double click event on listbox

[Jeff User]

Hi
Using .NET 1.1, C#, web app

I (actually our client) would like to be able to double click a
selection in a listbox and have it postback to server . There I would
want to access the item that was double clicked.

Any idea how to go about this?

Thanks
Jeff

Jeff,

I don't see a double click on a listbox. I been looking for this. I need
that functionality or possibly a Ctrl-Click

hope someone will give us an answer.

You will need to define this event by yourself - override the DropDownList:

public class myDropDownList : DropDownList, IPostBackEventH andler
{
public event EventHandler DblClick;
private const string _DOUBLE_CLICK = "dbl";

protected virtual void OnDblClick(Even tArgs e)
{
if (DblClick!= null)
{
DblClick(this, e);
}
}

protected override void OnInit(EventArg s e)
{
if (this.Page != null)
{
this.Page.Regis terRequiresCont rolState(this);
}
base.OnInit(e);
}

protected void Page_PreRender( object sender, EventArgs e)
{
string script = this.Page.GetPo stBackEventRefe rence(this, _DOUBLE_CLICK);
this.Attributes .Add("ondblclic k", script);
}

void IPostBackEventH andler.RaisePos tBackEvent(stri ng eventArgument)
{
if (eventArgument == _DOUBLE_CLICK)
{
this.OnDblClick (EventArgs.Empt y);
}
}
}

Please note that I do not have 1.1 handy - and the code above I compiled
from a similar control in 2.0 - so there might be some syntax errors - I just
wanted to get you an idea of how this could be accomplished.

I want to do this with a listbox, not a dropdownlist.
Is the procedure the same?

Thanks

Jeff,

The code that refers to handling double click event is not control specific
- you should be able to use it in ListBox.
