I have some text boxes in my form that takes data and saves the data to the database. There is a combo box on the form that loads data from a specific field of a database.
When I enter and save the new data (using the textboxes), the combobox doesn't show the newly entered data. I tried to refresh the combobox using code like combobox.refresh, me.refresh etc....to refresh the form but nothing is working.
The combobox only display the new data when I close the form and reload the form again. Anyway, the data loading in the combobox is done using datasource, displaymember, valuemember in the properties So, how can I make the combobox show the updated record (field)?
the combobox name is cboManager
the Displaymember: Mname
Here's the code
Private Sub frmAdmin_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'UserDataSet.Manager' table. You can move, or remove it, as needed.

The remarked area works fine when I'm accessing a specific table. I've successfully inserted the products_model field into the combobox too.

I have a strange issue when binding a combobox in a WPF window.I am loading a List object, to populate the combobox, through it's .ItemsSource, on Window Load, however, it does not populate.At least, not until the arrow is clicked on. Once the arrow is clicked on, the window freezes up, and after a minute or so, the 4000+ records are displayed in it.Now, the list gets loaded, however, when I click on the combobox it takes awhile for it to render, so how can I show a waitcursor while it is rendering the list?Here's the Xaml for it:
Private Sub CreateTask_Loaded(sender As Object, e As System.Windows.RoutedEventArgs) Handles Me.Loaded Using New WaitCursor _LA.Show() Me.tOrder.ItemsSource = GetOrderList()

1. directly on the form, and

I have a little problem that i want to show a "sub Combobox" with the help of super combobox. i don't know it is possible or not becux i'm beginner in VB.
I am trying to convert watever is in the ComboBox to a number. So say I select "Grey" in the ComboBox I want it to show a number in the file i am making. My.Computer.FileSystem.WriteAllText(TextBox_ChooseFolder.Text & "" & TextBox_ItemID.Text & "-" & TextBox_ItemName.Text & ".sql",<ComboBox Number Here>, True)

coding multi column combobox in a DataGridView cell. When I click the combobox cell from datagridview, It shows the multiple column such as Name, address and telephone. When I choose the item, it will return the value.
I have an editable ComboBox with a validation on the Text property to make sure manually entered info is valid.EDIT: All I want to do is populate the .Text property with the ValueMember of a selection rather than the DisplayMember I also have the .Items populated with valid entries having the DisplayMember and ValueMember set.My DisplayMember is a caption along with the data, and the ValueMember is the data itself.So Items might be:
I had a validation on the text which can also validate manual user input like "5ef6" The problem I'm having is that if the user selects an item from the combobox it populates the text field with the DisplayMember property (ex: "Foo - 1ab2") which will fail validation.I have tried to manually set the .Text property with the SelectedValue or the SelectedItem.Value on each of the three relevant combobox events to no avail.I would like that the .Text of the ComboBox get populated with the .ValueMember of the item when selected rather than the .DisplayMember
EDIT: I cannot validate by trying to extrapolate the value from the caption. I send the Text off to a service to be validated.
The user can manually enter something like "5ef6" which will pass validation.But when they select an item from the list, rather than manually entering it, the .Text property gets filled with the caption and not the value ... so it will contain "Foo - 1ab2" and that will fail validation. I cannot change the validation method to "infer" the value from the caption. I have no control over that service. All I'm after is the displayed value EDIT: Say a user selects "Foo - 1ab2" from the dropdown list, I want the text in the box to say "1ab2" EDIT: I have also tried to set the .Text property in code but I can't seem to make it work in any of the ComboBox events. how to programmaticly set the .Text property (and make it commit!) on a selection event they will also answer this question.
How Do I show the values from the dataset to the text box based on the selection from the combobox list i already populated the combobox my code is. [code]
