View 1 RepliesI am making a custom ComboBox, inherited from Winforms' standard ComboBox. For my custom ComboBox, I set DrawMode to OwnerDrawFixed and DropDownStyle to DropDownList. Then I write my own OnDrawItem method. But I ended up like this:
How do I make my Custom ComboBox to look like the Standard one?
Update 1: ButtonRenderer After searching all around, I found the ButtonRenderer class. It provides a DrawButton static/shared method which -- as the name implies -- draws the proper 3D button. I'm experimenting with it now.
Update 2: What overwrites my control?I tried using the Graphics properties of various objects I can think of, but I always fail. Finally, I tried the Graphics of the form, and apparently something is overwriting my button.
Here's the code:
Protected Overrides Sub OnDrawItem(ByVal e As System.Windows.Forms.DrawItemEventArgs)
Dim TextToDraw As String = _DefaultText
__Brush_Window.Color = Color.FromKnownColor(KnownColor.Window)

I'm trying to make an invoice program, but i made only the form view (blush).
1. how can i make the combobox to read it's own values from a list, but a list in which i can add or remove items?
2. i need a field which is like autonumber in Access for the invoices'numbers and it has to increase it's value every time i push Button2
3. I used a datagridview to write the goods I will sell, but the last column has to show the result of (column1*column2) but it's always empty. I'm using VB 9.0.
Using a DataGridViewComboBoxColumn, the goal is to make the ComboBoxes accept user's new items and also the possibility of choosing items that are already present.I'm aware of using EditingControlShowing event of the DataGridView to change the DropDownStyle of the DataGridViewComboBoxEditingControl at run time to allow this, but I'm wondering if this can be done at a lower level.
What I'm doing now is extending DataGridViewComboBoxColumn, DataGridViewComboBoxCell and DataGridViewComboBoxEditingControl, hoping to change the EditingControl's DropDownStyle in the moment I instantiate it. So far, no luck.The debugger shows the right assignment is being executed, but nonetheless, the DropDownStyle is popping at the EditingControlShowing (using the event for debugging purposes) as DropBoxList, not DropBox, which is the intent.
Here follow the classes:
Public Class DataGridViewComboBoxColumnALT
Inherits System.Windows.Forms.DataGridViewComboBoxColumn
Public Sub New()

I have a combobox linked to a table Checklist (ID, Checklistname, and several multivalued fields). I want to have my subform display data from different tables based on my combobox selection "checklistname". All the tables are imported Excel files with the same fields and field types (ie. Discrepancy, reference, reference paragraph, category). How do I get my subform to requery based on the combobox selection? Or is there another method when working with "outside tables"? Import good/bad? Make new table? I have about 20 tables, if importing but only need particular data to save/store in my main table, and I need to know which table it came from.

I have a combobox on an Excel worksheet that I can tab into, then pick my data (located on another worksheet) after activating the "arrow". But the tab or enter key does not allow me to navigate away from the cell after it is populated. The only action that allows the user to move to another cell is by mouse/click to another cell. I am trying to make navigation through though worksheet as user friendly as possible.I can't seem to find any sample code that will take the focus away from that cell using Tab or Enter.
I have no problem with ListBoxes created using the Data Validation method but I have to create a ComboBox control on the active worksheet in order to return the data chosen (in this case a code that corresponds to a description). If this was a Form I wouldn't have any problem as the properties would allow me to set that up, but this is essentially a spreadsheet I've inherited and the current users do not want to go to a Data Entry Form.
I have an array of comboboxes on a form. They are declared at the beginning. I wish to make these global variables so I can access them in another form. This does not appear to work.

Where O1 O2 etc are the names of my comboboxes on this form. I wish to be able to address them from another form like so
