Question textbox.text = (combobox selection 1)
- Thread starter gho5t

There's no If statement required. You simply get the item selected and display it in the TextBox. The question is, do you want to display the same text in the TextBox as is displayed in the ComboBox or do you want to display some other aspect of the selected item, e.g. you have bound a list of Person objects to the ComboBox and it displays the Name properties and you want to display the corresponding DateOfBirth properties in the TextBox? If it's the former, you simply assign the Text of the ComboBox to the Text of the TextBox. If it's the latter then we'll need more details to give you an exact solution but it would look something like this:
Dim item = DirectCast(ComboBox1.SelectedItem, SomeType)
If item IsNot Nothing Then
TextBox1.Text = item.SomeProperty.ToString()
End If
I'm trying to learn the concept behind applying a variable to a combo box selection.
In an overall view of things I am eventually looking to have a system similar to the following:
(Please excuse my concepts being incorrect)
But I am looking to have a combo box selection load a set of different boxes.
So if selection1 in the combobox is selected then display "cubes.text", "qty1.text", "plastics1.text", "qty2.text"
or if selection2 in the combobox is selected then display "plastics2.text", "qty3.text", plastics3.text", "qty4.text"
Is this possible?
I believe i understand the concept behind what i wish to achieve just a matter of actually implementing it.
What class would I use?
I'm not 100% sure what you mean but I think that it's just a simple matter of data-binding. Try this:
1. Create a new Windows Forms Application project.
2. Add a ComboBox and a TextBox to the form.
3. Open the code windows and paste in this code:
Notice how selecting a Name in the ComboBox automatically displays the corresponding DateOfBirth in the TextBox? That's part of what data-binding can do for you.

New Person With {.Name = "Paul", .DateOfBirth = #2/2/1982#},
New Person With {.Name = "Mary", .DateOfBirth = #3/3/1983#}}
With Me.ComboBox1
.DisplayMember = "Name"
.ValueMember = "DateOfBirth"
.DataSource = people
End With
Me.TextBox1.DataBindings.Add("Text", people, "DateOfBirth")
End Sub
End Class
Public Class Person
Public Property Name As String
Public Property DateOfBirth As Date
End Class
4. Run the project and select different values in the ComboBox.Notice how selecting a Name in the ComboBox automatically displays the corresponding DateOfBirth in the TextBox? That's part of what data-binding can do for you.
Thank-you for this,
I was also meaning instead of displaying the combobox value into a textbox
I wanted to have different combobox selections place different textboxes and labels when selected.
My knowledge of the syntax is limited

In future, please simply attach an image to your post, so we can see it without having to leave the current page.
In that case, what you're actually trying to do is hide and show controls, e.g.

Me.Label1.Show()

End Select
