	   private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
		{

			ManagementObjectSearcher search = new ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapter");
			if (e.Node.Text == "NVIDIA nForce 10/100 Mbps Ethernet")


			foreach (ManagementObject info in search.Get())
			{
				try
				{


					//textBox1.Text=info["NetworkAddresses[]"].ToString();
					//textBox1.Text = info["IPAddress[ ]"].ToString();
					if (info["MACAddress"].ToString() == "00:1E:68:12:36:AF")
					textBox2.Text = info["MACAddress"].ToString();
					textBox3.Text = info["MaxSpeed"].ToString();
					textBox4.Text = info["AdapterType"].ToString();
					textBox5.Text = info["NetConnectionStatus"].ToString();
					textBox6.Text = info["Manufacturer"].ToString();
					textBox7.Text = info["GUID"].ToString();
				}
				catch (Exception)
				{ }
			}

			if (e.Node.Text == "Atheros AR5007 802.11b/g WiFi Adapter")
			{

				foreach (ManagementObject info in search.Get())
				{
					try
					{
						// if (info["Name"].ToString() == "Atheros AR5007 802.11b/g WiFi Adapter" || info["Name"].ToString() == "NVIDIA nForce 10/100 Mbps Ethernet")

						//textBox1.Text=info["NetworkAddresses[]"].ToString();
						//textBox1.Text = info["IPAddress[ ]"].ToString();
						if (info["MACAddress"].ToString() == "00:1F:3A:33:7E:D4")
							textBox2.Text = info["MACAddress"].ToString();
							textBox3.Text = info["MaxSpeed"].ToString();
							textBox4.Text = info["AdapterType"].ToString();
							textBox5.Text = info["NetConnectionStatus"].ToString();
							textBox6.Text = info["Manufacturer"].ToString();
							textBox7.Text = info["GUID"].ToString();
					}
					catch (Exception)
					{ }
				}
			}

Mod Edit: When you are posting code please use code tags like this.

put a break point on your catch or a display the exception

i think an exception in been thrown

You do realize that this:

if (info["MACAddress"].ToString() == "00:1E:68:12:36:AF")
	textBox2.Text = info["MACAddress"].ToString();
	textBox3.Text = info["MaxSpeed"].ToString();
	textBox4.Text = info["AdapterType"].ToString();
	textBox5.Text = info["NetConnectionStatus"].ToString();
	textBox6.Text = info["Manufacturer"].ToString();
	textBox7.Text = info["GUID"].ToString();

is only going to set textBox2.Text if the MAC address matches, right? The other entries -- if they exist -- will still be printed regardless.

try putting this in :

 catch (Exception err)
		{
			lblResults.Text = "Error caught in treeView1_AfterSelect function: . ";
			lblResults.Text += err.Message;
}

You'll have to add a label somewhere in your aspx code called lblResults to view the error message, or alternatively you can set a breakpoint on one of those lines of code and see the error in the debugger. Either way.. it doesn't help much to catch the error if your going to do nothing with it.

Also.. your if statement is only applied to the first statement in your list of textbox assignments. If you put braces in around them the entire output will be disabled for objects that do not pass the If check..

I would go one step further and code in the catch block to get the entire exception history. Code like:

catch(Exception err)
{
	while(err != null)
	{
		lblResults.Text += string.format("{0, }", err.Message);
		err = err.InnerException;
	}
}

When i remove the ""if condition from the Nodes then it works"". plz help me

If you don't put braces after an if statement only the next statement will be conditionally executed

 
		 if (info["MACAddress"].ToString() == "00:1E:68:12:36:AF")
		 {
					textBox2.Text = info["MACAddress"].ToString();
					textBox3.Text = info["MaxSpeed"].ToString();
					textBox4.Text = info["AdapterType"].ToString();
					textBox5.Text = info["NetConnectionStatus"].ToString();
					textBox6.Text = info["Manufacturer"].ToString();
					textBox7.Text = info["GUID"].ToString()
		  }

With braces all the statements get executed.
