I have two forms, forms a and b. Each form has a combo box. The user selects an item from form A's combo box and saves their selection to a database by pressing a button. How can I display their combo box selection from form A in form B's combo box on form B's form_load event?
View 1 Repliesi'm new here and a little bit of a noob anyways i'm using VB.NET 2008 what i'm trying to do is list about 7 items in combobox1 and then depending on the selection list certain items in combobox2 but if the selection in combobox 1 changes then combobox 2 items need to change as well.

The insertion part of the form works great. But my problem is in the form load part......If i leave a field blank(Null),then perform Save operation,close the form after successful insertion and then reopen the form,then it retains the previous values during the form load......This is only in case where i leave a field blank in the previous data entry in the database.......But if i enter values in all fields then form load is working great.
I am trying have a data grid selection populate a form. I am new to this.Basically I have a connection persistance object and I would like to call that and call a stored procedure with the value of the selection. The datagrid is bound to an object.

Which is not it, the method i used only involved a few clicks per item to set up and it made it so what ever selection was chosen in a combobox for example was saved, and then that selection was loaded on the apps next run, i know i had to do something in the application setting/databinding area of the properties.
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?
View 1 Repliesi have four comboboxs that are dependant on each other selection.Its working fine but but what i want is to show "select an item" on zero selectedindex of each combobbox when form load.How can i do that???????what i have done is like as:

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?
View 1 RepliesOn my DataGridView one of the columns is set to a ComboBox. When I make a selection from this ComboBox the CellValue change Event is not triggered. What event is triggered when I do the selection?
View 1 RepliesI have several forms that are "reused," or vistited more than once per each time in the whole program. In VB6, using Form.Show() would show the form in its original state (the state is was when created in the designer). After closing this form (Unload Me), showing it again would still show the form in its original state.
I am coding in VB.NET 2008, and noticed that when I reopen a form I had closed during a session using my program, the form is in the state it was when I closed it (labels and listboxes filled with data), and not in its original state. I currently have the Form.Closing event filled with code to clear all of the controls, but I think that there must be a better way to "clear" or "reset" the form.
I am using VB.NET for Windows applications. What is the difference between Load event,Activate event and Enter event in the Form and in which order the above event is executed.
View 2 RepliesI'm trying to execute different code depending on the button clicked (button 4 or 5) on Form1, but when I click on button5 to activitae the code on the Form2's Load event everything is Ok, but when I click the back button to return to Form 1 and click on the Button4 to activate the code on the Form2's Load event again, it doesn't active the Form's Load event, is there a way to form the form load event every time I access it from Form1?

I have two forms. Form A and Form B. Form A has a datagrid that is populated from a SQL Database Table query. When a button is pressed Form B is launched that allows you to add a record to the database table. I need for the datagrid to be refreshed and show the newly added record when I close form B and go back to the parent.

I fear that there is something obviously wrong with my code, but I have come across a situation where the Form.Load event is not firing when I create and show my form. The form is not subclassed (as I've seen some problems with that in some searches), and I am not getting any errors thrown when I step through the code in the debugger.
I have a break point set on the IDE-created form load function (which does have the Handles MyBase.Load signature suffix) but the breakpoint is never reached and the form does display and work.The form is passed three arguments in the constructor but the IntializeComponent() function is called before anything else is done.

View 1 RepliesI have a form and initialize some global variables on its Load Event. There is a TextChanged event in one control (a textbox) that uses that value. The TextChanged event of the control is triggered before the Form's Load event even if I do not change anything on the TextBox, it looks like that happens when the control is loaded. Why is it doing it before the form? and what event can I trap in order to assure it's the first thing that happens?
Its as simple as this:
vb.net
Private Sub PackOutMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
ActiveFlag = False
[Code]....
My guess is that the msgbox should not appear until the flag is set to true somewhere in the code and then change the contents of txtUser, but it is shown before the form.
I'm creating a dynamic combo box and adding to a form. I'm trying to fill the combo box with a DataSource from an ArrayList and then selecting an item in the combo box based off a value from a property.Problem is, the combo box items don't get bound until after the Form_Load event has finished and the form is visible. So the combo box is empty when I try to set the selected index of the combo box. See code for what I'm doing in detail, and refer to comments in

View 1 RepliesI was having a problem with the debugger not stopping at breakpoints. After a lot of work that yielded no results, I realized that the problem was occuring in the form's load event and subs called from that event.
The problem is that it appears that the load event is not being called. Other startup forms in other projects in the solution seem to be working ok.
what could be keeping the the Load event from working?

I placed this in the form's load event. What I want is for this check to run before the form even loads.If an error occurs, the msgbox comes up and the form is never seen.

I am making the Transition to VB.Net (using VB.NET 2010 express) and I have a simple problem that is driving me crazy. I wish for my Form when it Loads, initialise and then call a sub and do some stuff eg perform a plot. If i place a button on the form and click it the sub works fine.This task was simple to do in VB6 but for the life of me I cannot get it to work in VB.NET. Has the Form-Load event changed in some way with .Net?
