Get An Event When A DGVCB Selection Is Made (without Leaving The Cell)?
Feb 26, 2010
I have a DGV with a CB column in VS2008. I would like an event when a DGVCB selection is made (without leaving the cell). It will probably have to be a DGV cell or row event but I can't find one that fires as soon as a DGVCB selection is made.

I'm using a matrix DataTable bound to a DataGrid. Cell edits aren't committed to the DataTable until a different row is clicked. How can I commit changes when any cell gets focus?

I have a relatively simple application that uses a series of combo boxes to ask questions. These combo boxes are bound to a table with 2 columns in it "RSN" and "RSN_ID". I'm using one table adapter to feed the form (and these boxes) once the main form is loaded. The problem I'm having is when I change one of the boxes, they all change to the same value, almost like they have the exact data source (which they do) but shouldn't you be able to make different selections even using the same table adapter? I have to run 20 queries at loadtime, or create 20 table adapters.
My current setup is like this:
Data Source: table that feeds the combobox
Display Member: RSN (from combo box table)
Value Member: RSN_ID(from combo box table)
Selected Value: Form's main binding source, unique to each combo box, where the selection is actually saved.
This works perfect when using one combobox, but as soon as I bound all of them I ran across this...

I am trying to create a dynamic dropdown after a dropdown has been selested (in asp.net vb)
For example: I have a dropdown question that asks: What brand of car do you drive (Toyota, Ford, Honda, Nissan, Chevrolet)
When the brand is selected I want another dropdown to appear under it with new chocies
For example: If Nissan is chosen, the second dropdown will be populated (from the database) with (Altima, Maxima, etc...)
And in some cases I would like a text box to appear, but If I can figure out the dropdown portion, I am sure I can figure out the textbox.

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 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 was thinking get the row index and then the cell index and using that to get the specific cell I need somehow but I do not know how to get the specific cell, so would this be easiest if so what command would I use to get the information from the cell, if not how would a better way to do this be?
I cannot find the way to get the row index if one exists so I am guessing it does not exist with this method so how would I go about getting the information from a specific column of a selected row?

Select Case e.KeyCode[code]....
This works. When the Enter button is pressed, it acts as the TAB button.The problem I am having is this only works if the datagridviewer is selected.As soon as I enter data into a cell (A cell is selected) the code wont work as it is not set for the cell keyDown event. The event does not exist, so I have to somehow create it.

I have a DataGridView with two columns. One is DataGridViewComboBoxColumn and other is DataGridViewButtonColumn. To capture the button click from the DataGridViewButtonColumn, i have written the CellClick event and it is working fine. However, this is not making my selection from the DataGridViewComboBoxColumn 'smooth'. What i mean is that i have to click on the combo-box twice for it to show the drop-down list. I have noticed that at every click, CellClick is fired. But only after the second click the drop-down pops out. What is the work-around for this?

I have a ComboBox that is databound to an ObservableCollection of strings. The ComboBox is also editable, so you can either enter in your own value or select one from the list. The issue I'm running into is the index of SelectedItem seems to be the index of the last item you selected when you've entered in your own value in the ComboBox, though it's -1 when you have IsTextSearchEnabled set to true. The problem is, if someone entered their own value and then decide to instead select the item on the ComboBox that had been selected before, the index doesn't change so the SelectionChange event doesn't fire. How could I get an event to fire in this situation?

I was wondering if there's an easy way to make a cell textchanged event for a datagridview, like you have the textchanged event for textboxes, an event that gets triggered everytime the user press a letter/number/symbol/backspace/space, so i can check in that event if the datagridview has changes and whether i should enabled my save button to save the changes made.
Or is there a better way to check whether i need to enable my save button?
