You should use dynamic sql query for that.. :)
like this,

SQL

declare @StrQuery nvarchar(max),@columnName varchar(150),@searchText nvarchar(max)
 select @StrQuery='select * from tableName where '+@columnName+' like ''%' + @searchText+ '%'''
 exec(@StrQuery)

where @columnName has been passed from code behind from combobox and @searchText has been passed from textbox from code behind.. :)

Solution 2

put this coding to form load

con.Open();
cmd = new SqlCommand("select Eid,Ename from temp order by Eid asc",con);
cmd.CommandType = CommandType.Text;
dr = cmd.ExecuteReader();
if (dr.HasRows == true)
{
while (dr.Read())
name.Add(dr["Eid"].ToString());

con.Close();

textBox4.AutoCompleteMode = AutoCompleteMode.Suggest;
textBox4.AutoCompleteSource = AutoCompleteSource.CustomSource;
textBox4.AutoCompleteCustomSource = name;
}
