[BindableAttribute(true)] 
[LocalizableAttribute(true)]

public override function get Text () : String

Property Value

The text associated with this control.

When setting the Text property, a null reference (Nothing in Visual Basic) or an empty string ("") sets the SelectedIndex to -1.

The following code example demonstrates how to initialize a ComboBox control by setting the Text property and using the AddRange method to populate the ComboBox. It also demonstrates handling the DropDown event. To run the example, paste the following code in a form and call the InitializeComboBox method in the form's constructor or Load event.


// Declare ComboBox1.
internal System.Windows.Forms.ComboBox ComboBox1;

// Initialize ComboBox1.
private void InitializeComboBox()
{
    this.ComboBox1 = new ComboBox();
    this.ComboBox1.Location = new System.Drawing.Point(128, 48);
    this.ComboBox1.Name = "ComboBox1";
    this.ComboBox1.Size = new System.Drawing.Size(100, 21);
    this.ComboBox1.TabIndex = 0;
    this.ComboBox1.Text    = "Typical";
    string[] installs = new string[]{"Typical", "Compact", "Custom"};
    ComboBox1.Items.AddRange(installs);
    this.Controls.Add(this.ComboBox1);
    
    // Hook up the event handler.
    this.ComboBox1.DropDown +=  
        new System.EventHandler(ComboBox1_DropDown);
}

// Handles the ComboBox1 DropDown event. If the user expands the  
// drop-down box, a message box will appear, recommending the
// typical installation.
private void ComboBox1_DropDown(object sender, System.EventArgs e)
{
    MessageBox.Show("Typical installation is strongly recommended.", 
    "Install information", MessageBoxButtons.OK, 
        MessageBoxIcon.Information);
}

// Declare comboBox1.
System.Windows.Forms.ComboBox comboBox1;

// Initialize comboBox1.
private void InitializeComboBox()
{
    this.comboBox1 = new ComboBox();
    this.comboBox1.set_Location(new System.Drawing.Point(128, 48));
    this.comboBox1.set_Name("comboBox1");
    this.comboBox1.set_Size(new System.Drawing.Size(100, 21));
    this.comboBox1.set_TabIndex(0);
    this.comboBox1.set_Text("Typical");
    String installs[] = new String[] { "Typical", "Compact", "Custom" };
    comboBox1.get_Items().AddRange(installs);
    this.get_Controls().Add(this.comboBox1);
    // Hook up the event handler.
    this.comboBox1.add_DropDown(new System.EventHandler(
        comboBox1_DropDown));
} //InitializeComboBox

// Handles the comboBox1 DropDown event. If the user expands the  
// drop-down box, a message box will appear, recommending the
// typical installation.
private void comboBox1_DropDown(Object sender, System.EventArgs e)
{
    MessageBox.Show("Typical installation is strongly recommended.", 
        "Install information", MessageBoxButtons.OK, 
        MessageBoxIcon.Information);
} //comboBox1_DropDown
