ListBox problem

alexjjj

No, I mean, at runtime, can I enter data through the listbox in the page? ?

"You want to take out the value in listbox1 and put it in listbox2 to display it." Isn't that what you said?

Not quite understand what you mean. . .

Does this mean that at runtime, if there is a button key, then the input data is inserted into the listbox. If so, it is OK

Text box, plus a button can be placed in LISTBOX! !!

The following is a sample code I made for reference only:

public class WebForm2: System.Web.UI.Page
{
protected System.Web.UI.WebControls.TextBox TextBox1;
protected System.Web.UI.WebControls.ListBox ListBox1;
protected System.Web.UI.WebControls.Button Button1;
Ransom
private void Page_Load (object sender, System.EventArgs e)
{
// Place user code here to initialize the page
}

#region Web Form Designer Generated Code
override protected void OnInit (EventArgs e)
{
//
// CODEGEN: This call is required by the ASP.NET Web Forms Designer.
//
InitializeComponent ();
base.OnInit (e);
}
Ranch
/// <summary>
/// Designer supports required methods-don't modify with code editor
/// The contents of this method.
/// </ summary>
private void InitializeComponent ()
{
this.Button1.Click + = new System.EventHandler (this.Button1_Click);
this.Load + = new System.EventHandler (this.Page_Load);

}
#endregion

private void Button1_Click (object sender, System.EventArgs e)
{
this.ListBox1.Items.Add (this.TextBox1.Text);

}
}

Mainly set the event of the button:
private void Button1_Click (object sender, System.EventArgs e)
{
this.ListBox1.Items.Add (this.TextBox1.Text);

}

摩羯可乐

private void Button1_Click (object sender, System.EventArgs e)
{
this.ListBox1.Items.Add (this.TextBox1.Text);

}

correct

The main thing is that when the listbox is running, it can't directly input data like the text box. ?
