use "key" and "value"

like...
System.Collections.Generic.List<KeyValuePair<string, string>> ComBoData = new List<KeyValuePair<string, string>>();

                        ComBoData.Add(new KeyValuePair<string, string>(xElm.GetAttribute("Title").ToString(), xElm.GetAttribute("ID").ToString()));

                        ddl_List.DataSource = ComBoData;

                        ddl_List.DisplayMember = "value";

                        ddl_List.ValueMember = "key";

Hope this is correct
ddl_List.DisplayMember = "Key";
ddl_List.ValueMember = "Value";
But the result is nothing :(
even in ddl_List.text it has the value

hmm... problem was you are trying to create new object ComBoData in every loop, so it always contains one value

change the code like...
try

	{
 

		System.Collections.Generic.List<KeyValuePair<string , string>> ComBoData = new List<KeyValuePair<string , string>>();

		foreach (System.Xml.XmlElement xElm in xDoc.DocumentElement.ChildNodes)

		{

			if (xElm.Name.ToLower() == "list")

			{

				ComBoData.Add(new KeyValuePair<string , string>(xElm.GetAttribute("Title").ToString() , xElm.GetAttribute("ID").ToString()));

			}

		}

		ddl_List.DataSource = ComBoData;

		ddl_List.DisplayMember = "key";

		ddl_List.ValueMember = "value";

	}

	catch (Exception ex)

	{

		MessageBox.Show(ex.Message.ToString());

	}
