user and updates the database.I also have two DataGridView, OpenOrders and ItemsInOrder When the user click on a cell in the OpenOrders a CellChange event is triggered and it updates the ItemsInOrder grid view. Now after I update the quantity of a product i want to cause that CellChange event to trigger again in order to refresh the ItemsInOrder grid view.
View 7 RepliesI 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 RepliesThe 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?
I 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:

I have a datagridview with transaction bindingsource I want the datagrid to show the sorted rows only not all the records when i enter a value into a textbox and click button sort.
View 1 RepliesWhat I am trying to do basically is open an access query in a datagrid view and then be able to make changes to the datagrid and then save it back to the database.When I try to save:
Me.BindingSource.EndEdit()
Me.TableAdapter.Update(DataSet)
It says that update is not a member of the tableadapter... Why is that?
I am using a list<of T> as a data source for a datagridview and would like to handle the draw event of the datagridview to evaluate the string length of the column cell. If larger than a particular number then I would just do something like
cell.value = string.substring(0,(whatever number I need it to be)).
I have one data grid which contains a column which contains long string values. When I edit it, the text box which appears is very small. I want to increase the length of text box.
