adding tooltip to dynamic controls [resolved]

[Sneeden]

I am adding a grid of command buttons to a user control. I am having trouble adding the tooltiptext at runtime. I have a tooltip control added to the user control form. Here is the code where I want to add it:

int x=0,y=0;
p_socks=new Button[iX,iY];
try
{
	for(x=0;x<iX;x++)
	{
		for(y=0;y<iY;y++)
		{
			//set socket's back color to default backcolor;
			//p_sockColor[x,y]=p_defaultColor;

			//no need to create sockets again
			if(socketsCreated)
				return true;

			//generate socket name
			string butName=x.ToString()+(char)(y+'A');

			//add new buttons
			p_socks[x,y]=new Button();
			this.Controls.Add(p_socks[x,y]);
			p_socks[x,y].Location = new System.Drawing.Point(10, 10);
			p_socks[x,y].Name = "butX"+x+"Y"+y;
			p_socks[x,y].Size = new System.Drawing.Size(20, 20);
			p_socks[x,y].TabIndex = 20;
			p_socks[x,y].Click+=new System.EventHandler(sockClickHand);
			//p_socks[x,y].tooltip????????????????
		}
	}
	this.Refresh();
	return true;
}

thx
