Force The Fill Event To Fire Everytime When Click The Combobox?
Dec 16, 2008
I am having a problem with data in a combobox not being refreshed (using VB.net 2005 by the way). Right now I have a windows application with several forms. I have a Template form that contains the cboActivity combobox. This combobox is filled with data from a SQL database. I also have an Activity form. This form allows me to enter new activity information and save it to the database. If I load up the Template form, click the cboActivity combobox, the Fill event is triggered and my combobox is filled with the activity data from the database. But if I leave this form open, go to the Template, add new activity information, and save it...when I go back to the Activity form the combobox has not been update to contain the newly added data. Is there a way I can force the Fill event to fire every time I click the combobox?

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 have a multiline label that im trying to add a line everytime I click the button. Its basically adding a new CD track name, CD minutes, and CD seconds to each new line for everytime the user inputs the given information:
1 Track_Name1 3 min. 13 sec.
2 Track_Name2 2 min. 34 sec.
3 Track_Name3 3 min. 01 sec.
.
.
.
But it keeps adding the "new" line in the position of the old one, so its only displaying on 1 line. I tried using a vbCrLf, but I might have it in the wrong spot?
heres what I got...
Private Sub btnAddCut_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddCut.Click
cutCounter += 1
[Code]...
The cutCounter is obviously the track number, and it clears the current info for the new information.

I'm converting an old VB form to .NET, and there a few Buttons which each have a corresponding ComboBox hiding behind them. The previous behavior was that you'd click the Button, and that would trigger the ComboBox behind it, which would then drop down a selection list. I believe the idea was to have a static color and text label (which cannot be a selectable option in the drop-down list), with the functionality of a ComboBox.
Now, in VB.NET, clicking on the Button (which is directly over the ComboBox in the form) won't trigger the ComboBox dropdown anymore. However, if I make the ComboBox visible enough to click on, it will trigger the ComboBox.TextChanged event, and show the drop-down (they're set to the DropDownList style). I've set the event handler to handle both that event and the Button event. I've tried Button.MouseDown, Button.MouseClick, and Button.Click -- none of which have worked.
I did find the SplitButton control option suggested here, which would probably do the job, but I don't want to have to integrate a non-native control for just 3 buttons. I don't really want to mess with the control template, either

I have a simple program. It has a "Start" and an "Exit" button. When the "START" button is hit, I change the text on the exit button to read "STOP PROCESSING". Then I go into my processing loop. When the "STOP PROCESSING" button is clicked the first time, the program simply ignores it. When I click it the SECOND time, it gets control. I know this because I put a breakpoint in at the start of the subroutine.What could I possibly be doing to quash the firing the first time?

Is it possible to force a combobox to run it's validation event without moving the focus out of the ComboBox?
I need the event (or an event) to trigger when an item is selected with the mouse or an entry is typed into the combo box. I tried using SelectedValueChanged and SelectedIndexChanged however, these events do not fire if the user types a value that does not exist in the list source. I know I can change the DropDownStyle to DropDownList however, I still want the users to be able to type entries in the combobox (with auto complete).

I can't seem to get the Form.GotFocus event to fire.I have two forms - a main window and a debug window.The debug window will always be shown with the main window. But, I don't want the debug window to appear in the task bar - it's unnecessary.While my program is running, when I select another program, my main window and the debug window are placed behind the program that I selected. From the task bar, I can bring my program back to the front by clicking on it in the task bar. The problem is, that now my debug window is behind the other program.I have code that will "DebugWindow.BringToFront", and it works. But I need some way to run do this when the main form gets the focus.I do not wish to make any of my forms Modal. At least not permanently. If the solution is to change the modal property of the form temporarily, then that wouldn't be a problem.
I tried Me.Enter, Me.Activated, Me.Click and a few other events. Me.Click only works when I click within the Form window, not the form's title bar. Me.Activated caused problems - The code ran, but it would always end with the focus on the Debug window. When I tried to click on the main form, the Activated event would fire again, sending the focus back to the debug window.[code]
