HI you can add item in combobox by a simple statement like:

ComboBox_name.Items.add("Item Name",index)

ComboBox_name:- any name given to Combobox
Item Name:- name of element to be added
index :- index to which its position.

hi frnds..
i have same query but i want to use Add Range Method to fill me combo box..
please guide

A thread is available for this Issue.
Here are both the ways to fill a combobox.
By Add() and Addrange()
By Add()

combobox1.Items.Add("Sunday")
        combobox1.Items.Add("Monday")
        combobox1.Items.Add("Tuesday")
        combobox1.Items.Add("Wednesday")
        combobox1.Items.Add("Thursday")
        combobox1.Items.Add("Friday")
        combobox1.Items.Add("Saturday")

By AddRange()

Dim days() As String = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"}
 ComboBox1.Items.AddRange(days)

Well, it's many ways to do this apparently... But I wondered how it's possible to copy all the items from one ComboBox (for example in form1) to another ComboBox in form 2?
I write it something like this:

ComboBox1.Items.AddRange(New String() {Form2.ComboBox1.Items})

But I get an error like

"Value of type 'System.Windows.Forms.ComboBox.ObjectCollection' cannot be converted to 'String'.

How do I copy from one to another..???

[Havatra]

You just have to insert this:

Dim indx As Double = -1
Do Until indx = 70
    indx += 1
    ComboBox1.Items.Insert(indx, Form1.ComboBox1.Items.Item(indx))
Loop
