DataGridView Uncommitted New Row Cannot Be Made Invisible?
Nov 19, 2009
I have a DataGridView in my VB.net Form. I need to make some rows invisible based on a value. As there is not GridviewrowdataBound, I am trying to achieve it as shown in the below Code
Private Sub DataGridView1_CellFormatting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles DataGridView1.CellFormatting[code].....
When I try to do this I am getting the Uncommitted new row cannot be made visible error.

Im looking for an event that fires after a user enters a tabbed page and after the datagridview on that tabbed page is painted. BUT only fires on the load, not every single time the datagridview is painted. I am making rows in the datagrid invisible to the user based on wether or not a checkbox in the row is checked.
If I do this on the Tab_Enter event it paints the datagrid before I can loop through the records and change the visible property And if I do this on the Datagridview_Paint event it fires everytime the datagrid is painted (I only want it to fire once)

I am currently using a DevExpress (10.2) Banded GridView within my Visual Studio 2010 project. It works great except I was have an area where I allow the user to choose which columns they want visible or invisible. I noticed that if I make all the columns within a band invisible the band still remains and gives an empty column in my grid. I was wondering if there is some way to automatically

I have a DGV bound to a data adapter. I have a button that loads a form with a reference to the DGV row. When the form is loaded, it has a TextBox to type a value, that modifies one of the cells of the row. When the form closes, the cell.value is properly modified, but saving the DGV doesn't save the new value of the cell to the DB table. I'm assuming this happens because the DGV hasn't had physical interaction. Also, this particular field is a password field, so the whole column is being hidden from the view.It seems that a DGV change is noted by physically clicking in a cell and it stores some data telling the adapter there have been changes. The thing is, this is done on a per cell basis, and only if the cell has been clicked. Well, this cell is hidden, so even though the value will be changed, you could never click or select that cell.Is there any other way to force the DGV to accept changes made to it from outside actions of just assigning the cell.value from a button click and not phsyically changing it in the DGV?

I use a DataGridView to Add/Edit/Delete records from an Access database. Doing those 3 things is working just fine. When I try to update the database with the new Table data, nothing happens. I need to basically overwrite the table in the database with the data that was added, edited or deleted in the DataGridView. I opened the connection and got the table data like this

I have created a form that contains a DataGridView with data from a SQL Database. After viewing, the user will want to update checkbox fields in a single column of the DataGridView This action needs to update the SQL Database. I have set the "ReadOnly" to false on all the columns of the form and placed an "Edit" button on the form which changes the ReadOnly Property to True on the Column where changes would be allowed. How do I then set the binding to update the Sql with the changes made by the user?

I'm curently trying to get information displayed in a listbox from a selection made in a datagridview. For example a user selects an artist from the treeview control and it displays all the albums by that artist in the datagridview. Once a user selects an album all information for that album is displayed below the datagridview in either a listbox or listview control. I've tried dragging the conrols from the datasource and it' won't drag onto the listbox. What do I need to do to get it so that it will display album, artist and track information?

I have a MS Access database file that I can view with a DataGridView, but I can not save the changes made. User should be able to modify data, and when pressing the "Save" button, these changes should be reflected on the database. That is not happening.I know this is a common question, but I have read dozens of pages trying yo get this to work.

I made a birthdaylist. You can store birthdays in it, and it will alert you on the day a person has his birthday. To do that the program has to startup when the computer starts up, and give the alert if neccesary and then close itself again. This all works, but the mainform is visible in that period.

I understand the properties to change a button from visible to invisible, but I need to be able to have two buttons alternate visibility when the first button is clicked.It's for a game. The first button is to "Begin Game" and on open, the invisible button that sits over it is called "Begin Again" which I would like to only appear once the Begin Game button has already been clicked. This would then trigger the "Begin Game" to become invisible.
