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, IPostBackEventHandler
{
public event EventHandler DblClick;
private const string _DOUBLE_CLICK = "dbl";

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

protected override void OnInit(EventArgs e)
{
	if (this.Page != null)
	{
		this.Page.RegisterRequiresControlState(this);
	}
	base.OnInit(e);
}

protected void Page_PreRender(object sender, EventArgs e)
{
	string script = this.Page.GetPostBackEventReference(this, _DOUBLE_CLICK);
	this.Attributes.Add("ondblclick", script);
}

void IPostBackEventHandler.RaisePostBackEvent(string eventArgument)
{
	if (eventArgument == _DOUBLE_CLICK)
	{
		this.OnDblClick(EventArgs.Empty);
	}
}
}

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
