Visual Studio 2005 - ComboBox's Selected Value Changed On Lost Focus In .NET?
Oct 12, 2009
I have a datagridview(dgv) with a DataGridViewComboBoxColumn(colLocation)
colLocation.AutoComplete = False
colLocation.HeaderText = "Stored to"
colLocation.DataSource = DB.getLocation()
[code]....
I added the colLocation to dgv."descirption" contains Unicode characters. I can see the comboBox correctly and choose the item.The problem is when the comboBox lost the focus, the value is changed to first item of the comboBox.
Updated:I found out that the ComboBox doesn't change the data when the DisplayMember is in English characters. It changes only when the DisplayMember is in Unicode chracter.

I have been trying to do this for ages and having no joy whatsoever.
I have a ribbon window of the following hierarchy:
MainWindow
MainContent (Tab Control)
TabContainerViewModel
ViewModelBase
View model base has an ObservableCollection of tabs type ViewModelBase. The Tab Control itself is binding fine to these, displaying appropriate view models. I have 2 problems however, I want a "NotepadView" (Of type viewmodelbase) to be replicated numerous times (one view many view models).
At the minute, I have 4 views (NotePadViewModelx where x is 1-4) with corresponding viewmodels, this is because each view had the same text per tab. Now I have individual views per tab.
When I type into tab 1 and switch to tab 2, I lose what I typed in tab one when I click back.

I have a datagridview with a combobox column. The combobox column is populated from a collection. I begin to add data to the dgv, I select in the first row a value in the combobox and go to the second row. In the second row, when the combobox gets the focus, it appears 'V18', also the selected value before. Why? An on the other, when the combobox in the second row losts the focus, the combobox value is nothing. Why? Here are two images:

when the user clicks on the add button another form launches, which enables the user to add student info such as name, address, course, start date and end date, this information is then written to class when the ok button on that form is clicked, and then displays the data on the initial form in data grid. the user can add multiple entries and they are all displayed on the intial form and a the data grid is populatedwhen any of the rows in the displayed grid is selected, and the update button is clicked then the same form launches as the previous one and but this time its in the update mode and pre populates the form with the inital values.

I have to develop an application using MS Visual Studio 2005 or above with the following objective:
* The application should allow users to create as many new forms as they want and each form should behave like a MS Visual Studio WinForm. By saying that it should be a container for drag and drop of controls from the toolbox that I will develop....
* Once the user design's each screen to his taste by placing various controls on the form, he should be able to save the form as a screen. Of course I have to provide functionality for each of the controls such as if he drags a button on to the form, he should be able to specify what action it has to perfom when clicked when the application is put into run mode. Quite similar to regular windows form button.
* My application should have two modes: a DESIGN MODE, where user can drag, drop controls and specify what they should do when put into RUN MODE. This is quite similar to MS Visual Studio designer.
* Last but not least is to be able to access the application via the browser with the same look and feel his desktop version.

Is there a more efficient/easier way changing the backcolor of a control when it has focus and lost focus? Let's say I've got 10 text boxes. Right now I would have 20 different events...10 for Enter event and 10 for Leave event. Of course, entering would change the back color to "green" and leaving would change it back to "white".

I am currently translating a windows form application, written in VB6, to a webpage written in Visual Studio 2010. In VB6 it is easy to find out which control has focus on the form using '.getFocus()'. I have come to the conclusion it is not that easy, if at all possible, in vb2008.

I have a textbox on a form that when it loses focus it updates other text boxes on the form. But before it updates the other textboxes I check the input value in the textbox lostfocus event if it is undesired I return focus to the the textbox and alert the the user with a msgbox. However where my problem is, is that when the cancel button is clicked I don't care what the input in the textbox is because the changes are being canceled but if the value is undesired the it keeps returning focus to the textbox instead of canceling the changes. Is there a way to see what control was clicked on before or in the lost focus event? Can't seem to figure it out tried enter and leave events but no luck!
So for example something like this...
Code:
Private Sub TextBox1_LostFocus(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.LostFocus
If Control that was clicked <> btnCancel then

I am working on a form that allows the user to open a plaintext file into a rich text box.The user can search for a word using a textbox and a find button. The word is then highlighted. I cannot figure out how to keep the word highlighted or selected when I type in my replace box or click anywhere else on the form, the word is no longer selected. have a replace button, which will replace any single instance of a word. But my replace all button is supposed to replace all of the words, and count the number of replacements it makes and display that number in a message box
Public Class Form1
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

I have a form with 7 textboxes, all describing different attributes of a used car. In the shared leave event of my tb's, I need to code a case statement which determines the particular textbox that lost focus. I then need to perform different tasks which I understand how to do, and I don't think they matter to my question.
I understand how to give focus (txtTextBox.focus()), but how do you tell if something has lost focus?
And furthermore, how would you use that to structure the case statement?

I had previously made a simple Pong program which use keyboard to control. The control includes "s" to start the game, "p" to pause, "r" to resume and left, right to move the paddle specifically. This program work with little problem. The first problem I encounter is if I insert even one single button on the form to display instruction, the arrow keys will no longer work. But I get around it by using Menu Strip instead.
Then, I am required to put this program, among others into a MDI program. And this is where the problem happen. If I have this Pong game loaded, and I press "s", "p", or "r" keys, it have no problem, but if I press the "left" or "right" keys, it will not move. I am speculating that maybe the focus is lost when arrow keys is pressed or something similar, but I have absolutely no idea what is happening. I have tried giving focus back to the form if focus is lost, but to no avails. And this is the code for the movement of the paddle. This reside on a form, the movement itself is passed to another class. The MDI parent is on another form. [Code]

I am using VB.NET to build my application. And in my application has a lot of Forms. It doesn't use MDI Parent Form, but I use another simple Window Form (I named it frmMain) that I suppose it is my MDI Parent Form. When frmMain load, windowState = Maximized. And when I open a Form (example: I named it frmCustomer) that I suppose it is my child Form, and I set its properties (frmCustomer.TopMost=True) when it load, so it always on the top. But When I change to open another application such as Ms. Word or Mozilla Firefox... the frmCustomer is still on the top. how can I know my frmMain lost focus?

I need some kind of structure where I can store data with a unique copy of each item (I mean that there can't be more than one of each). Something like the "set" type in the good ol' Turbo Pascal.
I know Visual Studio 2010 has the SortedSet data type, but I can't find something like that in Visual Studio 2005. Is there anything I can use for this purpose?
